Dapp商城开发平台丨dapp商城系统开发详细及逻辑

The blockchain mall system is mainly based on blockchain technology to create an e-commerce ecosystem and build a decentralized business ecosystem. By connecting the value of digital assets and real business, we will perfectly combine powerful offline experiential services with efficient blockchain internet finance, provide more efficient and valuable intelligent services for users and merchants, and realize the blockchain transformation of commercial services. Blockchain is a distributed database (system) placed in a non-secure environment. It uses cryptographic methods to ensure that existing data cannot be tampered with. At the same time, blockchain uses consensus algorithms to reach consensus on new data. Based on the above characteristics, the current situation of data transaction can be completely changed in data transaction, and a variety of solutions and design ideas have been produced. The following is mainly explained from the perspective of blockchain technology in solving data ownership on the big data transaction platform. 　　合约初始化 　　公共函数（合约内外部都可以调用） 　　constructor 　　代码速览 　　constructor()public{ 　　factory=msg.sender; 　　}商城系统：I35 system 7O98 development o7I8 　　参数分析 　　函数constructor的入参有0个，出参有0个。 　　在合约初始化时，Pair合约会将msg.sender记录为factory地址。 　　实现分析 　　... 　　{ 　　//设置factory地址 　　factory=msg.sender; 　　} 　　总结 　　Pair合约初始化时，会记录factory地址。 　　外部函数（仅合约外部可以调用） 　　initialize 　　代码速览 　　function initialize(address _token0,address _token1)external{开发流程：mrsfu123 　　require(msg.sender==factory,'UniswapV2:FORBIDDEN'); 　　token0=_token0; 　　token1=_token1; 　　} 　　参数分析 　　函数initialize的入参有2个，出参有0个，对应的解释如下： 　　function initialize( 　　address _token0,//token0地址 　　address _token1//token1地址 　　)external{ 　　... 　　} 　　由于create2函数无法传参，因此需要再次调用initialize函数来记录token0和token1的地址。 　　实现分析 　　... 　　{ 　　//检查msg.sender地址等于factory地址 　　require(msg.sender==factory,'UniswapV2:FORBIDDEN'); 　　//记录token0和token1地址 　　token0=_token0; 　　token1=_token1; 　　} 　　总结 　　由于initialize是初始化函数，因此只能由factory调用，且只会调用一次。
