A computer device comprises a logic system and a computer-memory system operatively coupled to the logic system. The computer-memory system holds instructions that, when executed by the logic system, cause the computer device to instantiate a node of a blockchain having verifiable provenance. The blockchain includes a requestor block configured to specify at least one requested feature of a requested product and an offerer block cryptographically linked to the requestor block. The offerer block includes data obtained by automated testing of an offered product, which reveals the level of compliance of the offered product with respect to the requested feature through product feature life cycle of validation, test, verification and acceptance.
