I wondered it might be something along those lines. As a side note, it would be an interesting challenge to figure out how many nodes you’d have to subpoena in order to determine with any degree of certainty the origin of a coin.
My revisions to OutputDebugStringF will, by default, NOT log anything to do with individual transactions. Basically, only infrequent status messages such as the hash rate, warnings, errors and critical errors will be logged by default.
Actually, before I go too far down the road with it, I think I’ll open a discussion on the Bitcoin forums to get feedback on my ideas. Maybe someone there might have some additional thoughts on privacy issues.
