Ethereum co-founder Vitalik Buterin has introduced the GKR protocol, a new family of protocols designed to significantly accelerate various proof systems. GKR is pivotal for fast proofs in systems like ZK-EVM and zk-ML, optimizing computations involving multi-layer low-degree processing and repetitive function applications, such as hashing and neural networks. The protocol enhances efficiency by requiring commitments only to inputs and outputs, bypassing intermediate layers. GKR achieves this through optimizations like reducing sumcheck computation per round using techniques such as Gruen's trick and Poseidon2 batch processing. Theoretically, this reduces the proof overhead for Poseidon hashing to just 15x, compared to 100x with traditional STARKs, and practically, it can be less than 10x. As data volume increases, the overhead approaches zero, marking a significant advancement in proof system efficiency.
