Ethereum Name Service is the first open-source, public blockchain domain protocol on Ethereum. ENS maps human-readable domain names like chad.eth to crypto wallet addresses, content hashes and metadata, making them easy to share, use and remember. ENS is the name and ticker symbol of Ethereum Name Service's native governance token.
When you purchase a domain from ENS, you receive a tradable ERC721 NFT contract with your chosen domain name for a fixed period. Renewal fees are applicable on a yearly basis.
With an ENS name, you can access crypto wallet addresses and receive cryptocurrencies and NFTs through your .eth username. ENS also supports traditional domain names such as .com, .org, .io, .app, .xyz and .art.
If you own an ENS domain, you can also create and configure subdomains. For example, if you own bob.eth, you can create crypto.bob.eth. Additionally, the InterPlanetary File System (IPFS) network allows you to launch censorship-resistant decentralized websites with ENS. To do so, upload your website to IPFS and access it with your ENS name.
Ethereum Naming Services has over 463 integrations, including wallets, apps and browsers. These integrations include trusted names like Coinbase, Trust Wallet, Uniswap, Etherscan, Aave, Brave, Cloudflare and Metamask.
ENS is an ERC-20 governance token of the ENS DAO. ENS token holders can vote on protocol proposals. They can also delegate their voting power to other ENS community members.
ENS has a total supply of 100 million tokens. 50% is allocated to the ENS DAO community treasury, 10% was distributed at launch and the remaining supply is scheduled to be unlocked over four years. The DAO plans to spend these funds for growth and development initiatives like grants, hackathons, meetups and more.
From the remaining supply, 25% of the tokens were airdropped to ENS users who own or have owned .eth second-level domain. This airdrop drew a lot of media attention to the protocol, thereby causing a positive action for ENS price. Another 25% was given to individuals and organizations who contributed significantly to ENS. These include the core team at True Names LTD, external contributors, select integrations, translators, launch advisors, root key holders and over 450 active members in the ENS Discord server, among others.
ENS charts are dependent on the adoption of the Ethereum Name Service. ENS claims they are the most widely integrated blockchain naming system, with 652,000 names registered.
Ethereum Naming Service was founded in early 2017 by Nick Johnson at the Ethereum Foundation, a non-profit organization that supports Ethereum. After a year, ENS was incorporated as True Names Limited, a Singapore-based non-profit. True Names LTD oversees ENS development.
The project has received financial support from Ethereum Foundation, Chainlink, Protocol Labs and Ethereum Classic Labs.
ENS has also collaborated with Cloudflare to develop Coudfare's native ENS and IPFS gateway for eth.link.
The architecture of Ethereum Name Service consists of two smart contracts called the registry and resolvers.
Registry is a single smart contract that maintains a list of all domains and subdomains. The smart contract stores the domain owner's name, the domain's resolver and the time-to-live of all records under the domain.
On the other hand, resolvers are smart contracts that map ENS domain names with their respective resources, such as cryptocurrency addresses and content hash.
When you try to find an Ethereum address registered as an ENS name, such as bob.eth, the registry is asked which resolver is responsible for bob.eth. Then the query is sent to the resolver of bob.eth. The resolver then maps bob.eth with the associated Ethereum address.
You can buy ENS from OKX exchange. OKX offers the ENS/USDT and ENS/USDC trading pair. Alternatively, you can buy ENS directly with fiat or convert your crypto to ENS.
Before you begin trading with OKX, you need to create an account. To buy ENS with your preferred fiat, click "Buy with card" under "Buy Crypto" on the top navigation bar. To trade ENS/USDT or ENS/USDC, click "Basic Trading" under "Trade". Under the same tab, click "Convert" to convert crypto to ENS.
