“I’m interested in blockchain, not bitcoin.”
Admit it, you’ve heard this hundreds, if not thousands, of times. (You might have even said it yourself.) And sure, people know what you’re saying, you’re talking about the “technology underlying bitcoin” and you sound smart enough.
Once it became known – or at least presumed – that you could apply cryptography in finance, in ways similar to how it’s used in bitcoin, everyone started making sure that statement fell from their lips. And that refrain – kicked off by bitcoin itself – remains powerful today.
Sounds plausible? Sure. But, interestingly, the word “blockchain” doesn’t actually appear in the original bitcoin white paper, released back in 2008. Rather, the white paper uses the words “block” and “chain” separately many times.
It describes the word “block” as the vehicle for a bundle bitcoin transactions. Then, these blocks of are linked together, forming a “chain” of “blocks.”
