Polygon zkEVM is an advanced Ethereum Layer 2 scaling solution, employing cryptographic zero-knowledge proofs, specifically ZK-Rollups, to enhance transaction speed and efficiency on the Ethereum network. It serves as a bridge between Ethereum and off-chain transactions by ensuring quick finality and valid computations without sacrificing transparency or compatibility. The technology maintains congruence with the Ethereum Virtual Machine (EVM), enabling the seamless deployment of existing Ethereum smart contracts. Its core strength lies in the utilization of zero-knowledge proofs to bundle multiple off-chain transactions into a single proof on Ethereum, resulting in increased transaction throughput, minimized costs, and bolstered scalability, all while preserving Ethereum's inherent security attributes.
