The Ethereum Name Service (ENS), the widely recognized decentralized domain protocol, has unveiled an ambitious new chapter in its evolution. At Devcon held in Bangkok, ENS announced plans to launch its own Layer 2 blockchain—dubbed Namechain—marking a pivotal shift toward scaling its infrastructure while reinforcing its role in the growing Ethereum ecosystem. This move aligns with the emerging trend of “one application, one chain,” positioning ENS not just as a naming service but as a foundational pillar in Ethereum’s decentralized future.
Namechain is designed to be a zkEVM-based Layer 2, distinguishing it from other app-specific chains that rely on Optimistic Rollup frameworks like OP Stack. By choosing zero-knowledge technology, ENS aims to deliver faster transaction finality, stronger security guarantees, and seamless compatibility with existing Ethereum tooling—making it highly accessible to developers already familiar with the Ethereum Virtual Machine (EVM).

Seamless Compatibility Between Ethereum Mainnet and Namechain
One of the most critical aspects of the Namechain rollout is cross-layer compatibility. Users who currently own .eth domains on the Ethereum mainnet will retain full functionality when interacting with Namechain. Whether registering, renewing, or managing a domain, the transition will be smooth and non-disruptive.
This backward compatibility ensures that the over 2.3 million registered .eth names—including high-profile ones like vitalik.eth—will continue to operate without migration friction. The ENS team emphasizes that Namechain isn’t replacing the current system but enhancing it, serving as the backbone for future scalability under the broader ENS V2 roadmap.
The development of Namechain reflects a strategic response to rising gas fees and network congestion on Ethereum’s mainnet. While Ethereum remains secure and decentralized, its cost structure can hinder mass adoption for lightweight use cases like domain lookups or profile management. Namechain addresses this by offloading these operations to a purpose-built Layer 2, significantly reducing costs while maintaining trust through cryptographic proofs.
99% Cost Reduction: Can Namechain Drive Exponential User Growth?
According to ENS Labs, the introduction of Namechain could reduce user operation costs by up to 99%. This dramatic decrease applies to common actions such as domain registration, renewal, and metadata updates—making ENS more accessible to everyday users and developers building decentralized applications (dApps) that integrate human-readable addresses.
Lower fees aren’t just about saving money—they’re about democratizing access. With cheaper interactions, new user segments who were previously priced out of the ecosystem may now find it feasible to register their own .eth domains. This opens doors for broader adoption in areas like:
- Web3 social identities
- Decentralized website hosting (.eth sites via IPFS)
- NFT profile picture (PFP) integration
- Cross-platform authentication
Historically, ENS has been more than just a naming service—it has evolved into a digital identity layer for Ethereum. With Namechain, the protocol aims to scale this vision efficiently, enabling millions of micro-interactions without burdening the mainnet.
However, the landscape of Layer 2 and Layer 3 solutions is becoming increasingly fragmented. There are already over 117 active or planned L2/L3 networks, raising concerns about liquidity fragmentation and user experience fragmentation. Unlike projects such as Unichain—which join the OP Stack-powered Superchain for interoperability—Namechain is charting its own path.
This independent approach suggests confidence in ENS’s existing traction and community strength. With over 2000 decentralized applications already integrating ENS functionality, the protocol has established itself as a standard layer in Ethereum’s stack. Building a dedicated chain allows ENS Labs to optimize performance specifically for naming and identity use cases, rather than being constrained by general-purpose rollup designs.

Core Keywords Integration
Throughout this transformation, key concepts remain central to understanding ENS’s strategic direction:
- ENS (Ethereum Name Service)
- Namechain
- Layer 2 blockchain
- zkEVM
- Decentralized identity
- Domain registration
- Scalability solution
- Web3 adoption
These keywords naturally reflect both user search intent and technical relevance. As more individuals seek ways to simplify blockchain interactions, services like ENS—and now Namechain—become essential infrastructure.
Timeline and Development Roadmap
ENS Labs has set a clear target: deploy Namechain on mainnet by the end of 2025. This timeline allows for extensive testing, audits, and community feedback before full release. During this phase, existing ENS functionalities will remain unchanged on Ethereum mainnet, ensuring continuity for current users.
Once live, Namechain will support all core ENS operations with enhanced speed and affordability. Additionally, it may open doors for new features such as:
- Real-time name resolution updates
- On-chain profile metadata storage
- Built-in privacy-preserving lookup mechanisms
- Incentive programs for registrants
The long-term vision includes positioning Namechain as a modular identity layer that other protocols can build upon—further cementing ENS’s role beyond mere domain resolution.
Frequently Asked Questions (FAQ)
Q: What is Namechain?
A: Namechain is a zkEVM-based Layer 2 blockchain developed by ENS Labs to scale the Ethereum Name Service. It aims to reduce costs by up to 99% while maintaining full compatibility with existing .eth domains.
Q: Will I need to migrate my existing .eth domain?
A: No. Existing domains on Ethereum mainnet will work seamlessly with Namechain. There is no required migration process for current users.
Q: Why is ENS building its own Layer 2 instead of using an existing one?
A: By creating a dedicated chain, ENS can optimize performance specifically for naming and identity operations, ensuring better scalability, lower costs, and greater control over upgrades and governance.
Q: Is Namechain part of the Superchain or OP Stack ecosystem?
A: No. Unlike Unichain or other OP Stack-based chains, Namechain is an independent zkEVM rollup built specifically for ENS use cases.
Q: When will Namechain launch?
A: ENS Labs targets mainnet deployment by the end of 2025. Development is ongoing, with testing phases expected throughout 2024 and 2025.
Q: How does Namechain improve Web3 user experience?
A: By drastically lowering transaction costs and speeding up operations, Namechain makes it easier and more affordable for users to manage their digital identities, register domains, and interact with dApps using human-readable names.

Final Thoughts
The announcement of Namechain represents more than just a technical upgrade—it signals a maturation of the Ethereum ecosystem where mature protocols take ownership of their scalability destiny. As “one app, one chain” gains momentum, we may be witnessing the early stages of what some call the Ethereum Federation: a network of specialized, interoperable chains united under shared standards and security principles.
For users, developers, and identity pioneers alike, Namechain offers a compelling glimpse into a future where blockchain interactions are fast, affordable, and intuitive—all powered by a name you can remember.
