Blockchain Development: Building DApps on Ethereum

Blockchain technology is revolutionizing various industries. This guide will help you understand the fundamentals of blockchain development and how to build decentralized applications.

Smart Contract Development

// Example Solidity smart contract
pragma solidity ^0.8.0;

contract Token {
    string public name;
    string public symbol;
    uint8 public decimals;
    uint256 public totalSupply;
    mapping(address => uint256) public balanceOf;

    event Transfer(address indexed from, address indexed to, uint256 value);

    constructor(string memory _name, string memory _symbol) {
        name = _name;
        symbol = _symbol;
        decimals = 18;
        totalSupply = 1000000 * (10 ** uint256(decimals));
        balanceOf[msg.sender] = totalSupply;
    }
}
