Well I do think that it is both an evolution and a revolution.
Technically it is more like a evolution of a distributed database concept, but then much more advanced and for sure with the smart contracts it offers much more possibilities.
The crypotocurrency is the revolution, this is would change the way companies interact, people paying their bills and so on! The bank could be the next Blockbuster, but they won't. They could transfer this business model, to a more advanced and secure crypto wallet kind of business.
Also for lots of middle men, this could be a revolution because in same cases their reason for existence could vaporize over time!
Also we have to look at the human behavior. In most cases people don't want revolutions but do support evolution (if it comes to technology, not referring to a political evolution or revolution).
Can't watch the vid at work, so that will be for this evening.
Cheers,
Peter
