US Patent 11625731 Methods, systems and apparatus to track a provenance of goods

Methods, apparatus, systems and articles of manufacture are disclosed to track a provenance of goods. An example apparatus includes an unsigned block generator to generate a first unsigned block to store first processing data associated with the product by a first entity, a block signature engine to sign the first unsigned block with a first private key to generate a blockchain having a first signed block, the unsigned block generator to generate a second unsigned block in response to a second entity generating second processing data associated with the product by the second entity, the block signature engine to expand the blockchain by signing the second unsigned block with a second private key to generate a second signed block within the blockchain, and a blockchain validator to verify the product provenance by validating the first processing data and the second processing data using respective public keys associated with the first entity and the second entity.
