Web3

Web3 represents the next evolution of the internet, built on decentralized technologies like blockchain, smart contracts, and token-based economics. It aims to shift power from centralized platforms to users.

Web1 was read-only (static websites), Web2 is read-write (social media, user-generated content controlled by platforms), and Web3 is read-write-own (users own their data, identity, and digital assets through cryptographic keys).

Key Web3 technologies include blockchain networks (Ethereum, Solana, Polygon), decentralized storage (IPFS, Arweave), decentralized identity (ENS, DIDs), and wallet-based authentication (MetaMask, WalletConnect).

Building Web3 applications involves connecting frontend frameworks (React, Next.js) to blockchain networks using libraries like Ethers.js, Viem, or Wagmi. The tech stack typically includes a smart contract backend, decentralized storage for assets, and a traditional frontend for the user interface.
