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

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
