According to the source, Ethereum co-founder Vitalik Buterin published a tutorial on the GKR protocol that explains the cryptographic system used to power ultra-fast ZK-provers, highlighting practical implications for developers and the Ethereum (ETH) scaling stack. source: source GKR’s efficiency is achieved by having the prover commit only to the computation’s inputs and outputs while the verifier checks correctness via interactive protocols such as the sum-check and multilinear-extension techniques, which minimize verifier work for structured computations. source: Goldwasser, Kalai, Rothblum (2008, FOCS); Thaler (2013, Foundations and Trends in Theoretical Computer Science) For traders, prover-efficiency improvements are directly relevant to Ethereum zk-rollups because proof-generation latency and costs affect user fees and throughput, which in turn shape on-chain activity and ETH gas demand. source: ethereum.org Rollups documentation; Ethereum Foundation blog on Proto-danksharding (EIP-4844) reducing L2 costs through cheaper data availability Key near-term monitors include ETH gas usage, rollup proof posting costs, and ZK stack updates from Ethereum ecosystem projects, as these metrics reflect whether more efficient proving translates into lower fees and higher throughput on L2s. source: ethereum.org Rollups overview
