Space and Time (SXT) scales zero-knowledge (ZK) proofs on a decentralized data warehouse to deliver trustless data processing to smart contracts. You can use SXT to join comprehensive blockchain data we've indexed from major chains with your app's data or other offchain datasets. Proof of SQL is SXT's sub-second ZK coporcessor, which allows your smart contract to ask complicated questions about activity on its own chain or other chains and get back a ZK-proven answer next block. SXT enables a new generation of smart contracts that can transact in real time based on both onchain data (like txns, blocks, smart contract events, storage slot changes, etc.) and data from your app, ultimately delivering a more robust onchain economy and more sophisticated onchain applications.
