How Bitcoin Led to the Demise of the Largest Child Porn Site - Ep.95

Jonathan Levin, the cofounder and chief strategy officer of Chainalysis, describes how the blockchain analytics firm helped the IRS identify the administrator of the largest child porn website in the world, which ultimately led to the arrest of the administrator, Jong Woo Son, and 337 site users across 38 countries. The work also led to the rescue of 23 minors from their abusers. He describes how the site used Bitcoin, how they used Bitcoin transactions to identify the users of the site, and how law enforcement worked with exchanges. We also discuss what impact privacy technologies could have on similar investigations going forward, as well as Levin's perspective on the overall utility of Bitcoin despite it being used for illicit activity.
