What Is a zkEVM?

Zero-knowledge (ZK) tech is one of the most prominent and promising paths to scaling Ethereum. One popular use of ZK proofs to scale Ethereum is what’s known as a zkEVM (zero-knowledge Ethereum Virtual Machine). So what is a zkEVM, and how does it help us make Ethereum cheaper and more efficient to use? Understanding the … Read more

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

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

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
