Setting Up A Simple Smart Contract in Ethereum Blockchain
Blockchain is taking the world by storm with its potential applications in various fields. Today, we will be looking at one application of it – Ethereum – and how to set up a smart contract using Solidity language.
Step 1: Setting Up Environment
Before we dive into creating a smart contract, it is important to first set up your development environment. You can use Remix, an online IDE that is specifically designed for Solidity development.
Step 2: Writing Smart Contract Code
Now, it’s time to write a simple smart contract. In today’s tutorial, we’ll be creating a basic contract which allows anyone to store a single number.
“`solidity
pragma solidity ^0.4.0;
contract SimpleStorage {
uint storeddata;
function set(uint x) public {
storeddata = x;
}
function get() public view returns (uint) {
return storeddata;
}
}
“`
The above code is basically creating a state variable called storeddata which will store an unsigned integer. The true core of this contract is based on two methods, ‘set’ and ‘get’.
Step 3: Compiling the Contract
Once you’ve written the code, the next step is to compile it. On Remix, you’ll find a compilation tab where you can easily compile the smart contract.
Step 4: Creating an Instance
After a successful compilation, navigate to the ‘Run‘ tab to create an instance of the smart contract. Using this instance, you can interact with the contract.
Step 5: Running the Contract
Under the ‘Run‘ tab, you’ll see a dropdown containing all available contracts. Select SimpleStorage and click on ‘Create’ to deploy it to the blockchain.
Now you’re all set to run and interact with your simple Smart Contract! You can use the ‘set’ function to store a value and ‘get’ function to retrieve it.
Remember, block matrices and hashes play a vital role in the ethereum blockchain. Matrices are responsible for storing all data and smart contracts, while hashes uniquely identify these blocks.
Conclusion
In this tutorial, we learnt how to launch a simple smart contract onto an Ethereum blockchain. While the applications of smart contracts are vast, the basic principle remains consistent. Master this, and you’re on the road to becoming a prominent player in the booming era of blockchain!
