Our solution is the fingerprint, a unique ID assigned to each product. Each fingerprint has a matching product_id, a string representing each unique item. Fingerprints are assigned to products before the TNFT is minted, and tokenIds are mapped to the fingerprint after minting. Fingerprints and tokenIds continue to remain consistent through fractionalization. Fingerprints tie all of our available stock (owned, fractionalized, and unowned) to the correct market price and metadata. There can be multiple tokenIds mapped to the same fingerprint; for example, three 100g gold bars may share one fingerprint, but each would be represented by a unique token.
