What is Web3 Development?

Web3 development refers to creating applications and systems that run on decentralized networks, such as blockchain. Unlike traditional Web2 development, Web3 focuses on decentralization, transparency, and user control.

Key aspects of Web3 development include:

  1. Blockchain Technology: The foundation of Web3, enabling secure and immutable transactions.
  2. Smart Contracts: Self-executing contracts coded on blockchain networks like Ethereum.
  3. Decentralized Applications (dApps): Applications that run on peer-to-peer networks instead of centralized servers.
  4. Tokenization: Integrating cryptocurrencies or NFTs for digital ownership and payments.

Web3 developers typically work with programming languages like Solidity and tools like Hardhat, Truffle, and Web3.js to build applications.
