In this video, I discuss Satoshi's real innovation, which is combining blockchain with distributed proof of work. Blockchain by itself is not very interesting.

Blockchain provides a way of showing if the history of transactions has been tampered with. But only by adding in proof of work do you make it impossible to edit the history of transactions, thus ensuring the immutability of the ledger.

Satoshi's genius was combining blockchain, distributed proof of work, a network of nodes, public/private key cryptography, etc.

People who say "blockchain, not Bitcoin" are either altcoin scammers or people who simply don't understand what a blockchain does.
