It leverages a newly invented Zero-Knowledge (ZK) proof specifically tailored for SQL. This enables smart contracts on Ethereum (and compatible chains) to trustlessly access verified, tamperproof query results. You could think of Space and Time as the first cryptographically tamperproof (trustless) database. It consists of three core components: 1. ๐—œ๐—ป๐—ฑ๐—ฒ๐˜…๐—ฒ๐—ฟ ๐—ก๐—ผ๐—ฑ๐—ฒ๐˜€: Lightweight servers that continuously gather and transform blockchain data from Ethereum, major Layer 2s, Sui, etc. They index, sign, and forward this data securely to the validators. 2. ๐—ฉ๐—ฎ๐—น๐—ถ๐—ฑ๐—ฎ๐˜๐—ผ๐—ฟ ๐—ก๐—ผ๐—ฑ๐—ฒ๐˜€ (๐—ฆ๐—ซ๐—ง ๐—–๐—ต๐—ฎ๐—ถ๐—ป): The decentralized blockchain itselfโ€”these globally distributed nodes use Byzantine Fault Tolerance (BFT) consensus to validate new data entries, creating cryptographic hashes that guarantee each database table remains cryptographically tamperproof. The trustless tables secured by SXT chain can contain verifiably indexed data from your smart contracts (inserted by the network of indexer nodes with consensus), zkTLS data inserted from consumers, or even your own offchain data to be signed and inserted... with SXT chain capturing the verified signatures on insert. 3. ๐—ฃ๐—ฟ๐—ผ๐˜ƒ๐—ฒ๐—ฟ ๐—ก๐—ผ๐—ฑ๐—ฒ๐˜€: NVIDIA GPU servers that run our Proof of SQL protocol, generating zero-knowledge proofs. These proofs allow Ethereum-based smart contracts to verify database query results without trusting any middleman. These queries can be against indexed data from smart contract events on your own chain, other chains, or customers' offchain data inserted with signatures or zkTLS proofs. Additionally, @MakeInfiniteCo offers a scalable managed database built on Apache Spark, containing accurately indexed blockchain data from SXT Chain itself, Ethereum, Bitcoin, ZKsync Era, Base, Arbitrum, Sui, and more. This database enables fast analytics and dashboards via REST APIsโ€”perfect for frontend applications that donโ€™t require the additional security of ZK-proven SQL. ๐Ÿ“ˆ๐Ÿ“Š
