The Taiko tech stack has been officially adopted by ENS for building the ZK Rollup scaling solution on the Ethereum Mainnet for Namechain.

The most widely used domain protocol ENS in the Ethereum ecosystem has officially chosen the Taiko technology stack as its dedicated Decentralization naming service ZK Rollup scaling solution, which serves as the underlying foundation of Namechain.

Namechain will be deployed as a based rollup chain based on the Surge framework launched by Nethermind, while Surge itself is built on top of Taiko technology. This means that one of Ethereum's most critical infrastructure protocols will directly adopt the architecture proposed by Taiko, which has already been successfully run in a production environment.

Why is this important?

ENS covers the human-readable address system of the entire Ethereum ecosystem. By initially choosing a based architecture based on the Ethereum mainnet sequencer, it cast an important vote for what Taiko has been working on: based rollups can already run stably in production environments and will become the next phase of scalability that aligns with Ethereum's values.

Thanks to Taiko's technology, ENS does not need to go through the intermediate process of “gradual decentralization”; Namechain is a fully mainnet-ordered based rollup upon launch.

Speak with “data”, not just stay in “hypothesis”.

Taiko is not just discussing based sorting at a theoretical level, but has actually gone live. Since the mainnet launch in May 2024:

Processed over 50 million transactions with zero downtime

Sub-second pre-confirmation is already running in the production environment, rather than just being written in the white paper.

Ethereum validators efficiently and stably execute packaging and sorting on layer two.

Achieve large-scale performance while maintaining decentralization.

As ENS Labs wrote when deciding to transfer Namechain to Surge: “We have a rare opportunity to skip unnecessary steps in the 'gradual decentralization' path.” They understood that they could build a based rollup using Surge and launch with maximal decentralization from the very beginning. ENS did not just choose an infrastructure that was already operating in production; they chose infrastructure that closely aligned with their core mission.

The actual value brought by Taiko Stack

Built on Taiko technology through Nethermind's Surge framework, Namechain will inherit:

Infrastructure level:

Native Ethereum sorting, without a centralized operator

Launch is Stage 1 rollup, and it has a clear and credible Stage 2 evolution path.

The technology stack that is on par with the Taiko mainnet and has been validated through practical tests.

Fully open-source, trustable and neutral, not controlled by any single company.

Technical breakthrough

ENS needs to provide almost instant name resolution across multiple chains while ensuring strong cryptographic security guarantees. Traditional Layer 2 architectures often force projects to make trade-offs between “Decentralization” and “performance experience,” whereas based rollup breaks this binary choice.

Namechain will leverage the pre-confirmation technology that Taiko has implemented on the mainnet to reduce state updates from “hours” to “seconds,” addressing the critical performance bottleneck that ENS has faced on CCIP-Read for many years. Combined with TEE-supported proof mechanisms and based sequencing, Namechain will be able to provide institutional-level performance and stability under a completely decentralized premise from day one.

All of this is made possible because Taiko is the first team to truly implement pre-confirmation technology “on-chain.”

What changes will it bring?

If core protocols like ENS, which have extremely high reliability requirements and are highly consistent with Ethereum's values, choose to build based on this technology stack, then other applications can certainly adopt it with confidence. Namechain has set a new benchmark for construction that does not sacrifice decentralization.

This deployment also proves that based rollups are not just theoretically superior, but are the pragmatic choice of teams building key infrastructure for Ethereum when it comes to actual implementation.

For teams evaluating rollup solutions, Namechain is a directly referable implementation case; for the entire ecosystem, it proves that the narrative of based rollup is no longer just a vision, but a reality that is already happening and operational.

Next step plan

As Namechain moves from internal testing to gradually advancing to the public testnet (expected in the second quarter of 2026) and the mainnet launch, it will validate on a larger scale what Taiko has already proven: scaling Ethereum does not require compromising on decentralization.

In this collaboration:

Nethermind is responsible for infrastructure operation and maintenance and the Surge framework;

Taiko provides based sequencing technology and pre-confirmation protocol;

ENS brings profound experience in product vision and naming protocols.

This collaboration demonstrates that key mission-level applications can also be built on open-source and open infrastructure, without being locked in by a single centralized provider.
