Ethereum Name Service

Ethereum Name Service (ENS) is a distributed, open naming system on Ethereum that maps human-readable names like 'alice.eth' to machine-readable identifiers, wallet addresses, other crypto addresses, content hashes and metadata. It also supports reverse resolution, tying canonical names back to addresses. Structurally it echoes the internet's DNS, using dot-separated hierarchical domains where a domain owner controls its subdomains, but top-level domains such as '.eth' are governed by on-chain registrar smart contracts rather than centralized registries.

ENS as on-chain identity: the investment case

ENS names are registered as NFTs, and the ENS token is a governance asset directing the protocol's treasury and parameters, while registration and renewal fees give the system a real revenue base tied to genuine usage. The bull case is that ENS is the entrenched standard for on-chain identity, a natural primitive as wallets and apps proliferate. The bear case is that demand is tied to crypto adoption cycles, renewals can lapse, competing naming systems exist, and a governance token does not automatically capture fee revenue for holders. ENS suits those betting on digital identity as durable infrastructure rather than seeking near-term cash flow.

1. 1. Choose an exchange. Pick a reputable exchange that lists ENS — among the venues we rate highest are Binance, OKX and Kraken.
2. 2. Create & verify your account. Register, enable two-factor authentication, and complete identity verification (KYC).
3. 3. Deposit funds. Add money by bank transfer, card, or a stablecoin, depending on what the exchange supports in your region.
4. 4. Buy ENS. Search for ENS, choose a market or limit order, enter your amount, and confirm.
5. 5. Secure your coins. For long-term holdings, withdraw ENS to a self-custody wallet you control rather than leaving it on the exchange.
