Not yet. Ethnamed protocol is implemented under the Ethereum blockchain.
It helped us to understand the problems of blockchain and think about a solution.
In case of Ethnamed you will be able to assign an email address to your ETH, BTC, ... addresses and send money in a human-readable way.
This project is proof-of-ability of the team to implement what we can would like to implement.
You can review our code, the way of thinking, etc.
