Solidity Tutorial — A Detailed Introduction

Blockchain technology has been quite a buzz in the market. There has been considerable development in this technology. Similar to other technologies like AI, Blockchain has also evolved with time. When we are talking about Blockchain, it becomes important to mention smart contracts. This has been one of the most revolutionary additions and also holds strong prospects for the future. Smart contracts find a multitude of applications. If you are also willing to become a Blockchain professional, it is important to learn about the various concepts, including the high-level programming language like Solidity. Besides, you also need to have expertise in Python, Java, and C++. But for now, let’s shift our focus on Solidity. This blog highlights the basics of Solidity.

What is Solidity?

Solidity gained popularity in 2015. It is a high-level programming language that is focused on designing and implementing smart contracts. It has a special orientation towards Ethereum Virtual Machine. Here are some of the key features of Solidity:

1. It is a statistical type of language used for smart contracts.

2. It is used for creating contracts

Setting up Solidity

The following section highlights the different ways of setting up Solidity:

npm / Node.js- If you don’t have a Linux machine, you can set up Solidity on a CentOS machine. To install Solidity, you need to ensure the availability of node.js available. For ease of installation, you can use a Solidity compiler named solc-js.

Pulling a Docker image- You can pull a docker image and use it for Solidity programming. To start with this process, you must use the command: $docker pull ethereum/solc:stable

Once you have done this, the next step is the verification of the docker image. $docker run ethereum/solc:stable-version

Binary package installation- The next method is binary package installation. Solidity offers a snap package for installing Solidity of all the compatible Linux distributions. Since the snap packages have stringent regulations, it ensures a secured environment.

Understanding the syntax

Once you have set up Solidity, the next thing that you need to understand is solidity syntax. Besides, you also need to know about the codes of Solidity that will help you in setting up the basics of smart contracts. So here is what you need to know :

Pragma- This is the first line of code is the Pragma directive, which is usually written in Solidity version 0.4.0. A program directive is specific to a source file. In simple words, a Pragama for a file that could no compile with earlier version 0.4.0 will not work version 0.5.0

Import file- The next step is to import the files. To import the file, all you need to do is to simply type import “XYZ”;

Reserved keywords- To understand Solidity better, one must learn about the various reserved keywords that simplify the task. Some of the reserved keywords that you need to know are:

Immutable

Type

After

Switch

Case Abstract

Auto

Alias

Default

Override

Size

Unchecked

Typedef

Inline

Copy of

Apply

Reference

Try

Static

Define

Wrapping it up !!!

This was the basic information about Solidity. However, there is much more to it. To get an in-depth understanding of Solidity, you can enroll for the certification program. The blockchain certification program will equip you with all such details.

Blockchain education includes different concepts like smart contracts, understanding the functioning of the system, and much more. If you, too, are planning to become a Blockchain expert, this is the right time to enroll or the Blockchain certification program. The Blockchain Council offers comprehensive learning programs in Blockchain. With this certification program, you will learn about Blockchain technology and its practical applications as well.
