Golden Finance reported that investigative journalist Dave Troy said that the Federal Bureau of Investigation (FBI) issued a "Glomar response" to its request for information about Bitcoin founder Satoshi Nakamoto under the Freedom of Information Act (FOIA), which is "neither confirming nor denying" whether relevant records exist. Troy said that the FBI's response implies that Satoshi Nakamoto is a "third party individual". He plans to appeal this and try to obtain information about Satoshi Nakamoto that the FBI may have. Since the release of the Bitcoin white paper in 2008, the true identity of Satoshi Nakamoto has been a mystery. Although some people speculate that early Bitcoin contributor Hal Finney may be Satoshi Nakamoto, there is no conclusive evidence so far. A similar FOIA request received the same response in 2018, showing that the FBI and CIA are cautious about the records of Bitcoin's founder.
