Banks have shown a keen interest in Bitcoin technology over the years. Various patents have been filed by these financial institutions to explore new potential business use cases. JPMorgan was recently awarded a patent which could allow the bank to issue blockchain-based virtual depository receipts.
With so many banks exploring opportunities in the world of blockchain, a lot of new use cases and products could be unlocked in the near future. Whether or not any of those potential use cases will be commercialized is a different matter altogether. There is still a lot of hype associated with blockchain technology and very little to show for most efforts as of right now.
