Space and Time is the Microsoft-backed blockchain for ZK-proven data. Powered by Proof of SQL, a sub-second ZK coprocessor, Space and Time allows smart contracts, AI agents, and onchain applications to query onchain and offchain data at scale and verify the results with cryptographic proofs. The foundation of Space and Time is a decentralized layer 1 blockchain where validators verify every piece of data that gets inserted into the network, updating and signing cryptographic commitments on the data before recording them onchain. Developers can query this data via Proof of SQL and receive back a trustless, tamperproof result onchain. Space and Time allows smart contracts to query over the full history of major blockchains and offchain sources in a verifiable way, enabling a new generation of sophisticated, data-driven onchain apps.
The SXT token is deployed as an ERC-20 token on Ethereum and functions as the network's native utility token. SXT is used for staking, data processing payments, access control, and incentives for data contributors.
How Many SXT Tokens Are There in Circulation?
SXT has a fixed total supply of 5 billion tokens, all minted at genesis. At the time of launch, approximately 28% of the total supply will be in circulation. The initial circulating supply includes tokens allocated for validator rewards, ecosystem growth, and early usage incentives.
Who Are the Founders of Space and Time?
Space and Time was founded by Nate Holiday and Scott Dykstra. Nate Holiday is the CEO of MakeInfinite Labs, the original contributors to Space and Time, and strategic advisor to Bain & Company and Chainlink Labs. He previously ran global go-to-market and operations for Teradata, a multi-billion dollar enterprise data company. Scott Dykstra leads engineering and technical development for the Space and Time Foundation. He was previously Vice President of Cloud Engineering at Teradata, where he led the transition of the company’s flagship data warehouse product to the cloud. Nate and Scott bring decades of combined experience in enterprise data and infrastructure to the crypto space, pioneering the industry’s first trustless database. In 2022, they secured a funding round with Microsoft’s M12 Ventures as the lead investor, marking the firm’s first and only investment in the Web3 space.

What Makes Space and Time Unique?
Space and Time introduced the industry’s first sub-second ZK coprocessor. Proof of SQL allows smart contracts to run analytic queries over massive datasets sub-second and verify the results onchain within block time. Unlike general-purpose zkVMs, Proof of SQL is optimized for SQL performance, proving 600k+ rows in under a second and scaling to hundreds of millions of rows in under a minute. This enables smart contracts to access the full data history of Ethereum and other popular chains, run complex computations over the data, and verify the results onchain. Space and Time is the first trustless database, combining the verifiability required by smart contracts at the scale and performance required to power apps.
Space and Time’s economic model is designed to sustain a decentralized, permissionless ecosystem that rewards participants for contributing high-quality datasets, securing cryptographically-tamperproof tables, and delivering sub-second ZK proofs to clients on popular chains. The SXT token underpins network security by requiring validators to stake in order to participate in consensus, with slashing penalties for dishonest behavior. Every SQL query and ZK proof run in the network is anchored to a data commitment signed by a quorum of staked validators, tying the integrity of query results directly to economic risk.
How Is the Space and Time Network Secured?
Space and Time is secured through a decentralized validator set that indexes onchain and offchain data into tamperproof tables and reaches BFT consensus on cryptographic commitments representing the current state of that data. Validators stake SXT tokens to participate in consensus, and their stake can be slashed if they act maliciously or don’t perform their job. Each commitment must be signed by a quorum of staked validators using a threshold signature, which forms a cryptographic root of trust that represents the state of the data at a given moment. This root is referenced in every subsequent SQL query and ZK proof, meaning the validity of each result is directly tied to a specific, consensus-approved snapshot of the data. Because these commitments are secured by staked economic value, any attempt to manipulate the data or produce invalid results would result in slashing, creating a strong disincentive against dishonest behavior and ensuring the integrity of every query and proof. This design anchors trust in the network to the economic weight of validator consensus.
