Thank you! Very helpful resources.

@Maeher Yeah I agree, it's not very clear to me at this time too. I was just entertaining this notion to see if something can come out of it. Wanted to check if something similar already exists in the literature by asking it in here.

@Maeher Well ideally, we should prevent double-spending attacks and creation of money out of thin air. B should not able to collect more than the sum of individual payments. I don't know whether this is possible at this point.
