Blockchain is a shared, immutable ledger for recording the history of transactions. It fosters a new generation of transactional applications that establish trust, accountability and transparency. Cognitive technology and blockchain working together will emerge as the modern services platform.

"The ultimate competitive advantage will go to those who become a “cognitive business.”  I’m not talking about a technology, I’m talking about a way of doing business.  Cognitive technology is a silver thread through your business."
