Learn Solidity: Main Concepts and Principles Explained
After cryptocurrencies had such a drastic effect on the world, blockchain became the next big thing in IT. To learn Solidity and the way it writes smart contracts, you have to be familiar with blockchain as well. Smart contracts are a crucial part of the Ethereum blockchain. Therefore, learning about blockchain first is essential.
Since lots of enterprises are incorporating blockchain into their businesses, you have to learn Solidity which was designed according to the principles of the Ethereum Virtual Machine (EVM).
So how does blockchain work? In the most general sense, blockchain means a public database that stores digital information. These steps explain how blockchain works and handles transactions between parties:
- A transaction takes place.
- All transactions in the blockchain have to be verified.
- All verified transactions are given a unique code called hash.
- Transactions are stored in the database, together with tons of other similar transactions.
Blockchain fuels the cryptocurrency machine and allows transactions between two parties. One of the most notorious aspects of blockchain is privacy: users can conceal their identity, and other parties can only get a person's digital signature or a username.
How does Ethereum work? It is a blockchain-based platform, allowing programmers to develop decentralized applications and run their programming codes. In Ethereum blockchain, miners mine to get Ether: the crypto token of this network. This token can be used to pay for various services and resources on the Ethereum platform.
Solidity is a new object-oriented programming language, created to make contracts on various blockchain platforms. It was first introduced in 2014 by Christian Reitwiessner.
Since then, this ECMAScript-based programming language has become popular all over the globe, with millions of users executing their smart contracts every day.
Why You Should Learn Solidity: Purpose and Use
On the EVM, developers can use a variety of languages like Serpent or LLL. However, many prefer to work with Solidity because of its advantages:
- Smart contracts: you can use complex member variables.
- Inheritance Support: you can base an object on another object or a class on another class.
- Application Binary Interface (ABI): guarantees type safety with the Solidity command line compiler.
Where to Start
If you decide to learn Solidity, you should consider a couple of things:
- Read Solidity introduction which will provide a short description of this language and offer useful tools (Remix, plugins).
- Study an example of a smart contract. Try out this code with Remix.
- Analyze other tutorials. At first, you will be introduced to the basics of blockchain and Ethereum Virtual Machine. Later, you will learn about error handling, function modifiers, etc.
- Practice with the provided Solidity code examples.
- Consider checking our interactive and video courses about Solidity, blockchain, and Ethereum.
