Solidity is a key programming language in the Blockchain world.

In 2014, Solidity was proposed for the first time, and Ethereum’s Solidity team consistently worked on developing it. Currently, there are thousands of developers around the world using Solidity for creating blockchain-based services. You will find plenty of use cases of Solidity in the current world.

Now, let us understand a bit more about Solidity so that you can get a good idea about it.

What is Solidity?

Solidity is an object-oriented programming language created by the Ethereum Network team for designing and developing Smart Contracts in the Blockchain world. You can automate transactions and perform various other tasks through this programming language.

If you get towards the core of Solidity, you will find it pretty similar to JavaScript. So, if you are good with JavaScript, you can get easily acquainted with Solidity. On top of that, you will also find Solidity to be a bit similar to C++ and Python.

As Solidity is a high-level language, you will have to function with letters and numbers. So, it becomes pretty easy to understand. Just like Python, you will have to use the concept of inheritance and include various libraries for programming in Solidity.

There are plenty of use cases of Solidity programming that are pretty much visible in the blockchain world. Let us look through some of the most common use cases.

Solidity Programming Use Cases


Several issues like fake voters, booth capturing, data manipulation, and voting machine alterations are visible in the voting process. The voting process can be made transparent and effective by deploying Solidity smart contracts.


Crowdfunding often faces the issues of data management and third-party commission. There is no requirement for centralized systems when the entire process is handled through Solidity smart contracts. This will eventually reduce the additional costs.

Blind Auctions

Anyone can see another person’s bids if there is an open auction. This creates a lot of disputes and even some chances of fraud. Blind Auctions with Solidity smart contracts will not allow any individual to view another person’s bid until the auction gets over.

So, this might make it pretty clear that Solidity programming has high-value use cases.

Now, let us look through the pre-requisites for learning Solidity. This will help you a lot if you are thinking about learning this language.

Pre-requisites of Learning Solidity

Solidity is a high-level programming language for developing Ethereum-based Smart Contracts. As everything is connected with the Ethereum platform, you need to possess fundamental knowledge of the platform. Apart from that, the following are the pre-requisites of learning Solidity:

  • Basic understanding of Blockchain technology and its related platforms
  • Basic knowledge of programming and programming languages
  • Ability to work with technology

If you are from a computer background, it will be a plus point as things will be easier for you to learn. But even if you are from any other field, you can learn Solidity after getting basic knowledge of the Ethereum Blockchain.

This is all that you need to become a Solidity developer.

Impact of Learning Solidity for Becoming a Blockchain/Ethereum Developer

If you aim to become a Blockchain/Ethereum Developer, you need to be clear with Smart Contracts. The work of Blockchain Developer is to create DApps (Decentralized Apps), and Smart Contracts are its foundation.

For writing any smart contract, you will have to learn Solidity. The syntax is similar to JavaScript, but you will need a profound understanding of Solidity for writing smart contracts. Once you deploy any smart contract, it will perform the task autonomously with no intervention required from your end. You cannot modify the code at any time. It will keep on running forever.

If you wish to step into the field of Blockchain and develop smart contracts, then you need to get familiar with Solidity programming. Some key reasons to learn Solidity are:

  • Creating smart contracts to program money and move it based on certain conditions being met
  • Deploying smart contracts through EVM (Ethereum Virtual Machine)
  • Developing decentralized applications in every sector
  • Be clear with the ins and outs of the Ethereum blockchain by getting clear with Solidity

So, you can say that if you are thorough with Solidity programming, you will find it pretty easy to work with the Ethereum platform and other blockchain platforms. Solidity is the base for becoming an Ethereum /Blockchain Developer.

Now, you might have the most common question – “How to learn Solidity?” Well, you don’t need to worry because you will get the answer pretty soon.

Let us look through some of the best courses and resources to learn Solidity in the comfort of your home.
