what about buying and selling of domains, will there be a fee?
neverthless, you can have my 20 domains i have registered within sedo.com

As written whitepaper:
● Save thousands of fees on domain related transactions
So i guess there will be fees, but much lower than usual.
Also you will probably save fees because you can do everything at one place and don't have to pay all the different provider, but not sure about this.
Maybe we can get more details about this.
