Razormind, Ethereum, Eris Industries et al have been working on decentralized systems for nearly two years now. Eris released their DApp server for exactly this usecase and are working in the States to spread word of the tech. Ethereum recently pulled into release mode, and their decentralized system for smart contracts is slowly gaining momentum. Razormind has been working on a Decentralized Operating System which is driven by blockchains. The banks have only recently moved into the space properly - there was a $30m investment in Chain by Citi et al a few days ago - but folks like UBS and Barclays have been setting up blockchain labs and accelerators in London to investigate the possibilities.
