Abstract

Integrity of a physical object is verified by receiving, data encapsulating a request to verify the integrity of the physical object. Subsequently, a data structure is accessed that includes a plurality of linked segments each characterizing an entity within a supply chain for the physical object. Each segment includes a respective predecessor field and a respective hash value. All of the segments can be iterated through in reverse chronological order to confirm, for each segment, whether a value for the predecessor field is equal to a hash value in a hash field in an immediately previously segment, the hash value being a hash of all values of the particular segment. Data characterizing the iteration can then be provided. Related apparatus, systems, techniques and articles are also described.
