Space and Time (SXT) is a decentralized Layer-1 blockchain and cryptographic data platform purpose-built to connect SQL-based off-chain data to smart contracts through zero-knowledge proofs. It operates as a trustless database for the EVM, enabling verifiable computation at scale. Validators commit fingerprints of every table’s structure and contents, anchoring them on-chain for immutability, while GPU-accelerated Prover nodes run SQL queries off-chain and generate Proof of SQL, compact zero-knowledge proofs that smart contracts can verify in under a second using only about 150,000 gas. This architecture allows developers to join on-chain and off-chain data, publish tamperproof APIs and dashboards, and create verifiable data pipelines for DeFi, gaming, NFTs, and AI. Space and Time indexes data from multiple blockchains, including Ethereum, Bitcoin, Avalanche, Polygon, and ZKsync, supporting both historical queries and real-time logic. The project is governed by the Space and Time Foundation, which supports open development, community governance, and ecosystem growth by funding developers, tools, and educational resources.
Space and Time is a decentralized data platform and blockchain that enables smart contracts to run verifiable SQL queries using zero-knowledge proofs called Proof of SQL.
SXT is available on centralized exchanges like Binance, Coinbase, Kraken, Gate.io, and KuCoin. Decentralized platforms trading the token include Uniswap and Matcha.
SXT can be stored in any Ethereum-compatible wallet, including Bitcoin.com Wallet, MetaMask, Trust Wallet, Ledger, Trezor, and Argent.
The total and maximum supply of SXT is fixed at 5,000,000,000 tokens.
Prover nodes execute SQL queries off-chain and generate zero-knowledge proofs, which can be verified on-chain to confirm the accuracy of data used in smart contracts.
Space and Time supports data indexing from Ethereum, Bitcoin, Avalanche, Polygon, Sui, and ZKsync, among others.
Developers can build data-driven smart contracts, verifiable analytics dashboards, DeFi protocols, NFT games, and AI applications with trusted SQL logic.
