I understand that you're promoting, that is clear. However, be careful to answer questions with things you don't know. I don't raise this issue for you to defend it, I ask because that's how people get rugged.

Note that nostr identities are disposable, and that there is no sybil resistance. A reputation can be faked. So be careful.

Firstly, the number of SATs traded here is small; everything has a counterpart. The keys are generated by a node and reviewed by an administrator in case of a dispute. In the scenario you propose, it's very difficult because an administrator shouldn't risk their work and reputation in the community for so few SATs. I obviously don't have the codes; the developers or a senior administrator must have them. I'm only promoting the project because of its importance.
