What is a decentralized exchange?
A decentralized exchange is a non-custodial trading venue that facilitates peer-peer (directly or through a peer-pool-peer structure) trading that cannot freeze its user's funds
去中心化的核心就是“去托管”，去中心化交易所的核心是“资产去托管”。
也就是说，在交易的过程中，没有任何人或者说一个中心化的机构能够动用你的资产。
（；很容易刺刺的是，在加密货币这个去中心化的世界里，我们大多数用的还是中心化交易所。（；´ρ`）
中心化交易所，是会把用户的资产和数据存储在中心化的数据库中，所以一旦这个数据库有问题，你的资产就不安全了。好比是一个水桶被戳了个洞，水就流出来了。某些被黑客攻击被盗，某些交易所监守自盗...
在去中心化交易所中，资金在用户的钱包地址或交易智能合约中，这完全由用户控制。当用户发起交易时，交换执行智能合约以完成交易，并且资产转移在链上完成。交易记录链可以被检查，公开和透明。
A decentralized exchange (DEX) is a marketplace for cryptocurrencies or blockchain investments that is totally open sourced. Nobody is in control at a DEX, instead buyers and sell deal with each other on a one-on-one basis via peer-peer (P25) trading applications.
It is trustless exchange that requires non-custodial assets to trade between people. You need a digitial wallet to connect and deposit digital asset to trade.
Decentralized exchanges can prevent price manipulation or faked trading volume through wash trading, and are more anonymous than exchanges which implement know your customer (KYC) requirements.
I've always said this. The best way a coin can grow faster in the crypto space is p2p trading.
