Ethereum Name Service (ENS) is revolutionizing the way users interact with blockchain addresses by replacing complex hexadecimal strings with human-readable names—like alice.eth. As decentralized identity and Web3 adoption grow, ENS has emerged as a critical infrastructure layer on the Ethereum network. This article dives into what ENS is, how it works, its market performance, and why it matters in today’s evolving digital ecosystem.
Whether you're exploring ENS for the first time or considering its long-term potential, this guide delivers accurate, up-to-date information while addressing common questions about pricing, utility, and future outlook.

What Is Ethereum Name Service (ENS)?
Ethereum Name Service (ENS) is a decentralized domain name system built on the Ethereum blockchain. It allows users to register and manage easy-to-remember domain names that map to cryptocurrency wallets, websites, content hashes, and metadata. Instead of sending funds to 0xAbC...123, you can simply use yourname.eth.
ENS operates similarly to traditional DNS (Domain Name System), but with key differences:
- Decentralized ownership: No central authority controls ENS domains.
- User-controlled: Registrants fully own their domains via smart contracts.
- Censorship-resistant: Once registered, names cannot be taken down by third parties.
The native token of the ENS ecosystem is also called ENS, used primarily for governance within the ENS DAO (Decentralized Autonomous Organization). Holders can vote on proposals related to protocol upgrades, funding allocations, and policy changes.
Core Features of ENS
- Human-readable addresses: Simplify wallet interactions.
- Cross-application compatibility: Works across wallets, dApps, and browsers.
- Permanent ownership: Domains are yours as long as you renew them annually.
- Open and extensible: Developers can build on top of ENS using open standards.
How Does ENS Work?
At its core, ENS consists of two smart contracts on Ethereum:
- Registry Contract: Maintains a list of all domains and subdomains, along with ownership and resolver information.
- Resolver Contract: Translates domain names into machine-readable data (e.g., wallet address or IPFS hash).
To register a domain like mywallet.eth, users participate in an auction-like process through the .eth registrar, which uses a reverse auction mechanism to ensure fair distribution. After registration, users must pay an annual renewal fee in ETH to retain ownership.
Names can be permanent or short-term depending on length:
- 5-character or longer: Annual fee (~$5/year)
- 3–4 characters: Higher annual cost (~$160/year)
- 2-character names: Extremely rare and expensive

ENS Tokenomics and Market Data
While the exact real-time price fluctuates based on market conditions, the ENS token plays a vital role beyond speculation—it powers decentralized governance. Here's a breakdown of key metrics (note: values are illustrative based on typical 2025 trends):
- Total Supply: 100 million ENS
- Circulating Supply: Approximately 36.49 million (36.49%)
Token Allocation:
- 50% distributed to past contributors and users
- 25% to the DAO treasury
- 25% reserved for future team and community incentives
The token does not fuel transaction fees; instead, ETH covers all operational costs such as domain registration and renewals.
Why Market Cap Isn't Fully Reflective
Unlike traditional cryptocurrencies where supply directly impacts price, ENS’s value lies more in its utility and adoption than pure trading volume. Many holders are long-term believers who use their domains actively rather than trade tokens frequently.
Still, price movements often correlate with broader Ethereum ecosystem growth, NFT trends, and Web3 identity developments.
Use Cases of ENS Domains
ENS isn’t just about simplifying crypto transactions—it enables a wide range of applications across the decentralized web.
1. Simplified Wallet Addresses
Instead of sharing long wallet strings, users can send and receive crypto using .eth names. Most major wallets—including MetaMask and Rainbow—support ENS natively.
2. Decentralized Websites
By linking an ENS name to an IPFS (InterPlanetary File System) hash, users can host censorship-resistant websites without relying on centralized servers.
3. Identity Across dApps
ENS serves as a foundational identity layer. Platforms like OpenSea, Gitcoin, and Snapshot use ENS names to represent user profiles, enabling seamless cross-platform recognition.
4. Subdomain Delegation
Organizations can create custom subdomains (e.g., payments.company.eth) for internal use or customer-facing services.
Frequently Asked Questions (FAQ)
Q: Can I buy an ENS domain with any cryptocurrency?
A: No. All registrations and renewals require payment in ETH only, as transactions occur directly on the Ethereum blockchain.
Q: Are ENS domains NFTs?
A: Yes. Each .eth domain is represented as a non-fungible token (NFT) under the ERC-721 standard, meaning it’s unique, transferable, and tradable on NFT marketplaces.
Q: What happens if I don’t renew my ENS domain?
A: After expiration, there’s a 90-day grace period during which you can renew at the normal rate. Beyond that, the domain becomes available for others to register.
Q: Is ENS compatible with other blockchains?
A: Currently, ENS is built exclusively on Ethereum. However, cross-chain bridges allow indirect usage on Layer 2 networks like Arbitrum and Optimism.
Q: Who governs the ENS protocol?
A: The ENS DAO, governed by ENS token holders, makes decisions about upgrades, funding, and strategic direction.
Q: Can I sell my ENS domain?
A: Absolutely. Since domains are NFTs, they can be listed on platforms like OpenSea or Sudoswap for resale—some premium names have sold for tens of thousands of dollars.

The Future of ENS and Web3 Identity
As digital ownership evolves, ENS is positioned at the forefront of decentralized identity solutions. With growing interest in self-sovereign identity—where individuals control their personal data without intermediaries—ENS offers a practical implementation already in use by millions.
Future developments may include:
- Integration with decentralized social networks
- Support for verifiable credentials (e.g., education or employment proof)
- Expanded multichain functionality
- Enhanced privacy features
Its role extends beyond convenience; it represents a shift toward user empowerment in an increasingly digital world.
Final Thoughts
Ethereum Name Service (ENS) is more than just a naming tool—it's a cornerstone of Web3 infrastructure. By transforming complex addresses into simple names, it improves usability, security, and interoperability across decentralized applications.
Whether you're a developer building the next dApp, an investor tracking emerging trends, or simply someone curious about blockchain innovation, understanding ENS is essential.
As adoption grows and new use cases emerge, ENS will continue to play a pivotal role in shaping how we identify ourselves and interact online—without relying on centralized authorities.
