Ethereum name services (ENS) allows you to register your hexadecimal bitcoin or crypto address into a human readable name. It is similar to the DNS (Domain Name Services) that we're currently using for websites, which translates a more readily memorizable domain names into numerical IP addresses needed to locate computers and servers in the network.
district0x developer team is currently working on a online market place, Name Bazaar, in which users can purchase or exchanges ethereum based names with other users.
The platform is currently under development but assuming things go as planned it will be launched by the end of the month.
