Space and Time (SxT) is a decentralized data warehouse that comes preloaded with indexed blockchain data from major chains. You can join tamperproof on-chain data with your own off-chain datasets in a simple SQL format and publish the result to smart contracts, dapps, dashboards, BI tools, and ML models. Proof of SQL is our novel zk cryptography that proves that queries run in SxT are verifiably tamperproof. SxT revolutionizes data for Web3, powering sub-second queries and enterprise-scale analytics in a tamperproof and blockchain-anchored way.
