TechTalk 11/17/15 – Blockchain: The Part of the Iceberg Beneath Bitcoin

In this TechTalk, Dr. John Callahan discussed “Blockchain: The Part of the Iceberg Beneath Bitcoin.” He examined the general structure of blockchain technologies that support bitcoin, their foundations, exploits, and new applications including alt coins, smart contracts, and distributed applications (DAPs). He also presented the broad technical possibilities of blockchain, and surveyed the social and legal impacts of a pseudo-anonymous transaction ledger for currencies, contracts, file systems, databases, and other proposed applications. Callahan is currently the chief scientist of the Applied Information Sciences Branch of the Asymmetric Operations Sector at the Johns Hopkins Applied Physics Laboratory.
