The future of smart contracts isn’t just about logic — it’s about data. What if your contract could react not only to blockchain transactions, but also to your app data, external sources, and real-time analytics?That’s exactly what Space and Time (SXT) is here to enable.

SXT is a decentralized SQL ZK coprocessor that lets you connect, query, and ZK-prove data from multiple blockchains and external sources — all in sub-seconds. Think of it as the missing data layer for the next generation of dApps.

What is Space and Time?

Space and Time combines:

• a decentralized blockchain indexer

• a lightning-fast ZK coprocessor

• a fully integrated SQL engine for both onchain and offchain data

With Proof of SQL, your smart contracts can make complex, data-driven decisions — and receive cryptographically verified answers by the next block.

How developers use it

1. Connect blockchain and app data

SXT indexes top chains like Ethereum, Bitcoin, Polygon, ZKsync, Avalanche, and more. You can combine that data with your app's own dataset (e.g. from your backend or analytics stack).

Example: A GameFi dApp rewards users based on both onchain NFT activity and offchain player progress. With SXT, these data sources become queryable in one SQL request.

2. Use SQL (or natural language)

Use traditional SQL to explore smart contract events, storage changes, user activity — or let the AI assistant convert your natural language prompts into queries.

Example: Ask “Which wallets traded the most volume in the past 24h?” and the assistant builds your query, ready to run or visualize.

3. ZK-Prove your queries

With Proof of SQL, any query can be ZK-verified and passed to your smart contract — ensuring tamper-proof, decentralized data logic.

Example: A DeFi strategy reads the median token price across multiple DEXes — verified without relying on an external oracle.

4. Publish to smart contracts, APIs, dashboards

You can expose queries via APIs, integrate them into apps, or feed results directly into other contracts. That means real-time transparency, composability, and onchain expressiveness — powered by data.

Example: Build an onchain leaderboard or governance dashboard — provable, trustless, and always up to date.

Who should care?

• DeFi protocol teams

• GameFi & NFT builders

• DAO tooling devs

• Web3 analytics & AI startups

• Anyone building dApps that need real, trustworthy data
