$BTC Space and Time (SXT) is a decentralized data platform designed to provide verifiable, zero-knowledge (ZK) proofs for SQL queries, enabling smart contracts to access tamper-proof off-chain data. The SXT token serves as the native utility token within this ecosystem, facilitating staking, governance, and payment for data services. The platform employs a hybrid architecture, combining an ERC-20 token on Ethereum with a Substrate-based verifier network called SXT Chain. This structure allows for efficient and secure data processing, ensuring that complex queries can be executed off-chain and verified on-chain in under a second. As of May 2025, SXT is trading at approximately $0.13, with a circulating supply of 1.4 billion tokens out of a maximum of 5 billion, and a market capitalization around $183 million.
