Jonathan Levin, cofounder and chief operating officer for blockchain analytics company Chainalysis, describes how the company was born out of questions he had while a grad student, how they began mapping the Bitcoin blockchain to certain entities, and how their customers, which include government agencies such as the FBI, DEA, IRS, Europol and others, use Chainalysis to help solve Bitcoin crimes. He also reveals what level of detail the software tracks, how privacy coins could affect their work, and what new developments in the technology could decrease current crimes, such as physical extortion of crypto holders. Plus, he answers the question of whether or not Chainalysis's work destroys the fungibility of Bitcoin.
