Abstract: Techniques facilitating blockchain ledgers of material spectral signatures for supply chain integrity management are provided. In one example, a computer-implemented method comprises validating, by a device operatively coupled to a processor, spectral signature data associated with a material, resulting in validated spectral signature data; and generating, by the device, a set of information corresponding to a transaction of the material in a blockchain associated with the material, wherein the set of information is related to the validated spectral signature data. In some embodiments, the computer-implemented method further comprises authenticating, by the device, a first party device associated with a first party to the transaction and a second party device associated with a second party to the transaction and including identities of the first party and the second party as indicated by the respective party devices in the set of information.
