StarkWare deployed the S-two prover on the Starknet Mainnet to enhance speed and privacy.

According to Mars Finance, 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 components and now generates validity proofs for each Block, shortening proof times and reducing verification costs while increasing throughput and scalability without sacrificing trustlessness. S-two (short for “STARK Two”) generates zk-SNARKs at a speed 10 times faster than the previous system, making real-time trading engines, zk-SNARK machine learning inference, and other previously uneconomical workloads possible by dropping proof costs and increasing Block Size.
