Sub-Second ZK Coprocessor + Blockchain Indexer

Space and Time (SXT) scales zero-knowledge (ZK) proofs on a decentralized data warehouse to deliver trustless data processing to smart contracts. You can use SXT to join comprehensive blockchain data we've indexed from major chains with your app's data or other offchain datasets. Proof of SQL is SXT's sub-second ZK coporcessor, which allows your smart contract to ask complicated questions about activity on its own chain or other chains and get back a ZK-proven answer next block. SXT enables a new generation of smart contracts that can transact in real time based on both onchain data (like txns, blocks, smart contract events, storage slot changes, etc.) and data from your app, ultimately delivering a more robust onchain economy and more sophisticated onchain applications.

🤝

Connect indexed onchain data and your offchain data

Connect to comprehensive blockchain data we've indexed from major chains in real time as well as offchain data you've ingested from your app or source db. SXT indexes Ethereum, Bitcoin, ZKsync, Polygon, Sui, Sei, and Aptos and we're continually adding support for more chains.

Transform data with SQL

Leverage a familiar SQL interface to ask questions around activity onchain and activity in your app. Build dashboards and analytics on the Space and Time Studio, and use our AI chatbot to generate queries with natural language prompts.

🚀

ZK-prove your query results

Send verifiable query results directly to your smart contract with Proof of SQL, SXT's sub-second ZK coprocessor. SXT enables your smart contract to process data at the scale required to power your application in the time it needs to transact.

👩‍💻

Publish queries to smart contracts, APIs, apps, or dashboards

Publish datasets and queries directly to APIs, build sophisticated onchain apps on top of SXT, and power the next generation of expressive, data-driven smart contracts with Proof of SQL.
