If you have a question about this talk, please contact Adrian Kent.

I describe a new conception of secure money tokens relevant for networks on which there are trusted relativistic (or other) signalling constraints. I show how these tokens have many of the security and flexibility advantages of quantum money, and can also implement some tasks that quantum money cannot, without requiring long term quantum state storage. I also discuss some potential drawbacks and difficulties.
