Major banks and mainstream financial institutions are warming up to the blockchain technology that powers Bitcoin, and launching internal experiments and pilot projects to find out how they can use the blockchain.
However, most banks frown at the chaotic anarchy of public “permissionless ledgers” like the Bitcoin blockchain, where any individual anonymous user can join and contribute hashpower to verify transactions without having to ask anyone’s permission. Instead, they would prefer “permissioned ledgers” owned and by the banks, which can be operated only by vetted players. Think of “BankCoin” blockchains that only the banks and the authorities have access to.
Since this trend appears to be rising fast, many startups are developing infrastructures for permissioned ledgers.
