I just started accepting bitcoin for potentially anonymous legal consultations. Does anyone out there have any advice for how to accomplish anonymous yet legally confidential attorney relations? I firmly believe in attorney-client privilege but know that a court order can force disclosure -- making the reality of confidentiality a question of court order.
I'm not qualified to answer about the legal rules surrounding confidentiality. (Though, I imagine you have a better handle on California/United States confidentiality than I do anyway.) However, there are a few technical details you should be aware of.
First, transactions in Bitcoin are essentially public. The transaction amounts and the time of the transaction are both public information. That means that if you're forced to disclose the amount and day of the transaction, someone could figure out the transaction that you were paid by.
Second, transactions are linkable. That means that if someone figures out which transaction you were paid by, they could follow the money that you were paid with, and they might be able to identify your client.
