What Is Ethereum Name Service? Why Is It Important For Web 3.0?


30 May 2022

As more people start using blockchain technology, they will want to interact with others on social networks. You will want to connect with your friends on web 3.0 in the same manner that you would add a contact to your phone or follow them on social media. In other words, you will want to do both. 

This objective, however, is made more difficult by the fact that wallet addresses may be very long, convoluted, and laborious to type. This concern is going to be addressed by Ethereum Name Service ENS, which offers a search service in addition to name service. In addition to this, it makes it possible for users to make full use of web 3.0 by assigning.ETH domain names to their websites. 

But what exactly is Ethereum Name Service, and how does one go about registering a username or domain ending in.ETH? What is an ENS token? And whether is ENS crypto a good investment? All information will be clarified and shown to you in this bePAY insightful post.

What Is Ethereum Name Service?

Crypto addresses are lengthy sequences of numbers and letters meant for computers to read. These lengthy addresses have caused confusion and even financial loss.

The Ethereum Name Service, or ENS, is a distributed platform built on the Ethereum blockchain that gives an easy solution to lengthy and complicated crypto addresses; a URL that symbolizes a cryptographic address, similar to a domain name or email.

ENS substitutes the lengthy public address that crypto users are used to with a simple moniker that is easy to read and remember. Something complicated, such as “8e866f012fb8fb…” is simplified to “Alex.eth”

ENS employs the same principle as the Domain Name Service (DNS), which maps simple website names to their corresponding IP addresses, to make cryptographic addresses simple to read and publish.


What is Ethereum Name Service?

ENS consists of two Ethereum smart contracts: the ENS registry, which stores domain names; and the Resolver, which converts domain names to machine-readable addresses and vice versa.

This is how the ENS motivates users:

  • Users are scrambling to protect their ENS domains before they become inaccessible, as they did in the early days of DNS.
  • ENS supports .com, .org, .io, and  .app, among others.
  • The browsers Brave, Opera, Status (mobile), MetaMask Mobile (mobile), and Puma currently support ENS.

What Is ENS Token?

The Ethereum blockchain was used to produce the ENS governance token. In the same way that other crypto tokens are exchanged by investors, the ENS token serves a particular purpose in the ENS community. Members of the Decentralised Anonymous Organisation (DAO) utilize their tokens to propose improvements they want to see implemented in the organization.

If you’re interested in the ENS Constitution, for example, you’ll have the opportunity to vote on it later this year. One vote may be cast for each token. If 67% of those voting “yes” on a constitutional amendment say so, the amendment is approved.


What is ENS token?

For a user to propose a new idea to the ENS community, they will require 100,000 tokens of support. The DAO allows users to vote on a wide range of issues, including

  • Web3 development grants that may be funded by designating a part of the liquid token pool for this purpose.
  • Appointments and removals of directors, members, and supervisors are examples of off-chain social ideas.
  • Amendments to the ENS constitution that modify the organization’s purpose.

Architecture Behind Ethereum Name Service

ENS originated as a profitable option for novices to simplify the crypto and DeFi industries. It let users generate universal monikers for all their public addresses and decentralized accounts. 

Instead of employing an unintelligible string of keys for many crypto addresses, customers may depend on a single ENS Ethereum domain. ENS aims to serve as the naming protocol for decentralized internet services by providing portable and compatible Web 3.0 usernames across various decentralized applications and blockchains.

Essentially, ENS functions by mapping lengthy public addresses and replacing them with concise, easily-read names. It is possible to get a deeper understanding of how Ethereum Name Service operates by examining its architecture.

The ENS is a decentralized, open technology built on the Ethereum blockchain that functions as an expandable name system. ENS’s activities are dependent on its architecture, which consists of two crucial components with separate purposes. The registry and resolvers are two crucial components of the ENS architecture. Let’s go further into the ENS architecture to determine the advantages of the Ethereum Name Service and how it operates.

ENS Registry

The registry, which is essentially a single smart contract, is the ENS architecture’s initial highlight. ENS registry facilitates the maintenance of a list of all domains and sub-domains, followed by the storage of three crucial pieces of data. The registry holds information about the domain’s owner and resolver. In addition, the registry retains information on the caching time-to-live for all domain entries. The domain owner in Ethereum Name Service may be a smart contract or a person with external accounts.


ENS turns web 2.0 into web 3.0

The ENS registry includes a registrar that serves as a smart contract for domain ownership. Subdomains of a given domain under the registrar’s authority are issued to users who comply with specified contract requirements. Among the rights of domain owners in the ENS, the Ethereum registry is the following:

  • Transferring subdomain ownership
  • TTL and resolver allocation for the domain
  • Changing domain ownership to a different location
  • The fundamental role of the ENS registry is to map names to their respective resolvers.


The resolvers are an integral component of the ENS design, bearing the bulk of responsibility for the network’s operations. Resolvers provide a clear response to the question “Is Ethereum Name Service secure?”. Resolvers are essentially intelligent contracts that assist the execution of certain standards. Some of the generic resolver implementations satisfy simple criteria, such as giving stable addresses for certain names.

The resolver must include mechanisms for delivering diverse records, including Bitcoin addresses and IPFS content hashes. Resolvers use the EIP standardization process at any moment to define new record types. Interestingly, the EIP standardization procedure eliminates the need for modifying the ENS registry or existing resolvers.

How Does Ethereum Name Service Work?

An ENS domain name employs ERC-721 Non-Fungible Tokens (NFTs) to represent a unique address. Transferring or selling the NFT is an option for exchanging domain names. Each token comes with its own set of private keys that may be used to access the owner’s wallet. A smart contract known as a registrar owns a top-level domain like .eth and is in charge of managing the development of subdomains under it. BinanceAcademy.eth could only be created by registering it with the .eth registrant.


How does Ethereum Name Service work?

You may find out whether a domain name for Ethereum is available and then rent it for a year. In the beginning, the most popular names were auctioned off. It was then up to the highest bidder to attach addresses, establish subdomains, and loan or sell their domain name. For instance, if you own, you may also build for free.

Getting Your Own ENS Domain Simple Guide

Using an Ethereum wallet like as MetaMask, you may search for available domain names at Once you have located your domain, the system will guide you through the registration process, which requires you to confirm two wallet transactions. 

You must also pick the number of years for which you want to register a domain, with yearly rent costing $5.00 (paid in ETH). Now, as the owner of this domain, you may configure the various locations or information to which you wish this name to connect, as well as any subdomains.


Setting up your own ENS domain

Why Is Ethereum Name Service Important?

Because the ENS was created for Ethereum smart contracts – and is unique to the Ethereum environment—it doesn’t suffer from the security vulnerabilities experienced by a DNS system. DNS records of domains and names are kept on a centralized server. That implies they are prone to hacking.

For instance, in October 2020, Google’s threat analysis department tracked a record-breaking 180,000 assaults on DNSs as well as on other network targets that were launched by Chinese internet service providers.

Conversely, ENS records cannot be erased and are safeguarded by the Ethereum blockchain.


Why is Ethereum Name Service important?

Additionally, with the ENS, names and addresses become more apparent and simpler to engage with. Anyone may create or register a “.eth” domain by engaging in an auction procedure. The highest offer will obtain the domain name, enabling the victor to build subdomains as well as lease the domains.

That allows users on the Ethereum blockchain a unique chance to set up business on the Ethereum network and become a distinct point of contact among a sea of addresses.
