https://www.coindesk.com/new-bank-of-america-patent-hints-at-plan-to-store-cryptocurrency-keys/"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.
A really good question is whether banks will be responsible for losses, provided that the encryption key is stored only by them and the user. For example, if the user intentionally gives the key to someone else, the person will be able to withdraw money in another country, and the user-the owner will say that the Bank could not implement the proper security and will require payment. This point will need to be resolved as soon as possible.
