Learn how to write your first BitTorrent Chain (BTTC) smart contract and understand core concepts like state variables and public functions.





According to BitTorrent Inc., they have released a beginner-friendly guide to writing smart contracts on the BitTorrent chain (BTTC). The guide aims to help new developers understand the basics of blockchain development through a simple ‘Hello World’ project.

Contract: Small in size but big in potential

This tutorial provides a concise, yet powerful HelloWorld contract.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.17;
contract HelloWorld
string public greet = "Hello World!";
function getGreeting() public view returns (string memory)
return greet;

This contract serves as a building block for more complex smart contracts by introducing core concepts such as state variables and public functions.

Digital DNA Decoding

Greetings: Our Blockchain Billboard

string public greet = "Hello World!";

This public string variable acts as a persistent message that displays ‘Hello World!’ for everyone to see on the BTTC network.

Getter: Bringing our friendly message

function getGreeting() public view returns (string memory) 
return greet;

This feature allows users to search for greeting messages without changing the contract status.

Why are there two ways to say hello?

This guide explains why we have both public variables and getter functions.

  1. Direct variable access: The public keyword automatically generates a getter function, allowing you to read variables directly from the blockchain.
  2. Custom Functions: The getGreeting() function demonstrates how to create a custom method that can include additional logic or return multiple values.

Beyond the Basics: Where to Next?

This tutorial encourages developers to explore further by modifying the greeting message, adding logic, or connecting the contract to a front-end application.

The Power of Hello World

Although simple, the HelloWorld contract serves as an introduction to decentralized applications and covers essential concepts such as state variables and public functions, which are the building blocks of more complex smart contracts and DApps.

Bonus Section: Learn more about BTTC Smart Contracts

For those who want to advance their skills, BitTorrent Inc. provides a comprehensive GitHub repository, which includes:

  1. Deployment script: A script that can be used to deploy smart contracts on the BTTC network.
  2. Comprehensive Test: A suite of tests to ensure the reliability and security of smart contracts.
  3. Multiple projects: Various smart contract examples demonstrating different aspects of BTTC-based blockchain development.
  4. documentation: A detailed README file and inline comments are provided to help you better understand and modify the code.

Get started

To utilize these resources:

  1. Clone the repository: git clone https://github.com/adeelch9/bttc-examples.git
  2. Go to your desired project directory
  3. Follow the setup instructions in the project’s README.
  4. Experiment with contracts, run tests, and try deploying them to testnets.

Why this matters

Exploring the entire repository will provide you with a deeper understanding of smart contract development, hands-on experience with deployment and testing, and exposure to best practices in blockchain development.
