Ethereum Name Service (ENS) is the decentralised naming system that lets a string like alice.eth stand in for a long, error-prone hexadecimal wallet address, and ENS is its governance token.
What ENS does
ENS domains are registered on-chain as NFTs, giving holders provable, transferable ownership rather than the leased, revocable arrangement typical of traditional domain registrars. Once registered, a .eth name can resolve to a wallet address, a decentralised website, a Twitter handle or other metadata, and it's now widely supported across wallets and exchanges as a human-readable alternative to pasting raw addresses — a real usability fix for one of crypto's oldest pain points, mistyped or copy-pasted wrong addresses.
The project was built by ENS Labs (originally True Names Ltd), led by Nick Johnson, and launched its governance token via a November 2021 airdrop to existing domain holders, who were rewarded based on registration history. ENS holders now govern the ENS DAO, voting on protocol upgrades, treasury spending and technical direction, including expanding resolution beyond Ethereum mainnet to layer 2s via cross-chain resolution standards. Annual renewal fees, paid in ETH, fund a treasury used for public-goods grants and ecosystem development.
Risks worth knowing
ENS's core registration business is inherently cyclical — new domain registrations and renewals track broader crypto adoption and speculative interest, so protocol revenue rises and falls with the market rather than growing steadily. Competition has also emerged from other naming systems, including Unstoppable Domains and chain-specific alternatives like Base's basenames, fragmenting the human-readable-address space rather than consolidating around one standard.
The ENS token itself carries governance rights but, as things stand, no direct claim on protocol fee revenue — there's no active 'fee switch' routing registration income to token holders, so ENS's price is driven more by governance-utility speculation and ecosystem growth than by demonstrated cash flow. Domain squatting and speculative flipping of desirable short names is also a recurring feature of the market, adding volatility unrelated to the protocol's underlying utility.
