The main idea of this project is very attractive...imagine just using a simple domain instead of that complex wallet address with long stretch of letters and numbers. Here your domain is your wallet address so you can buy a domain name with your very name on it and whenever someone is asking for your wallet address just share the domain you registered in this site. Well, very useful indeed. Now, I wonder why the use of .zil then I read that it is because this is launched in the Zilliqa blockchain and a grantee of the Zilliqa Foundation to work with the extension. I am then wondering: Will it mean that my domain name is the same wallet address I can use for all cryptocurrencies and tokens...meaning the same for Bitcoin, Eth, and the rest of the gang?
I definitely think you're able to use crypto like BTC, ETH and LTC according to their website. I am not sure if the .zil will always be the same or if that will change over time as well.
