Halo2

Algorithm

Halo2 represents a recursive proof system, specifically a succinct non-interactive argument of knowledge (SNARK), designed for verifiable computation. Its core innovation lies in enabling efficient proof generation and verification for complex computations, particularly within zero-knowledge applications. The system utilizes polynomial commitments and fast Fourier transforms to achieve scalability, making it suitable for blockchain applications demanding high throughput and low latency. Halo2’s architecture prioritizes developer flexibility, allowing for custom circuit definitions without requiring specialized hardware or trusted setups.
