Abstract: 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.

Abstract: An example operation may include one or more of generating, by a first blockchain client, a transaction to a blockchain network to transfer a document, transferring over a private channel, by a second blockchain client, a first key to the first blockchain client, the private channel providing a point-to-point connection between the first and second blockchain clients, encrypting the document using a shared key, transferring, by the first blockchain client, the encrypted document over the private channel, generating, by the second blockchain client, a transaction to acknowledge receipt of the encrypted document, and transferring the shared key encrypted with the first key.

Abstract: 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.

Abstract: A user performing a first process on a first computing device is detected. The first process includes one or more discrete tasks. A process flow graph, that is generated before performance of the first task, related to the first process is retrieved based on detection of the first process. A user action that relates to the one or more discrete tasks of the first process is identified based on the first process and based on the process flow graph. A current state of the first process is determined based on the first process and based on the process flow graph. A first video is generated based on the current state of the first process and based on the user action. The first video depicts one or more future actions that may be performed by the user to successfully perform the first process on the first computing device.
