I thought the blockchain technology had the potential to help financial sector. Not the virtual currency itself but there are a lot of agreements, transactions and settlements which are done in a untrustworthy environment which makes it slow and resulting in settlements [0]. I thought this is also the reason why it takes so long to transfer money from one bank to another. I thought these processes could benefit from blockchains and smart contracts. Basically speeding up the whole process not requiring the banks to trust anyone [1].
