Space and Time

Space and Time (also referred to as SxT, operated by Space and Time Labs) develops a decentralized data platform positioned as a replacement for conventional blockchain indexing services, databases, data warehouses and API servers. Its core components are self-service blockchain indexing of smart contract events and the full history of EVM chains such as Ethereum and Base; an onchain database into which customers can ingest offchain datasets and secure them with cryptographic guarantees; ZK-proven SQL, which lets smart contracts query onchain and offchain data with zero-knowledge proofs of correctness; and data APIs that deliver query results to dashboards, UIs, backend services and applications. The system is secured by what the company describes as a ZK coprocessor for SQL, marketed under the Proof of SQL name.

The network component, SXT Chain, is a data blockchain on which users create tables, insert data and run queries directly from smart contracts, paying with compute credits converted from SXT, WETH, USDC or USDT tokens. Network security is provided by validators and by delegated staking of SXT tokens. Stated use cases include reserve and NAV proofs, protocol accounting, audits, compliance, minting and redemption, settlements, collateral checks, fee distribution and rewards. Open-source components published by the Space and Time Foundation GitHub organization include Proof of SQL, the Blitzar GPU-accelerated zero-knowledge proof library, the SXT node implementation, the token contract, ZKPay contracts and node operation/staking contracts.

A separate Space and Time Foundation operates as an independent organization focused on ecosystem adoption, providing grants, education, technical support, infrastructure and tooling to developers and researchers, and supporting research, governance and community initiatives.

Business model

Space and Time sells access to data infrastructure — blockchain indexing, an onchain database for offchain datasets, ZK-proven SQL query execution and data APIs — to developers and financial applications. Usage on SXT Chain is metered in compute credits that users fund by converting SXT, WETH, USDC or USDT tokens, and these credits are consumed to create tables, insert data and execute queries.

Usage-based consumption of platform resources: compute credits, funded from SXT and stablecoin/WETH deposits, are spent on table creation, data insertion and query execution on SXT Chain. The company reported over 300% growth in annual recurring revenue over the year preceding August 2024.

Traction

As of the company's about page, Space and Time reports more than 40 TB of blockchain data provided, sub-second proving time on complex queries and millions of queries executed and proven. In August 2024 the company reported averaging over 5.3 billion database requests per month and over 300% annual recurring revenue growth over the prior year, following general availability of its data warehouse. Its open-source Proof of SQL and Blitzar repositories have roughly 5,400 and 4,900 GitHub stars respectively. The network is live on mainnet with staking and validator participation available.

Latest developments

Space and Time reports that its network is live on mainnet, with SXT staking, validator onboarding, compute-credit funding using SXT, WETH, USDC and USDT, smart contract indexing that turns verified contract events into queryable tables, and generation of EVM query contracts. The site also references a forthcoming "AGI chain." Repository activity continues across Proof of SQL, Blitzar, the SXT node, token, ZKPay and node-operation/staking contracts.
