I am not sure how far the concept of Proof Of Work qualifies to be on topic with crypto.SE which is why I would like to ask recommenations here first.
The question is related to me not understanding how random data can or cannot be indexed in order to shortcut some Proof Of Work scheme and henceforth defeat it.
If not directly I possible on crypto.SE I would be very happy some advice which else site of the SE universe would seen a better choice.
Thank you
