If the private key is inside of the note and stays the same when it changes hands, how do I know you did not make a copy of it when you created the note?

- paulgerhardt 7y agoAnother contributor here. This is one of the novel advancements made by Kong. Specifically, Kong notes use a secure element which 1) self-generates a key pair 2) can attest the key pair was self-generated and 3) does not leak the private portion of that key pair. Section 2 of the paper (specifically 2.2) goes into more detail[1].

- TekMol 7y agoSo your answer is "trust us". Because how would I know if the claims of the hardware manufacturer (you or your supplier) are true? This of course holds true for all hardware. When someone creates or stores a Bitcoin key on a laptop, they are at the mercy of the laptop manufacturer.
- Kuinox 7y agoThere is also a private key inside simcard, and debit cards. Good luck fetching it. I mean, you can technically do this, but it would be really hard.
- ccamrobertson 7y agoYes -- see section 2.3 in the paper linked for our discussion on this. The chips you're referring to are broadly considered to be "smart cards" and usually based on something like Java Card.
