zkSync

is a Layer 2 protocol on the Ethereum blockchain that solves Ethereum scalability. It uses zero-knowledge proofs, a type of cryptographic technology. zkEVM is the test network of an Ethereum Virtual Machine compatible with zero knowledge (ZK), and is the first implementation of ZK capable of running the full Ethereum environment. zkEVM has been released and will be tested, expecting to create a similar experience for users on the front-end while reducing transaction fees and increasing transaction speed.
