I think it might work better if trust was a number from 0 to 1 instead of a boolean, which would allow for different exchange rates, which would be useful if e.g. different sub economies formed separately with a different price for certain goods, so that the prices of the things with the different units aren't forced to change when the the two parts of the economy join into one. I don't think I explained that well. To make a concrete example, suppose there are two collections of people/accounts, where each person/acc in a group trusts each other one in the same group (so that they can exchange their types of currencies automatically at a 1:1 rate). Suppose that in each of the two groups, there is a person who sells chicken drumsticks. If they are selling them at significantly different prices, then it seems there could be a problem if the two groups try to connect, because then one person could buy the currency in which the chicken costs less, buy the chicken, sell the chicken where it costs more, getting back more money, repeatedly, as an arbitrage thing. If it was just chicken this might not be a problem, as the two main chicken sellers would just settle on a common price for chicken, but if there were many types of goods, such that there was initially a source of arbitrage for every type of good produced in both communities, that seems like it would lead to problems. A solution, I think, would be for when the two communities connect, by extending "trust", instead of establishing automatic 1:1 exchange, instead it could be made so that when a person trusts another person, they make it so that the other person can purchase up to a certain amount of their type of currency, at a cost of some amount that they choose of the trusted person's currency (an exchange rate). In this case the exchange rates would be potentially asymetric, and there would be questions of "what is the cheapest exchange rate path to get personcurrency A from personcurrency B?" and theres also possibilities of arbitrage in the trust trading of currency stuff, but the limit per time would probably reduce that I guess, and I think it would probably self correct (be EMH). IDK if that would be worse or better than with many types of goods and the exchange rate between currencies being forced to be 1:1, but I think it would probably be not as bad? I am not sure. I'm fairly ignorant in this, but I thought the circles idea was interesting, and thought that a modification might be useful as described above. maybe.
