Although Bitcoin is earlier than "blockchain", Bitcoin is the first application of blockchain, a perfect integration of theory and practice. Bitcoin is not a blockchain, but if the two are separated, no one will exist.
I'd be tempted to give you merits for your post if it didn't start off with seemingly nonsensical sentences like the ones above. Am I missing something? Bitcoin and blockchain technology were introduced simultaneously, right? Someone correct me if I'm wrong, because from what I've read, there was no such thing as a blockchain before Satoshi introduced bitcoin.
And bitcoin is just an application of a blockchain, so I'm not sure what you mean by your second sentence there. I just came to this thread to help out a member with a post history review but started reading other posts, and man....this section is going downhill fast.
