Web3 Domains Explained

Blockchain-based domains are here. Here's how they work, when they're useful, and whether you should get one.

What Are Web3 Domains?

Web3 domains are stored on blockchains instead of traditional DNS servers. They're:

  • Decentralized: No central authority controls them
  • Owned, not rented: You own the NFT, not a subscription
  • Censorship-resistant: Can't be seized by governments (in theory)
  • Multi-use: Website + wallet address + identity

Major Web3 Domain Systems

ENS (Ethereum Name Service)

SEO/Indexing Full support Not indexed by Google

Should You Get a Web3 Domain?

✓ Good For

  • • Receiving crypto payments (human-readable wallet)
  • • Web3 identity/username
  • • Crypto-native projects
  • • Censorship-resistant content

✗ Not For

  • • Primary business website
  • • SEO-dependent sites
  • • Mainstream audiences
  • • E-commerce stores

Practical Recommendation

For most people and businesses: Keep your traditional .com for your primary presence. Add an .eth or .crypto as a secondary identity for crypto payments and Web3 credibility.

Think of Web3 domains as supplements to traditional domains, not replacements.
