Author's position is that "haters" brought NoSQL down. (Side note - With this usage of "haters" I wonder if "critic" will ever be seen outside a dictionary).And same is happening with Blockchain. Too many critics. NoSQL proponents should help Blockchain because of the shared camaraderie of being a technology which were/are criticized heavily.
The main point of the article, like most in this space, is to re-define the word blockchain. What exactly is it? As per author it is byzantine fault tolerant state machine replication or BFTSMR. But there is not much to be said aside from the fact that "blockchain shouldn't be written off, just yet".
While agree on not writing off blockchain yet, I can't help but ask if blockchain solved BFTSMR - it happened over 9 years ago. And people/companies dint jump in until 1-2 years ago. So most of these people/companies are just following the hype train.
