The Internal Revenue Service is using bitcoin transaction tracing tools developed by startup Chainalysis, according to a new report.
Documents obtained by Washington publication The Daily Beast show that the tax agency has been using the startup's software since 2015.
Additional data from the General Services Administration, which handles the US government's logistics, indicates that the IRS has an active contract with Chainalysis that is valid through the beginning of September. To date, the IRS has paid Chainalysis more than $88,000.
