What is Ethereum Name Service (ENS)?

·

Updated: Month Day, Year

KEY TAKEAWAYS
— ENS simplifies Web3 interactions by replacing complex blockchain addresses with human-readable .eth domains.
— Built on Ethereum, ENS domains are secure, private, and resistant to censorship.
— Domains can link to crypto wallets, IPFS data, or function as tradable NFTs.
— This guide covers ENS basics, fun facts, and steps to register your own .eth domain.

Looking to claim your .eth domain? Here’s everything you need to know!


From DNS to ENS: The Evolution of Naming Services

Imagine typing 104.18.24.74 instead of ledger.com to visit a website. Early internet users faced this hassle until Domain Name Service (DNS) emerged, bridging human-friendly names with machine-readable IP addresses.

But DNS, designed for Web2, relies on centralized control—a mismatch for Web3’s decentralized ethos. Enter Ethereum Name Service (ENS), a blockchain-powered alternative.


How ENS Works

ENS transforms unwieldy Web3 identifiers (e.g., 0x3bsfjbk234basf8iwerb…) into simple domains like batman.eth. Key features:

👉 Secure your ENS domain with a Ledger wallet


Why Choose ENS? Fun Facts About .eth Domains

  1. Censorship-Resistant: Governments can’t block .eth domains.
  2. Human-Friendly Payments: Share yourname.eth instead of a 42-character wallet address.
  3. Web3 Identity: Use domains for logins, donations, or content hosting.
  4. Investment Potential: Rare domains (e.g., token.eth) appreciate like premium DNS names.

How to Register a .eth Domain in 5 Steps

  1. Connect Your Wallet: Visit app.ens.domains and link a crypto wallet (e.g., MetaMask).
  2. Search a Domain: Enter your desired name (e.g., cryptoqueen.eth).
  3. Check Availability: If greenlit, proceed to registration.
  4. Choose Duration: Pay in ETH—fees vary by name length and lease period.
  5. Confirm Transaction: Approve via your wallet. Voilà—you’re a Web3 domain owner!

ENS FAQs

Q: Can I transfer my ENS domain?
A: Yes! Treat it like any NFT—sell or gift it via marketplaces.

Q: How much does registration cost?
A: Prices depend on demand. Short names (3+ characters) start at ~$5/year.

Q: Is ENS only for Ethereum?
A: Primarily, but cross-chain support is expanding.


The Future of Web3 Domains

With 300,000+ ENS domains registered and adoption growing, .eth could become the .com of Web3. As blockchain interoperability improves, expect ENS to anchor decentralized identities across ecosystems.
