  • bob45885 bob45885 Excellent presentation, but slide 61 is where Mr. McNally got it wrong.

    The Bitcoin Address is NOT the Public Key. It's not even the same length as the Public Key. For a high-level audience, this is a reasonable simplification, but it's just non-factual.

    There are three numeric pieces to Bitcoin. The Private Key, the Public Key, and the Bitcoin Address. The Bitcoin Address can be derived from the Public Key (but not vice versa). And the Public Key can be derived from the Private Key (but not vice versa).

    The Public Key is revealed when you spend money. That is one of the reasons not to re-use Bitcoin Addresses that you have spent from, and to return your change back to a fresh address. (Another reason is to help with anonymity.)

    Just take 'Public Key' off this slide, and you're all set.
