“Solidity is statically typed, supports inheritance, libraries and complex user-defined types among other features.” Solidity docs Store information about an application, such as domain registration information or membership records.Provide utility to other contracts (similar to how a software library works).Manage agreements between users, say, if one buys insurance from the other.Function as multi-signature accounts, so that funds are spent only when a required percentage of people agree.So basically the contracts can be executed by your application s users as long as Ethereum exists. They will exist and be executable as long as the whole network exists, and will only disappear if they were programmed to self-destruct. Contracts are defined by their creators (developers), but their execution is provided by the Ethereum network itself. They contain functions and can interact with other contracts, make decisions, store data, and send ether to others. Smart contracts are just accounts on Ethereum blockchain that can be programmed to self-execute. First things first: What is a Smart Contract? In the process, you get familiar with Remix, in-browser IDE (integrated development environment) for developing smart contracts, and Solidity programming language. If you follow the steps right, by the end of this blog you will have created a (not so smart) smart contract that will contain some data stored on a blockchain. If you want to learn more about Ethereum before you start coding, I would suggest you read this article. This blog aims to help you break the “this is impossible” barrier that magically appears in the beginning (been there) and sets you up for a great start. Even though the technical documentation I had was great, making the first code steps were surprisingly hard. So I decided to work on Solidity smart contracts. When I realized all the possibilities blockchain provides, I immediately wanted to create something. Beginner s guide for setting up your first Solidity smart contract.
