Abstract: A method for tracking an item in a distributed environment is provided. At least one node in a network adds a new block to a first cryptographically verifiable ledger represented by a first sequence of blocks that is stored in one or more non-transitory computer-readable media. The new block added to the first cryptographically verifiable ledger contains a component identifier and a hash of a previous block in the first sequence of blocks. The at least one node in the network adds a new block to a second cryptographically verifiable ledger represented by a second sequence of blocks that is stored in the one or more non-transitory computer-readable media. The new block added to the second cryptographically verifiable ledger contains a destination identifier, the first sequence of blocks, and a hash of a previous block in the second sequence of blocks.

Abstract: Systems, methods, and machine readable media are provided for delivery verification. Delivery of a package is initiated by a courier by submitting an action to a distributed ledger. The courier records video of the delivery of the package to a customer site. The video of the delivery of the package is sent to a blockchain referenced by the distributed ledger. The video of the delivery of the package is added to the blockchain. The customer captures any motion detected video of the package occurring after delivery of the package by the courier and this video is added to the blockchain.

Abstract: A system and a method for the verification and visualization of subcomponents in a completed assembly is disclosed. The system receives upstream product component sourcing manifest from upstream source addresses. The system receives one or more downstream product component sourcing manifest from one or more downstream source addresses. The system generates a cryptographic verifiable ledger of transaction records based on the upstream and downstream manifests and upstream and downstream source addresses. The system propagates transaction records across a network. The system retrieves the records and instantiates a display tree graph structure based on the transactions in the master cryptographic ledger.
