In the future of space, space money is still used. Most is digital,

What did nazi money look like?

Rigid rectangles made out of translucent green plastic. The relevant currency symbol is printed on the side, and some sort of circuitry is visible within, which may or may have to do with the things actually interfacing with anything electronic.

The catgirl has been a universally accepted monetary unit for several hundred years, due to difficulty of production, long lifetime, and the gene-reserve standard guaranteeing rarity and thus value.

Space money will likely be blockchain based. Most likely with some advanced form of a proof-of-stake stransaction securement as proof-of-work would go out the window as soon as quantum computers would be available .

Gold backed currencies would be a thing of the past given how incredibly fucking expensive it would be to ship gold from planet to planet. Other forms of backing would also run into the shipping problem as well.

Fiat digital currencies would require an astronomical (hehehe) amount of bureaucrats and armies to keep functioning between planets.

Physical currencu would just be very fancy passwords on notes for transaction addresses.

In the culture novels there was one race that was the banking specialists who based their currency on a set unit of digital storage cross referenced with a set unit of space on an orbital station. so its value changes with inflation only when technology allows for better digital storage. I think the currency itself is stored on encrypted data chips.

Uhh, gold has one of highest value densities of any material in the world. If it's that fucking expensive to ship things across space, you're not going to be shipping much of anything else.
