Well the Blockchain technology helped solve a computer science problem called "The Byzantine Generals' Problem" so I would say the hype is real.
Well first, that has nothiung to do with blockchain concepts, but it is a Bitcoin problem.
I'm not sure it has solved that problem. If you believe that block generation times are too long, but they cannot be reduced because of disruption to the blockchain recording process, and you believe that long transaction confirmation times will lead to a drift away from Bitcoin, then it would appear that the BGP is still present as a problem.
