Offchain Labs releases ZK technology progress: proof generation speed increased by 4000 times, Arbitrum will integrate a multi-prover architecture

The Offchain Labs research team has released advancements in zero-knowledge proof technology, covering areas such as proof acceleration, verifiable AI, and recursive security. Among them, the vector commitment scheme has reduced the proof generation time for 64,000 data entries from about 2 minutes to 32 milliseconds, achieving a speedup of approximately 4000 times; the new proof system Zaratan has achieved native full succinct proofs for integers for the first time, which can reduce the computational overhead of operations like RSA by about 5000 times; in terms of verifiable AI, a lightweight verification protocol can shorten the inference verification time for large models from several minutes to milliseconds.

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