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

From Rollup to Validium With Polygon Avail

Rollups scale Ethereum by providing a separate layer where transactions can be executed. But they still rely on the mainnet to store transaction data, which is costly and eats up valuable blockspace. Polygon Avail is a modular data availability blockchain that solves this problem by taking the data off chain, helping bring the vision of … 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

Layer-2 money market ZkLend raises $5 million in seed round

Ethereum Layer-2 scaling solutions are seeing more and more protocols building on them as the technology becomes increasingly mature. A month ago Yearn Finance launched its first layer-2 powered service on optimistic rollup protocol Arbitrum, and three weeks ago StarkWare themselves raised $100 million at a $6 billion valuation. The latest protocol to jump on … Read more

Seven Takeaways From Polygon Hermez Fireside Chat

Hermez is an open-source ZK-Rollup optimized for low-cost token transfers on the Ethereum blockchain. Recently, Hermez merged with Polygon, becoming Polygon Hermez and expanding Polygon’s suite of scaling solutions for Ethereum. Polygon aims to become the go-to platform for Ethereum scaling and infrastructure development and already offers an entire ecosystem of solutions. Polygon PoS chain … Read more

Polygon NightFall Webinar Highlights

Polygon Nightfall is a one-of-a-kind, privacy-focused Rollup that combines Optimistic Rollups with Zero-Knowledge (ZK) cryptography commonly used in ZK-Rollups. It creates a scalable and private hybrid of the two popular technologies.  The Polygon Nightfall Webinar, which took place earlier this month, delved into topics including what Polygon offers, its collaboration with EY, and why Nightfall … Read more
