The order number key function is identical to the letter of guarantee function
Your statements are highly misleading, to put it mildly. You must be well aware of the fundamental difference between a legitimately constructed, cryptographically signed, and publicly verifiable "Letter of Guarantee," and the arbitrary, random code generated by your system. There's no middle ground here: if you're aware of the difference, then you're blatantly lying to the community, and if you're not, then you're nothing but a bunch of incompetent amateurs who don't belong in this industry.
There are no additional risks for customers due to the order number key
That's not true either.
This is my Order number key:17u3HP95Zunjep6hpo3XRkTJJzdwUgkw. What exactly does it prove? How can I independently verify this?
