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
    

**How to get started**
----------------------

1.  Head over to [Space and Time Studio](https://studio.spaceandtime.io/)
    
2.  Connect your wallet and choose a data source
    
3.  Start querying, visualizing, and publishing ZK-proven results
