    Bitcoin (abbreviation: BTC; sign: ₿) is the first decentralized cryptocurrency. Nodes in the peer-to-peer bitcoin network verify transactions through cryptography Source

    But you’re kinda right with the proof-of-work. But I would consider sha256 as cryptography

      That’s like saying that you’re a English lord because you watched a TV show involving the middle ages one time. Just because a concept contains, as one option amongst many, a thing, doesn’t make that concept the thing.

      The proof of work could be anything- sha256 was just something that happened to be picked. That doesn’t make it cryptography any more than you could call RCS cryptochat.
