How simple can an ecash mint be? For the simplest case there should be no accounts. All the mint does is exchange coins for other coins. There are no customer lists, no records of transactions (except as needed for double-spending detection). 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. Implemented in tamper-resistant hardware (a dedicated box or process could substitute, but hardware is easier, and I have plenty): stage 1: * Some protocol for external

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. Users should
