I just committed an example of "simple money" implemented in #Spritely Goblins https://gitlab.com/spritely/goblins/-/blob/dev/goblins/actor-lib/simple-mint.rkt
25 lines of code and fully transactional (any error that occurs won't corrupt the bank's state, will preserve the amount of money in it). No blockchain required.
Based on the recipe from: http://erights.org/elib/capability/ode/index.html
And yes, you can access your accounts across servers in this system using CapTP.
