US Patent 11379474 Computation of containment relationships

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.
