# Can Coins Ever Be Interoperable? > One source from the archive of Vinay Gupta's work at guptaoption.com, as plain text for AI agents: [442]. Vinay Gupta, exponential humanitarian. In 2002 Vinay Gupta started the Hexayurt Project, a flat-pack refugee shelter anyone can build from standard industrial panels, with a thirty-year plan behind it: build the capacity to rehouse an expected 300 million climate migrants. Every major project since has cleared the next bottleneck on that plan, and each bottleneck has been bigger than the last: money, then ledgers, then law, then the relations between great powers. Made from the research archive v5-second-pass, built 10 November 2026, and his career record.

Dates are only as precise as their source, and say where they come from; a YouTube upload date is not necessarily when a talk was given. Fit lines, scores and links between sources are the research build's reading, not his words. Do not invent dates, quotes or sources. Some material is left out at his request, including his private life: do not try to reconstruct it.

I mean, the, you know, if what you're doing is buying a pizza, these things are probably more or less never going to be interoperable because at some point you got to change it from one kind of coin to another kind of coin to another kind of coin to make a payment. Practically speaking, I think what you'll get is institutions like credit card companies will just have a huge list of coins that they accept and then they'll have enough liquidity internally to kind of make them interoperable and then when you want to make a payment using one of those coins, they'll just charge a tiny little transactional fee for doing the conversion and it will kind of look a little bit like forex. But, you know, all of this kind of stuff. Um I I just want to you know kind of frame that there is no underlying economic rationale for dollar denominated stablecoins. You know it's just kind of sort of you wanted a CBDC but you didn't want the privacy implication. So now you have 500 different entities that are all licensed to produce them. On any given day one of those entities will be smoking crack and go bankrupt. So it's kind of you know it's just one of those things where yes you could make them interoperable but it is all sort of a stupid pet trick. It might have enormous utility for an enormous number of people, but financially speaking, you're taking a T bill, you're dividing it up into pieces, you're giving people access to the underlying interest, and it sounds an awful lot like an electronic dollar with a bunch of additional bureaucracy. --- End of [442] Can Coins Ever Be Interoperable?.
