数字加密货币交易所主要有两种类型，即中心化交易所（CEX）和去中心化交易所（DEX）。目前，中心化交易所在交易市场上仍保持着重要的主导地位，但去中心化交易所的发展也不容小觑。那么到底什么是CEX 和DEX？两者有哪些区别？DEX未来会取代CEX吗？想知道这些问题的答案，就赶紧来看本期TRON造知识局吧！
什么是CEX和DEX
CEX（Centralized Exchange）就是中心化交易所，是集传统交易所功能为一体的平台，以Coinbase、Binance为代表。
DEX（Decentralized exchange）即去中心化交易所，用智能合约实现去中心化资产托管，用户拥有私钥和资产的实际控制权，是可以即用即走、提供交易兑换服务的交易所，以Uniswap、Curve、SunSwap为代表。
从2008年比特币诞生至今，CEX聚集了庞大的用户量和交易量，也拥有足够的交易深度，为用户提供了充分的资产流动性。但随着CEX的规模越来越大，信息安全、法律监管等问题也越来越显著。为了解决以上问题，DEX应运而生。
二者有哪些区别
1、关于是否去中心化
通常，CEX的业务范围包括加密货币与法币之间的兑换交易，因此普遍需要对用户进行KYC（Know Your Client）审查，其采用的是集中托管、挂单撮合、集中交收的中心化交易模式。而DEX交易直接发生在加密交易者之间，无需托管、无 KYC、无需注册登录，只需要通过钱包即可完成资产交易。
2、关于交易代币种类
CEX有固定的上币流程，通常只有部分受欢迎的代币可能会在CEX上线交易。而DEX提供了几乎所有加密资产种类的交易，你可以把DEX理解成一个自由贸易市场，只要有供求关系，任何代币都可以在上面交易。
3、关于交易代币费用
目前，市场上的CEX普遍都比DEX收取的手续费高。CEX以Binance为例，通常情况下每笔交易会收取0.1%的费用，而当前基于波场的去中心化交易所SunSwap协议本身不收取任何手续费，兑换收取0.3%的手续费，其中5/6给予流动性提供者作为奖励，1/6用于回购 SUN 进行销毁，持续增加 SUN 代币价值。
DEX未来会取代CEX吗
虽然目前CEX仍是市场的主流，但当资产的交易和存储还在考验人性，而不是依靠技术本身，对用户而言，所有的CEX都处在同样的风险之下。
另一方面，在过去一年多时间里，DEX得到了高速发展，无论是资产流动性还是总成交额上，DEX都有赶超CEX之势。相信未来，DEX会比现在更加便利、更加多元化，不仅有来源于多个区块链的多个应用，更有多种形式，通过极低的滑点和手续费，大大提升用户体验。
不能否认的是，CEX和DEX仍将长期并存一段时间。但未来，DEX一定是大势所趋，技术的前进通常是在循环往复的改良中螺旋向上，让我们拭目以待。
