Web3

A vision of the internet built on decentralized blockchains and tokens, contrasted with Web2's platform-monopoly model.

The Web3 framing came from Ethereum cofounder Gavin Wood (~2014). The thesis: Web1 was read-only static pages, Web2 added interactivity at the cost of centralized platforms (Facebook, Google) owning user data, and Web3 returns ownership to users via cryptographic primitives — wallets as identity, NFTs as digital property, tokens as governance and incentives.

In practice, Web3 today encompasses crypto wallets (MetaMask, WalletConnect), decentralized identity (ENS, Lens), decentralized social (Farcaster), decentralized storage (IPFS, Arweave), and DAO-governed protocols. Pure Web3 alternatives to mainstream apps remain niche; hybrid Web2+Web3 (apps with wallet login + on-chain payments) is more common.

Critics argue most "Web3" infrastructure is centralized in practice (Infura serves most Ethereum RPC calls; OpenSea dominates NFTs). Proponents argue this is transitional — the standards are open, and decentralization improves over time. The ideological vs practical gap is the dominant fault line in Web3 discourse.

Why it matters

Web3 is the umbrella term for crypto's consumer-facing ambitions. Its trajectory determines whether crypto stays trader-focused or expands into mainstream apps.

FAQ

Is Web3 just a buzzword?

It's contested. Specific Web3 primitives (wallets, NFTs, DAOs) are real and used. Whether they form a coherent next-generation internet is genuinely debated, including by people who built core Web3 tech.

Do I need crypto for Web3?

Most Web3 apps require a crypto wallet, even if you don't hold significant value in it. Some (like ENS for identity) work with minimal balances. The wallet is the identity primitive, more than the holding.

Is Web3 better than Web2?

Trade-offs. Better: user ownership, censorship resistance, programmability. Worse: UX, performance, security responsibility on user. Most users prefer Web2 convenience until specific Web3 use cases become compelling for them.

Will Web3 replace Web2?

Unlikely as full replacement. More likely: hybrid where specific functions (identity, payments, asset ownership) move on-chain while content, social graphs, and apps stay mostly Web2.
