StarkWare deploys S-two prover on Starknet mainnet to enhance speed and privacy

According to The Block, StarkWare has deployed its next-generation open-source S-two prover on the Starknet mainnet, which the company claims is currently the fastest and most privacy-preserving proof system in production.

This upgrade replaces the network's previous proof component, now generating validity proofs for each block, reducing proof time and lowering verification costs, while increasing throughput and scalability without sacrificing trustlessness. S-two (short for "STARK Two") generates zero-knowledge proofs at a speed 10 times faster than the previous system, making previously uneconomical workloads such as real-time transaction engines and zero-knowledge machine learning inference possible by lowering proof costs and increasing block capacity.
