The Ethereum Name Service (ENS) is a decentralized naming system built on the Ethereum blockchain. It allows users to replace long and complex cryptocurrency wallet addresses with simple, human-readable names like yourname.eth. This transformation makes interacting with blockchain technology more user-friendly and accessible.
Beyond simplifying transactions, ENS also functions as a Web3 identity passport. It enables the creation of a consistent and recognizable digital identity that works across various decentralized applications and platforms. As a result, your ENS name supports both transactional ease and personal branding within the wider Web3 ecosystem.
History of ENS
ENS was introduced in 2017 by developers affiliated with the Ethereum Foundation. The goal was to build a decentralized domain name system inspired by the traditional Domain Name System (DNS) but operating entirely on the blockchain. Since its inception, ENS has grown significantly in adoption and functionality, attracting a global community of users and developers.
Key Features of ENS
ENS stands out due to its decentralized architecture and reliance on Ethereum smart contracts. This design ensures enhanced security and makes the system resistant to censorship. Unlike traditional naming systems, ENS allows a single name to be linked not only to wallet addresses but also to other types of data, including content hashes, metadata, and even profile information.
This versatility means your ENS name can serve as a unified identifier for various digital assets—such as cryptocurrencies, NFTs, and decentralized websites—streamlining your entire Web3 experience.
How ENS Differs From DNS
Although both ENS and DNS map readable names to resources, they differ fundamentally in structure and philosophy.
- Decentralization: DNS relies on centralized authorities to manage and control domains, which can lead to censorship or seizure. ENS, by contrast, gives users full ownership and control over their domains via blockchain technology.
- Security: ENS uses cryptographic proof mechanisms native to Ethereum, making it highly secure against unauthorized changes or hijacking. Any update requires permission from the domain owner’s private key.
- Censorship Resistance: Centralized DNS systems are vulnerable to governmental or institutional interference. ENS, operating on a decentralized blockchain, has no single point of control, making it extremely difficult to block or take down.
- Blockchain Integration: ENS is natively integrated with Ethereum and can interact with smart contracts, enabling advanced functionality like automated payments or identity verification—a feature DNS does not support.
Benefits of Using ENS
Adopting an ENS domain offers numerous advantages for both new and experienced cryptocurrency users.
Improved Convenience
ENS simplifies blockchain transactions by turning complicated addresses into easy-to-remember names. This reduces errors when sending or receiving funds and enhances usability. Additionally, ENS names can be used as a portable digital identity across platforms, social profiles, and even in real-world contexts like business cards.
Enhanced Security
By using a readable .eth address, users minimize the risk of sending assets to incorrect addresses. The underlying blockchain technology also provides strong protection against fraud and hacking.
Greater Flexibility
An ENS name can be linked to multiple addresses across different blockchains, content hosted on IPFS, or other off-chain resources. This makes it a versatile tool for managing your digital presence.
Broad Compatibility
ENS is widely supported across major cryptocurrency wallets, dApps, and exchanges. This ensures your ENS name works seamlessly wherever you need it.
Full Ownership and Control
Users have complete sovereignty over their ENS domains. Once registered, a domain cannot be altered or confiscated by any third party, ensuring long-term stability and self-custody.
How to Get Started with ENS
To register an ENS domain, you will need a small amount of ETH to cover the registration fee and gas costs. You can use any Ethereum-compatible wallet to manage your domain and configure its settings.

A typical registration process involves:
- Connecting your wallet to the ENS app.
- Searching for an available domain name.
- Completing the registration transaction.
- Configuring resource records and settings as needed.
Frequently Asked Questions
What is an ENS domain?
An ENS domain is a human-readable name that points to an Ethereum address or other Web3 resources. It serves as a simplified identifier for sending crypto and representing your identity online.
How much does it cost to register an ENS name?
Costs vary based on name length and demand. Registration requires paying a yearly fee using ETH, which also covers network transaction costs.
Can I use my ENS domain with multiple blockchains?
Yes. ENS supports multi-chain resolution, allowing one domain to point to addresses on various networks such as Bitcoin, Litecoin, or Polygon.
Is my ENS domain permanently mine?
ENS domains are renewable on an annual basis. As long as you renew the registration, you maintain ownership and control.
Which wallets support ENS?
Most modern Web3 wallets, including MetaMask, Trust Wallet, and others, offer native support for ENS domains.
Can I transfer or sell my ENS name?
Yes, ENS names are tradable NFTs. You can transfer, sell, or gift them through supported marketplaces or peer-to-peer transactions.
