Nick Johnson and Alex Van Sande, two ethereum developers, have successfully launched today the Ethereum Name Service (ENS), which acts like a domain name service for ethereum addresses, smart contracts, dapps and other services.
Instead of a long, random, very difficult to remember string of numbers and letters which make up a public ethereum address – somewhat similar but far longer than an IP – ethereans can now just bid for an ethereum name, allowing you for example to directly send funds to trustnodes.eth, rather than copy pasting a random combination of numbers and letters.
