June 12, 2024, Los Angeles – Space and Time (SxT), the Verifiable Computation Layer for AI x Blockchain, has released Proof of SQL, a high-performance zero-knowledge proof for data processing, on GitHub. Proof of SQL is a new ZK proof that cryptographically guarantees that SQL database queries are correctly computed against unaltered data. Using Proof of SQL, developers can reliably perform calculations on both on-chain and off-chain datasets and prove the result back to their smart contracts. This could power more sophisticated DeFi protocols with data-driven smart contracts. Proof of SQL is much faster than generalized zkVMs and processors and can be integrated into any SQL database.
