L2BEAT - The state of the layer two ecosystem

We're organizing Layer Two Amsterdam! Check it out! L2BEAT is an analytics and research website about Ethereum layer two (L2) scaling. We provide a comparison of the various Ethereum L2 systems available today. An important differentiator between L2BEAT and similar sites is that L2BEAT is committed to educating users and lists only projects that match our narrow definition of L2.

Road to privacy on Harmony

Road to privacy on Harmony What is privacy? Privacy = confidentiality (hiding payment amounts) + anonymity (hiding the identities of senders and recipients) Why privacy? Anyone can track your financial activity on-chain; swapping, transacting, voting, lending, borrowing, and more May cause mal...

EF-Supported Teams: Research & Development Roundup

We all have a lot to be thankful for this holiday season, from the first birthday of the beacon chain, to the successful upgrades over the past year and the incredible progress across the entire Ethereum ecosystem. As a highly productive year draws to a close, there are a few final gifts to deliver in the form of updates from many (15+!!)

Projects

An implementation of a bribery-resistant voting system built with zero-knowlege proofs on Ethereum, currently used by the clr.fund project to facilitate permissionless quadratic funding for public goods in the Ethereum ecosystem. Phase 1 of a multi-party trusted setup ceremony for zero-knowledge circuits on the BN254 curve.

Privacy Technologies

Privacy technologies stand to be one of the most important parts of the cryptoasset space. We have complied a list of resources that introduce concepts like confidential transactions, MimbleWimble, ring signatures, and zero knowledge proofs. If there is anything you'd like to add or change, you can tweet your feedback at @messari_crypto or email zack@messari.io.

Release announcement: Semaphore, a zero-knowledge gadget for Ethereum

We are excited to announce that Semaphore, a generic privacy layer for Ethereum applications based on zk-SNARKs, has been fully audited and is now available for developers to build upon. This open-source library allows any user to signal their endorsement of an arbitrary string, revealing only that they have been previously approved to do so, and not their specific identity.

L2 Stablecoin Mirror | zkLink

zkLink supports one-step stablecoin swaps with stablecoins and anchored assets (e.g, BTC, ETH) across different chains and of different kinds on zkLink Layer2 Engine, as efficiently and economically as possible. For example, on zkLink's Layer2 network, users can not only transfer their USDT on Ethereum (ERC-20) to BSC (BEP-20), but also swap their USDT on Ethereum to USDC on BSC.

Trustless, privacy-preserving blockchain bridges

In this paper, we present a protocol for facilitating trust-less cross-chain cryptocurrency transfers that preserve privacy of bridge withdrawals. We leverage zero-knowledge primitives that are commonly used to design cryptocurrency mixing protocols to provide similar functionality but across two or more blockchains.

Privacy on Mir

TLDR: As blockchain usage grows, privacy is becoming increasingly important. However, existing private smart contract designs like ZEXE aren't practical at scale due to state growth. Mir offers a new design for scalable privacy. As more financial infrastructure is built on decentralized protocols, users face an increasing need for privacy.

#Circom 2.0 is released! - Iden3 project blog

We're delighted to announce the release of the new version of Circom, the zero-knowledge circuit compiler. Jordi Baylina developed the first version, which he released in 2018. It was one of the first toolkits of zero-knowledge technology, and it has been successfully used in projects like Tornado Cash, Dark Forest, Polygon Hermez, Zkopru, Semaphore, TrustCommunity and many others, including of course iden3.

如何打造一款吸引公会的链游：Dark Forest 的另一种解读

同时，建议大家去关注分享的回放，主题是游戏性的策划，另外两位分享者，周衍老师和宋阳老师，他们分享的内容都是非常专业的干货，能够为想要投身链游研发的朋友提供直接且有效的帮助。 我是来自 RhizomeDAO 和DAppChaser 的 Erica，同时是一位科幻创作者。接触这个行业比较早，还是刚刚读大学的时候，在全身心投入加密世界之前，我从事的是行业研究相关的工作，四年前开始写区块链相关的科普作品，参与过一些区块链项目的孵化。 小学时，我开始玩网络游戏，是一些网游中公会战的积极玩家。在《天堂Ⅱ》的时代，我参与了个人游戏生涯中第一个公会；后来，担任过《飞飞》某个服务器最大公会的元老，记得那时最爱打的职业是巫师，升学期间，不幸终止于盗号。 兴趣使然，对于链游，我一直保持着比较密切的关注。 印象中，最早的「链游」，应该是2015到2016年，是一款卡牌对战游戏，算是古董级的链游，募集的是BTC，游戏币也不是Token，而是Coin。这个游戏有自己的链，现在已经彻底消失了，行情网站找不到任何信息，它的游戏道具是中心化的设定，和现在很火的 NFT 也没有任何关联。 （补充：这段是临时提到的，今天重新确认，这个游戏似乎已转手，成为了以太坊生态的 NFT 项目，但暂无起色。） 本次分享的主题是关于 Dark Forest 黑暗森林，一款灵感源于《三体》三部曲的去中心化区块链游戏，并由此出发，去谈谈链游如何从游戏机制上吸引公会，实现比较长期主义的良性发展。 Dark Forest 是一款基于零知识证明的去中心化实时战略游戏，是一个非常重数值的游戏。玩家所在的宇宙会一直生成和扩大，地图信息存储在玩家浏览器本地，需要用算力进行探图；如果你没有探索出攻击一方的领地，那么你无法知道到底是谁正在攻击你，敌人实力究竟如何。 目前， Dark Forest 仍处于测试阶段，更像是限时的链上电竞赛事和黑客松。以下是从0.5 到现在的每一轮赛事的规则，我们留到后面的部分具体举例。 下图是我在 v 0.6 第二轮时截的数据，大家可以看到，一旦 Dark Forest 开始新的一轮，整个 XDAI 网络的 GAS 消耗会突然提升，而且占比最大的就是 Dark Forest 的合约交互。 因为 Dark Forest 是开放式的去中心化状态，大部分玩家会使用社区开源和自己制作的插件，链上交互非常高频，排名靠前的玩家每轮游戏可能会消耗上百 XDAI 。 提醒：做链游，选择的链，会直接影响玩家的体验，需要考虑链的性能是否能支持游戏正常运转，链的生态是否能和游戏实现共赢。 想要开始玩 Dark Forest，需要准备邀请码和充足的

Introducing Plonky2 - Polygon | Blog

Polygon Zero's mission is simple: to use zero-knowledge proofs to scale Ethereum to a billion users, without compromising decentralization or security. Achieving this requires fast and efficient proof systems. Today, we're excited to share Plonky2, a major milestone for zero-knowledge cryptography. Plonky2 is a recursive SNARK that is 100x faster than existing alternatives and natively [...]
