If such a medal is ever to be awarded, the algorithm will need a lot of work to identify and locate intended recipients. One question I would add to the list of Qs I already posted, would it be awarded posthumously, because that is another can of worms.
I saw mention that it might be purchased rather than awarded. Even then, depending on the algorithm, the authentication process will be time consuming, unless you just take someone's word for it, and wearing a medal that you had to buy just doesn't sit right with me.
