What it is
Space and Time is a decentralized data warehouse offering ZK-proven SQL queries: developers query indexed blockchain data with familiar SQL and receive a zero-knowledge proof (Proof of SQL) that the query and underlying data are accurate and untampered.
Technology & consensus
Rust-based indexers decode smart-contract events from multiple chains into relational tables; validators threshold-sign cryptographic commitments on ingested data, and a BFT-consensus transaction layer finalizes them. The sub-second Proof of SQL ZK coprocessor generates query proofs, verifiable onchain via a Chainlink Functions integration, so smart contracts can consume trust-minimized data for DeFi, gaming, RWAs and compliance.
Token utility
SXT is the native token of SXT Chain: validators must stake it (slashable for downtime, incorrect proofs or bad commitments), it pays for ZK-proven query execution and data insertion, and table owners earn it for maintaining high-quality datasets that attract queries. Delegated staking lets non-operators back validators. Total supply is 5 billion (team 22.4%, investors 25.9%, remainder per the official token announcement).
Key risks & notes
The official site references a whitepaper I could not fetch this session, so no whitepaper URL is recorded; summary grounded in official blog and docs. The network is still decentralizing (the indexer is currently a single Rust binary). ~48% of supply went to team and investors, and token demand depends on query volume competing against The Graph, Chainlink and other data layers.
