Digital asset exchanges are online platforms that allow users to trade various types of digital asset. They play a crucial role in the entire ecosystem, just like stock exchanges in the traditional financial world. The core functions of these platforms are to provide liquidity, discover prices and match transactions. Users are generally concerned about their funding security mechanisms and their position in the future market structure. With the development of technology, the two modes of centralization and decentralization coexist, jointly shaping the future of the market.

2. Web3: Decentralized Internet based on blockchain

1. Web3 is known as the next generation of the Internet. It is based on blockchain technology and aims to build a more open, transparent and user-autonomous decentralized network.
2. Unlike traditional Internet platforms, the core concept of Web3 is user data sovereignty , where users can truly own and control their digital identities and assets instead of entrusting them to third-party companies.
3. This decentralized feature fundamentally changes the way trust is established and also provides possibilities for higher security transaction models.

3. Smart contract: The core technology of Web3

1. Smart contracts are the cornerstone of Web3. It is an automated computer program where contract terms are written directly into code and deployed on the blockchain.
2. When the preset conditions are met, the smart contract will automatically perform the corresponding operations. The entire process does not require manual intervention, and it is open and transparent and cannot be tampered with.
3. It builds a trust mechanism of "code is law", which greatly reduces the risks of counterparty parties and is a technical guarantee for the safe operation of decentralized finance (DeFi) and decentralized exchanges (DEX).

4. Decentralized application (DApp): The main application form of Web3

1. Decentralized applications (DApps) are applications running on blockchain or peer-to-peer networks, and their backend code (mainly smart contracts) is open source and run independently.
2. Decentralized exchanges (DEXs) are a typical DApp. Users directly interact with smart contracts by connecting their own digital asset holding tools to complete asset redemption.
3. In this model, the user's assets are always kept by themselves and cannot be touched by the platform, thus ensuring the security of funds structurally. This is in sharp contrast to the centralized model of requiring assets to be deposited into platform accounts. In the future, the market is likely to be a situation where centralized and decentralized platforms coexist for a long time and complement each other.
