No, I didn't. The NFT would be stored on chain and inside the NFT would be hash of the data that is stored off chain. Anyone can then source the off chain data from any location and then compute the hash of that data and compare it with what is stored on chain.

This is no different than any other system. What makes that Oracle database that your property assessor uses to store your parcel information in enforceable? Oh yeah, the government.

You literally said all the data would be stored somewhere else. > This is no different than any other system. If this is no different than any other system, then it has no benefits of any other system. > What makes that Oracle database that your property assessor uses to store your parcel information in enforceable? Oh yeah, the government. Indeed, the government. Who makes your fantasy tokens referring to physical objects enforceable? Oh right. No one.
- ahnick 4y ago> Yes. You literally said all the data would be stored somewhere else. Meta data (ownership data) is stored on-chain. (supplemental data is stored off-chain) So again, no I did not say that all data is stored somewhere else. 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. Governments can choose to embrace a blockchain as their system of record. If they do, then NFT deeds are as enforceable as traditional property deeds. > Who makes your fantasy tokens referring to physical objects enforceable? Oh right. No one. 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.
- Yizahi 4y agoOwnership 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.
- ahnick 4y agoOwnership 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.
- illiarian 4y ago> 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.
