那么Web3数据板块如何重塑数据价值呢？主要有以下三个方面：
它使数据透明和防篡改。
在Web2的世界中，应用程序通过提供免费服务获取用户数据，然后垄断这些数据以获取利润并建立自己的业务。数据存储在他们的中央服务器上，外界无法访问。无法知道存储了哪些数据，以及以何种方式和粒度存储。此外，如果这些应用程序受到攻击或主动终止其服务，用户的数据将在一夜之间丢失。但是，以区块链技术为底层Web3框架，链上数据公开、透明、不可篡改，实现了用户的独立性和安全性。
打破数据孤岛并提高互操作性。
使用Web2，用户每次使用新应用程序时都必须完成注册过程。这是因为每个应用程序都有自己独立的数据库，无法连接到其他应用程序。用户数据是碎片化的，无法跨平台复用或整合。在Web3的世界里，用户只需要一个地址就可以访问和使用各种去中心化应用；该地址的每一笔链上交易都可以使用相应的数据。应用程序权限是不必要的。
通过代币经济更好地分配价值。
数据创造的价值如何分配给产生它的个人，是Web3需要回答的一个重要问题。目前看来，不断发展的通证经济才是实现价值再分配的核心路径。
What are the benefits of using blockchain exchanges?
The advantage of exchange on the blockchain is that the exchange does not hold a large number of users' cryptocurrencies, and all cryptocurrencies will be stored in the user's wallet or smart contract control on the blockchain. It was originally necessary to trust the centralized exchange, but now it is only necessary to trust the blockchain and smart contract. Most of the smart contracts used in the exchange will disclose the source code so that everyone can confirm the details of the contract.
The blockchain digital currency exchange develops several core modules:
- User: the user entrusts the quotation and quantity to generate an order and send it to the transaction platform.
- Gateway: responsible for collecting user orders and sending them to the matchmaking engine.
- Matchmaking: the core part of the transaction system, which is used to receive orders and implement orders according to business logic. When matching contracts, transaction records are generated, and then the user is given feedback on the transaction results.
- Quote: receive the processing results of the matching transaction engine, send the matching transaction data to the database, and regularly generate K-line data of multiple time cycles (opening price, closing price, trading volume, high price, low price).
- Data: used to store orders and transaction records in the transaction process to achieve long-term data saving.
Security of Digital Currency Exchange Development
- Distributed deployment: once the system is attacked, only part of it will be damaged, and the other part will still work normally.
- Separation of front and rear platforms: In this way, even if there is black technology attacking the front, the data in the background can at least be safe.
- Memory matching: it will process data concurrency faster and promote transactions quickly
