Executive Summary
The Ethereum Name Service (ENS) has established itself as a foundational layer of Web3 infrastructure, transforming how users interact with blockchain technology. By converting complex hexadecimal addresses into human-readable names, ENS bridges the usability gap that has long challenged mainstream crypto adoption. As of April 2025, ENS boasts over 2 million registered domains, 745 integrations across the Web3 ecosystem, and nearly 883,000 unique owners. This analysis examines ENS's architecture, governance system, market performance, real-world applications, and future potential as both a utility service and investment opportunity.
What Is Ethereum Name Service (ENS)? Understanding the Web3 Domain Revolution
Launched in May 2017, the Ethereum Name Service represents a decentralized approach to domain naming on the blockchain. Similar to how the Domain Name System (DNS) converts website addresses into IP numbers, ENS transforms machine-readable blockchain addresses (like 0x1234abcd5678efgh) into user-friendly names (such as "alice.eth").
Initially developed under the Ethereum Foundation's umbrella, ENS became an independent project in 2018 under the leadership of Nick Johnson, a former Google and Ethereum Foundation engineer. The project operates as a community-driven non-profit with support from prominent organizations including the Ethereum Foundation, Binance_X, Chainlink, Ethereum Classic Labs, and Protocol Labs.
Unlike traditional domain services, ENS leverages Ethereum's blockchain to create a naming system that is:
- Decentralized: No central authority controls the registry
- Secure: Protected by Ethereum's blockchain security
- Transparent: All operations are visible on the public ledger
- Censorship-resistant: Names cannot be arbitrarily seized or modified
These properties align with Web3's core principles of user sovereignty and decentralization, positioning ENS as essential infrastructure for the next generation of internet applications.
How ENS Works: Technical Architecture Explained
ENS operates through an elegant two-component system that handles both ownership records and the resolution process:
The Registry: Ownership and Control
At the heart of ENS lies the Registry, a smart contract that maintains a definitive list of all domains and subdomains in the system. For each domain, the Registry stores three critical pieces of information:
- The owner of the domain
- The resolver associated with the domain
- Time-to-live (TTL) settings for caching
This contract tracks domain registrations and provides owners with complete control to transfer or reclaim their domains as needed. The ownership model ensures that domain control remains firmly in the hands of users rather than centralized entities.
Resolvers: Translating Names to Resources
Resolvers are specialized smart contracts responsible for the actual translation between human-readable names and various resource identifiers. They handle the mapping for multiple data types, including:
- Cryptocurrency addresses across different blockchains
- Content hashes for decentralized websites
- Text records for metadata like email addresses and social media handles
- Other custom resource types
This resolver architecture provides flexibility, allowing domain owners to configure their names to point to virtually any digital resource.
The Naming Hierarchy
ENS implements a hierarchical naming structure similar to traditional DNS:
- Top-level domains (like .eth) are governed by registrar contracts
- Second-level domains (like alice.eth) are registered by users
- Subdomains (like wallet.alice.eth) can be created by domain owners
The .eth registrar is permanent and handles the allocation of all .eth names through a systematic process designed to prevent squatting and ensure fair distribution.
Names are processed using the namehash algorithm, which converts domain strings into unique 256-bit cryptographic hashes. This enables efficient lookup and guarantees each domain has a singular, verifiable identifier within the system.
Registering an ENS Domain: Process, Pricing, and Considerations
Securing an ENS domain is straightforward through the ENS Manager App, though several factors affect cost and availability:
Registration Steps
- Connect wallet and search: Users connect a Web3 wallet like MetaMask and search for their desired .eth name
- Select registration period: Choose how many years to register the domain (minimum one year)
- Request to register: Initiate a transaction that hashes the name with a secret key to prevent front-running
- Wait period: After a 60-second protection period, complete the registration within 24 hours
Pricing Structure
ENS domains are priced based on character length, with annual fees structured as follows:
- 5+ characters: $5 per year
- 4 characters: $160 per year
- 3 characters: $640 per year
This tiered pricing reflects the scarcity and desirability of shorter names while keeping longer domains affordable for most users.
Additional Costs
Beyond the base registration fee, users should consider:
- Gas fees: Ethereum network transaction costs, which vary based on network congestion
- Renewal fees: Domains must be renewed before expiration to maintain ownership
- Setup costs: Additional transactions may be required to configure resolvers or records
It's worth noting that the name is not reserved during the 24-hour registration window, making prompt completion important for securing desirable domains.
ENS Token and Governance: The Community-Driven DAO
In November 2021, ENS launched its governance token ($ENS), transforming the project into a fully community-controlled protocol:
Token Distribution
The ENS token has a fixed total supply of 100 million tokens, allocated as follows:
- 50% to DAO Community Treasury: 10% released at launch, with the remainder vesting linearly over four years
- 25% to Airdrop Recipients: Distributed to early .eth domain holders who registered before October 31, 2021
- 25% to Team and Contributors: Supporting ongoing development and operations
As of April 2025, approximately 35.83 million tokens are in circulation, creating a market capitalization of around $514.52 million.
The ENS DAO
Token holders govern the protocol through a decentralized autonomous organization (DAO), voting on crucial aspects of the service including:
- Registration pricing and policy
- Price oracle settings
- Treasury fund allocation
- Protocol upgrades and improvements
The governance model encourages delegation, allowing token holders to either vote directly or delegate their voting power to trusted community leaders. This system, inspired by Gitcoin's governance approach, balances broad participation with expertise.
Governance Process
ENS proposals follow a structured path:
- Discussion: Ideas are presented and refined on the ENS forum
- Snapshot Vote: Off-chain voting to gauge community sentiment
- On-chain Vote: Formal voting through Tally or Agora for binding decisions
The DAO is supported by a rotating Steward Council, a diverse group of token holders serving six-month terms who review initiatives and ensure thoughtful, community-driven decision-making.

Real-World Applications: How ENS Is Being Used Today
ENS has evolved beyond simple domain resolution to enable numerous practical applications:
Simplified Cryptocurrency Transactions
Perhaps the most immediate benefit is the ability to send cryptocurrencies, tokens, or NFTs to human-readable names rather than error-prone hexadecimal addresses. Users can simply enter "rick.eth" instead of "0x71C7656EC7ab88b098defB751B7401B5f6d8976F," dramatically reducing the risk of transaction errors.
Web3 Identity and Profile Management
ENS names function as comprehensive digital identities, storing metadata including:
- Email addresses
- Social media handles
- Avatar images
- Website links
- Personal descriptions
This creates a universal Web3 username that works across platforms and applications, simplifying user recognition and interaction throughout the decentralized ecosystem.
Decentralized Website Hosting
ENS names can point to content hosted on decentralized storage systems like IPFS (InterPlanetary File System), enabling fully decentralized websites. This approach eliminates traditional web hosting vulnerabilities like server downtime and censorship risks.
Flexible Subdomain Management
Domain owners can create and manage subdomains for:
- Organizing personal resources (wallet.alice.eth, nft.alice.eth)
- Building project ecosystems (docs.project.eth, app.project.eth)
- Selling or distributing to other users
This hierarchical structure adds significant flexibility and organizational capabilities.
Cross-Platform Authentication
ENS supports the "Sign In With Ethereum" (SIWE) standard, providing a unified login system across decentralized applications. This simplifies user experience by eliminating the need for multiple accounts across different services.
Document and Ownership Verification
Emerging use cases include verifying document authenticity and ownership claims through ENS records, potentially streamlining legal and administrative processes in the future.
