After many discussions and a lot of trial and error, we finally have a simple and efficient way to allow an admin to intervene in dispute resolution. I just uploaded a repository explaining how Mostro clients handle chat between users. We use a Diffie-Hellman shared key between the two parties as a master key, which either party can voluntarily share with the solver in case of a dispute. This way, the solver can verify who is lying. For the curious, the repository technically explains how it works and includes sample code. I’m currently implementing it in mostro-cli, and I hope to add it to Mostro’s official documentation today. @Mostro client builders can now implement user chat without worrying about changes—this will be the scheme we’ll stick to.
