@contrapunctus Coming up with a system like this is no easy task, as there are a lot of factors to consider. Privacy, security, fraud and legal requirements to name a few.

1. It should be as easy as possible to make a payment, ideally without requiring a third party payment processor.

2. It should be viable to pay and receive really small amounts without getting eaten up by transaction fees.

3. It should be flexible enough for creators but rigid enough to not be confusing for customers.
