In this episode, former Express Scripts COO Neal Sample and Mastercard President of Operations and Technology Ed McLaughlin offer a point/counterpoint on blockchain. Neal argues that there is no use case for which blockchain is an optimal solution, and that no matter the problem an enterprise is trying to solve, a better technology likely already exists. In many cases, he says, executives often look to blockchain because of the hype more than anything. Ed agrees that enthusiasm runs amok when people use blockchain to get funded or just to use it. However, Ed considers himself a highly skeptical and jaded enthusiast, and argues that blockchain can be useful, especially when dealing with trust across enterprise boundaries.
