Here are a few that seem to be doing some interesting things (in no particular order):
Crypti, Qora, IOCoin, SuperNET, NEM, Horizon, NXT, Burst
Can anyone speak about how other platforms like these can actually be integrated with Bitshares? I understand they can utilize the Bitshares blockchain instead of their own by issuing a UIA for their own currency. But most (if not all) of those listed above are more than just a coin. So what about the functionalities they are building? Would their devs need to become Bitshares devs and port their functionality over?
