Trustable delivery of a product uses a package with a printed label having a unique product ID, an RFID marker applied to the product that contains the ID, and a smart chip inside the product that contains the ID and a digital key. The ID from the RFID marker is compared to the label for initial validation of the package. The smart chip is further interrogated to generate an encoded value of the ID, such as a hash value, using the digital key. The hash value is then used to authenticate the ID, thereby verifying that the product as delivered is the original, untampered product. The product ID and the hash value are recorded in a blockchain ledger associated with the product. In this manner, the packaged product can be validated by any party in the delivery chain, e.g., manufacturer, seller, distributor, delivery service, and final recipient.

Trustable product delivery with RFID and smart chip

An example operation includes one or more of selecting, by a trust maintainer node, at least two blockchain nodes to be assigned as non-human intelligent nodes controlled by separate consortiums, identifying, by the trust maintainer node, a plurality of blockchain nodes that are not assigned as non-human intelligent nodes, assigning, by the trust maintainer node, a trust value to each of the plurality of the blockchain nodes based on voting histories of each of the plurality of the blockchain nodes to determine an overall trust value of a blockchain, and responsive to the overall trust value of the blockchain being below a minimum threshold, selecting at least one node from the plurality of the nodes to be assigned as the non-human intelligent node to increase the overall trust value of the blockchain.
