The disaggregated and multi-vendor nature of OPEN-RAN networks introduces new supply chain security risks, making equipment authenticity and integrity crucial challenges. Robust solutions are needed to mitigate vulnerabilities in manufacturing and integration. This paper puts forth a novel blockchain-based approach to secure OPEN-RAN equipment through its lifecycle. By combining firmware authentication codes, a permissioned blockchain ledger, and equipment node validators, we architect a tamper-resistant ecosystem to track provenance. The outlined design, while conceptual, establishes a foundation and roadmap for future realization. Through careful implementation planning, development of core components like firmware signed hashes and smart contracts, and rigorous performance evaluation, this paper can evolve from concept to practice. There is a vivid potential to make OPEN-RAN supply chains corner to corner secure, igniting further research and real-world deployment.
