This week, Brookings hosted a discussion on Bitcoin and the technology that undergirds the currency, specifically focusing on the promise of the distributed-ledger. The panel featured David Wessel, Michael Barr, Brad Peterson, Barry Silbert, and Margaret Liu, on how the blockchain could revolutionize payment flows and reduce the cost of financial transactions, all while securing information and enhancing privacy. They also tackle some of the most pressing policy questions facing the technology---from consumer protection to terrorists' finances---and how those tensions can be addressed. It's a relatively positive take on Bitcoin and its future potential and an argument for why you should buy back your Bitcoin if you sold it after last week's show featuring Lawfare's Bitcoin skeptic, Nick Weaver.  See acast.com/privacy for privacy and opt-out information.
