Decoding the Role of Blockchain, Crypto and AI in Today’s Software Development

How to Develop a Simple Smart Contract Using Solidity on Ethereum Blockchain

Blockchain, Smart Contract development and Cryptocurrencies are no longer future technology concepts. They’re here, and they’re changing the world. Solidity is an object-oriented, high-level language for developing smart contracts that run on the Ethereum Virtual Machine.

Step 1: Environment Setup

To begin developing with Solidity, software must first be installed. Acquire a text editor like Atom, Notepad++ or Sublime and install an Ethereum coding environment like Remix or Truffle Suite.

Step 2: Learning Basic Syntax to Say “Hello World!”

Solidity’s syntax is similar to JavaScript’s, which makes it relatively simple to grasp. A basic code snippet could look like this:

pragma solidity ^0.5.0; // declare compiler version
contract HelloWorld { // declare contract
function sayHello() public { // declare function
return ‘Hello World!’;

Step 3: Developing a Simple Smart Contract

Let’s create a more complex contract––one that manages a simple storage.

pragma solidity ^0.5.0;
contract SimpleStorage {
uint public storedData; // declare variable
function set(uint _storedData) public { // declare function to set variable
storedData = _storedData;
function get() public view returns (uint) { // declare function to get variable
return storedData;

Step 4: Testing Our Smart Contract

Testing is key to ensure the solidity script works as expected. With Remix, you can test your contract with the JavaScript VM.

Step 5: Deploying Our Smart Contract

The very last step is to deploy our contract onto the Ethereum network.

In conclusion, Solidity is an indispensable language for anyone seeking to leverage the power of smart contracts on the Ethereum blockchain. And this paramount power requires one’s understanding and ability to utilize an object-oriented, high-level language such as Solidity.
