The second smart contract is the resolver. The caching time for all records under the domain.The first is an ENS registry recording domains registered on ENS and stores the following information about each of them: Under the hood, ENS is built on two smart contracts. This simplifies the user experience and makes blockchain technology less technical. Instead of using machine-readable albeit inconvenient alphanumeric codes, users can receive any crypto or NFT to a short and easy-to-remember link. One of the main obstacles to the mass adoption of blockchain technologies has been their accessibility and ease of use, which ENS aims to remedy. Moreover, ENS does not have a single point of failure thanks to blockchain technology and is, by design, more censorship-resistant and secure. However, in February 2022, it faced criticism over apparently homophobic tweets by its director of operations.Įthereum Name Service has a one-of-a-kind value proposition due to being the first service that transfers the Domain Name Service to the decentralized Web3.ĮNS is not a company but an open-source project that calls itself “an open public utility that belongs to the company.” Essentially, it aims to become a piece of infrastructure as vital to Web3 as the DNS is to the internet. Like DNS, ENS also uses a system of dot-separated hierarchical names called domains with domain owners fully controlling their subdomains.ĮNS launched with a highly successful retroactive airdrop in November 2021 that rewarded users who had registered addresses before the project launched its token. The goal of Ethereum Name Service is to make the Ethereum-based web easier to access and comprehend for humans - similar to how the Internet’s Domain Name Service makes the internet more accessible. The reverse conversion - associating metadata and machine-readable addresses with human-readable Ethereum addresses - is also possible.

ENS converts human-readable Ethereum addresses like john.eth into the machine-readable alphanumeric codes you know from wallets like Metamask. Ethereum Name Service (ENS) is a distributed, open, and extensible naming system based on the Ethereum blockchain.
