This is way over my head... 🙂
Is this useful to prevent Mints from unchecked money-printing (I have a feeling this issue is still somewhat unresolved in ecash)?

Nope, that's a different area of research. I plan to build this as part of my ecash mining pool project after I get the core functionality working. https://gist.github.com/callebtc/ed5228d1d8cbaade0104db5d1cf63939
