Note from the CEO: Digital cash! Getting closer and closer to being able to totally get rid of paper money. Santander has been working on a public ethereum blockchain that can digitize cash.

Revealed today during a panel talk at Devcon2 (an Ethereum conference being held in China) by Ether.camp founder and ethereum Java client developer Roman Mandeleil, the news was confirmed by representatives of Santander.
