What is the Ethereum Name Service (ENS)?

Key Takeaways:

• Similar to Domain Name Services (DNS) that simplify web access via names, Ethereum Name Service (ENS) provides human-readable addresses for Web 3.0 on the blockchain.
• ENS operates on the Ethereum Blockchain, enabling users to purchase secure, private, and censorship-resistant .eth domain names.
• These domains can link to crypto wallet addresses or other data stored on decentralized platforms like the Interplanetary File System (IPFS).
• This article explores ENS, fun facts about .eth domains, and how to acquire one for yourself.

The Evolution: From DNS to ENS

Initially, internet access required typing complex IP addresses. DNS simplified this by mapping domain names to IPs. However, DNS belongs to Web 2.0—centralized and controlled by entities. For Web 3.0, we needed a decentralized alternative: Ethereum Name Service (ENS).

What is ENS?

ENS translates lengthy blockchain identifiers (e.g., wallet addresses 0x3bsfjbk234basf8iwerb…) into readable names like batman.eth. Key features:

• Decentralized: Runs on Ethereum, immune to single-point control.
• Smart Contract-Based: Automates domain registration without intermediaries.
• Subdomain Ownership: If you own batman.eth, create subdomains like donate.batman.eth.

Unlike DNS, ENS domains are:

• Censorship-resistant: No authority can block your .eth domain.
• NFTs: Domains are ERC721 tokens, tradable on marketplaces like OpenSea.

Fun Facts About .eth Domains

1. Simplified Payments: Share yourname.eth instead of a 42-character wallet address.
2. IPFS Integration: Link domains to files stored on IPFS for decentralized websites.
3. Future-Proof: Over 300,000 ENS domains are registered—potentially the .com of Web 3.0.

How to Get a .eth Domain

1. Connect Your Wallet: Visit app.ens.domains and link a crypto wallet (e.g., MetaMask).
2. Search Your Domain: Check availability (e.g., yourname.eth).
3. Register: Choose registration duration (1+ years), approve the transaction, and pay (cost varies by domain length).
4. Configure: Link the domain to your wallet or IPFS content.

The Future of ENS

With Ethereum’s dominance, .eth domains could become the standard for Web 3.0—just as .com did for Web 2.0. Over 100,000 users already own ENS domains, signaling rapid adoption.

FAQ

Q: Can I transfer my ENS domain?
A: Yes! ENS domains are NFTs, transferable via crypto wallets.

Q: Are ENS domains permanent?
A: They expire if not renewed. Set reminders!

Q: How much does a .eth domain cost?
A: Prices depend on length (e.g., 3-character domains cost more) and registration duration.

Q: Can I use ENS with other blockchains?
A: Primarily Ethereum, but bridges to other chains are emerging.
