Physical object authentication using PUF and blockchain

Is anyone working on use of PUFs and blockchain to verify the origin of physical objects? Specifically use of craquelure or optical PUFs. Thank you.

I heard of someone… somewhere who was using a splatter of UV in, that can only be seen by a certain lenses of some sort to create a unique pattern.

the only problem is if that ink is permanent or could fade away and or change the pattern.

It definitely something that many people are NOT considering.
