> Yes. You literally said all the data would be stored somewhere else. Meta data (ownership data) is stored on-chain.

The meta data that is stored on-chain serves an important role. > If this is no different than any other system, then it has no benefits of any other system. We are talking about the enforceability.

The government would in this particular case. Maybe in other cases it would be a company and in still other cases it could be an on-chain contract.

  Ownership data is not stored on chain because it is technically impossible. Chain only knows which wallet owns which URL-hash, and nothing else. Which real life person owns which real life physical or digital off-chain artifact (like deed, or picture, or a key), chain doesn't know and can't know. This info is stored in the centralised DBs managed my centralised entities like a company or government.

    Ownership data meaning the NFT itself and which can be proved by the holder using his/her private key. Off-chain data (such as personal information or supplemental documents) doesn't have to be stored in centralized databases. It could be stored in federated systems, or a local computer at the owner's residence, or a hosted server controlled by the owner. The chain can hold a hash of the identifying information and then an application can pull the data from wherever it is stored and referenced and check that is correct by recomputing the hash and comparing that to what is stored on chain.

      > Off-chain data (such as personal information So actual data that proves that this physical person is the owner of this physical asset. > It could be stored in a, b, c > then an application can pull the data from wherever it is stored Ah yes. Because when it's stored in a non-centralised database of "local computer at owner's residence" or "hosted server controlled by the owner" that data is easily accessible and retrievable.

        You can replicate it to multiple sources or use a decentralized storage solution if you are concerned about data availability.

        > You can replicate it to multiple sources Who is this "you" who is going to do that? Remember we were talking about property deeds? Their availability is of great concern. Before you answer that, go back over all your comments here and in other threads, collect all the limitations you've run into, all the workarounds you proposed, all the additional external systems you need to run just the most trivial of scenarios, and riddle me this: why would anyone want this?

      "federated systems, or a local computer at the owner's residence, or a hosted server controlled by the owner." That's just centralised in a different form. Or more precisely - not decentralised. Sure, some app can interact with centralised DB holding all actual information like deeds or music or whatever. Why do you need NFTs for that? Centralised BD must me utilised to track ownership of actual data or items by real people and it won't work any other way due to the IP rights and complex ownership agreements. NFTs are useless and impotent for this task.

    The blockchain is a piece of additive technology. It doesn't replace existing relational databases, nosql databases, object storage, etc. You can store data in any location you like (doesn't have to be a centralized location) and then verify it's authenticity later by recomputing the hash and comparing that to the hash stored on-chain in the NFT. Also, just because some data is stored off-chain does not mean you need to run your own infra. You could pay a hosting provider to operate it for you. Public permissionless blockchains help in easing the verifiability of ownership records, transfer of ownership records, and auditability of transactions. In the digital goods you don't necessarily have to rely on a single third party like a government.
