Traditional domain names have been in use for decades and are widely recognized. However, they come with certain limitations due to their centralized nature. Organizations that registered these domains are usually the ones who own them, which means that individuals have no control over them.

Meanwhile, the Ethereum Name Service (ENS) is a decentralized alternative to traditional domain names that offers additional functionalities. It represents a significant change in the way we think about and use domain names on the internet. ENS provides users with more control over their domain names, making it a powerful tool for individuals and businesses alike.

Given these options, SelfKey aims to provide subdomains with self-sovereign identity in mind. With SelfKey's ENS subdomains, individuals may enjoy all the benefits of owning a regular ENS domain on the Ethereum Mainnet without the recurring additional costs. 

By offering greater control and flexibility, SelfKey’s ENS subdomains may enable users to better manage their digital identities and online presence. And this may make it a valuable tool for anyone looking to build a presence on the internet.

In this article, we will elaborate on the benefits of ENS (Ethereum Name Service) over DNS (Domain Name System), as well as the advantages of SelfKey ENS subdomains

The Basics of DNS

DNS (Domain Name System) is a traditional system that facilitates the translation of human-readable domain names, such as, into IP addresses. Every device connected to the internet has an IP address, which represents a unique numerical identifier.

This process is necessary because while people can easily remember and recognize domain names, computers and other devices require IP addresses to communicate with each other. 

DNS is an essential part of the internet infrastructure and is utilized in a variety of applications, including website hosting, email communication, online gaming, and more. 

Without DNS, users would have to memorize the IP addresses of every website they wish to visit, which would be highly impractical and inconvenient.

ENS Unpacked: A Quick Overview

A brief description

ENS (Ethereum Name Service) is a decentralized naming system built on the Ethereum blockchain. It allows users to register human-readable domain names, similar to how traditional DNS works, but with added features and benefits.

With ENS, users can register domain names in the form of "name.eth" instead of the traditional "" format. 

Noting that these domain names are unique, one can use them to identify various Ethereum-based resources, such as wallets, contracts, and decentralized applications.

ENS and individuals

One of the main advantages of ENS is that it is decentralized. This means that no single entity or authority owns or controls it.

Even more, resistance to censorship is boosted and individuals are allowed to have more control over their online identities and assets by being decentralized.

Another positive aspect of ENS is that it is interoperable, meaning it can be used across different applications and services on the Ethereum blockchain. This could help create a more seamless and integrated user experience.

The Benefits of ENS compared to DNS

Both ENS and DNS are used for assigning user-friendly names to machine-readable addresses on the internet. However, there are several key differences between them, namely:

  • Centralization
  • Ownership
  • Security
  • Functionality

Below, we will discuss these important aspects more in depth.


The traditional DNS system is centralized, with domain names being registered and managed by a single authority, ICANN. On the other hand, ENS is a decentralized system that operates on the Ethereum blockchain.

As a decentralized system, ENS is not controlled by a single entity, which gives individuals the freedom to manage their very own domain. This liberty allows users to express themselves and utilize their domains to their personal needs. 

ENS users may stand out more if they are not attached to a centralized giant. And this, in turn, may give them the opportunity to attract and engage with other individuals. All in all, having the freedom to manage their own domain in the online world comes with a large number of chances for users to show off their services or skills.


Ownership is another key difference between ENS and traditional DNS. With traditional DNS, the organization that register domain names typically own them. ENS allows individuals to own their domain names directly, without intermediaries. 

This means that individuals can have complete control over their domain names, which can be particularly useful for businesses and individuals who value their online presence. 

Owning an ENS domain that matches their business or brand name may help individuals build brand recognition and increase trust among customers.


Security is another major advantage of ENS over traditional DNS. Most centralized systems have weak security, which often leads to data breaches. Those whose data was compromised might suffer dire consequences as a result of this. Being a centralized system, DNS might be quite risky in this sense.

Meanwhile, ENS's decentralized architecture makes it highly effective in preventing security threats. It operates on the Ethereum blockchain and uses the same cryptographic standards as Ethereum, providing an additional layer of protection. 

This feature makes it very difficult for bad players to compromise the system or steal user data. It may also make the systems more resilient to hacking or domain hijacking. As a result, ENS offers a much higher level of security.


ENS provides unique functionality compared to traditional DNS. 

One such feature is the ability to link multiple addresses, including cryptocurrency wallets, to a single domain name. This capability makes identity management more simple for users and it enables seamless interaction with decentralized applications. 

Another positive aspect of ENS is that it allows users to build their online identity and streamline their transactions. On the opposite side, traditional DNS only offers basic domain name resolution. This added functionality is another reason why ENS is becoming a more and more popular choice for those seeking a more flexible and user-friendly domain name resolution system. 

All in all, ENS and traditional DNS serve the same purpose, but they differ significantly in terms of centralization, ownership, security, and functionality. And all of these aspects are highly important to take into account as society becomes more digitized.

With these possibilities in mind, SelfKey is aiming to create a subdomain that offers the same benefits as the current ENS, along with additional features that may enhance accessibility for individuals.

SelfKey ENS subdomain: Definition and Benefits

When developing new technologies, SelfKey prioritizes the concept of Self Sovereign Identity (SSID), and the SelfKey ENS subdomain is a prime example of this approach. 

Through the creation of a subdomain, SelfKey is aiming to make it easier for individuals to manage their online identities and interact with decentralized applications. This technology is centered on empowering users and it may provide them with greater control over their personal information. 

All in all, SelfKey’s goal is to bring a positive change to the way people operate in the digital world. To make it more secure and accessible for everyone.

What is SelfKey ENS subdomain

SelfKey ENS subdomain is an innovative subdomain that aims to provide a more accessible and user-friendly domain name resolution system. Given this, users might not have to pay recurring fees for their subdomain. 

SelfKey ENS subdomain is likely to be a subdomain of key.eth. This means that users may register their preferred subdomain by adding their name or any other word of their choosing, such as yourname.key.eth. This naming convention is similar to email addresses. And, by providing an easier way to identify and interact with Ethereum addresses, it may bring self-sovereign identity closer to mass adoption. 

Just as DNS made the internet more accessible to the masses by providing a simpler way to access websites than using IP addresses, key.eth may do the same for Ethereum addresses. It replaces long, complex addresses with a human-readable format that is easy to remember and share. 

This may improve the ease of use of the blockchain and help resolve one of the challenges to widespread adoption. Because of this, key.eth may be a step towards a more user-friendly and accessible blockchain ecosystem.

What are the benefits of SelfKey ENS

SelfKey ENS subdomain is designed to make it easier for individuals to manage their online identities and interact with decentralized applications. By putting user accesibility first, SelfKey is aiming to create a more inclusive domain name resolution system that builds on the strengths of ENS while adding to its advantages. 

This innovative approach might make SelfKey ENS subdomain a compelling choice for anyone who values privacy and security, and wants a more user-friendly way to manage their digital identity.

SelfKey ENS subdomain provides several benefits to its users:

  • One of the primary advantages of SelfKey ENS subdomain is that every verified SelfKey iD holder may receive a free key.eth subdomain on the Ethereum Mainnet that is longer than seven characters. This free subdomain may allow users to experiment with SelfKey ENS subdomain and explore its features without having to make extra financial commitment.
  • Once users have their free subdomain, they may buy more subdomains using any of the supported tokens. Users may utilize these subdomains for various purposes, such as getting payments or creating aliases for use in games. Users may buy as many subdomains as they like and use them to streamline their online activities.
  • Another significant benefit of SelfKey ENS subdomain is that users may sell their subdomains.  Any marketplace that supports ENS trading, such as OpenSea, is a good place to start. This feature may offer users the freedom to experiment with different subdomains. And, if they decide to change their online identity or activities, they may sell them.

Overall, SelfKey ENS subdomain may provide great benefits to its users. It may enable individuals to not only manage and own their domains, but also boost their visibility online. These features might make SelfKey ENS an ideal choice for anyone looking to enhance their online identity and activities.


It's important to note that people have become increasingly aware of the importance of privacy and ownership of personal data. However, the traditional centralized systems we rely on for managing our digital assets and domains may compromise these rights. This is where the Ethereum Name Service (ENS) comes in as part of an ideal decentralized future.

ENS allows individuals to own and manage their own domain names on the Ethereum blockchain, which is decentralized and secure. This means that no central authority has control over the domain name. A feature which gives individuals complete ownership and control over their online identity.

SelfKey ENS may be one such solution that offers individuals the opportunity to manage and own their own domain names without the limitations of traditional domain names. This may not only give users more control over their online presence but also provide greater privacy and security.

As technology continues to advance, it is important for individuals to stay informed about potential decentralized solutions that can benefit their privacy, security, and self-sovereign rights.
