Blockchain appears to be racing through an emotional cycle of initial excitement, hyper exposure, rapid (sometimes desperate/random) searches for application, and now possibly 'blockchain fatigue' as this article suggests. 

It seems a shame that we can't take a requirements centric approach, whereby we calmly consider blockchain as one of a range of solutions to a problem or opportunity. In many circumstances the 'one version of the truth' that blockchain promises can be delivered through other methods. But blockchain has huge potential - it would be a shame if we left it behind before the right problem found it at the right time.
