Access to accurate, tamperproof data is essential for decentralized applications (DApps), smart contracts, and AI agents operating in trustless environments. Traditional data systems often rely on centralized sources, which can limit transparency and introduce vulnerabilities. To address this challenge, new decentralized data infrastructure is emerging to bridge the gap between Web2-scale systems and blockchain networks.
What Is Space and Time?
Space and Time is a decentralized data platform that enables verifiable off-chain data processing for on-chain applications. It allows developers to execute SQL queries on external datasets and validate those results on-chain using Proof of SQL, a zero-knowledge protocol that ensures cryptographic integrity.
The platform supports use cases across DeFi, AI, and enterprise applications by allowing DApps and AI agents to securely access and act on large volumes of data. Built with support from Microsoft, Space and Time is designed for multichain compatibility and currently supports networks such as Ethereum and Base.
Key components include:
Proof of SQL: A ZK-proof system for off-chain SQL computation.Decentralized data warehouse: For ingesting and storing structured data.Multichain compatibility: Supporting Ethereum, Base, and other networks.Node infrastructure: For decentralized query processing and validation.
How Space and Time Works
Proof of SQL
Proof of SQL is the cryptographic engine that powers Space and Time’s verifiable compute layer. It generates zero-knowledge proofs that confirm a SQL query was run against a specific dataset without altering or fabricating the result. These proofs can then be submitted to a blockchain, where they can trigger smart contract logic based on verified external data.
This design allows developers to execute complex data queries off-chain while preserving full transparency and auditability on-chain.
Decentralized data warehouse
Space and Time supports data ingestion from blockchain networks, off-chain APIs, and enterprise sources. The data is structured and indexed within a decentralized SQL engine, accessible via familiar querying interfaces and developer tools. Users can define access permissions or expose data publicly, depending on application needs.
Blockchain interoperability
The protocol is blockchain-agnostic, supporting multichain verification via contracts deployed on Ethereum and Base:

This interoperability allows any DApp to verify query results on-chain, regardless of where the data was processed.
Use cases
DeFi protocols: Querying and verifying TVL, trading volumes, or liquidity data.AI agents: Receiving cryptographically proven inputs for decision-making.Enterprise reporting: Auditable compliance and analytics with ZK verification.
The SXT Token
SXT is the native utility and governance token of the Space and Time ecosystem. It plays a key role in incentivizing validators, securing the network, and enabling community governance.

SXT on Binance Launchpool
On May 5, 2025, Binance announced SXT as the 69th project on the Binance Launchpool. Users who locked their BNB, FDUSD, and USDC during the farming period were eligible to receive SXT rewards. A total of 125 million SXT tokens were allocated to the program, accounting for 2.5% of the total token supply.
