Similar to the Domain Name System (DNS) that translates IP addresses into readable links, Ethereum Name Service (ENS) allows individuals and businesses to replace complex crypto addresses with human-readable names. This tool significantly enhances user experience in the crypto and Web3 space.
Unlike traditional domain names, ENS offers unique advantages when used correctly.

The Problem with Ethereum Addresses
Like internet protocol addresses, crypto wallet addresses are complex and difficult to memorize. Fortunately, developers created DNS, which links readable domain names to IP addresses. DNS translates IP addresses like 172.64.147.202 into user-friendly URLs like beincrypto.com.
Despite blockchain advancements, crypto transactions still rely on lengthy, hard-to-read addresses. For example, an Ethereum (ETH) address looks like this: 0xd0eAf74B8c5bF457C7a81c3fe277aDb6Ed32DCF4
Mistyping even one character can result in permanent fund loss. This is where Ethereum Name Service (ENS) comes in.
What Is Ethereum Name Service (ENS)?
ENS is an open, distributed naming system built on the Ethereum blockchain. Like DNS, it maps human-readable names (e.g., name.eth) to machine-readable addresses (e.g., Ethereum wallet addresses).
The ENS Team
ENS was launched in 2017 by Alex Van de Sande and Nick Johnson, former Ethereum Foundation members. Since 2018, it has been managed by True Names LTD, a Singapore-based nonprofit. The team includes experienced Solidity developers and Ethereum veterans.
In November 2021, ENS distributed governance tokens to users and established a Decentralized Autonomous Organization (DAO) to oversee the project.
The ENS Foundation
The ENS Foundation, registered in the Cayman Islands, provides legal support to the DAO. It operates as a nonprofit with no profit distribution to members.
Why Choose Ethereum Name Service?
ENS simplifies crypto transactions by replacing complex addresses with memorable names like Julie.eth. Key advantages include:
- Decentralization: Unlike DNS, ENS domains are stored on Ethereum’s blockchain, making them resistant to censorship and hacking.
- Multi-chain support: ENS can link to addresses on other blockchains (e.g., Bitcoin, Litecoin).
- Full control: Users own their domains and subdomains outright.
ENS vs. Domain Name System (DNS)
| Feature | ENS | DNS |
|---|---|---|
| Decentralization | Yes (Ethereum blockchain) | No (centralized servers) |
| Security | High (smart contract-based) | Vulnerable to attacks |
| Renewal | Annual fee (paid in ETH) | Varies by registrar |
ENS vs. Unstoppable Domains
- ENS: Open-source, decentralized, and governed by a DAO. Requires annual renewal.
- Unstoppable Domains: Business-oriented, one-time payment for lifetime ownership.
Key Benefits of ENS
- Simplified transactions: No more copying/pasting long addresses.
- Enhanced security: Immune to DNS spoofing.
- Web3 integration: Works seamlessly with Ethereum dApps and smart contracts.
- Subdomain flexibility: Create subdomains like
pay.name.ethornft.name.eth.
How Does ENS Work?
ENS uses two Ethereum smart contracts:
- ENS Registry: Stores domain ownership records.
- Resolver: Translates domain names to addresses.
How to Buy an ENS Domain
- Set up an Ethereum wallet (e.g., MetaMask).
- Visit ENS Domains.
- Search for and register your desired name (e.g.,
yourname.eth). - Pay the annual fee (starting at $5/year for 5+ character names).
The ENS Governance Token
- Token type: ERC-20.
- Max supply: 100 million ENS.
Distribution:
- 50% to ENS DAO treasury.
- 25% to early ENS adopters.
- 25% to contributors.
Holders can vote on protocol changes via the DAO.
What Can You Do with an ENS Domain?
- Replace wallet addresses for easier transactions.
- Host decentralized websites (via IPFS).
- Use as a universal Web3 username.
ENS: A Pillar of Web3
ENS bridges the gap between complex blockchain tech and mainstream adoption by simplifying interactions with crypto addresses.

ENS is available on exchanges like Coinbase, Binance, and Uniswap.
How much does an ENS domain cost?
Prices start at $5/year for 5+ character names, plus Ethereum gas fees.
Who created ENS?
Alex Van de Sande and Nick Johnson launched ENS in 2017.
