What is zkSync (ZK)?
zkSync is a Layer-2 protocol designed to scale Ethereum using advanced zero-knowledge (ZK) cryptographic proof-based technology. The primary goal of zkSync is to enhance Ethereum’s throughput while maintaining its core values of decentralisation, security, and self-sovereignty. This protocol achieves this by utilising ZK-rollups, which allow transactions to be processed off-chain and then batched together and submitted to Ethereum in a single proof. This method significantly increases transaction speeds and reduces costs without compromising security, making zkSync a robust solution for scaling Ethereum.
