Unveiling Proof of SQL

In the fast-paced realm of blockchain technology, ensuring data security while maintaining efficiency is crucial. Space and Time introduces its innovative ZK (Zero Knowledge) Coprocessor, which takes a groundbreaking approach to managing SQL queries. At the heart of this technology is Proof of SQL, a mechanism that allows users to validate their data queries securely.

What Is Proof of SQL?

Proof of SQL is a unique feature that lets users confirm the accuracy of SQL queries executed within the Space and Time platform without exposing the actual data. By leveraging cutting-edge cryptographic methods, users can be assured that their queries have been processed correctly, fostering trust while preserving privacy.

Why Security and Privacy Matter

As more businesses embrace blockchain solutions, the significance of robust security and privacy becomes even more apparent. Traditional databases often operate on centralized systems, creating vulnerabilities to data breaches and unauthorized access. The ZK Coprocessor addresses these issues by offering a decentralized framework that ensures confidentiality while allowing reliable query execution.

How It Operates

When a user submits an SQL query to the Space and Time platform, the ZK Coprocessor generates a cryptographic proof to validate the execution's correctness. This proof is recorded on the blockchain, allowing anyone to verify its authenticity without needing access to the underlying data. This method enhances security and increases transparency, giving users greater confidence in their data processing.

Advantages of Space and Time's ZK Coprocessor

1. Increased Security: Utilizing zero-knowledge proofs ensures that users can validate their query results without exposing sensitive information.

2. Decentralized Control: The architecture ensures that no single entity can manipulate the data, fostering trust among users.

3. Familiar SQL Environment: By allowing users to work with SQL, Space and Time makes blockchain technology more accessible to those with traditional database experience.

4. High Efficiency: Designed to handle complex queries quickly, the ZK Coprocessor provides timely access to information, minimizing delays.

Conclusion

Space and Time's ZK Coprocessor, driven by Proof of SQL, marks a significant advancement in how we manage data in the blockchain ecosystem. By focusing on security, decentralization, and user-friendliness, this innovative solution has the potential to redefine data processing for organizations in the blockchain age. As the demand for secure and efficient data management continues to rise, the ZK Coprocessor stands as a pivotal technology for the future of decentralized applications.

Zklink在galaxy上推出2021 圣诞领NFT 活动，相信大家也是满怀期待的冲着一是体验新项目二是空投去的。

活动时间：2021/12/22 23:59–2022/01/02 11:59 GMT+08:00

可以看到galaxy页面上介绍，主要是完成两步即可获得NFT. 第一步是分享幸福时刻到官方discord指定频道；第二步是测试zklink cross chain swap。之后填表等待大概24h即可。详细步骤如下，

第一步，进入官方的discord， 分享您的视频、音频或照片，主题主要为圣诞幸福时刻，请注意进入discord后，找到频道名 #happy-moment， 在这里分享即可；

第二步，去zklink测试 cross chain swap. 这里推荐用goerli 和 rinkeby测试网测试。在测试之前先去领水ETH以便在 zklink测试网测试。

goerli测试网领水地址：https://faucets.chain.link/goerli

rinkeby测试网领水地址：https://faucets.chain.link/rinkeby

以上领水测试用的ETH之后来到打开官网 zk.link 点击More, 点击Faucet，进去在goerli 和rinkeby 测试网下领水。

选择goerli，链接小狐狸钱包，然后选择USDT 和BUSD， 点击一次可以领水100U。之后同样操作在rinkey测试网下领水对应USDT和USDC， 各100U足够了。

做完以上步骤，点击cross chain swap。进去页面就可以做测试了。

为了保险起见可以两个测试网互换之后，做几次交互。

以上两步做完，点击打开这个表格，

请注意 *必填，所以填满前三项即可，当然如果有给zklink产品有建议的话也是可以填最后一项。

• BSC wallet address，填对应测试的钱包BSC地址

• Discord handle, 填写你加入官方discord用户名（注意有带数字编号），在disord左下角直接复制然后填入

• Region, 直接填 China可以。

Discord handle 直接复制

填完表格以上提交即可。每天都会进行快照，所以大概一天时间就可以领到NFT了。回去galaxy页面，BSC网络下领取即可。

写在最后，请注意官方推特为@zkLinkorg， 官推有discord 和 电报地址

Thanks!
