The internet is undergoing a paradigm shift. As centralized platforms face increasing scrutiny over censorship, data privacy, and control, a new wave of startups is building the next iteration of the web: Web3. At the heart of this movement is a push for decentralization, and with it, a new approach to online identity through blockchain-based domains like .eth, .crypto, and .zil.
This article dives into why Web3 startups are embracing decentralized domain names, particularly .eth domains, and what that means for branding, security, and the future of online identity.
What Are Decentralized Domains?
Decentralized domains are not registered through traditional ICANN-accredited registrars. Instead, they exist on blockchain networks like Ethereum or Zilliqa and are managed by smart contracts. Examples include:
- .eth (via Ethereum Name Service)
- .crypto and .zil (via Unstoppable Domains)
These domains aren’t hosted on centralized DNS servers. Instead, ownership is recorded on a blockchain, making them:
- User-controlled (you own the private key)
- Globally resolvable with the right browser or extension
Why Web3 Startups Prefer .eth Domains
1. Ownership and Control
In traditional domains, your registrar can technically suspend or take back your domain based on policies or legal requests. With .eth domains:
- You hold the private keys
- No central authority can revoke ownership
- Your domain lives on the blockchain, not in a centralized registry
This aligns perfectly with Web3’s values: sovereignty, privacy, and censorship resistance.
2. Wallet Integration and Identity
.eth domains can be mapped to Ethereum wallet addresses. This enables:
- Simplified crypto payments (e.g., send ETH to "yourname.eth" instead of a 42-character hex address)
- Unified digital identity across dApps, wallets, and communities
- On-chain reputation tied to a single namespace
For startups building wallets, DeFi tools, or DAOs, this functionality is core to user experience. 3. Community Signaling and Credibility
Using a .eth domain signals membership in the Web3 space. Just as .tech or .ai implies innovation, .eth communicates:
In a world where tribal brand affiliation matters, your domain is part of your identity.
4. Decentralized Hosting Possibilities
While still early, some .eth domains are being paired with IPFS (InterPlanetary File System) to host decentralized websites. This means:
- No single point of failure
- Resistant to takedown requests
- Fully on-chain or hybrid architecture
For example, "yourstartup.eth.link" can point to an IPFS-hosted homepage.
The Technical Landscape: ENS and Its Ecosystem
What Is ENS?
The Ethereum Name Service (ENS) is the primary system for managing .eth domains. Features include:
- Domain registration via auction or fixed pricing
- Mapping to wallet addresses and metadata
- Subdomain delegation (e.g., team.yourstartup.eth)
ENS is governed by a DAO (ENS DAO) that votes on protocol upgrades and policy.
Browser Compatibility
Traditionally, .eth domains don’t resolve in standard browsers without:
- Gateway services like eth.link or eth.limo
However, adoption is expanding. As more browsers integrate ENS natively, these domains will become more accessible.
Challenges and Risks of .eth Domains
While .eth domains offer innovation, they come with trade-offs:
- Limited browser support (though improving)
- No email hosting by default
- Security: Loss of private keys = loss of domain
- No traditional DNS records (without third-party gateways)
- Legal ambiguity: Ownership disputes and trademark conflicts are harder to resolve on-chain
For high-stakes businesses, these limitations may require hybrid solutions.
The Future: Interoperability and Adoption
The gap between Web2 and Web3 is narrowing. New tools are emerging to bridge traditional domains with blockchain domains:
- Gateways that map .eth domains to DNS
- Wallets that auto-resolve blockchain identities
- ENS integrations with social media, chat apps, and marketplaces
This hybrid model lets startups benefit from decentralization while maintaining usability.
How Traditional Domain Registrars Fit In
Some registrars, like NameSilo, are watching this space closely. While blockchain domains don’t currently route through ICANN infrastructure, there’s growing interest in:
- Offering ENS-compatible features
- Educating users on decentralized vs. traditional DNS
- Helping projects secure both .com and .eth versions for brand protection
In the future, hybrid registration and DNS integration may become standard.
Final Thoughts
For Web3 startups, .eth domains offer more than novelty. They are strategic assets that align with decentralized values, integrate with wallets and dApps, and serve as a badge of blockchain-native identity.
While they don’t yet replace traditional domains, they complement them in powerful ways. The smart move for founders? Secure both a traditional domain (like .com or .xyz) for accessibility and a .eth domain for Web3 identity. The decentralized web is coming, and with it, a new set of tools to own your presence online.
At NameSilo, we stay at the forefront of domain innovation. While we specialize in traditional domains, we also help founders navigate the evolving world of decentralized naming. Lock in your brand with a .com or .xyz, then explore Web3 options with confidence.
