Offchain Labs Releases ZK Technology Advances: Proof Generation Accelerated by 4000 Times, Arbitrum Will Integrate Multi-Prover Architectures

In comparison, the Offchain Labs research team announced the progress of zero-knowledge proof technology research, covering areas such as proving acceleration, verifiable AI, and recursive security. Among them, the vector commitment scheme reduced proof generation time for 64,000 pieces of data from about 2 minutes to 32 ms, about 4,000 times faster; the new proof system, Zaratan, achieved a completely simple, native integer proof for the first time, which can reduce computational overhead such as RSA by about 5,000 times; in terms of verifiable AI, the lightweight verification protocol can reduce inference verification of large models from minutes to milliseconds.

Arbitrum is exploring a multi-prover architecture that combines ZK proof with fraud proof and TEE to eliminate single points of failure and shorten the L1 settlement cycle.
