John McAfee, the eccentric antivirus pioneer known for his brushes with the law, said he has spoken with bitcoin creator Satoshi Nakamoto and plans to reveal the person's identity shortly.

The background of Nakamoto — a pseudonym that is thought to refer to a person or group of people — has been fiercely debated for years, with a long list of discredited theories fueling suspicion bitcoin's pioneer is probably dead. In recent days, McAfee has been threatening on Twitter to out Nakamoto, saying that he's a man living in the U.S. McAfee has said that he will take the step unless Nakamoto comes forward voluntarily.

McAfee is now saying that he'll expose Nakamoto "within a week."
