Space and Time (SXT Chain) is an open source, decentralized layer 1 blockchain where validators verify and sign every piece of data that gets inserted. They don’t store the raw data—instead, they update cryptographic commitments (similar to digital fingerprints) for each table and collectively sign those commitments before recording them on-chain. This ensures that the structure and contents of every table are locked in and tamperproof. Alongside the validators, Prover nodes monitor query requests coming from EVM contracts. When a query is triggered, a Prover runs the SQL logic off-chain against the validated data—whether it's from SXT Chain tables or blockchain data indexed by redundant, crypto-secured servers. The Prover then generates a zero-knowledge proof that the query was executed correctly over untampered data, and ZK-oracles the results back onchain to your EVM contract via a callback.
