Prem Naraindas of DXC Technology spoke at the Blockchain Summit in Sydney. Some key points from the document include: - Blockchain initiatives require identifying business requirements and stakeholder buy-in to ensure viability beyond just installing technology. - Most blockchain proofs-of-concept remain isolated experiments and few have advanced to live production systems. - Successful blockchain projects address strategic, financial and operational concerns and create new business models rather than just focusing on technology. - Many blockchain initiatives will fail because the business case is not identified upfront or projects become misaligned between vendors and customers.
