yeah, the idea is to have many of them and for them to have an exchange connecting them so payments from one mint can be redeemed by another with minimal human intervention

the ontology of their mechanism of operation does also mean that they can only really scale up to a certain size of userbase before the complexity of the relationships exceeds practicality

and lightning is a perfect way to enable the inter-mint exchanging

so yeah, i agree, ecash mints will perform an important task, and will be pretty cool for a while until it gets really popular and you get "wildcat mints" and politicians, with no visible prompting *sarcasm* offer to "certify" mints

hopefully by that point we have obsoleted banking institutions and their shadowy influence on government
