Re: How do bank payments actually work?

Please bear me with me for my ignorance...

..but I would like to understand this a tad better:


   - I have seen similar ideas in complementary currency spaces, the idea
   being that value can be exchanged over different currency circles
   - It never took off because the underpinning values systems differ too
   heavily - there's no way to , bridge a local money X with another Y,
   there's too much difference in money design and value systems

Now, my questions for these interledger exercices, are you guys talking
about interledger,

   - but based on the SAME currency as value exchange? Or different ones?
   - based on fiat currency, and/or bitcoin?
   - no currency at all, "just" sync records?
   - generic interledger which would work no matter what resource the
   ledger is actually focused on?

Maybe my questions are completely off, if I in fact would have understood
things completely wrong.

Would welcome a brief clarification, thanks.
