Monthly Update: Parachute Social Liquidity Pools, Ivan(OnTech) Joins as Advisor, Townhall, Trending on CoinGecko, Covered by EllioTrades Crypto + Altcoin Buzz, …– 31 Jul – 3 Sept'20
Hola folks! Yesterday we got caught up with everything that happened in July 2020 at Parachute and ParJar. Today, I will be sharing news from August. Looking back at those five weeks, they were easily one of the most action-packed ones in the Parachuteverse ever. If you missed my note about the new format from yesterday: “…I thought it would be best to club all the Parachute news into monthly reports and publish them back-to-back over the next few days to catch up with the latest…For a change, we will be focusing on Parachute + ParJar news alone in these monthly reports. Because if we include news from our partner project in these, we might as well publish the Encyclopaedia Britannica”. In case you thought yesterday’s was a long read, boy are you in for a shock today. Make sure to get yourself a beverage and set aside an hour to go through all that will follow. So here’s goes the Parachute scrolls dating 31-Jul-20 to 3-Sept-20 –
31 Jul – 6 Aug'20:
$PAR became one of the top trending coins on CoinGecko this week. The token also received a perfect score on DEXTools. Pretty sweet! We crossed 2500 members in the Parachute channel after quite a while. But no sign of Ron yet. Haha. BrainiacChess Network ($CHESS) was added to ParJar. We got a surprise listing on Hotbit ourselves with an ETH and BTC pairing. $PAR was listed on CoinW exchange this week too. More details here. Looks like wrapping up a day at Parachute usually ends with steaks. If you ever thought otherwise, a look at the $PAR contract should dispel that doubt. A community vote was opened up to list the next token on ParJar. Congratulations to Chirag for winning this week’s Parena and taking home 6k+ $PAR. Neat! Everybody knows about the bitcoin pizza. But did you know about the bitcoin burger? Read all about AlBundy185's crazy BTC journey here. What a wild ride indeed!
AlBundy185’s BTC ride has to be a stuff of legends
Pic of Gian with Diamond Dallas Page taken from his epic WCW Thunder story (https://t.me/parachutetokengroup/395125). Spooky sent us!
Gian announced a temporary stoppage of Two-for-Tuesday to make way for the second annual Big Brother contest. Soon after, he opened up entries for the contest. Woot! Fans can also get updates and spoilers from the GC’s BB group. Gamer Boy hosted a “Random Gk” trivia in TTR this week. Naj hosted a Sunday “Mega Trivia”. Afful held a “General knowledge” trivia as well. Sebastian shared the new ParJar Gaming schedule for August. Yes, you read that right. 75k $PAR in the monthly prize pool. Woot! For this week's Friday creative prompt (#nottodaycovid) by Jason, Parachuters talked "about what you are doing to keep yourself sane during the pandemic" for some cool $PAR.
Alejandro’s betta fish collection is a sight for sore eyes
Elmar, these are all amazing!
Model ships made by Bada during the lockdown. Awesome!
Ivan (from Ivan on Tech) joined the Parachute channel this week. Looks like next few weeks are going to be super exciting! Doc Vic hosted a flash game in the Parachute War Zone for some cool $PAR prizes. Mario had an interesting idea. Change the ParJar display name to “ParJar Wallet” to actually reflect the true nature of ParJar. And voila! “ParJar” is now “ParJar Wallet”. Instant feedback implementation! We also finally got an unofficial price chatter group running. As we mentioned in the last update, Clinton released a limited edition shirt in the Parachute Store this week to commemorate the Liquidity Program on Uniswap. Some of the Parena merch had to be sunsetted from the store though. So if you grabbed some before that, you are now the proud owner of rare Parena merchandise. James from the Parachute Athletics and Running Club announced a Secret Challenge for 400 $PAR. Cap shared a sneak peek into what’s brewing behind the scenes. He also posted some experimental visuals for the website and for ParJar:
Cap’s creative spurts are super trippy! Pt. I
Trippy creatives from Cap Pt. II
7 Aug – 13 Aug'20:
ParJar did some heavy lifting on behalf of Uniswap this week when Uniswap got clogged but ParJar swaps were running smoothly. If you haven’t seen how swaps work yet, CF made another cool video tutorial. Following last week’s community vote, Enjin ($ENJ) won a spot to become the next swappable token on ParJar. DMM DAO’s $DMG token was listed on ParJar as well. Inputs from the community were taken for listing the next DeFi token on ParJar. A new tier was added for the Parachute Uniswap Liquidity Rewards Program this week. Last week’s incredible Parachute run on CoinGecko was noticed by many including DAO Maker and Blockfyre. We got word that Parachute was featured in Ivan’s (Ivan on Tech) private report meant for his closed group of subscribers. Word on the street is that Parachute was reviewed in detail in the Hidden Gems section of the report and received the highest score among all the projects covered there. Super cool! He also talked about Parachute in his latest video. Watch out for timestamps 42:23 and 47:48. And followed it up with another mention in next day’s video as well. Pretty cool! $PAR also saw some crazy movements and activity. And all this started while Cap was chilling on an Amtrack on his way to Vermont. Haha.
Cap shared this amazing view from Vermont
Check out the Sentivate gear in the Parachute shop. For this week's creative prompt (#donkeyart), Jason had Parachuters "find an image of a piece of art that particularly moved" them and explain how and why. Darren’s Mega Friday Trivia in Tiproom had a sweet 6300 $PAR prize pot. Peace Love (Yanni) hosted another quiz in TTR with some more cool $PAR prizes. Clinton’s charity For Living Independence (FLI) became Lumenthropy’s spotlight charity this week which means they will be matching all $XLM donations to FLI. Lumenthropy is Stellar’s charitable arm. The entries to Gian's Big Brother Contest closed this week with Gian starting to share updates on episodes and $PAR rewards to weekly winners. If you want to catch all the action, head over to the BB Group set up by GC. And the most amazing thing happened this week – As new folks were joining into the Parachute group, someone named Ender Wiggin chimed into the chatter and as we talked we figured that he was not only Cap's neighbour in NYC but was also my school senior. Parachute truly brings the world together! PARs & Recreation wants to create a Parachute foodies group. And if his posts are anything to go by (figs, blueberries, Ikura), it’s going to be a hunger-inducing channel. Doc Vic (from Cuba) announced the start of a team Deathmatch tournament in the Parachute War Zone.
Congratulations, Clinton!
Looks like an epic ParJar video is underway. Parachute was also covered extensively by EllioTrades Crypto this week. YouTuber CM TopDog too made an awesome video on Parachute where he talked at length about the project, the roadmap, the token and more. Saweet! After seeing Albundy185 struggle with pooling on Uniswap, Cap and Ice had a light bulb moment for an entirely new feature on ParJar that would make pooling social and fun. More details to be released over the next few weeks.
Jose’s epic new gif puts Cap’s lightbulb moment about social pools into perspective :D
Looks like Alexis’ neighbour is into Uniswap pools as well. Get it, get it? Haha
Congratulations on the new store, Hang! Folks who don't know, Hang is building a hempire. World domination next
14 Aug – 20 Aug'20:
As mentioned last week, Cap and crew had something cool brewing for folks who pool assets on Uniswap. Presenting Social Liquidity Pools (SLP) by Parachute. No more pooling/staking alone in silos. Get together with others doing what you love most – pool assets on Uniswap (either directly or through ParJar - upcoming), then stake the received liquidity tokens into SLPs on ParJar to get additional rewards and social bonuses like entry into VIP or premium token curated groups. Making Uniswap social! Click here to read about what’s next for ParJar and Parachute. The first Uniswap $PAR Liquidity Pool Rewards Program came to a close. All qualified poolers will receive their rewards in 2 months. DeFi superstar yearn.finance ($YFI) was added to ParJar this week for both sends/tips and swaps. Woohoo! Waifu in the house. After last week’s community inputs regarding the next new token on ParJar, a public vote was started. Uptrennd founder Jeff Kirdeikis’ latest project, TrustSwap ($SWAP), got listed on ParJar after winning that vote which got a shoutout from Ivan as well. So now we have a tongue twister on our hands. Haha. Cap also shared the first hints about $PAR governance. More details to be posted next week. Plus, Cap announced that he will be hosting a townhall next week. Stay tuned! Get your questionnaire ready. Like last week, Parachute chatter popped up in Ivan’s latest video this week as well.
Dang! What an amazing place, Victor
For all the mobile gamers out there, Tony set up a Parachute Corporation for the EVE Echoes game. Hit him up if you want to join. Naj hosted a Sunday TTR trivia with a 6300 $PAR prize pot. Gamer Boy held one as well. Darren’s Mega Trivia in Tiproom was super fun as always. Jason did an impromptu token giveaway so that fellow collectors could complete their ParJar collection followed by a mini contest to "guess the closest to the number of miles I am about to run" for some cool $PAR. Chris hosted this week’s creative Friday prompt (#adminfunday): “Using the profile image of any Parachute admin as inspiration, draw what you think that admin would like to do on the weekend”. And what an amazing video Hans (Pad of DeFi Chad). Haha! Super hilarious and fun.
Some of the radest #adminfunday entries. Clockwise from top left: Skittish, TyReal, Staph It!!, Yosma, Ik Now, Jeff, Chica Cuba, Jhang, Kuuraku
21 Aug – 27 Aug'20:
Ivan (from Ivan On Tech) joined Parachute as an advisor. Woot! Welcome to the Parachute fam. Here’s a sneak peek into what the first day discussions with Ivan as an advisor revolved around. The project got featured in France’s largest crypto news platform, Journal du Coin. Noice! Click here for the English translated version. As mentioned earlier, Cap hosted a townhall this week. If you missed it, you can catch up here. He also shared a rough draft snapshot of “how the governance and fee distribution contracts could look for ParJar Wallet”. Plus, some updates from this week and a big picture view at what staking liquidity through ParJar could look like. Parachute also got mentioned in another of Ivan’s videos this week.
Snapshot from the Parachute Townhall
In partnership with Sentivate, ParJar distributed $SNTVT tokens this week to 1500 people of whom 800 were new users. Sentivate hosted this drop for members of a specific group as a token of appreciation for their support. Reminiscent of the AMGO drop, this was a precursor of “how PAR drops + other token drops could work for our Social Liquidity pooling”. The $PAR Governance whitepaper was released and initial brainstorming started in the tokenomics group. Cap was also interviewed by YouTuber Money Party (@Edward_F) this week to talk at length about where we are at and where we are heading. We also received a super duper shoutout from CryptoTube in his latest video where he did a deep dive into ParJar and Parachute. Thanks a ton! Cryptovator did a cool feature on the project as well.
Cap added more changes to the site to show: \"ParJar wallet in action along with…the integrations\" + Big Picture
In this week's creative contest, Jason put up a #writingprompt: "...imagine you are a brand new intern at my new mega corporation...Today is your first day and you are told you need to present something about crypto to upper management...all you know is Bitcoin is a thing and some vague information about it. Pick a coin or general crypto subject and write a short story...None of the facts or material can be correct in your presentation...". Haha! After helping fellow Parachuters with their ParJar collection last week, Jason set up a collector’s group this week. If you have more than 30 of the coins/tokens listed on ParJar in your @parjar_bot collection already, send Jason a PM and he will get you in. Victor hosted a “Big Trivia” in TTR this week for 6300 $PAR in prizes. Afful held a quiz in Tiproom on “General Knowledge” as well. Check out these wicked new shorts in the Parachute Store based on Jose’s gif.
Epic stuff, Jose! Haha
Nice haul from the Parachute Beer Exchange, CF! Markus did you a solid
Boldman Stachs pointed out that $PAR had the highest Galaxy Score on social media analytics platform LunarCRUSH this week. Pretty neat! CF took note. And like Cap mentioned, it has mostly been thanks to him. Haha. And big up to Jesús (@JALBARRAN02) for making a ParJar guide video for our Spanish crew. You rock! Interesting results from the DeFi survey: majority of crypto folks are still DeFi-curious. A new community vote was thrown open for listing the next DeFi token on ParJar. Anyone who's been around a bit already knows that Clinton does some amazing work at his charity, For Living Independence, which creates assistive technology for disabled individuals. This week he shared some snaps of a build which now enables a lady in a wheelchair get upstairs in her home.
This is so wholesome, Clinton! Thank you for doing what you do.
28 Aug – 3 Sep'20:
ParJar was featured in Altcoin Buzz’s latest video. Noice! Click here and here to read some recent updates from Cap. After winning last week’s vote, Akropolis ($AKRO) became the latest token to be listed on ParJar. Woot! bZx crew gave some serious competition too. So we had to get them on ParJar as well. $BZRX was listed this week right after $AKRO. $PAR now has 7k on-chain HODLers. Saweet! Sentivate will be our first partner project to have a Social Liquidity Pool on ParJar. This is amazing! Time for another community vote to get a new project listed on ParJar – this time it is DeFi Pie v/s Ren v/s Proxi DeFi v/s Others. If you’ve missed all the latest Parachute-related videos, we have your back. Check this tweet thread to catch up. Naj hosted a Saturday Tiproom Trivia for 6300 $PAR in prizes. Congratulations to Maria for winning the latest Parena. 8k $PAR in the bag. Woohoo! And congo rats to Yanni as well for winning a special edition shirt from the Parachute store. Gamer Boy’s Big Trivia in TTR saw a ton of participation as always. The Parachute Fantasy Football contest is back! Chris set up the entry rules this week.
CF has done wonders for Parachute’s social metrics: “..+500% in our fi(r)st marketing month..”
Whew, what a month! And with that we close for August 2020 @ Parachute/ParJar. See you again with one more epic monthly update tomorrow. Cheerio!

Zano Newcomers Introduction/FAQ - please read!

Welcome to the Zano Sticky Introduction/FAQ!

https://preview.redd.it/al1gy9t9v9q51.png?width=424&format=png&auto=webp&s=b29a60402d30576a4fd95f592b392fae202026ca
Hopefully any questions you have will be answered by the resources below, but if you have additional questions feel free to ask them in the comments. If you're quite technically-minded, the Zano whitepaper gives a thorough overview of Zano's design and its main features.
So, what is Zano? In brief, Zano is a project started by the original developers of CryptoNote. Coins with market caps totalling well over a billion dollars (Monero, Haven, Loki and countless others) run upon the codebase they created. Zano is a continuation of their efforts to create the "perfect money", and brings a wealth of enhancements to their original CryptoNote code.
Development happens at a lightning pace, as the Github activity shows, but Zano is still very much a work-in-progress. Let's cut right to it:
Here's why you should pay attention to Zano over the next 12-18 months. Quoting from a recent update:
Anton Sokolov has recently joined the Zano team. ... For the last months Anton has been working on theoretical work dedicated to log-size ring signatures. These signatures theoretically allows for a logarithmic relationship between the number of decoys and the size/performance of transactions. This means that we can set mixins at a level from up to 1000, keeping the reasonable size and processing speed of transactions. This will take Zano’s privacy to a whole new level, and we believe this technology will turn out to be groundbreaking!
If successful, this scheme will make Zano the most private, powerful and performant CryptoNote implementation on the planet. Bar none. A quantum leap in privacy with a minimal increase in resource usage. And if there's one team capable of pulling it off, it's this one.

What else makes Zano special?

You mean aside from having "the Godfather of CryptoNote" as the project lead? ;) Actually, the calibre of the developers/researchers at Zano probably is the project's single greatest strength. Drawing on years of experience, they've made careful design choices, optimizing performance with an asynchronous core architecture, and flexibility and extensibility with a modular code structure. This means that the developers are able to build and iterate fast, refining features and adding new ones at a rate that makes bigger and better-funded teams look sluggish at best.
Zano also has some unique features that set it apart from similar projects:
Privacy Firstly, if you're familiar with CryptoNote you won't be surprised that Zano transactions are private. The perfect money is fungible, and therefore must be untraceable. Bitcoin, for the most part, does little to hide your transaction data from unscrupulous observers. With Zano, privacy is the default.
The untraceability and unlinkability of Zano transactions come from its use of ring signatures and stealth addresses. What this means is that no outside observer is able to tell if two transactions were sent to the same address, and for each transaction there is a set of possible senders that make it impossible to determine who the real sender is.
Hybrid PoW-PoS consensus mechanism Zano achieves an optimal level of security by utilizing both Proof of Work and Proof of Stake for consensus. By combining the two systems, it mitigates their individual vulnerabilities (see 51% attack and "nothing at stake" problem). For an attack on Zano to have even a remote chance of success the attacker would have to obtain not only a majority of hashing power, but also a majority of the coins involved in staking. The system and its design considerations are discussed at length in the whitepaper.
Aliases Here's a stealth address: ZxDdULdxC7NRFYhCGdxkcTZoEGQoqvbZqcDHj5a7Gad8Y8wZKAGZZmVCUf9AvSPNMK68L8r8JfAfxP4z1GcFQVCS2Jb9wVzoe. I have a hard enough time remembering my phone number. Fortunately, Zano has an alias system that lets you register an address to a human-readable name. (@orsonj if you want to anonymously buy me a coffee)
Multisig
Multisignature (multisig) refers to requiring multiple keys to authorize a Zano transaction. It has a number of applications, such as dividing up responsibility for a single Zano wallet among multiple parties, or creating backups where loss of a single seed doesn't lead to loss of the wallet.
Multisig and escrow are key components of the planned Decentralized Marketplace (see below), so consideration was given to each of them from the design stages. Thus Zano's multisig, rather than being tagged on at the wallet-level as an afterthought, is part of its its core architecture being incorporated at the protocol level. This base-layer integration means months won't be spent in the future on complicated refactoring efforts in order to integrate multisig into a codebase that wasn't designed for it. Plus, it makes it far easier for third-party developers to include multisig (implemented correctly) in any Zano wallets and applications they create in the future.
(Double Deposit MAD) Escrow
With Zano's escrow service you can create fully customizable p2p contracts that are designed to, once signed by participants, enforce adherence to their conditions in such a way that no trusted third-party escrow agent is required.
https://preview.redd.it/jp4oghyhv9q51.png?width=1762&format=png&auto=webp&s=12a1e76f76f902ed328886283050e416db3838a5
The Particl project, aside from a couple of minor differences, uses an escrow scheme that works the same way, so I've borrowed the term they coined ("Double Deposit MAD Escrow") as I think it describes the scheme perfectly. The system requires participants to make additional deposits, which they will forfeit if there is any attempt to act in a way that breaches the terms of the contract. Full details can be found in the Escrow section of the whitepaper.
The usefulness of multisig and the escrow system may not seem obvious at first, but as mentioned before they'll form the backbone of Zano's Decentralized Marketplace service (described in the next section).

What does the future hold for Zano?

The planned upgrade to Zano's privacy, mentioned at the start, is obviously one of the most exciting things the team is working on, but it's not the only thing.
Zano Roadmap
Decentralized Marketplace
From the beginning, the Zano team's goal has been to create the perfect money. And money can't just be some vehicle for speculative investment, money must be used. To that end, the team have created a set of tools to make it as simple as possible for Zano to be integrated into eCommerce platforms. Zano's API’s and plugins are easy to use, allowing even those with very little coding experience to use them in their E-commerce-related ventures. The culmination of this effort will be a full Decentralized Anonymous Marketplace built on top of the Zano blockchain. Rather than being accessed via the wallet, it will act more as a service - Marketplace as a Service (MAAS) - for anyone who wishes to use it. The inclusion of a simple "snippet" of code into a website is all that's needed to become part a global decentralized, trustless and private E-commerce network.
Atomic Swaps
Just as Zano's marketplace will allow you to transact without needing to trust your counterparty, atomic swaps will let you to easily convert between Zano and other cyryptocurrencies without having to trust a third-party service such as a centralized exchange. On top of that, it will also lead to the way to Zano's inclusion in the many decentralized exchange (DEX) services that have emerged in recent years.

Where can I buy Zano?

Zano's currently listed on the following exchanges:
https://coinmarketcap.com/currencies/zano/markets/
It goes without saying, neither I nor the Zano team work for any of the exchanges or can vouch for their reliability. Use at your own risk and never leave coins on a centralized exchange for longer than necessary. Your keys, your coins!
If you have any old graphics cards lying around(both AMD & NVIDIA), then Zano is also mineable through its unique ProgPowZ algorithm. Here's a guide on how to get started.
Once you have some Zano, you can safely store it in one of the desktop or mobile wallets (available for all major platforms).

How can I support Zano?

Zano has no marketing department, which is why this post has been written by some guy and not the "Chief Growth Engineer @ Zano Enterprises". The hard part is already done: there's a team of world class developers and researchers gathered here. But, at least at the current prices, the team's funds are enough to cover the cost of development and little more. So the job of publicizing the project falls to the community. If you have any experience in community building/growth hacking at another cryptocurrency or open source project, or if you're a Zano holder who would like to ensure the project's long-term success by helping to spread the word, then send me a pm. We need to get organized.
Researchers and developers are also very welcome. Working at the cutting edge of mathematics and cryptography means Zano provides challenging and rewarding work for anyone in those fields. Please contact the project's Community Manager u/Jed_T if you're interested in joining the team.

I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. Help greatly appreciated!

I posted this on /cryptotechnology . It attracted quite a bit of upvotes but not many potential contributors. Someone mentioned I should try this sub. I read the rules and it seems to fit within them. Hope this kind of post is alright here...
EDIT: My mother language is french (I'm from Montreal/Canada). Please excuse any blatant grammatical errors.
TLDR: I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. If you're interested, send me an email to discuss: [email protected] . Thanks in advance!
Hi guys,
For the last few years, I've been working on a decentralized legal-binding contract system. Basically, I created a PoW blockchain software that can receive a hash as an address, and another hash as a bucket, in each transaction.
The address hash is used to tell a specific entity (application/contract/company/person, etc) that uses the blockchain that this transaction might be addressed to them. The bucket hash simply tells the nodes which hashtree of files they need to download in order to execute that contract.
The buckets are shared within the network of nodes. Someone could, for example, write a contract with a series of nodes in order to host their data for them. Buckets can hold any kind of data, and can be of any size... including encrypted data.
The blockchain's blocks are chained together using a mining system similar to bitcoin (hashcash algorithm). Each block contains transactions. The requested difficulty increases when the amount of transactions in a block increases, linearly. Then, when a block is mined properly, another smaller mining effort is requested to link the block to the network's head block.
To replace a block, you need to create another block with more transactions than the amount that were transacted in and after the mined block.
I expect current payment processors to begin accepting transactions and mine them for their customers and make money with fees, in parallel. Using such a mechanism, miners will need to have a lot of bandwidth available in order to keep downloading the blocks of other miners, just like the current payment processors.
The contracts is code written in our custom programming language. Their code is pushed using a transaction, and hosted in buckets. Like you can see, the contract's data are off-chain, only its bucket hash is on-chain. The contract can be used to listen to events that occurs on the blockchain, in any buckets hosted by nodes or on any website that can be crawled and parsed in the contract.
There is also an identity system and a vouching system...which enable the creation of soft-money (promise of future payment in hard money (our cryptocurrency) if a series of events arrive).
The contracts can also be compiled to a legal-binding framework and be potentially be used in court. The contracts currently compile to english and french only.
I also built a browser that contains a 3D viewport, using OpenGL. The browser contains a domain name system (DNS) in form of contracts. Anyone can buy a new domain by creating a transaction with a bucket that contains code to reserve a specific name. When a user request a domain name, it discovers the bucket that is attached to the domain, download that bucket and executes its scripts... which renders in the 3D viewport.
When people interact with an application, the application can create contracts on behalf of the user and send them to the blockchain via a transaction. This enables normal users (non-developers) to interact with others using legal contracts, by using a GUI software.
The hard money (cryptocurrency) is all pre-mined and will be sold to entities (people/company) that want to use the network. The hard money can be re-sold using the contract proposition system, for payment in cash or a bank transfer. The fiat funds will go to my company in order to create services that use this specific network of contracts. The goal is to use the funds to make the network grow and increase its demand in hard money. For now, we plan to create:
A logistic and transportation company
A delivery company
A company that buy and sell real estate options
A company that manage real estate
A software development company
A world-wide fiat money transfer company
A payment processor company
We chose these niche because our team has a lot of experience in these areas: we currently run companies in these fields. These niche also generate a lot of revenue and expenses, making the value of exchanges high. We expect this to drive volume in contracts, soft-money and hard-money exchanges.
We also plan to use the funds to create a venture capital fund that invests in startups that wants to create contracts on our network to execute a specific service in a specific niche.
I'm about to release the software open source very soon and begin executing our commercial activities on the network. Before launching, I'd like to open a discussion with the community regarding the details of how this software works and how it is explained in the whitepaper.
If you'd like to read the whitepaper and open a discussion with me regarding how things work, please send me an email at [email protected] .
If you have any comment, please comment below and Ill try to answer every question. Please note that before peer-reviewing the software and the whitepaper, I'd like to keep the specific details of the software private, but can discuss the general details. A release date will be given once my work has been peer reviewed.
Thanks all in advance!
P.S: This project is not a competition to bitcoin. My goal with this project is to enable companies to write contracts together, easily follow events that are executed in their contracts, understand what to expect from their partnership and what they need to give in order to receive their share of deals... and sell their contracts that they no longer need to other community members.
Bitcoin already has a network of people that uses it. It has its own value. In fact, I plan to create contracts on our network to exchange value from our network for bitcoin and vice-versa. Same for any commodity and currency that currently exits in this world.

TweeBuck is about to launch... Exciting? Definitely!

TweeBuck is about to launch... Exciting? Definitely!
The concept of finance is not new, it has been in existence since the earliest days of the exchange. Everyone has the opportunity and ability to be successful if they have the right resources, however, one of the most challenging aspects of building a business is financing it and many often struggle in their endeavour to raise the capital required.
Over the years, the concept developed into a centralized system allowing users to trust their assets (money and any other forms of wealth) to 3rd parties with the goal of receiving monthly or yearly interest.
This concept was great while it lasted but as usual, the only thing that remains constant is change.
Cryptocurrency and Blockchain came into existence some years back as a medium to pay for services rendered via digital currency. Bitcoin, the very first Blockchain, was created but served as a one-way payment medium and nothing more. However, developers saw the vision that something more could be achieved using this same technology, but with more features being included. These were called smart contracts.
Smart contracts do not require both parties to be present, they are automated and use real-time data to generate the result.
Ethereum brought this to reality and a few years later, others saw this opportunity and started making use of it to build DeFi apps, which would later become more preferable to CeFi.

https://preview.redd.it/r29i9sgbbzu51.png?width=468&format=png&auto=webp&s=7234ba1a5ad36e13a057d60303c02cc4efa60a13
Decentralized finance, or DeFi for short, is a general term used to represent financial applications or platforms that are built using one or more Blockchain, that make use of smart contracts to create higher returns on investment.
DeFi alone is a great investment option, but the major challenge it has faced so far is a lack of users or a limited number of users whose sole aim is to increase their vested capital. Up until now, it has not been community-driven, which would create something far greater. Tweebaa intends to achieve this.
What is Tweebaa?
Tweebaa is the world’s only earning commerce platform. Its revolutionary multi-dimensional ecosystem utilizes a value-exchange model and provides everyone with the means and opportunity to generate a substantial income. Tweebaa empowers its users by applying their winning team's proven success methods with “DRTV (Direct Response Television)” and helps bring a global network of traffic to their product or business! Tweebaa has all the great communication features you would want within social networking and of course the best marketplace too! Tweebaa paves the way for users to earn money in a variety of ways whilst also providing the emotional, financial, and social benefits that are often unavailable; all this in one app! Whether you are a business, a student, a seller, a homemaker, an influencer, a labourer, or a contributor to society, Tweebaa rewards you every step of the way!

https://preview.redd.it/rbzc2hucbzu51.png?width=468&format=png&auto=webp&s=97bb0492ccf23673cfb671be1370bfcf4ef07fff
Over the years Tweebaa has distributed wealth to both investors and users alike via its token called TWEE and has remained at the forefront of trends and latest developments. Tweebaa is going DeFi (TweeB) and promises to create a revolutionary system the world is more than ready for.
What is DeFi?
The definition might vary when asked by different individuals, but they all come back to the same meaning; decentralized means to render services such as lending and borrowing with no 3rd party involvement, restrictions, delays, the line waiting, and long queues.
DeFi is currently the most talked-about project echoing around the crypto space. Many are raving about it, while some are still critical.
DeFi farming has to do with individuals providing some form of liquidity to the market which in turn creates returns and keeps the market active. It gained massive attention when it came into existence and is still active and a hot topic of discussion today.
Tweebaa is introducing a new token called TweeB which included all the features of a DeFi coin. Tweebaa users will be able to explore and make use of this newly discovered global network.
What makes TweeB so unique?
At the moment, decentralized finance is mainly directed to an investor's interest with the sole aim of investing or rather putting in money and waiting for results (short-term). One can argue that it has yet to actually become a general platform when compared to centralized finance like the banking system, which offers services for every type of person. TweeB plans to reach a much wider user base, not only including the general cryptocurrency investor pool, but also the entire global network available through Tweebaa.
Using Tweebaa’s existing community, TweeB will create something that is totally different and rewards all users, both depositors and borrowers.
Whether you provide liquidity, lend to the TweeB platform, or make use of its borrowing services by providing crypto supported collateral, users can yield returns, regardless of which direction they decide to take.
Combining the power of Tweebaa and TweeB, the more TiV a user holds, the more interest they will generate.
What is TiV?
TiV is an influence value, which reflects a user's contribution to the APP. People can increase their TiV by using the app in various ways including; adding and purchasing products, engaging and networking with other tycoons, inviting friends, and more.
There are many ways users can increase their TiV performance
  1. Buy & Sell products
  2. Invite more friends
  3. Having your posts liked, commented on, or shared
  4. Evaluating Products
  5. Suggesting Products
  6. Having your Tycoonplace being viewed for more than 30 seconds
  7. Follow 5 new friends
  8. Creating a new post

https://preview.redd.it/0e4fip7ebzu51.png?width=468&format=png&auto=webp&s=b81f13f4b676411adff523bc6a2b611d7f1d2e5d
In the field of DeFi in Tweebaa’s ecosystem, the TiV value is similar to the credit value and plays a vital role in relation to TweeBuck (TweeB).
What is TweeBuck and how will users be able to make full use of this platform?
TweeBuck (TweeB) is the next generation upgrade from its token holders. All potential changes, including adding new marks or adjusting system specifications (for example, leverage factors or interest calculations), must go through the proposal and voting process.
TweeBuck (TweeB) is a token which embeds 1:1 voting right to execute composite governance. Token holders of TweeB can simply delegate their voting rights of utility tokens on ERC-20 to their own or other people’s Ethereum wallets address.
How does TweeBuck plan to reward its users?
TweeB is basically a DeFi-based coin and it plans on providing more financial services, when compared to other types of decentralized finance platforms, using the following features and more.
  • Providing Liquidity (Liquidity mining)
  • Depositing
  • Borrowing

https://preview.redd.it/y8zh5tifbzu51.png?width=415&format=png&auto=webp&s=0ebe7a922ebba38b0e1733de2397b5578c8cf460
Liquidity provider
Basically, users will be able to provide TweeB liquidity on a ratio of 50/50 to whichever coin it is paired with, i.e. TweeB/ETH, TweeB/USDT, and more depending on users and what they prefer.
As a liquidity provider, decisions on which pair to trade TweeB with will be totally dependent on users as it should when referencing a decentralized network.
While the above is performed, liquidity providers get returns in TweeB tokens as more swap is carried out.
Deposit
As mentioned above, TiV plays a vital role when interacting with the Tweebaa platform. The more TiV you have, the more TweeBuck (TweeB) you will receive. The TweeBuck (TweeB) amount received will be based on 60% of the users Twee and 40% from their TiV.
By depositing assets to the Tweebaa platform, users will be able to generate returns that are paid based on the pre-calculated format using different scenarios.
More information regarding this can be found in the whitepaper.
Borrowing
Centralized systems like the banking sector, give out loans to customers and in return, those customers provide collateral which can include land, homes, and other assets. However, the world is going digital and so should borrowing.
TweeB allows users to provide collateral in cryptos like BTC, ETH, and other altcoins which then provide users with the assets they want.
They can provide collateral in BTC and take their desired coin to trade; this can be paid back and their vested collateral closed/removed.
Conclusion
TweeB token omics can be further broken down to self-governance. In terms of DeFi, this simply means users will be able to self-govern the TWEEB platform based on the vested amount they hold. This, in turn, creates a scarcer economy giving more value to the token.
Scarcity is one of many ways to provide value to an asset, take BTC as an example with only 21mil total supply. It has, over-time, created a self-sustaining market which depends on holders and how much they are willing to sell at that point in time.
The same can be said about TweeB. Holders will determine how much they are willing to sell or if they prefer holding it, they will have more scarcity and more value.
In conclusion, TweeB hopes to create a system that is both community-driven and investment-wise, resulting in a system that is far more prevailing than anything currently available.
While the future cannot be predicted, users are advised to carry out their own research before investing.
To increase the awareness of TweeB, different events will be hosted occasionally. To find out more and keep up to date, join the Tweebaa telegram channel(community) if you haven’t already.

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31
Submitted for consideration to The Great Reddit Scaling Bake-Off
Baked by the pastry chefs at Offchain Labs
Please send questions or comments to [[email protected] ](mailto:[email protected])
1. Overview
We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too!
Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know).
To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts.
1.1 Why Ethereum
Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract.
The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both.
Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice.
1.2 Why Arbitrum
While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools.
Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users.
We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth.
2. Arbitrum at a glance
Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes.
Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability.
Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow.
Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below.
Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn.
Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask.
Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract.
Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details).
Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users.
Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum.
Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain.
Limitations
Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals.
As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit).
Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here).
So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality.
3. The recipe: How Arbitrum Rollup works
For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents:
Arbitrum Rollup Whitepaper
Arbitrum academic paper (describes a previous version of Arbitrum)
4. Developer docs and APIs
For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/.
Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release.
5. Who are the validators?
As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators?
Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers.
Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators.
6. Reddit Contract Support
Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain.
Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain.
For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2.
Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios.
In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process.
To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum.
When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) .
The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform.
8. Benchmarks and costs
In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking.
Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here.
Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum.
On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support:
Over a 5 day period, your scaling PoC should be able to handle:
  • 100,000 point claims (minting & distributing points)
  • 25,000 subscriptions
  • 75,000 one-off points burning
  • 100,000 transfers
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.)
We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks).
Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c.
We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic.
Our model. Our cost model includes several sources of cost:
  • L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
  • Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
  • Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system.
Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.)
9. Status of Arbitrum Rollup
Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade.
Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet.
10. Reddit Universe Arbitrum Rollup Chain
The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo.
If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access.
11. Even more scaling: Arbitrum Sidechains
Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide.
While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic.
The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout.
Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator.
Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol.
Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest.
We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help.
While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined).
12. How Arbitrum compares
We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects.
Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
  • As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
  • All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
  • Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
  • Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks
While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components.
But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

Augur V2 is the next big step in Defi

This 6 month old Augur V2 video got me excited. I thought I’d share its value proposition, which I feel is currently being overlooked.
If you’ve been in the space for some time, you know what Augur is: a decentralized prediction market and the biggest (in ETH)/earliest ICO on Ethereum. Prediction markets allow for better forecasting by leveraging the power of incentivized wisdom of the crowd. V2 will soon launch with a revamped UI, cheap 0x orders and stablecoin integration. It’s set to become the most accessible, fair and open betting platform out there.
What you may not realize is its impact in the Defi space. Each market/prediction/question is represented by a token that can be traded in other Defi apps. This gives it incredible flexibility. Consider these possibilities:
This synergetic composability gets incredibly interesting when combined with other Defi legos. How about token sets based on bets between the ratios of active addresses on Ethereum vs Bitcoin? Why not make a Uniswap pair between a Real-T token and a bet against Detroit real-estate to hedge your position and gain transaction fees on the side?
Tokenomics
With growing interest over new Defi tokens, REP will no doubt position itself among the top. It’s one of the few that actually benefits from using a blockchain and has a utility that isn’t just governance related. Staked REP consensus is used to validate markets and collect fees in the process.
We’ve seen most successful Defi tokens pick up steam, especially in the past month, as mirrored by their sharp price increases: BNT +200%, KNC +90%, LEND + 70%, MKR +60%, LRC +140%. Augur V1 markets aren’t being used right now since the long awaited V2 is just around the corner. The repeated additional delays in V2’s launch date have kept its price comparatively low.
With that in mind, if one believes in the team’s ability to deliver and for Defi to continue growing, REP seems to be an extremely strong long term play. Whether you're a token holder or not, you'll likely see its contribution in many spheres of the Defi world. The above examples only scratch the surface of what it enables.

I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. Help greatly appreciated!

I originally posted this on /cryptocurrency. I just thought you guys might be able to help as well so I posted it as well. I didn't link to the original post because the bot here keeps deleting my post, even if I use the np link. Hope that's ok...
EDIT: My mother language is french (I'm from Montreal/Canada). Please excuse any blatant grammatical errors.
TLDR: I built a decentralized legal-binding smart contract system. I need peer reviewers and whitepaper proof readers. If you're interested, send me an email to discuss: [[email protected]](mailto:[email protected]) . Thanks in advance!
Hi guys,
For the last few years, I've been working on a decentralized legal-binding contract system. Basically, I created a PoW blockchain software that can receive a hash as an address, and another hash as a bucket, in each transaction.
The address hash is used to tell a specific entity (application/contract/company/person, etc) that uses the blockchain that this transaction might be addressed to them. The bucket hash simply tells the nodes which hashtree of files they need to download in order to execute that contract.
The buckets are shared within the network of nodes. Someone could, for example, write a contract with a series of nodes in order to host their data for them. Buckets can hold any kind of data, and can be of any size... including encrypted data.
The blockchain's blocks are chained together using a mining system similar to bitcoin (hashcash algorithm). Each block contains transactions. The requested difficulty increases when the amount of transactions in a block increases, linearly. Then, when a block is mined properly, another smaller mining effort is requested to link the block to the network's head block.
To replace a block, you need to create another block with more transactions than the amount that were transacted in and after the mined block.
I expect current payment processors to begin accepting transactions and mine them for their customers and make money with fees, in parallel. Using such a mechanism, miners will need to have a lot of bandwidth available in order to keep downloading the blocks of other miners, just like the current payment processors.
The contracts is code written in our custom programming language. Their code is pushed using a transaction, and hosted in buckets. Like you can see, the contract's data are off-chain, only its bucket hash is on-chain. The contract can be used to listen to events that occurs on the blockchain, in any buckets hosted by nodes or on any website that can be crawled and parsed in the contract.
There is also an identity system and a vouching system...which enable the creation of soft-money (promise of future payment in hard money (our cryptocurrency) if a series of events arrive).
The contracts can also be compiled to a legal-binding framework and be potentially be used in court. The contracts currently compile to english and french only.
I also built a browser that contains a 3D viewport, using OpenGL. The browser contains a domain name system (DNS) in form of contracts. Anyone can buy a new domain by creating a transaction with a bucket that contains code to reserve a specific name. When a user request a domain name, it discovers the bucket that is attached to the domain, download that bucket and executes its scripts... which renders in the 3D viewport.
When people interact with an application, the application can create contracts on behalf of the user and send them to the blockchain via a transaction. This enables normal users (non-developers) to interact with others using legal contracts, by using a GUI software.
The hard money (cryptocurrency) is all pre-mined and will be sold to entities (people/company) that want to use the network. The hard money can be re-sold using the contract proposition system, for payment in cash or a bank transfer. The fiat funds will go to my company in order to create services that use this specific network of contracts. The goal is to use the funds to make the network grow and increase its demand in hard money. For now, we plan to create:
  1. A logistic and transportation company
  2. A delivery company
  3. A company that buy and sell real estate options
  4. A company that manage real estate
  5. A software development company
  6. A world-wide fiat money transfer company
  7. A payment processor company
We chose these niche because our team has a lot of experience in these areas: we currently run companies in these fields. These niche also generate a lot of revenue and expenses, making the value of exchanges high. We expect this to drive volume in contracts, soft-money and hard-money.
We also plan to use the funds to create a venture capital fund that invests in startups that wants to create contracts on our network to execute a specific service in a specific niche.
I'm about to release the software open source very soon and begin executing our commercial activities on the network. Before launching, I'd like to open a discussion with the community regarding the details of how this software works and how it is explained in the whitepaper.
If you'd like to read the whitepaper and open a discussion with me regarding how things work, please send me an email at [[email protected]](mailto:[email protected]) .
If you have any comment, please comment below and Ill try to answer every question. Please note that before peer-reviewing the software and the whitepaper, I'd like to keep the specific details of the software private, but can discuss the general details. A release date will be given once my work has been peer reviewed.
Thanks all in advance!
P.S: This project is not a competition to bitcoin. My goal with this project is to enable companies to write contracts together, easily follow events that are executed in their contracts, understand what to expect from their partnership and what they need to give in order to receive their share of deals... and sell their contracts that they no longer need to other community members.
Bitcoin already has a network of people that uses it. It has its own value. In fact, I plan to create contracts on our network to exchange value from our network for bitcoin and vice-versa. Same for any commodity and currency that currently exits in this world.

I am paying 0.15 BCH if you can provide a link to Lightning Network whitepaper or announcement released in 2014 on its official creators' domain or mailing list. I know it exists, I remember it, but it was seemingly lost in the abyss of time. Can you find it for me?

Here is the WHOIS record for Lightning.Network domain:
Updated Date: 2019-02-02T01:41:17Z Creation Date: 2015-02-21T22:36:22Z Registry Expiry Date: 2020-02-21T22:36:22Z 
Here is video presentation of Lightning Network from march 2015:
https://www.youtube.com/watch?v=8zVzw912wPo
By February 2015 Lightning Network was already long under way.
I also remember the first draft of their Whitepaper and it was from end of 2014. Unfortunately it is not possible to find it currently.
Or is it? Can you find it? Prize awaits.
EDIT:
OK, most probably I am misremembering and off by few months, the publicly available whitepapers are from 2015 or later...
If nobody finds the older version until tomorrow, I will just split the reward between 2 people who convinced me of the truth.

Announcing r/Avalanche_, a positive, well-moderated, community-run subreddit for open and cordial discussion of Avalanche (AVAX), whose mainnet launches on September 21st.

Avalanche_ is the name of the cryptocurrency subreddit I have launched, to give the community of people learning about Avalanche and Avalanche Enthusiasts a place to discuss Avalanche free from toxicity and negativity.
This is an "unofficial" subreddit, in the context of Avalanche this means it is not owned or controlled by AvaLabs, which is the developing force behind the Avalanche project.
I am already up past 80 members in just a few days of social networking with my peers. I have also written an article about the subreddit, its purpose and origin, and my moderation strategies and philosophies, that you may read if you'd like. This article is posted in the subreddit.

What is Avalanche?

Avalanche is a cryptocurrency based on Team Rocket's whitepaper "From Snowflake to Avalanche" developed by AvaLabs, which is headed by the computer scientist Emin Gün Sirer, his cofounders, and a large global team of developers, community managers, and marketing evangelists.
Avalanche is named after the Avalanche Protocol, which is a specific and new consensus algorithm detailed in the original whitepaper. In my own words, I would describe it as a gossip/pandemic algorithm for a third-generation blockchain, utilizing multiple rounds of locally-random peer sampling, polling, and pre-state consensus. Essentially, this allows for a very fast and efficient consensus algorithm with mathematically sound properties. Proof of Stake is used as the underlying anti-sybil mechanism.
Some properties that you may find interesting:
1) Anyone can run a node. On your laptop, on your rasberry pie, it will all work with very minimum hardware requirements that basically all household computers meet.
2) Even if everyone runs these lightweight nodes, the Avalanche network has proven to process over 4500 tps. This is without high-grade hardware and also without sharding.
3) Transaction finality is under a second, with few exceptions that never take longer than about three seconds. By transaction finality i mean there is a practical 0% chance your transaction will be reversed, equal to that of around 6 bitcoin confirmations.
4) All validating nodes take part in the block-production process, and basically anyone can become a validator. There is no distinction (that I know of) between validating as a full node and validating as a block producer. Both are just validating and can influence the network.
5) The minimum amount of AVAX you need to validate is 2000, but this is parameterized, which means that the validators periodically are able to vote onchain to incrementally change it. There are other parameterized constants including the expensiveness of transaction fees.
Avalanche (AVAX) is also a robust and versatile smart contract chain that is fully equipped with it own virtual machine as well as the Ethereum Virtual Machine. All Ethereum applications can be ported over to Avalanche with no developer downtime.
Avalanche (AVAX) also has this unique and interesting property of inherent cross-chain same-asset atomic swaps, allowing for the creation of subnetworks with custom virtual machines, custom economics, custom anti-sybil mechanisms, basically the full scope of a custom blockchain utilizing the Avalanche consensus engine, fully interoperable with Avalanche's default chains. You can launch a subnetwork that still uses the Avalanche token, or you can launch one with its own token, really the possibilities are super open-ended.
Avalanche (AVAX) also has this interesting architecture of being kind of like a hybrid between a blockchain and a DAG. This one is hard for me to explain, so I will explain what I do understand. Avalanche actually is made of three default blockchains/networks, all synergistically working together and supporting the same native AVAX token:
Finally, a characteristic of AVAX that I absolutely love is how deflationary it is. Its the most deflationary cryptocurrency I have ever heard of. It has a maximum supply cap like Bitcoin (720M is max), all fees are burned like in Ethereum's EIP-1559, and there is incentivized staking that is open to basically everybody. I say the staking is incentivized, because you need to stake and validate in order to run a subnetwork, which can offer rewards (or be a business goal).

What is Avalanche_?

Avalanche_ is the cryptocurrency subreddit I am launching which allows for clean and open discussion of Avalanche as well as other cryptocurrencies. This subreddit focuses primarily on offering a moderated space to discuss Avalanche, where personal attacks are not allowed. Freedom of belief in opinion is protected, but anything that hurts people or is damaging to the culture of openness and positivity is prohibited and moderated. 99% of all moderation is performed by the moderator, and the other 1% is done by me and anyone else who may later be added to the team.
If you are wondering "Okay but why you?" I cannot give an adequate response besides "Because I care". I would point out that out of the 3000+ people participating in "Avalanche Hub" (which is AvaLabs' official incentivized community participation and marketing platform) i am #5 in terms of influence and my community contributions, but I suppose this is a bit anecdotal. I have written many articles in support of AVAX though, and this is a bit more material. I may share them below.
I have gotten a bit sophisticated with the automoderator tool, and I have done this because I want to protect noobs from toxicity and fighting. Essentially what I have done is 5 things, and together its created a toxicity neutralizing mechanism thats held up so far:
1) An initial vetting process that requires all accounts to have positive comment karma and be a week old, have 50 post karma, or 25 comment karma. This is a relaxed anti-spam measure. Currently parts of this are turned off, but they will be re-enabled in a few days. I did not make this measure too stringent because I want it to be easy for noobs to join and participate.
2) A well researched and extensive blacklist of indisputably toxic words, phrases, and domains that trigger instant removal.
3) A well researched and extensive greylist of fairly toxic words, phrases, and domains that trigger removal if the poster lacks a certain amount of post karma, comment karma, age, or goes reported.
4) A hierarchical and tiered report threshold where non-greylisted comments get removed on X number of reports, based on both post karma and comment karma. The lesser of these two make the weakest link.
5) An anti-doxxing protection algorithm which protects against credit cards, phone numbers, emails, and more from being doxxed. I myself have not created this, but I have been modifying it to fit the group.
I probably will not have to do much of any manual moderation aside from updating automoderator to keep it up to date with the lingo of people with bad intentions. However I am on Reddit everyday and I will be here to protect people from community attackers if its ever needed.
It is my belief that culture is absolutely crucial to the health of a project, and for this reason I am using both automated moderation and community moderation to curtail outsider attacks and infighting alike. As soon as the subreddit becomes a bit more active, it will make it easier for me to ask around the community for moderators.

Welcome to Avalanche

All are welcome in the Avalanche community. All I ask is that you don't intentionally and maliciously try to make others feel unwelcome. Avalanche is a global, decentralized, cryptocurrency and open source software for all to build on and utilize.
I am not a gatekeeper, but a mere member of the community which seeks to provide a positive and friendly platform for redditors to social network on. Links to relevant and official Avalanche community resources are in the "About" section of Avalanche_.
I hope to see many of you there! Let's change the world with this new, globally-scalable, deflationary, interoperable technology.
Build The Internet of Finance.

The Privacy Coin Guide Part 1

As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic.
If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties[1], and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? [2],[3],[4] Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?

FIRST THERE WAS BITCOIN

Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash. [5] Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis.[6] This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster.[7] This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain.[8] This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:

CRYPTONOTE – RING SIGNATURES AND STEALTH ADDRESSES

Used in: Monero and Particl as its successor RING-CT, Bytecoin
In December 2012, CryptoNote introduced the use of ring signatures and stealth addresses (along with other notable features such as its own codebase) to improve cryptocurrency privacy.[9] An updated CryptoNote version 2 came in October 2013 [10](though there is some dispute over this timeline [11]), also authored under the name Nicolas van Saberhagen. Ring signatures hide sender information by having the sender sign a transaction using a signature that could belong to multiple users. This makes a transaction untraceable. Stealth addresses allow a receiver to give a single address which generates a different public address for funds to be received at each time funds are sent to it. That makes a transaction unlinkable. In terms of privacy, CryptoNote gave us a protocol for untraceable and unlinkable transactions. The first implementation of CryptoNote technology was Bytecoin in March 2014 (timeline disputed [12]), which spawned many children (forks) in subsequent years, a notable example being Monero, based on CryptoNote v2 in April 2014.
RING SIGNATURES and STEALTH ADDRESSES

PROS

– Provides sender and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume
-Does not hide transaction information if not combined with another protocol.

COINJOIN

Used in: Dash
Bitcoin developer Gregory Maxwell proposed a set of solutions to bring privacy to Bitcoin and cryptocurrencies, the first being CoinJoin (January 28 – Aug 22, 2013).[13],[14] CoinJoin (sometimes called CoinSwap) allows multiple users to combine their transactions into a single transaction, by receiving inputs from multiple users, and then sending their outputs to the multiple users, irrespective of who in the group the inputs came from. So, the receiver will get whatever output amount they were supposed to, but it cannot be directly traced to its origination input. Similar proposals include Coinshuffle in 2014 and Tumblebit in 2016, building on CoinJoin but not terribly popular [15],[16]. They fixed the need for a trusted third party to ‘mix’ the transactions. There are CoinJoin implementations that are being actively worked on but are not the most popular privacy solutions of today. A notable coin that uses CoinJoin technology is Dash, launched in January 2014, with masternodes in place of a trusted party.
COINJOIN

PROS

– Provides sender and receiver privacy
– Easy to implement on any cryptocurrency
– Lightweight
– Greater scalability with bulletproofs
– Mature technology

CONS

– Least anonymous privacy solution. Transaction amounts can be calculated
– Even without third-party mixer, depends on wealth centralization of masternodes

ZEROCOIN

Used in: Zcoin, PIVX
In May 2013, the Zerocoin protocol was introduced by John Hopkins University professor Matthew D. Green and his graduate students Ian Miers and Christina Garman.[17] In response to the need for use of a third party to do CoinJoin, the Zerocoin proposal allowed for a coin to be destroyed and remade in order to erase its history whenever it is spent. Zero-knowledge cryptography and zero-knowledge proofs are used to prove that the new coins for spending are being appropriately made. A zero-knowledge proof allows one party to prove to another that they know specific information, without revealing any information about it, other than the fact that they know it. Zerocoin was not accepted by the Bitcoin community as an implementation to be added to Bitcoin, so a new cryptocurrency had to be formed. Zcoin was the first cryptocurrency to implement the Zerocoin protocol in 2016. [18]
ZEROCOIN

PROS

– Provides sender and receiver privacy
– Supply can be audited
– Relatively mature technology
– Does not require a third-party

CONS

– Requires trusted setup (May not be required with Sigma protocol)
– Large proof sizes (not lightweight)
– Does not provide full privacy for transaction amounts

ZEROCASH

Used in: Zcash, Horizen, Komodo, Zclassic, Bitcoin Private
In May 2014, the current successor to the Zerocoin protocol, Zerocash, was created, also by Matthew Green and others (Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, Madars Virza).[19] It improved upon the Zerocoin concept by taking advantage of zero-knowledge proofs called zk-snarks (zero knowledge succinct non-interactive arguments of knowledge). Unlike Zerocoin, which hid coin origins and payment history, Zerocash was faster, with smaller transaction sizes, and hides transaction information on the sender, receiver and amount. Zcash is the first cryptocurrency to implement the Zerocash protocol in 2016. [20]
ZEROCASH

PROS

– Provides full anonymity. Sender, receiver and amount hidden.
– Privacy can be default?
– Fast due to small proof sizes.
– Payment amount can be optionally disclosed for auditing
– Does not require any third-party

CONS

– Requires trusted setup. (May be improved with zt-starks technology)
– Supply cannot be audited. And coins can potentially be forged without proper implementation.
– Private transactions computationally intensive (improved with Sapling upgrade)

CONFIDENTIAL TRANSACTIONS

Used in: Monero and Particl with Ring Signatures as RING-CT
The next proposal from Maxwell was that of confidential transactions, proposed in June 2015 as part of the Sidechain Elements project from Blockstream, where Maxwell was Chief Technical Officer.[21],[22] It proposed to hide the transaction amount and asset type (e.g. deposits, currencies, shares), so that only the sender and receiver are aware of the amount, unless they choose to make the amount public. It uses homomorphic encryption[23] to encrypt the inputs and outputs by using blinding factors and a kind of ring signature in a commitment scheme, so the amount can be ‘committed’ to, without the amount actually being known. I’m terribly sorry if you now have the urge to go and research exactly what that means. The takeaway is that the transaction amount can be hidden from outsiders while being verifiable.
CONFIDENTIAL TRANSACTIONS

PROS

– Hides transaction amounts
– Privacy can be default
– Mature technology
– Does not require any third-party

CONS

– Only provides transaction amount privacy when used alone

RING-CT

Used in: Monero, Particl
Then came Ring Confidential transactions, proposed by Shen-Noether of Monero Research Labs in October 2015.[24] RingCT combines the use of ring signatures for hiding sender information, with the use of confidential transactions (which also uses ring signatures) for hiding amounts. The proposal described a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature which “allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation”.[25] RingCT was implemented in Monero in January 2017 and made mandatory after September 2017.
RING -CONFIDENTIAL TRANSACTIONS

PROS

– Provides full anonymity. Hides transaction amounts and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume

MIMBLEWIMBLE

Used in: Grin
Mimblewimble was proposed in July 2016 by pseudonymous contributor Tom Elvis Jedusorand further developed in October 2016 by Andrew Poelstra.[26],[27] Mimblewimble is a “privacy and fungibility focused cryptocoin transaction structure proposal”.[28] The key words are transaction structure proposal, so the way the blockchain is built is different, in order to accommodate privacy and fungibility features. Mimblewimble uses the concept of Confidential transactions to keep amounts hidden, looks at private keys and transaction information to prove ownership of funds rather than using addresses, and bundles transactions together instead of listing them separately on the blockchain. It also introduces a novel method of pruning the blockchain. Grin is a cryptocurrency in development that is applying Mimblewimble. Mimblewimble is early in development and you can understand it more here [29].
MIMBLEWIMBLE

PROS

– Hides transaction amounts and receiver privacy
– Privacy is on by default
– Lightweight
– No public addresses?

CONS

– Privacy not very effective without high volume
– Sender and receiver must both be online
– Relatively new technology

ZEXE

Fresh off the minds of brilliant cryptographers (Sean Bowe, Alessandro Chiesa, Matthew Green, Ian Miers, Pratyush Mishra, Howard Wu), in October 2018 Zexe proposed a new cryptographic primitive called ‘decentralized private computation.[30] It allows users of a decentralized ledger to “execute offline computations that result in transactions”[31], but also keeps transaction amounts hidden and allows transaction validation to happen at any time regardless of computations being done online. This can have far reaching implications for privacy coins in the future. Consider cases where transactions need to be automatic and private, without both parties being present.

NETWORK PRIVACY

Privacy technologies that look at network privacy as nodes communicate with each other on the network are important considerations, rather than just looking at privacy on the blockchain itself. Anonymous layers encrypt and/or reroute data as it moves among peers, so it is not obvious who they originate from on the network. They are used to protect against surveillance or censorship from ISPs and governments. The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other.[32] Its history dates back to 2003. Kovri is a Monero created implementation of I2P.[33] The Onion Router (Tor) is another anonymity layer [34]) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some[35]. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.[36],[37],[38]

Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero).
Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required.[39] There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.[40]

PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS

Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.
