Ethereum Name Service (ENS) is a decentralized naming protocol that converts long machine addresses like 0x4a2b...f91c into readable names that end in .eth. A wallet address becomes "alice.eth," and that single name can route ETH, tokens across multiple chains, a decentralized website, and a public profile. ENS has run on Ethereum since May 2017, and as of June 2026 more than 2.8 million .eth names are registered, which makes it the closest thing Web3 has to a universal username.
The protocol matters because crypto's biggest usability problem is the address itself. Forty-two hexadecimal characters are impossible to memorize and easy to mistype, and a single wrong character sends funds to a dead end with no recourse. ENS replaces that string with a name you can read, share, and verify, while keeping the underlying security of the Ethereum blockchain. The token that governs the protocol is one part of a system whose real product is identity.
How .eth Names Actually Work
An ENS name is an NFT. When you register "alice.eth," the registrar mints an ERC-721 token that proves ownership, and that token lives in your wallet alongside everything else. Because ownership is an on-chain asset, no company can revoke your name, and you can sell or transfer it like any other NFT.
Two pieces make a name useful, as the ENS protocol documentation lays out. The registry is a single smart contract that records who owns each name and which resolver it points to. The resolver is the contract that actually answers lookups, translating "alice.eth" into an Ethereum address, a Bitcoin address, a content hash for a website, or a text record like an avatar or a Twitter handle. Separating ownership from resolution is what lets a name point to many different resources at once.
Names are hierarchical, the same way DNS works. Whoever owns "alice.eth" automatically controls every subdomain beneath it: "pay.alice.eth," "blog.alice.eth," "vault.alice.eth." Each subdomain can resolve to a completely different address or service, and the owner can hand out subdomains to others without giving up the parent name. Communities use this to issue names like "user.community.eth" to thousands of members from a single root.
Registration runs through a commit-reveal process that takes about three minutes. You submit a hashed commitment, wait roughly sixty seconds so no one can front-run your choice by watching the mempool, then send a second transaction that registers the name. The annual fee depends on length, which is how ENS rations short, valuable names without an auction:
| Name length | Annual fee (paid in ETH) |
|---|---|
| 5+ characters | $5 per year |
| 4 characters | $160 per year |
| 3 characters | $640 per year |
Fees are denominated in USD and settled in ETH, and gas costs are separate and vary with network congestion. Registration data lives on Ethereum, so the underlying records inherit the chain's security guarantees.
What Happens When a Name Expires
ENS names are leases that expire rather than permanent property, and the lifecycle has stages worth understanding before you register or buy one on the secondary market. A registered name that lapses moves through a fixed sequence rather than vanishing instantly.
When the lease ends, the name enters a 90-day grace period during which only the previous owner can renew it at the standard price. Miss the grace period, and the name enters a 21-day Temporary Premium auction: the price starts at a notional $100 million and decays to zero over those three weeks, letting the market discover a fair price for a freshly released name. Once the premium hits zero, the name is available to anyone at the normal annual rate. The full order runs Registered, Expired, Grace Period, Temporary Premium, then Available. Anyone buying a desirable expired name should track exactly where it sits in that cycle, because the premium can swing the cost by thousands of dollars on the same day.
The ENSv2 Pivot to Mainnet
ENS spent much of 2025 building Namechain, a dedicated zero-knowledge rollup meant to house the next version of the protocol and cut the cost of registrations and updates. In February 2026 the team scrapped it, as reported by The Block. The reasoning was practical: Ethereum's gas limit doubled from 30 million to 60 million units during 2025, and the cost of ENS operations on Layer 1 fell by roughly 99%, which erased the main argument for a separate chain.
ENSv2 still shipped, just on Ethereum mainnet rather than on its own L2. The upgrade keeps the goals that justified the rebuild: a hierarchical registry that gives users finer control over names and subnames, lower effective costs, and better interoperability across chains. The team released public alpha versions of a redesigned ENS App and an ENS Explorer so users could test the simplified registration flow and multi-chain name management. The decision drew debate about whether Ethereum's base layer can carry identity at scale, but it removed the execution risk and bridging complexity that a bespoke rollup would have added. For a protocol whose entire value rests on being a trusted source of truth, deploying where the security is strongest carried weight.
The ENS Token and DAO Governance
The ENS token governs the protocol. It launched on November 8, 2021 with a fixed supply of 100 million tokens and no inflation, and the four-year vesting schedule finished in 2025, so the supply is fully unlocked. As of mid-June 2026, roughly 40.4 million ENS circulate, according to CoinGecko market data.
The original distribution put half the supply into the community and a quarter into the people who had already used the protocol:
| Allocation | Share | Purpose |
|---|---|---|
| DAO community treasury | 50% | Protocol development, grants, operations |
| Airdrop to .eth holders | 25% | Reward for early adopters |
| Contributors | 25% | Core team, integrations, advisors |
The token is a governance instrument rather than a fee or staking asset. Holders delegate their voting power, either to themselves or to a representative, and delegates submit and vote on proposals that control the protocol's direction and spending from the treasury. That treasury, funded by registration revenue, is one of the larger war chests in crypto governance, which gives the ENS DAO real resources to fund development independent of token sales. Registration fees flow to the DAO rather than to a private company, aligning the protocol's income with the community that governs it.
Why ENS Became Web3's Default Namespace
The single name doing many jobs is what pushed ENS past a niche tool. One .eth name can serve as a payment address, a login identity across decentralized apps, a handle on social platforms, and the address of a censorship-resistant website hosted on IPFS. Wallets, exchanges, and dapps read ENS natively, so "alice.eth" displays in place of a raw address almost everywhere in the ecosystem.
Adoption compounds because every integration makes the next one more valuable. When a major wallet resolves .eth names, every name becomes more useful, which pulls in more registrations, which gives the next integrator more reason to support the standard. ENS works across more than ten blockchains through multi-coin support, so a single name can hold a Bitcoin address, a Solana address, and an Ethereum address at once. That network effect, combined with the simplicity of one human-readable identity, is why builders increasingly treat ENS as default infrastructure rather than an optional feature.
Frequently Asked Questions
Is ENS the same as buying a domain name?
Not quite. A traditional web domain is leased through a registrar that can suspend or seize it, while an ENS name is an NFT you hold in your own wallet and control directly. Both expire and need renewal, but ENS ownership is enforced by Ethereum rather than by a central authority, which is the core difference.
How much does an ENS name cost?
The annual fee depends on length: names of five or more characters cost $5 per year, four-character names cost $160 per year, and three-character names cost $640 per year, all paid in ETH plus separate gas fees. There is no one-time purchase price for registering an available name, only the recurring lease.
What is the ENS token used for?
The ENS token is a governance token for the ENS DAO. Holders use it to vote on protocol changes and on how the DAO spends its treasury, either by voting directly or by delegating their tokens to a representative. The token does not pay fees or earn staking rewards.
Did ENS really cancel its own blockchain?
Yes. In February 2026 ENS abandoned Namechain, the dedicated Layer 2 it had been building, after Ethereum's gas limit doubled and the cost of ENS operations on mainnet dropped about 99%. ENSv2 launched directly on Ethereum instead, keeping its planned features without a separate chain.
How many ENS names exist?
More than 2.8 million .eth names are registered as of June 2026, and the number continues to grow as wallets and applications adopt the standard as a default identity layer across crypto.
Where ENS Goes From Here
ENS solved a problem every crypto user has and turned the solution into shared infrastructure that the broader ecosystem now depends on. The protocol's reach across wallets, dapps, and more than ten chains, combined with a community treasury large enough to fund years of development, gives it durability that few governance tokens can claim. The ENSv2 move to mainnet signaled a preference for security and simplicity over speculative scaling, a choice that fits a protocol whose job is to be trustworthy.
The open question is value capture. ENS generates real revenue from registrations, but that revenue accrues to the DAO treasury rather than directly to token holders, so the token's worth tracks governance influence and the market's read on the protocol's long-term importance rather than a cash flow. Anyone weighing the token has to separate the health of the naming system, which is strong, from the economics of the token, which are looser.
