vote The following contracts are quite complex, but show a lot of solidity features. Implement a voting contract. Of course, the main problem with electronic voting is how to allocate the right to vote to the right people and how to prevent manipulation. We will not solve all of the problems here, but at least we will show how to conduct a commission vote so that the votes are automatically and completely transparent. The idea is to create a contract

C-language dummies (1): nested loops-program structure, dummies Loop statement nesting a loop structure can contain another loop, called loop nesting, or multiple loops. The nested loop is a double loop. The outer loop is called an external loop, and the inner loop is called an internal loop. --------- I don't know where the basic concepts come from 　　 　　This is the first blog of the baby.

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

Solidity is a smart contract-oriented programming language. This is a four-year-old language designed to help develop smart contracts based on the Ethereum digital currency. Understanding its official documentation should be the best source of learning solidity: Solidity.readthedocs.ioWant to create your own cryptocurrency on the Ethereum network? Want to have your own initial code product? Here's the best

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
