Executives in Davos said they are now all about blockchain technology, proper controls and regulation, and the promise of disruption that it holds for financial services and beyond. Colm Kelleher, chairman of Swiss bank UBS (UBSG.S), told a WEF panel that blockchain technology will help reduce costs for banks. "We kind of dodged a bullet," Kelleher said, noting that the collapse in the value of crypto currencies had not caused systemic problems.
