Understanding Ethereum and DApps
Ethereum is a decentralized, open-source blockchain platform that enables developers to build and deploy decentralized applications (DApps). These applications are designed to operate on a distributed network, eliminating the need for a central authority.
Key Concepts of Ethereum
Ethereum’s core functionality is powered by smart contracts, which are self-executing programs stored on the blockchain. These contracts automate agreements and enforce their terms without the need for intermediaries. Ethereum also uses its native cryptocurrency, Ether (ETH), as a fuel for transactions and interactions within the network.
Differences Between Traditional Applications and DApps
Traditional applications are centralized, meaning they rely on a single server or entity to operate. This central point of control can make them vulnerable to security breaches and censorship. DApps, on the other hand, are decentralized, meaning they are distributed across a network of computers.
This makes them more resistant to censorship and single points of failure.Here’s a table summarizing the key differences:
Feature | Traditional Applications | DApps |
---|---|---|
Control | Centralized | Decentralized |
Security | Vulnerable to single points of failure | More secure due to distributed nature |
Censorship | Susceptible to censorship | Resistant to censorship |

Basic Smart Contract Examples
Let’s explore how to write basic smart contracts for common functionalities:
Token Creation
“`soliditypragma solidity ^0.8.0;contract MyToken string public name = “My Token”; string public symbol = “MYT”; uint256 public totalSupply = 1000000; // Total supply of tokens mapping(address => uint256) public balances; // Mapping to store balances for each address constructor() balances[msg.sender] = totalSupply; // Initialize the creator’s balance function transfer(address to, uint256 amount) public require(balances[msg.sender] >= amount, “Insufficient balance”); balances[msg.sender]
= amount;
balances[to] += amount; “`This simple contract defines a token called “My Token” with a symbol “MYT” and a total supply of 1 million tokens. The `transfer` function allows token holders to send tokens to other addresses.
Voting
“`soliditypragma solidity ^0.8.0;contract Voting string public proposal; mapping(address => bool) public hasVoted; uint256 public yesVotes; uint256 public noVotes; constructor(string memory _proposal) proposal = _proposal; function vote(bool choice) public require(!hasVoted[msg.sender], “Already voted”); hasVoted[msg.sender] = true; if (choice) yesVotes++; else noVotes++; “`This contract allows users to vote on a specific proposal.
The `vote` function registers votes for “yes” or “no” options, preventing double voting.
Data Storage
“`soliditypragma solidity ^0.8.0;contract DataStorage mapping(uint256 => string) public data; function storeData(uint256 key, string memory value) public data[key] = value; function retrieveData(uint256 key) public view returns (string memory) return data[key]; “`This contract allows users to store and retrieve data associated with unique keys.
The `storeData` function stores data, and the `retrieveData` function retrieves it based on the provided key.
