I did, and I appreciate the detailed explanation, yet from my limited technical understanding of dark skippy and cryptography/code in general, I cannot decipher whether the security architecture of the MK4 mitigates for it or not, albeit it is clear that there is incredible security built in to the device.
That said, I also don’t see anything in the article referencing the security architecture of the Coldcard Q, which is why I asked if it shares the same architecture as the MK4? Is there an article about the Q, and/or specifically about your thoughts on dark skippy/anti exfil?
I checked the website again and don’t see mention of Bluetooth so assume Q doesn’t use it, which I am happy about given this latest article 😅
