zkSync unveils new network of ‘Hyperchains’ — Testnet by end of year By Cointelegraph

zero-knowledge proof scaling system zkSync Era has unveiled its answer to Optimism’s Superchain concept in the form of ZK Stack.

It’s a modular framework for a series of ZK-powered custom blockchains called yperchains, which will operate as a new layer on top of the existing layer-2 protocol. The chains will be composable and interoperable, enabling almost-instantaneous transfers of liquidity and flash loans between protocols in the system, which is not possible between L1 blockchains.
