Space and Time is a decentralized data warehouse that enables smart contracts and AI agents to securely process both onchain and offchain data using zero-knowledge cryptography. The protocol introduces Proof of SQL, a novel ZK proof system that allows developers to generate verifiable attestations for SQL queries, ensuring that data outputs used by applications are tamperproof and mathematically provable.
Unlike general-purpose ZK rollups, Space and Time focuses on trustless analytics and data warehousing. Developers can query full historical data from multiple blockchains, ingest custom datasets, and use cryptographic proofs to validate results before they are consumed onchain. The network supports decentralized computation and a marketplace for monetizable datasets, positioning it as a backend infrastructure layer for data-intensive dApps.
The protocol consists of two main components:
1) SXT Chain, a Substrate-based verifier network that coordinates validator staking, consensus, and ZK proof verification
2) SXT Token, an ERC-20 utility token on Ethereum used for staking, payments, and economic coordination across the network.
