# 什么是DeFi

DeFi全称为Decentralized Finance，即“去中心化金融”或者“分布式金融”。它与传统中心化金融相对，指建立在开放的去中心化网络中的各类金融领域的应用，用户无需再在中心化机构的辅助下参与金融市场，而是可以利用去中心化网络中的开源软件获得、交易并借贷资产。通俗的说，就是建立一个对所有人开放的新金融系统，不需要如银行这类的中介机构。

DeFi的目标是建立一个多层面的金融系统，以区块链技术和密码货币为基础，重新创造并完善已有的金融体系。

当前，几乎全部的DeFi项目都在以太坊的区块链上进行，智能合约是 DeFi的主要构建模块。如今最常见的几类 DeFi Dapp主要有Compound、MakerDAO、Synthetix、去中心化交易所（例如Uniswap）等。
