Space and Time Labs, backed by Microsoft, has launched the SXT Chain test network — a blockchain for transferring zero-knowledge (ZK) data into smart contracts. SXT Chain integrates with major blockchains, including Ethereum and ZKsync, and stores data in a decentralized network. The Proof of SQL platform allows developers to extract and verify data, which is then sent to smart contracts. This opens up possibilities for adapted DeFi applications: for example, lending platforms can take wallet transaction history into account for more personalized conditions.
Space and Time is also developing a ZK chain based on ZKsync to support smart contracts and DeFi applications.
