How simple can an ecash mint be?
For the simplest case there should be no accounts. All the mint does is

The very simplest mint is a pure ecoin changer.
Actually, I think to be practical you want something only
slightly more complex; 3x as much work, but 100x as useful.

could substitute, but hardware is easier, and I have plenty):

A message is simply a packet of data. Using a message-based protocol

I don't believe normal users should ever interact directly with the
mint; using the mint as a reissue server only in normal operation is a
key optimization -- especially when coupled with tamper-resistant mint
hardware. Easier to develop, easier to operate, easier to audit.
