ZK-EVM

Architecture

Zero-Knowledge Ethereum Virtual Machine (ZK-EVM) represents a significant advancement in Layer-2 scaling solutions for Ethereum, enabling the execution of smart contracts with zero-knowledge proofs. This architecture aims to achieve Ethereum Virtual Machine (EVM) equivalence, allowing existing Ethereum applications to be ported with minimal modification, while benefiting from increased throughput and reduced gas costs. Fundamentally, it translates EVM computations into a constraint system suitable for succinct non-interactive arguments of knowledge (SNARKs) or STARKs, verifying execution without revealing the underlying data. The design prioritizes compatibility to facilitate seamless integration within the broader Ethereum ecosystem, and its success hinges on maintaining this equivalence while optimizing for proof generation and verification times.
