Ethereum Name Service (ENS) is revolutionizing how users interact with blockchain addresses by replacing complex, error-prone strings of characters with simple, human-readable names like yourname.eth. Built on the Ethereum blockchain, ENS functions as a decentralized naming system that simplifies transactions, improves security, and enhances user experience across Web3 applications.
This guide explores the core mechanics of ENS, its unique value proposition, tokenomics, and practical use cases—while addressing common questions and opportunities in today’s evolving decentralized ecosystem.
What Is Ethereum Name Service (ENS)?
Ethereum Name Service (ENS) is a decentralized, open, and extensible naming protocol built on the Ethereum blockchain. Its primary function is to translate long, complicated wallet addresses—such as 0x4bbeEB066eD09B7AEd07bF39EEe0460DFa261520—into easy-to-remember domain names like alice.eth.
This process works both ways:
- Forward resolution: Converts
bob.ethinto a valid Ethereum address. - Reverse resolution: Assigns a human-readable name to an Ethereum address, making it easier to identify when sending funds or interacting with dApps.
ENS operates similarly to the traditional Domain Name System (DNS) used on the internet but with one key difference: full user ownership. Unlike centralized domains that can be censored or seized, ENS domains are stored as NFTs in users’ wallets, giving them complete control over their digital identity.
Domains are structured hierarchically using dot-separated levels (e.g., subdomain.maindomain.eth), where owners can create and manage subdomains freely. This makes ENS not just a naming tool but also a foundational layer for decentralized identity and website hosting via IPFS integration.

Core Features That Set ENS Apart
What makes ENS truly stand out in the Web3 space?
1. User-Controlled Ownership
Once you register an ENS name, it resides in your wallet as a non-fungible token (ERC-721). No third party can take it away, freeze it, or modify it without your permission.
2. Cross-Application Compatibility
ENS names work across hundreds of dApps, wallets (like MetaMask), and services. You can use your name.eth for crypto payments, decentralized websites, NFT profiles, and even email alternatives.
3. Metadata Management
Beyond wallet addresses, ENS supports storing additional metadata such as:
- Avatars
- Profile descriptions
- Social media links
- Public keys for encryption
This turns an ENS domain into a portable digital identity usable across platforms.
4. Decentralized Governance
ENS is governed by its community through the ENS DAO (Decentralized Autonomous Organization). Holders of the ENS token vote on proposals related to funding, upgrades, and policy changes—ensuring long-term transparency and decentralization.
ENS Tokenomics: Supply and Distribution
The ENS token is an ERC-20 utility and governance token central to the network's decision-making process.
Total Supply
There are exactly 100 million ENS tokens in existence, with no plans for further minting.
Circulating Supply
As of 2025, approximately 80% of the total supply is in circulation, with the remainder allocated to contributors, developers, and future incentives.
A significant portion of tokens was distributed via a retroactive airdrop in November 2021. Early adopters who registered ENS domains before October 31, 2021, received tokens based on usage history—a move praised for rewarding genuine community members.
Notably, the project faced controversy in early 2022 when a team member’s past social media activity sparked backlash. However, the DAO responded swiftly with governance reforms and increased transparency measures.
How Secure Is the ENS Network?
Since ENS runs entirely on the Ethereum blockchain, its security model inherits Ethereum’s robust proof-of-stake consensus mechanism. All domain registrations, transfers, and updates are recorded immutably on-chain.
Smart contracts powering ENS have undergone multiple audits by leading firms like OpenZeppelin and ConsenSys Diligence. Additionally:
- The registry contract is designed to be minimal and upgrade-resistant.
- Users retain full custody of their domains at all times.
- No central entity controls the system.
While phishing risks exist (e.g., fake domains like appIe.eth instead of apple.eth), user education and browser integrations help mitigate these threats.

Where Can You Buy ENS Tokens?
ENS tokens are widely available on major cryptocurrency exchanges including OKX, Coinbase, Kraken, and Uniswap. To purchase ENS:
- Set up a compatible wallet (e.g., MetaMask).
- Deposit ETH or stablecoins.
- Search for “ENS” and place your order.
Once acquired, you can stake or delegate your ENS tokens to participate in governance proposals—even if you don’t own a domain.
Frequently Asked Questions (FAQ)
What can I do with an ENS domain?
You can use it to receive cryptocurrencies, host decentralized websites, link social profiles, verify identity in dApps, and build a persistent Web3 presence.
How much does an ENS domain cost?
Registration fees vary by name length:
- 5+ characters: ~$5/year
- 4 characters: ~$160/year
- 3 characters: ~$640/year
Prices are paid in ETH and subject to change based on demand.
Can I sell my ENS domain?
Yes. Since each domain is an NFT, you can list it on marketplaces like OpenSea or Blur for resale.
Is ENS compatible with other blockchains?
Currently, ENS primarily supports Ethereum and L2 networks like Optimism and Arbitrum. Cross-chain compatibility is expanding through bridges and Layer 2 integrations.
How is ENS different from traditional domains?
Traditional domains (e.g., .com) are centrally managed and require renewal through registrars. ENS domains are self-owned NFTs on Ethereum—no intermediaries involved.
Does owning an ENS give me IP rights?
No. Owning brand.eth doesn’t grant legal trademark rights. Brands should register defensively to protect their identity.

Final Thoughts: The Future of Digital Identity
Ethereum Name Service isn’t just about simplifying crypto addresses—it’s laying the foundation for a new kind of digital identity. As more services adopt decentralized logins, social layers, and wallet-based authentication, having a memorable .eth name becomes increasingly valuable.
With strong adoption, active governance, and seamless integration across wallets and dApps, ENS stands at the intersection of usability and decentralization—a critical piece of infrastructure for the next generation of the internet.
