In the evolving landscape of Web3, decentralized identity and user-friendly naming systems are becoming foundational. Two prominent players in this space are ENS (Ethereum Name Service) and ANS (Arweave Name Service). While both serve as human-readable alternatives to complex blockchain addresses, they differ significantly in design, functionality, and long-term vision. This comparative analysis explores their core features, use cases, market dynamics, and future potential—offering a comprehensive guide for developers, investors, and Web3 enthusiasts.
Understanding ENS: The Ethereum-Based Naming Standard
Launched in 2017 by Alex Van de Sande and Nick Johnson under the Ethereum Foundation, ENS revolutionized how users interact with blockchain addresses. By mapping cryptic hexadecimal strings like 0x... to readable names such as alice.eth, ENS functions as a decentralized DNS for the Web3 world.
Built entirely on smart contracts, ENS operates through three core components:
- Registrar Contract: Manages domain ownership, expiration dates, and resolver settings.
- Resolver Contract: Handles the translation of
.ethnames into blockchain addresses or other resources. - Controller Contract: Governs domain registration, pricing (via oracle-fed rates), and renewal logic.
Each ENS domain is an ERC-721 NFT, enabling full user control, transferability, and trading on platforms like OpenSea. This NFT nature has fueled a vibrant secondary market, where premium domains like paradigm.eth have sold for over 420 ETH.

Key Features of ENS
- Cross-Chain Compatibility: Though built on Ethereum, ENS supports address resolution across multiple blockchains, including Polkadot.
- Decentralized Website Hosting: When paired with IPFS, Arweave, or Skynet,
.ethdomains can host censorship-resistant websites. - Web3 Identity Layer: ENS acts as a DID (Decentralized Identifier), linking wallets, social profiles (e.g., Twitter), and NFTs into a unified digital persona.
Notable adopters include Vitalik Buterin (vitalik.eth) and major brands like PUMA (puma.eth). These domains now appear in mainstream platforms like OpenSea, which allows searching users via .eth handles.
ENS Pricing and Renewal Model
ENS uses a tiered annual fee structure:
- 3-character domains: $640/year
- 4-character domains: $160/year
- 5+ characters: $5/year
Domains must be renewed within 90 days of expiration; otherwise, they enter a descending-price auction. This recurring cost model ensures active usage but introduces risks of loss due to non-renewal—even high-profile domains like eth.link have faced access issues after their owner’s incarceration.
Introducing ANS: The Permanent Alternative on Arweave
While inspired by ENS, ANS (Arweave Name Service) is not merely a clone. Developed by Decent.Land, ANS leverages Arweave’s permanent data storage to offer a unique value proposition: one-time purchase, lifetime ownership.
ANS domains follow the format [name].ar and map Arweave wallet addresses into readable identifiers. Unlike ENS, there are no renewal fees, eliminating the risk of expiration or front-running attacks during renewal periods.
Core Innovations of ANS
- Lifetime Ownership: Pay once, own forever—ideal for long-term identity anchoring.
- Native Ecosystem Integration: Fully supported by everPay, Permaswap, and viewblock.io for seamless transactions and data lookup.
- Token Incentives: The $ANS token (ERC-20) rewards early adopters and participants, fostering community-driven growth.
- ArMoji Support: Users can mint emoji-based subdomains (e.g., 🌟.ar), enhancing personal expression.
With over 1,500 domains minted and 832 token holders, ANS has emerged as one of Arweave’s most active non-financial dApps. Its integration with tools like ar.page allows users to aggregate cross-chain assets and on-chain activity into a single profile.
Functional Comparison: Use Cases and User Experience
| Feature | ENS | ANS |
|---|---|---|
| Base Chain | Ethereum | Arweave |
| Domain Format | .eth | .ar |
| Ownership Model | Annual renewal | One-time purchase |
| NFT Standard | ERC-721 | Custom (Arweave-native) |
| Secondary Market | OpenSea, LooksRare | Permaswap, Uniswap |
| Supported Resolutions | IPFS, Arweave, Swarm, etc. | Arweave-centric |
| Identity Use Case | Web3 profile, DID | Creator identity, permanent ID |
While ENS excels in cross-platform recognition and speculative value, ANS focuses on permanence and ecosystem cohesion within Arweave’s data permanence narrative.

Market Dynamics and Adoption Trends
ENS: A Thriving but Speculative Market
As of 2025:
- Over 2.55 million ENS domains registered
- More than 570,000 unique users
- Monthly registrations peaked at nearly 400,000 in late 2022
Popular categories driving demand include:
- 10K Club (4-digit): High-value numeric domains like
7000.eth(sold for 170 ETH) - Arabic 999 Club (3-digit): Short internationalized names like
٠١٠.eth - Triple Ethmoji: Emoji combinations like 🚀🔥💎.eth
- Chinese Number Domains: Culturally significant numerals (e.g., 88888.ar)
Despite a total market cap near $93 million, ENS suffers from low liquidity (~0.78%), reflecting its use as a long-term identity tool rather than a tradable asset.
ANS: Niche but Growing
ANS remains smaller in scale:
- ~125 AR in total trading volume
- ~5,600 AR in treasury revenue since launch
However, its zero-renewal model appeals to users seeking eternal digital ownership—especially creators building permanent content on Arweave. As UDL (Universal Data License) and other data markets mature, ANS is positioned to become a critical identity layer.
Future Outlook: Beyond Naming Systems
Both ENS and ANS are evolving beyond simple address mapping:
- ENS aims to become a universal DID standard across chains.
- ANS is expanding into the Open Name Service Framework (ONSF), enabling cross-chain identity interoperability.
The ultimate goal? A seamless Web3 experience where your identity follows you across apps, chains, and platforms—without relying on centralized intermediaries.

Frequently Asked Questions (FAQ)
Q: Can I use an ENS domain outside Ethereum?
A: Yes. ENS supports cross-chain address linking (e.g., Solana, Polkadot) and decentralized website hosting via IPFS or Arweave.
Q: Is ANS really permanent? What happens if the project shuts down?
A: Since ANS runs on Arweave—a permaweb storage network—the domain records are stored permanently. Even if the frontend disappears, data remains accessible via blockchain explorers.
Q: Do I need to pay yearly for ANS domains?
A: No. ANS uses a one-time purchase model. Once bought, the domain is yours for life with no renewal fees.
Q: How does $ANS token provide value?
A: $ANS holders receive ecosystem incentives, governance rights (via ANS DAO), and potential revenue sharing from future services.
Q: Can I transfer my ENS domain to someone else?
A: Absolutely. As an ERC-721 NFT, ENS domains can be freely transferred or sold on NFT marketplaces.
Q: Which is better for personal branding—ENS or ANS?
A: ENS currently offers broader recognition due to Ethereum’s dominance. However, ANS provides stronger permanence, ideal for creators prioritizing eternal ownership.
Conclusion: Innovation Over Imitation
While ENS set the benchmark for blockchain naming services, ANS proves that innovation lies not in replication but in adaptation. By aligning with Arweave’s philosophy of permanent data storage, ANS offers a compelling alternative: eternal ownership without recurring costs.
As Web3 matures, diverse naming systems will coexist—just as .com, .org, and .xyz serve different needs today. The key is interoperability. With initiatives like ONSF and EverID underway, the vision of a unified, user-owned digital identity is closer than ever.
The lesson is clear: “Learn from others, but don’t copy.” In the world of decentralized identity, true success comes from building something uniquely sustainable—not just trendy.
