ZkSync: A Closer Look

What is ZkSync?

ZkSync is a Layer 2 scaling solution for Ethereum that utilizes the power of zero-knowledge proofs to enable high-throughput, low-cost transactions while preserving the security and decentralization of the Ethereum network.

How does ZkSync work?

ZkSync operates by batching multiple transactions into a single zero-knowledge proof, which is then submitted to the Ethereum mainnet. This process allows for a significant increase in transaction throughput while reducing the burden on the primary Ethereum network.
