"Bank of America was awarded a patent for a device that stores cryptographic keys and the document's details hint at applications for cryptocurrencies.

In a patent awarded Tuesday by the U.S. Patent and Trademark Office, the bank outlines a "hardened storage device" for storing private keys – such as those used for blockchain platforms – explaining that, at present, most keys are stored locally protected by nothing more than a password."

Would this make banks responsible for uncontrollable losses? This will be great for adoption and hints at a future where banks essentially regulate smooth digital transactions and keep them secure.
