Ethereum's Naming Layer Goes Mainnet: ENSv2 Launches as Blockchain Identity Gets a Rebuild
The most-used naming system in crypto just got rebuilt, and almost nobody noticed — because the price chart was louder than the protocol. ENSv2, the new version of the Ethereum Name Service, went live on Ethereum mainnet on October 27, bringing a redesigned ENS App for registering and managing names, a new ENS Explorer for examining name history and configuration, and a revised protocol architecture built around hierarchical registries and more precise permissions. For a network where a human-readable name is often the first thing a new user touches, that is infrastructure, not decoration.
What ENSv2 actually changes
Under the old ENS, permissions were blunt: control over a name tended to mean broad control. Hierarchical registries split ownership and permissions across a name tree, so an organisation can issue subnames and grant limited rights without handing over control of the whole domain. That matters for teams, communities and applications that want to delegate naming — issuing names to members, contributors or customers — while keeping the parent name's rules intact. The new ENS App and ENS Explorer make that structure visible and manageable, rather than something only specialists could reason about.
The deeper point is that raw blockchain addresses are hostile to humans. A long hexadecimal string is easy to mistype and hard to verify. Names anchor a wallet, a profile, a payment destination and a set of permissions in a single readable label. Delegation, narrowing, auditing and revocation all become easier when permissions are attached to a name tree rather than a single blunt key.
The Glamsterdam backdrop: bigger blocks, slower timetable
ENSv2 arrived against a very different Ethereum story. An October 28 explainer set out enshrined Proposer-Builder Separation (ePBS), the Glamsterdam proposal that would move the relays' referee function into the protocol itself. Builders would become official protocol participants, winning bids would be paid even if the block was not delivered, and the consensus block would be separated from the execution payload. A Payload Timeliness Committee of 512 validators would police the 12-second slot, checking that execution payloads arrive on time.
The same proposal sketches a far larger block: a plan to raise the gas limit from 60 million to 200 million, roughly tripling it. That would put more pressure on node operators and on state growth, even as it opens room for more activity per block. It is, in short, a scaling step that trades caution for capacity.
Yet the timetable slipped. On October 22, the Ethereum Foundation postponed Glamsterdam on the Hoodi testnet, which had been scheduled for October 26, and gave no replacement date. The stated issue was EIP-8037 and its interaction with deployed smart contracts. The postponement removed the Amsterdam and Gloas activations and the 200 million gas increase from that testnet step. The concerns were specific to the Hoodi testnet, no mainnet date was given, and there was no action for mainnet users or holders. The contrast is the story of the week: naming shipped on October 27, while the scaling step lost its testnet date.
Why naming is a blockchain story, not a side project
Names are an abstraction layer, and abstraction layers decide who can use a system safely. On-chain identity, delegation, narrowing, auditing and revocation are not cosmetic features; they are how organisations, applications and ordinary users interact with a chain without exposing themselves to constant address risk. ENSv2 does not fix the price, the outflows or the timetable, and it is not a price forecast. Standard Chartered cut its year-end ETH target from $7,500 to $4,000 in June while keeping its 2030 target at $40,000, and ePBS remains a proposal, not a deployed upgrade.
The connection to the Scroll story is instructive: blog 505 argued that lane-picking matters more than slogans, and the same applies here. What is live now is the new ENS App and ENS Explorer and the hierarchical registry design. What waits is Glamsterdam.
Price backdrop: one October 30 reading put ETH at $2,299.14, with a market capitalisation of about $282.70 billion and 24-hour volume of about $11.27 billion, while a morning reading put ETH at $2,228.13 with a market capitalisation of about $272.2 billion. Spot Ether ETFs saw about $220.6 million in outflows in the week of October 19–23, and 322,586 ETH options were due to expire on Deribit on October 30, worth about $777 million.

FAQ
What is ENSv2? ENSv2 is the new version of the Ethereum Name Service, live on mainnet from October 27, with a redesigned ENS App, a new ENS Explorer, hierarchical registries and more precise permissions.
What do hierarchical registries change? They split ownership and permissions across a name tree, so limited subname rights can be granted without handing over control of the whole domain.
What is ePBS? It is the Glamsterdam proposal to bring the relays' referee function into the protocol, make builders official participants, and use a 512-validator Payload Timeliness Committee to police the 12-second slot.
What happened to the Glamsterdam testnet date? It was postponed on October 22; it had been scheduled for October 26 on Hoodi, with EIP-8037 cited, and no replacement date was given. There is no action for mainnet users or holders.
What is the gas-limit plan? A plan to raise the gas limit from 60 million to 200 million, which would put pressure on node operators and on state growth.
Is this the same story as blog 505 or 473? No — blog 505 covers the Scroll pivot and blog 473 covers Vitalik's Layer-2 rethink; this article is about the ENSv2 launch.
Does ENSv2 affect ETH's price? Not directly. ETH was around $2,228–$2,299 in October 30 readings, amid about $220.6 million in spot Ether ETF outflows in the week of October 19–23.
