An example operation may include one or more of generating, by a blockchain node, an asset containment world-state by execution of a linear-time ingestion algorithm, detecting, by the blockchain node, an asset aggregation or disaggregation event, updating, by the blockchain node, the world-state based on the asset aggregation or disaggregation event, and computing supply-chain metrics based on the updated world-state.

Computation of containment relationships

An example operation may include one or more of receiving, by a processing node, a plurality of documents reflecting at least one action performed on supply-chain assets at a location of an asset supply-chain node, translating, by the processing node, the plurality of the documents into a plurality of entry and exit events of the supply-chain assets, and generating incomplete or non-chronological supply chain assets-related data based on the plurality of the entry and the exit events.

Computation of supply-chain metrics

An example operation may include one or more of receiving, by a first node, from a second node at least one document describing an action performed on assets of an asset supply-chain at a location of the second node, executing, by the first node, a smart contract to translate the at least one document into a standardized form of entry and exit events and to define containment relationship of the assets, and computing metrics on the asset supply-chain based on the standardized form and the containment relationship.

An example operation may include one or more of detecting, by a blockchain node, an asset aggregation or disaggregation event, performing, by the blockchain node, a single-shot update of an asset containment world-state at an ingestion of the asset aggregation or disaggregation event, determining, by the blockchain node, parent-child duration parameters for each instance of an asset parent-child association defined by the asset containment world-state, and executing a linear-time algorithm to calculate supply-chain metrics based on all combinations of the asset aggregation or disaggregation orderings based on the parent-child duration parameters.
