A Guide to Unstoppable Domains - Part1

This is Part 1 of an article series about Unstoppable Domains. Here’s a link to Part 2

Blockchain domains have become a hot commodity this year. Indeed, great domain names can cost as much as blue chip NFTs like Bored Apes or CryptoPunks. Nowadays, many people recognize the need for a good blockchain domain name. With that, domain name providers like Unstoppable Domains and Ethereum Naming Service (ENS) have become popular and essential to a blockchain ecosystem. 

In the first part of this article series, we explore the world of Unstoppable Domains. We look into what it is and what it does. Moreover, we explore how its backend works and whether it’ll launch a token.

What Is an Unstoppable Domain?

Before we delve in, let’s start off with the basics. A blockchain domain is a domain name mapped to your wallet address. With this domain name, your address is much more readable. Imagine sending ETH to 0xA1F92257248eb0B3Db4bE6b36c46D1B19C11da6f. I’m sure you’d be stressed out. Now if you’re sending ETH to Tommy.eth instead, wouldn’t that be much better? In addition, your domain can also interact with decentralized applications (dApps) and exchanges. How cool is that?

Moving on, an Unstoppable Domain is a domain as well. Moreover, they are domains that are secured through this company called Unstoppable Domains. Said company provides blockchain domain names to users like you and me.

Now, if you compare it to ENS, which provides .eth domain names, there are slight differences. This is despite both of them being domain name providers.

First, ENS provides .eth domain names. But, Unstoppable Domains specializes in these domain names instead:

  • .crypto
  • .nft
  • .x
  • .wallet
  • .zil
  • .bitcoin
  • .blockchain

And much more!

Second, notice that Unstoppable Domains provides .zil domains. This is because they exist on both Ethereum and Zilliqa blockchains! Now, we’ve even got some news that they may also be heading to Polygon. How do we know? Well, we could say that the little tweety bird below told us. On the contrary, though, ENS names only exists on the Ethereum blockchain at this moment.

So, this means an Unstoppable Domain could exist on Ethereum, Zilliqa, and Polygon. Also, they could exist in many forms, such as .zil, .x, .wallet and so forth.

What Does Unstoppable Domains Do?

That’s easy to answer! You already know that they issue out domains to their users. Well, you’re right. But that’s not all!

These domains help onboard retail investors into crypto. With domains, people can read addresses better. They’re also able to interact with dApps and exchanges better too. With an improved user experience, more investors will hop on to the crypto bandwagon.

By selling domains, Unstoppable Domains is, in essence, selling NFTs. Each domain exists as an NFT on their respective chain. Furthermore, if you bought an Unstoppable Domain, you only need to pay a one-time fee. You do not need to pay recurring fees to the company. That’s a lot of savings compared to buying an .eth domain from ENS.

But, how are they able to offer this? The answer lies in their backend. Let’s take a peek at their architecture.

How Does Unstoppable Domains Work?

Simply put, the service is built on Crypto Name Service (CNS). This is a set of smart contracts that govern domain name issuance and management. Notice that this is different from ENS’ Domain Name Service (DNS). Indeed, a CNS domain is designed such that an owner of said domain will own it forever without recurring fees.

Registry and Resolver

The two main components of CNS are its Registry and Resolver.

  1. Registry. A Registry is a smart contract. It acts like a directory. It holds all domain name data. In addition, it holds the owner address and Resolver address for each domain.
  2. Resolver. A Resolver is also a smart contract. In CNS, there exists many Resolvers. These contain a map of historical data linked to each exact domain.

So, in the backend, it all comes together. When you’re using your domain, the Registry is called to learn your domain address. Then, the Resolver is called to read your domain’s associated records.

A unique feature about CNS is that it has a smart contract called ProxyReader. This feature is able to combine the above two steps into a single smart contract call. Not only does this improve the speed of CNS, gas fees are reduced for the users too.

Will Unstoppable Domains Have a Token?

Unfortunately, we do not have news on their future plans for a token. That is to say if they even plan to release their own. Now if there is any news on this, we’re sure the announcement would be through their Twitter. Feel free to drop them a follow!


So, this marks the end of Part 1 of this article series. Here, we answered four questions about Unstoppable Domains. We’ll get more of your queries answered in Part 2 of the series, which you can read here.
