Computation of containment relationships

A method, comprising:

• 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.

A non-transitory computer readable medium comprising instructions, that when read by a processor, cause the processor to perform:

• detecting an asset aggregation or disaggregation event;
• executing a single-shot update of an asset containment world-state at an ingestion of the asset aggregation or disaggregation event;
• determining 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.
