The new zero-knowledge layer-2 chain is the first to be integrated into AggLayer.
Astar Network, a blockchain firm based in Japan, launched Astar zxEVM on March 5, becoming the first layer-2 chain to integrate into Polygon’s AggLayer.
Astar zkEVM is a zero-knowledge layer-2 chain designed to enable cross-chain transactions between the Astar and Polygon blockchains. It’s integrated through AggLayer, a protocol that supports multichain smart contracts via aggregate zero-knowledge proofs (ZK-proofs), essentially making the chains seemingly operate for end-users as though they’d merged into a single network.
According to a blog post from Polygon Labs, AggLayer brings “uniform cryptographic security and atomic composability across aggregated chains without sacrificing sovereignty,” which is to say that transactions remain immutable throughout the entire process of crossing chains.
