In the white paper of MultiChain, "A further benefit of supporting multiple blockchains is the ability for a server to create connections between the activity in different chains. For example, an institution may want the arrival of funds on one blockchain to trigger a corresponding transfer of funds on another."
In that case, MultiChain seems to have a lot of very attractive features. As I read the white paper, I have some question.
When I create multiple blockchains on one system, how can I share transactions among those blockchains, or link/trigger activities between different blockchains? Should I use a specific API? Or is there another method or function?
In case of 'permissions-based mining', if 'mining diversity' is zero, then do the nodes participating in the blockchain network mine new block through the proof-of-work hashing in bitcoin-style?
Thank you so much for your contribution.
