I just registered an ENS domain: klaudioz.eth
It replaces the need to use a 42 hexadecimal characters ETH wallet address with something easier to remember, like the ENS domain.
ENS lives on smart contracts on the Ethereum blockchain and is censorship-resistant, not like the typical DNS.
Also, it can be used not only for websites. With this new technology, Dapps and more Dweb resources/services will be benefited.
I set this after starting watching: Ethereum and Solidity: The Complete Developer's Guide. The best way to learn for me is by doing.
