Solidity is the high-level language of contract-oriented implementation of smart contracts. It is influenced by C ++,python and JavaScript and is designed for Ethereum virtual machines (EVM). Solidity is a static type that supports features such as inheritance, libraries, and complex user-defined types. You will see that you can create contracts for voting, crowdfunding, blind auctions, multi-signature wall

In the course of my research on the technology of Ethernet square, due to the relatively few data, it took a lot of detours. So here we will not first introduce the grammatical structure of solidity, but will be in the next phase, from the actual combat, to introduce you to Geth, browser-solidity, mist these three tools, and in the process of constantly explaining the basic concept of the ether. Through the

A simple smart contractStart with a very basic example, and don't worry that you don't know it at all, and we'll get to know more details.Storecontract SimpleStorage { uint storedData; function set(uint x) { storedData = x; } function get() constant returns (uint retVal) { return storedData; }}In solidity, a contract consists of a set of code (the function of the contract) and the data (the state of the contract). The cont

Introduction: In the previous section, we talked about developing specifications for developing smart contracts on the juice platform, and we will continue to discuss the solidity-defined assembly language in more depth in this section.The assembly language defined by solidity can achieve the following objectives:1. Use it to write code that is readable, even if the code is compiled from

Use * * Ethereum wallet DEVELOPMENT * * To achieve the classic Helloword smart contract class. In this article, we'll see how to write a simple contract and deploy it to a blockchain. We'll also learn how to interact with our smart contracts by sending and reading data. Solidity's contract syntax is actually similar to classes in object-oriented programming languages. Smart contracts have functions that we can call and variables that can be stored and read. Our ' Counter ' contract will store th

In the first article in this series, I introduced the concept of a non-fake token (NFT) and the need for the ERC721 (draft) standard.In this article, we will first introduce the ERC721 standard interface and decompose some requirements. There will also be a brief but important detour on the ERC165 standard. "Todd Quackenbush's display of a toolkit on Unsplash shows tool interfaces and ERC165 standards such as hammers, axes, box cutters, iron and flashlights. The ERC721 standard states: "Every co

Assign Value (Assignment) deconstruct assignment and return multiple results (destructing Assignments and returning multip values) The solidity built-in support tuple (tuple), that is, supports a list of possible completely different types, fixed in number (tuple generally refers to two, and a triple generally refers to three). This built-in structure can return multiple results at the same time, and can also be used to assign values to multiple var
