For oil and gas companies to adopt block chain technologies tells me that more executives and "older" decision-makers are grasping the potential usefulness. These companies aren't run by Millennials or Gen Xers. They
are controlled by people like me, middle aged and older, who take more time, generally, to adopt innovations. At the same time, oil and gas executives tend to be among the most intelligent "engineering-types", right? So they would be early-adopters for something as innovative and conceptual as block-chain. This tells me that we are at the beginning of seeing practical implementation of block chain technology at the corporate level.
