ENS Domain Explained 2024: What is ENS and How To Buy One

Ever heard of ENS domain? Or Ethereum Name Service?

Well, those active in the crypto space will be familiar with the hassles of using long wallet address. Basically, every time you want to make a crypto transaction, you have to use your wallet address—a long string of numbers and letters. These long addresses are not only confusing but have also resulted in losses due to errors and scams. This is where the ENS domains make things a bit simpler.

What is an ENS?

Ethereum Name Service (ENS) is a “distributed, open, and extensible naming system based on the Ethereum blockchain”. Put simply, it allows users to generate a simple and easy-to-remember name for all their wallet addresses and decentralized websites.

To illustrate, instead of a confusing address like “0xAB25FF3F5A8S18699855668A2ADA096545FBA2D695E”, you can simply use “Jane.eth”. Jane.eth will be your ENS domain where you can get all your tokens and NFTs. You can buy and manage your own ENS domains, making blockchain transactions much easier.

How Does ENS Work?

ENS operates similarly to Domain Name Service (DNS) on the Internet. A DNS transforms IP addresses, a string of numbers, into human-friendly domain names called a URL. Similarly, ENS converts machine-readable addresses to human-readable names.

To understand how ENS operates, you have to first understand what it is made of. Essentially, ENS includes two Ethereum smart contracts:

  • The first, called ENS registry, records all the domain names. Each domain name consists of the owner’s details, the “caching time-to-live” of all the domain records, and the link to the resolver.
  • Now, a resolver is the second smart contract responsible for translating names into addresses and vice versa. Essentially, the resolver matches each domain to its user, address, IPFS content hash, or website. As the domain name system uses the ERC-721 standard, you can sell the domain to others, just as with NFTs.

Components of the domain system

What can you do with ENS domains?

Basically, ENS domain helps users to change their long, illegible wallet addresses into easy-to-remember names. Think of this as saving someone’s number on your phone using their name. You don’t have to dial the number each time to call the person – you simply have to search for their name. In the same way, ENS’s makes blockchain transactions within the Ethereum ecosystem much simpler, with a lower chance of making errors.

Once you get your domain, you can link it to your public wallets, websites, smart contracts, or transactions. As an ENS domain owner, you can also get other subdomains to link to other data. For example, email.jane.eth or website.jane.eth.
