What is Ethereum Name Service (ENS)?

Ethereum addresses are 42 characters of hexadecimal, which is fine for machines and hostile to people. ENS maps readable names onto them: send to vitalik.eth rather than to a string you have to verify character by character. It also stores profile data, avatars and content hashes, which is why .eth names function as identity rather than only as shorthand.

It works the way DNS works — you register a name, pay annually to keep it, and it resolves. The difference is that ENS registrations are NFTs, tradeable and ownable, and the fees go to a DAO treasury rather than a registrar company.

Cancelling Namechain

ENS Labs began building Namechain in 2024 — a bespoke Layer 2 for ENSv2, intended to make registrations and updates cheap enough that name management stopped being gated by Ethereum gas prices. It was in development for roughly two years.

Then Ethereum solved the problem itself. Scaling work cut ENS registration fees by about 99%, and Fusaka raised the block gas limit to 60 million — double the previous level — with developers targeting 200 million in 2026. The cost case that justified a dedicated chain simply evaporated.

ENS Labs cancelled Namechain and shifted ENSv2 to deploy exclusively on Ethereum mainnet. Abandoning two years of work because the underlying problem was solved elsewhere is an unusually clear-headed decision — most teams ship the thing they built.

What ENSv2 is

An upgrade to the existing protocol rather than a replacement, keeping ENS as Ethereum's identity layer with improved subname handling and registry architecture. Core contributors have confirmed it still launches as planned; only the chain it lives on changed.

• Governance of the ENS DAO, which controls the protocol, the treasury and the fee structure.
• Voting on registration pricing and protocol upgrades.
• Delegation, for holders who want their vote used without voting themselves.

ENS is one of the few crypto protocols with a straightforward, recurring revenue model: people pay annually for names, renewals arrive whether or not the market is up, and the money goes to the DAO. That is closer to a domain registrar's economics than to anything else in the industry.

The gap is the usual one. ENS holds a treasury and earns fees; ENS holders govern rather than receive. There is no buyback and no fee distribution — and ENS's revenue, unlike most protocols', does not collapse with the cycle, which makes the absence of a conversion mechanism more noticeable rather than less.

ENS launched in November 2021 with a supply distributed to users of the protocol, contributors and the DAO treasury, on schedules that have largely completed. The DAO holds a substantial treasury funded by years of registration revenue.

Registration and renewal fees are the income, charged annually per name. That produces something rare in crypto: revenue that recurs because people keep their names rather than because they keep trading.

What the fee cut means

Ethereum's scaling cut ENS registration costs by around 99%, which is gas rather than the protocol's own fee — the amount paid to transact, not the amount paid to ENS. It makes registering vastly cheaper for users without reducing what the DAO earns.

That is straightforwardly good: a lower barrier to registering names, with the same revenue per name. It is also the reason Namechain became unnecessary.

ENS cannot be staked. It is a governance token on Ethereum with no validator set and no protocol yield.

Delegating voting power is the participation mechanism and pays nothing. Anything offering an ENS yield is a lending arrangement.

No revenue accrual to the token

ENS earns recurring fees and holds a large treasury, and holders govern it rather than receive any of it. In a year when Aave built an immutable buyback and Uniswap turned on a fee switch, a protocol with genuinely counter-cyclical revenue and no conversion mechanism stands out.

Names are a small market

Annual fees on .eth names produce steady income and not a large amount of it. ENS is essential infrastructure with modest economics, and the two facts coexist.

Competing name systems

Every chain has its own naming service, wallets increasingly resolve multiple systems, and Unstoppable Domains sells permanent names without renewals. ENS is the standard on Ethereum, which is a strong position and not a universal one.

Squatting and secondary market distortion

Desirable names were registered early by speculators, so the secondary market rather than the protocol captures much of the value in short and memorable names. That is a cost borne by users and not by the DAO.

Two years of work discarded

Cancelling Namechain was the right decision on the merits and it is still two years of engineering that produced nothing shipped. It is worth noting as a cost even when the call was correct.
