A decentralized domain name system (DNS) is an alternative to the traditional, centralized DNS system that is currently in use on the internet. To use a decentralized DNS system, a user must first register a domain name by creating a transaction on the blockchain. The transaction includes the domain name and the IP address of the website that the domain name should resolve to. The transaction is then recorded on the blockchain, and the domain name is added to the decentralized DNS system.
Unstoppable Domains is on a mission to enable every person on the planet to own their digital identity. The company is accomplishing this goal by creating web3 domains that empower users to take control of their data.
The Unstoppable Domain (UD) has similar goals to DNS, but with different architecture due to the capabilities and constraints of a Polygon blockchain. UD are Non-Fungible Tokens (NFTs) and are characterized by their decentralized nature. Unlike conventional domain names such as .com, UD are kept in the wallets of their owners, similar to how cryptocurrencies are stored. This unique feature ensures that no external party can modify or eliminate them.
At Polygonscan, we support UD names. They can be resolved to your Polygon address, and the domain name will be displayed as a name tag in the address page as shown below.
For further information on how we display UD on our website, please refer to this article.
