...what I have understood is that bitcoin isn't a good invention, but it's a good innovation...
The blockchain man, it is a fucking
invention, the world had to wait 30 years for this one after public key cryptography was invented.
While I agree, that blockchain is the part that could be classified as an invention the most. Then I still have to say that I see it more as an innovation, because it is built on already created inventions in cryptography. I think that blockchain is a great innovation, but I also think that it will be as great of an innovation in the future as iPhone1 is right now.
