Last week I spoke at the National Cyber Investigative Joint Task Force's Digital Currency Symposium in Orlando. The NCIJTF is a multi-agency task force whose members include the FBI, NSA, CIA, Secret Service, and other law enforcement and technology-focused groups in the US government. The Symposium included talks from blockchain forensic firms Eliptic and Chainalysis, panels with compliance directors at leading exchanges as well as banks, and a talk from co-founding member of the Ethereum Foundation, Taylor Gerring. My presentation offered a review of open consensus mechanisms, specifically, and an explanation of why open networks are critical for certain applications: electronic cash, identity, and the Internet of Things. The response was overwhelmingly positive; it's good to know that law enforcement understands the tremendous benefits these technologies promise given they typically spend their days mostly focused on the risks.
