ENS (Ethereum Name Service) domains typically include a primary name and a top-level domain, like 'vitalik.eth'. In this structure, 'eth' is the top-level domain, and 'vitalik' is the primary name. ENS subdomains add a third-level domain, creating more detailed domain names under the primary ENS domain.
Owners of an ENS domain have the ability to create subdomains. These subdomains can be assigned to anyone, such as employees or community members, with the only cost being the gas fees for registration. Additionally, ENS domain owners can use platforms like ens.vision to offer their subdomains for minting, potentially for a fee.
ENS subdomains offer several advantages:
Affordability: High-demand ENS domains like 'god.eth' can be expensive, but subdomains provide a cost-effective alternative. For instance, 'travis.dev.eth' could be minted at a lower cost.
Identity and Branding: Similar to full ENS domains, subdomains can be used for financial transactions and to build a Web3 identity. They are particularly useful for projects and brands looking to establish a presence on the blockchain. For example, a project like 'ethscriptions.eth' issuing subdomains can help supporters be easily recognized and foster a sense of community, much like profile pictures (PFPs) but with more practical utility.
In summary, ENS subdomains extend the functionality of Ethereum Name Service, offering a versatile, cost-effective solution for digital identity and branding in the Web3 space.
