去中心化 DEFI 质押流动性挖矿项目开发案例（逻辑分析）

所谓 DeFi，即 Decentralized Finance，被称作：《hkkf5566，可加薇》去中心化金融或者分布式金融。去中心化金融是指那些在开放的去中心化网络中发展而出的各类金融领域的应用，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。

　　To develop a DAPP,you must first understand what problems the DAPP can solve,and then write a project white paper describing

　　普通的开发者大多会选择一个相对成熟的平台,依托平台成熟的开发环境来开发自己的 DAPP。如此以来,DAPP 的开发工作就简单了不少。

　　The technical principle and consensus mechanism used by the DAPP.It is too complicated to develop a complete blockchain project from scratch,so at present

　　当前,DAPP 的最流行的开发平台是 Ethereum(以太坊)。Ethereum(以太坊)是一个图灵完备的区块链一站式开发平台,采用多种编程语言实现协议,采用 Go 语言写的客户端作为默认客户端。任何人在平台中建立和使用通过区块链技术运行的分布式应用。我们可以把它理解为区块链领域的

　　Android,它是一个开发平台,用户可以像基于 Android Framework 一样基于区块链技术开发应用

　　DeFi 的不同形式有哪些？

　　就像存在许多不同的去中心化应用一样，也存在许多不同的去中心化金融应用，包括:

　　1.Payment-decentralized financial applications of payment type generally have their own digital currencies.Users can use them for transactions and also provide money/package addresses for users to hold these digital currencies.

　　2.Borrowinglending-decentralized borrowinglending is a core application to try to decentralize the economy.Unlike now,people have to go to the bank to obtain housing loans.The goal of decentralized lending is to allow people to obtain loans from more capital lenders and democratize the whole process of lending.

　　3.Stable currency-stable currency is an asset with price stability characteristics,so it is suitable for functions such as transaction medium,bookkeeping unit and value storage.Compared with digital assets such as bitcoin,Ethereum and other highly volatile digital assets,stable currency has attracted more and more attention in the field of digital assets because of its stable price.

　　4.Decentralized exchanges-decentralized exchanges allow users to exchange digital assets such as bitcoin and Ethereum.Decentralized exchanges are created to solve the problems of centralized exchanges.Users in centralized exchanges do not have their own private keys,so they cannot control their own property.

　　目前，DeFi 项目已有数千个，除了以上四种类型，还有去中心化钱包、保险平台、预测市场、身份认证等都是属于 DeFi 的范畴。我们可以看到一个全新行业的早期阶段，整个 DeFi 生态系统正在蓬勃发展时期。
