What is Solidity?

Solidity is the primary programming language for writing smart contracts on the Ethereum blockchain. It’s a contact-oriented language that basically means that Solidity smart contracts are the main way to write all of your programming logic, organize code, and store data. Solidity is the main driving force behind Ethereum. It’s a high-level language for implementing smart contracts. This language is much similar to and influenced by Python, C++, and JavaScript.

Frequently Asked Questions

How do I get started with Solidity?

If you are willing to learn Solidity, you may find some of the best tutorials, tools, and resources online to help you get started. All these tutorials and resources will help build your Solidity knowledge. Alternatively, you may also refer to Solidity docs, where you can learn the basics about blockchain, Ethereum Virtual Machine(EVM), and smart contracts. 

How long does it take to learn Solidity?

You can quickly grasp Solidity within a few months if you are already a programmer or likely have experience with other programming languages available. For example, if you have prior experience in JavaScript, Python, or C++, it will be easy for you to adapt Solidity syntax. Most solidity developers learn by themselves, so your only barrier will be self-discipline. 

Is it really a good idea to learn Solidity?

Learning Solidity programming can sometimes be painful, but it is also a gratifying experience. Even the tiny mistakes in smart contracts might lose you a lot of money so learn testing, or you may have to face the consequences. However, all you need to do is to manage your transactions or gas fees. Furthermore, there is no going back once you pay to deploy a smart contract.
