Abstract

A method and system is disclosed that enables suppliers, at every step of the build process, to perform a blockchain transaction to verify the validity of Vital Product Data (VPD) or firmware of a server chip, the system configuration, the uniqueness of the components and whether or not service procedures are followed.

Method and System for Verifying Distributed Processor Vital Product Data (VPD) and Maintenance Procedures via Blockchain Transactions

While purchasing distributed processors and other hardware and software products, there are many layers of suppliers over which a buyer company exerts no control and therefore there exists the possibility that processors are whitewashed, cloned or counter fitted somewhere along the supply chain. For example, a less offering processor has its firmware and vital product data (VPD) scrubbed, and is reprogrammed to report that it is in fact a much more expensive offering. Such actions de-legitimize and devalue the company as a brand and a server product. Further, the usage of non-standard and non-contractual service procedures is also a liability.

Thus, there is a need for a method and system that addresses the above mentioned problems.

Disclosed is a method and system that enables suppliers, at every step of the build process, to perform a blockchain transaction to verify the validity of the VPD or firmware of a server chip, the system configuration, the uniqueness of the components and whether or not service procedures are followed.

Every supplier has a vested interest in acting as a block-chain miner as they are ensuring the quality of the product that is to be shipped downstream. This decentralized verification, further, builds trust in boxes supplied this way, rather than relying on validation from a single player in all markets.

Considering a scenario of component white washing and unapproved service procedures, a company, beyond module assembly, does not have control over system builds and vendors.

The entities of the supply chain are the wafer foundry, the company, the system build vendors, retailers and service providers. Among these entities, there are a few that may follow the company’s procedures and contractual agreements or be involved in processor/component whitewashing or direct vio...
