Great read on blockchain and Banks!
There’s a conundrum concerning blockchains: Bitcoin bundled together various existing technologies in a unique fashion to create something genuinely new — an almost unhackable, replicated database with no master server, via updates which are based on quickly verifiable effort rather than permission. Blockchains (permissioned chains) remove the genuinely new bit, but they are the current focus of activity in the Financial Services sector. Why? This created the incentive for strategic investment to look into blockchain applications. These replace banking infrastructure providers with software that doesn’t need to be run by a separate entity (e.g. SWIFT), and lower internal costs but still keep the requirement for trusted entities (banks themselves).
