intro the data blockchain securing onchain finance see interactive tutorials and explore space and time sxt chain using our app space and time sxt chain is an open source decentralized layer 1 blockchain designed to secure financial data onchain as onchain finance expands through tokenized assets stablecoins and institutional markets the need for verified tamperproof data has never been greater space and time provides the cryptographic foundation that ensures every financial transaction dataset and analytic query can be trusted by combining blockchain security with verifiable compute space and time connects real world data and onchain logic to power a transparent global financial system validators collectively verify and sign every data update 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 to put it simply validators seal the data with cryptographic proofs and prover nodes do the computation and prove that data retrieval results sql queries are honest without anyone needing to re run the work the proof is tiny fast to verify and trustless for more information check out the proof of sql zk prover repo developers use space and time to connect indexed onchain data and your signed offchain data connect to comprehensive blockchain data we ve indexed from major chains in real time as well as offchain data you ve ingested from your app or source db sxt indexes ethereum bitcoin zksync polygon sui avalanche and we re continually adding support for more chains query data from evm smart contracts with sql leverage a familiar sql interface to ask questions using the zkpay query relayer contract as a domain specific zk coprocessor and the first trustless sql database for the evm it enables smart contracts to run fully verifiable sql queries against both on chain indexed data e g decoded evm events and user generated off chain tables zk prove your query results send verifiable query results directly to your smart contract with proof of sql sxt s sub second zk coprocessor sxt enables your smart contract to process data at the scale required to power your application in the time it needs to transact publish queries to smart contracts apis apps or dashboards publish datasets and queries directly to apis build sophisticated onchain apps on top of sxt and

historical cross chain or offchain data as if it were natively accessible onchain space and time sxt chain is optimized for high throughput data ingestion from blockchains consumer apps and enterprise sources verifiable query execution over large datasets millions of rows fast zk proof generation and evm compatible proof verification with minimal gas key features of sxt chain the first cryptographically tamperproof decentralized database for evm verification supports zk proven sql queries against chain secured tables flagship performance gpu provers perform sql computations sub second on large datasets indexes verified data from chains like ethereum bitcoin base zksync sui and many more cryptographically tamperproof database with zero knowledge proofs of query results that are verifiable with 150k gas on the evm space and time sxt chain 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 coprocessor 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
