If so a blockchain of its own is needless "bloat"; one could simply offer customers a range of costs of existing, expected to be secure chains on which to record a cryptographic proof, no need to store entire object, owner of object can retain actual object / 3D-file as long as they feel they need, holding also along with it algorithm / program that creates the algorithmic proof given the actual file.

Some customers might choose to have their proof written to bitcoin blockchain, others maybe even also to various other chains as redundancy.

That's an arguable point, whether it is pointless to store. imho
In PoW miners are finding new blocks, but they store "nonce" one the blockchain (proof is part of the blockchain).
Every block represents a piece of value, as well as the user object in 3Dpass does.

Miners could have stored proof of work somewhere outside of the blockchain. Why didn't it work this way?

Let me put my two cents in by answering the question Roll Eyes

It didn't work because the network must take ultimate responsibility for each and every block/asset on the blockchain, which neither of single nodes/individuals can take. And this could not be fulfilled without having the whole bunch of data (proofs included) sealed into the Merkle tree. So it becomes irrefutable evidence proved by math.

The bottom line is that if we want the network to take responsibility for the asset authenticity, it must be stored on the blockchain and sealed into the block header by the block author. https://3dpass.org/features#ledger-why-1node-1vote

And if the asset owner takes 100% responsibility himself (no guarantee for public), he can store the object wherever he likes. Having the HASH ID (the object identity) stored on the blockchain would be enough in the case.

3Dpass consensus Proof of Scan is based on recognition function instead of regular hashing. So, the network is capable of the object properties processing and thus it can take responsibility for the object authenticity (not to mistake with the file authenticity). Which none of the existing L1 blockchain platforms can provide.

Thanks for backing me up! I was convinced, there were supposed to be something to it Grin
