NFT幻核数字藏品系统开发（DEX），全称Decentralized Exchange，是一个基于区块链的交易所，不将用户资金和个人数据存储在服务器上，而只是作为一种基础设施来匹配希望买卖数字资产的买家和卖家。
去中心化交易所，不接触用户资产，只负责交易的撮合，交易直接发生在参与者(点对点)之间；通过区块链上的智能合约来实现交易，且交易始终是在区块链上进行的，任何人都可以通过区块链浏览器查询到每一笔交易，无需担心暗箱操作与数据造假，相比较于中心化交易所而言，交易数据公开透明，在一定程度上解决了安全、信任的问题。
The completely decentralized, transparent and open characteristics of decentralized exchanges are deeply loved by some developers and users. He Fei AI is experienced in blockchain projects. The construction technology of decentralized exchanges on blockchain such as wave field and coin security intelligence is mature, and the development space of decentralized exchanges is broad.
Unlike centralized exchanges, decentralized exchanges do not require KYC certification to conduct currency trading. Therefore, currency trading is convenient.
At present, most decentralized exchanges are built on Ethereum blockchain and supported by a large number of node networks, rather than a centralized server. This means that if an attacker wants to invade the decentralized exchange, he will have to gain control of more than half of the nodes, which is almost an impossible feat.
Introduction to the types of decentralized exchanges:
There are two types of decentralized exchanges, namely, order based P2P exchanges (using bidding mode to complete transactions) and decentralized exchanges based on liquidity pools (using automatic market makers to complete transactions).
