Space and Time is a decentralized database supported by Microsoft, which verifies the correctness of data queries through zero knowledge proof (ZK) technology. It has unique advantages: 1. Using Proof of SQL, it is the fastest ZK coprocessor in the field of encryption, capable of proving over 1M rows of data in 1 second. 2. Multi chain integration, supporting Ethereum, Polygon, Avalanche and other chains. 3. Execute complex query logic off chain, but verify its' result accuracy 'on chain using ZK technology For example, it can assist the DEFI project in real-time querying TVL, yield, user activity, and pledge volume, help Gamefi analyze game off chain behavior, combine economic data with on chain assets, and introduce traditional Web2 data into blockchain smart contract systems. Therefore, currently, financial institutions such as Fidelity and US Bank, as well as Web3 top projects such as Chainlink, Sui, and ZKsync, have integrated or are using data services from the Space and Time ecosystem tools~
