Dogeparty: Could it be? That an altchain is being used? My god! That is not bitcoin!
If you think speed and cost of action is not a big issue, if not the major issue that even started the idea I belive that you are mistaken. Speed and Cost of action are the major advantages of dogeparty. The advantage of viacoin and clearinghouse is that the developers of the coin are 100% behind the clearinghouse project, not to mention being cheaper and faster. Are the bitcoin core devs 100% behind counterparty? Are the dogecoin devs 100% behind dogeparty? Viacoin a large OP RETURN, what about dogecoin and bitcoin? Counterparty can swich to another blockchain if the core devs go nuts and somehow block it from working on the bitcoin blockchain, that should be possible.
