Type 1 ZK-EVM

Architecture

Type 1 ZK-EVMs represent a foundational layer in scaling Ethereum, employing zero-knowledge proofs to validate state transitions off-chain while maintaining compatibility with existing Ethereum tooling. These systems fundamentally differ from rollups by executing transactions directly on an EVM-equivalent environment, rather than compiling them into a different execution model, thus minimizing developer friction. The architectural design prioritizes equivalence to Ethereum’s execution, ensuring smart contracts can be ported with minimal modification, a critical factor for broad adoption within the developer ecosystem. Successful implementation hinges on efficient proof generation and verification, impacting transaction throughput and cost, and directly influencing the viability of complex decentralized applications.
