They won`t be so enthusiastic,when they find out how much it will cost to implement the blockchain technologies and much electricity will be consumed.Again,the only one,who is going to make the big profits from this treand will be the big online corporations.The tax payers will be ripped off again.

The application of blockchain that they'll use would probably not include bitcoin's traditional PoW scheme as you know it. Blockchain isn't limited to just coins and whatnot, it could also be used in logistics, banking and finance.. you name it. They'd be keen on developing such a tech considering how cheap and easy it is to implement and have a robust system compared to their obsolete systems which are, up to now, still prone to hacks and thefts. Blockchain might be the greatest innovation of the 21st century and might be the invention that the world is waiting to spark yet another industrial revolution.
