Court protects the privacy of bitcoin address and transaction information

Defendant asked the court to redact his bitcoin address and transaction information from exhibits used at trial, which ordinarily would become part of the public record. He argued that for each transaction recorded on the blockchain, one could reverse engineer the entire transaction if he or she knows the individual associated with one of a number of pieces of information, including transaction ID and public bitcoin address. “[O]nce a particular individual is associated [with] any of this information, it is essentially akin to providing that individual’s financial account number.”

The court allowed the redaction of the bitcoin address and bitcoin transactions. It found that defendant had demonstrated good cause to support the redactions. The court balanced the public’s right of access to court information against defendant’s interest in keeping the information confidential. It agreed with defendant’s assertion that the bitcoin information he sought to redact is akin to a financial account number or personally identifiable information.
