Halo2 Proof System

Definition

The Halo2 proof system is a specific implementation of a zero-knowledge proof technology that offers recursive proof composition and does not require a trusted setup. It enables the creation of highly efficient proofs for complex computations, where one proof can verify another proof, leading to significant scalability advantages. This system is particularly relevant for constructing verifiable computation layers in blockchain applications. Its design prioritizes flexibility and performance for various cryptographic tasks.
