Let's talk about this thing: How to create Ideal Money?

Why don't we call our hypothetical perfect currency, let's say, RESERVEUM. There is double meaning in this name:

1) an ideal currency of the future that must be totally asset-backed.

2) an ideal currency that is to become the global reserve in the future

Is it even possible to create such ideal currency?

What features should it have?
