ZK Research: Bignum Arithmetic for Zero-Knowledge Proofs

As part of our ongoing efforts to inform the Ethereum community about the efforts of Polygon’s zero-knowledge (ZK) teams, we will be posting a series of technical papers by our engineers and researchers. We hope that everyone who’s interested in the inner workings of Polygon’s ZK projects, Ethereum itself, and cryptographic engineering in general will … Read more

ZK Whiteboard Sessions: Your Dev-Driven Curricula for All Things Zero Knowledge

Polygon’s ZK ethos is all about collaboration, as embodied in groundbreaking, industry-reshaping projects such as Polygon zkEVM. In that spirit, Polygon has partnered with ZK Hack, a ZK-focused educational hub, to bring you the ZK Whiteboard Sessions. ZK Hack was created by the team behind the Zero Knowledge Podcast, hosted by Anna Rose. And through … Read more

Polygon ZK Roundup: Q3 2022

There have been several leaps in the zero-knowledge (ZK) space over the last five months, not least of which was Polygon’s rollout of a benchmarking ZK product. In our continuing series on the state of ZK, we look behind the bunting to bring you a recap of what Polygon’s ZK teams have been up to … Read more

PIL ZK Tooling is Now Open-Source

Polygon’s zero-knowledge (ZK) tech teams have recently unveiled the cutting-edge Polygon zkEVM, as well as open-source licensing for the revolutionary Plonky2 proving system. We are excited to announce yet another milestone: open-source licensing for our PIL toolkit.  We will be licensing the PIL toolkit jointly under the Apache2 and MIT licenses. Developers around the world … Read more

Polygon zkEVM Within Vitalik’s Framework: Gaining Clarity and Looking Ahead

The Ethereum community has recently seen a flurry of zkEVM (zero-knowledge Ethereum Virtual Machine) announcements, including the unveiling of Polygon zkEVM. Given how new these technologies are and how many different approaches are being tried, it comes as no surprise that there has also been a lively debate around key concepts and terminology. What is … 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

The Future is Now for Ethereum Scaling: Introducing Polygon zkEVM

We all know that Ethereum needs to scale, and we at Polygon believe that zero-knowledge (ZK) tech is the most promising pathway to get there. But that path has often seemed as if it would be long and winding. The conventional wisdom has been that the crypto space would need many years to develop Layer … Read more

ZKVerse: Deep Dive Into Polygon Hermez 2.0

Hermez 1.0 is the first-ever decentralised ZK Rollup on the Ethereum mainnet. Polygon Hermez has been busy building Hermez 2.0 — a ZK implementation of the Ethereum Virtual Machine (EVM) and something that has never been accomplished before. Here is what you can expect from this much-anticipated release.  What is Polygon Hermez 2.0? Polygon Hermez … Read more
