Nutrition data provenance ledger
Verify the source trail behind a generated nutrition output
Enter a provenance chain hash to check whether a nutrition output was issued by the local eNutritionFacts Tools Suite ledger and whether its verification status is still active.
Nutrition Data Provenance Ledger checks source hashes, parameter hashes, output hashes, and local signature status. It supports editorial verification; it is not a ranking guarantee or public blockchain.
