One more thing: you rely on A and B not keeping and later combining those private key parts.

You're right. I didn't mention it because I thought it's obvious, and unavoidable. Funded collectibles are just not compatible with "verify, don't trust".

That would require destroying the hologram?
Or the designer keeping the partials.

Person A makes one part, Person B makes the other part. They don't know each other's data, make the collectible coins, and sell them. Everyone's happy!
8 years later, Person A meets Person B again and start talking. Person A just got divorced and lost his house. B has gambling debts. They start talking about "what if...." and it turns out both kept a backup. They join forces and empty all collectibles they ever created.
There is no way to avoid this other than trusting both A and B.

My question is does your system keep/store any data?

The answer to this question doesn't really matter: you can't verify it. A honest person would say "no", but so would a scammer.

Being closed source, there is no way to validate what it does - so thst requires us to trust you and trust the creator.

Open source software doesn't help either: you still need to trust a person.

Technically, if theres only one private key that exists, and it sits under a hologram of a coin that you own, then the key is yours and yours alone - unlike an exchange that actually holds your btc for you.

Unfortunately theres no way to know this with certainty, so the sentiment here is correct.

Let's call it Schrödinger's key: it may be yours, but at the same time you may have nothing or someone else may have it too. You can't know for sure until you open the box.
