DAPP系统开发步骤介绍详情

DAPP被认为开启了区块链3.0时代。它是在底层区块链平台衍生的各种分布式应用，是区块链世界中的服务提供形式，其基于P2P对等网络而运行在智能合约之上的分布式应用程序，区块链则为其提供可信的数据记录。

DAPP is considered to have opened the block chain 3.0 years. It is a variety of distributional applications derived from the bottom block chain platform and a service delivery form in the block chain world. It operates a distributional application based on a P2P peer-to-peer network that provides reliable data records.

DAPP通过网络节点去中心化操作，可以运行在用户的个人设备之上，例如手机、个人电脑。永远属于用户，也可以自由转移给任何人。DAPP系统开153发技术搭o56o建源码1oo3：DAPP运行在对等网络。不依赖中心服务器，不需要专门的通信服务器传递消息，也不需要中心数据库来记数据。数据保存在用户个人空间。数据加密后存储在区块链上。可以依托于区块链进行产权交Y、销√售，承载没有中√介的交Y方式。

DAPP is centralised through a network node and can run over the user’s personal devices, such as mobile phones and personal computers. It always belongs to the user or can be freely transferred to anyone. The DAPP system runs the peer-to-peer network with 153 rounds of technology, i.e. the source code 11o3:DAPP. There is no reliance on a central server, no need for a dedicated communications server to transmit messages, or a central database to record data. The data is stored in the user’s personal space. The data is stored on the block chain after encryption.

DAPP项目中的代码是属于开源的，这是只有去中心化应用才会有的特点，DAPP系统的代码完全开源，可供所有人观看或应用。

The codes in the DAPP project belong to open sources, which are characteristic only of decentralised applications, and the DAPP system is fully open for viewing and application by all.

如果想要开发DAPP系统时的步骤大致可分为三步，首先要开发智能合约，通常使用solidity语言进行开发，选用以太坊合约、bsc合约等，接着部署智能合约，通常使用remix工具进行部署，先在测试环境中进行部署智能合约，申请对应的测试币；He~fei~艾数大数据专/业区块链项目开/发；然后就是开发dapp前端，使用前端框架进行开发，前端设计到和钱包的连接、调用合约、数据查询等内容。

If the steps to be taken to develop the DAPP system are to be roughly three-step, the first is the development of a smart contract, which is usually developed in the language of soliity, which is selected for the Taiyo contract, the bsc contract, etc., followed by the deployment of the smart contract, which is usually deployed using the remix tool, which is deployed in a test environment and applies for the corresponding test currency; the second is the development of the dapp front end, which is developed using the front-end framework, which is designed to connect to the wallet, call the contract, data queries, etc.
