Thanks for the mention, and for all these details.
I can see how Koinos smart contracts will be easy to create and interact with. There has been talk here about extending the things that can be done with HBD, like staking longer for more rewards (something like bonds). Maybe that's a way to mash-up Hive and Koinos.
Maybe projects like SPK Network, DLUX, some Hive games, things Blocktrades has planned - can benefit from what Koinos offers. I guess we'll soon see!
Yes, such changes would be trivial on Koinos. In fact, there would be no need to even discuss them, any developer could just code up the behavior in a smart contract and deploy it to the chain.
