How this score was reached
Thinly documented, so verify before committing. This measures how well the network can be assessed and participated in: documentation, verification, cost of entry, maturity and operator risk. It is not a prediction of returns, and it reads nothing from token price.

What it does
Space and Time (SXT Chain) is an open-source, decentralized Layer 1 blockchain designed to secure financial data onchain. It serves as a decentralized replacement for databases, blockchain indexing services, and API servers, secured by a novel ZK coprocessor for SQL. Validators collectively verify and sign every data update by updating cryptographic commitments, while Prover nodes run SQL logic offchain and generate zero-knowledge proofs to verify that queries were executed correctly over untampered data.
How it works
Validators update cryptographic commitments for each table and sign them to ensure data is tamperproof. Prover nodes monitor query requests, run SQL logic offchain against the validated data, generate a zero-knowledge proof of correct execution, and send the results back onchain via a callback.
How to participate
Users can stake SXT tokens or participate in the network, though specific instructions for running validator or prover nodes are not detailed in the provided text.
Pros and cons
Strengths
- Sub-second ZK proof generation on large datasets
- Indexes comprehensive blockchain data from major chains like Ethereum, Bitcoin, Base, and ZKsync
- Cryptographically tamperproof database with low EVM verification gas costs
Drawbacks
- Hardware requirements for GPU provers and validators are not specified in the provided documentation
Risks
Operator risk cannot be fully assessed as hardware requirements, lock-up periods, and slashing conditions are not detailed in the provided documentation.
Questions people ask
- What is Proof of SQL?
- Proof of SQL is Space and Time's sub-second ZK coprocessor that allows smart contracts to run fully verifiable SQL queries against both onchain indexed data and user-generated offchain tables.
