ZK White Paper: Efficient ZK Proofs for Keccak

By Angus Gruen This post is part of a series of technical papers designed to better communicate to the Ethereum community the work of Polygon’s zero-knowledge (ZK) teams. We hope that everyone who’s interested in the inner workings of Polygon’s ZK projects, Ethereum itself, and cryptographic engineering in general will be able to learn something … Read more

Plonky2 is Now Open-Source

Earlier this year, Polygon announced Plonky2, a zero-knowledge proving system that represents a major breakthrough for ZK tech. Plonky2 offers two main benefits: incredibly fast proofs and extremely efficient recursive proofs. It’s a huge leap forward for the ZK space, and we’ve been blown away by the response from the developer community: people want to … Read more

ZKVerse: Polygon Zero Roundup

Sometimes it feels like crypto moves a little too fast. There are lots of talks and events during which the space’s key players and teams unveil new innovations or perspectives. Instead of being written down, too much of this important information gets scattered across the crypto chatterverse. It can be hard to keep track of … Read more

ZK and the Future of Ethereum Scaling

Arbitrum recently released a great post arguing that Optimistic Rollups (OR) represent the future of Ethereum, since they offer inherent scalability and cost advantages over ZK Rollups (ZKR). Their piece is well-written and worth reading. In the spirit of friendly debate, we’d like to present a different perspective. Polygon has committed $1 billion to ZK … Read more

Introducing Plonky2

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 … Read more

ZK-Proof Protocol, Polygon Nightfall, Launches on Testnet To Provide Low-Cost, Private Ethereum Transactions

Developed by Polygon in cooperation with EY, Nightfall combines zero-knowledge proofs with a ‘ZK-Optimistic Rollup’ to increase enterprise transaction privacy and reduce ERC-20 token transfer fees by up to 86%  Polygon, an Ethereum scaling platform onboarding millions to the Web3, today announces, in cooperation with global professional services organization  EY, that the Polygon Nightfall ZK-Proof … Read more

Polygon ZK Day Recap: Polygon Zero Reveal and Panel Talk With Vitalik

Polygon’s zk day event hosted in partnership with ETHGlobal on Dec. 9 was jam-packed with Zero Knowledge goodness. If you are interested in this technology and what it can do for Ethereum, check this out. The 3.5-hour ZK tour de force included the announcement of a $400 million deal with pioneering ZK startup Mir and … Read more

Polygon Takes A Major Lead In ZK Rollups; Welcomes Mir, A Groundbreaking ZK Startup In A $400M Deal

TL;DR: We are excited to announce that Mir, a startup building groundbreaking ZK tech, is joining the Polygon family in a $400M* deal. Mir gathered a team of talented cryptographers and engineers, and after almost two years of work developed the world’s fastest ZK scaling technology. The Mir team is now joining Polygon in order … Read more
