Blockchain-IoT Driven Framework for Optimizing Custody Transfer and Commercialization in Nigeria's Natural Gas Pipeline Network
Nigeria, a leading natural gas producer in Africa, faces significant challenges in optimising its gas infrastructure to support efficient commercialisation, reduce resource wastage, and foster transparency in transactions. Current systems for custody transfer, contract enforcement, and payment reconciliation often suffer from inefficiencies, manual interventions, and lack of trust among stakeholders. This paper proposes a novel technical framework that leverages Blockchain and the Internet of Things (IoT) to address these challenges by digitalising the country's gas pipeline network. The proposed framework deploys IoT-enabled smart sensors at key custody transfer points across the gas supply chain to monitor critical parameters such as gas flow rate, volume, temperature, and pressure in real time. These parameters are securely stored on a blockchain network, ensuring data immutability, transparency, and auditability. Smart contracts integrated into the blockchain enable automated execution of contractual terms, including the initiation of payment processes via Enterprise Resource Planning (ERP) systems once predefined conditions—such as the transfer of an agreed gas volume—are met. This system minimises delays, mitigates risks of data tampering, and eliminates disputes between producers, suppliers, off-takers, and consumers by providing a single source of truth. Furthermore, the framework supports smaller producers by enabling fair participation in the market and providing a mechanism to monetise flared gas. The paper outlines the technical architecture of the proposed solution, including blockchain consensus mechanisms, IoT device integration protocols, and cybersecurity safeguards tailored to the Nigerian context. To validate the feasibility of this approach, the study examines key implementation considerations, including regulatory compliance, scalability, and integration with Nigeria's existing gas infrastructure. A comparative analysis with similar initiatives globally was conducted to highlight best practices and lessons learned. By demonstrating the potential for enhanced efficiency, accountability, and economic growth, this paper provides a robust pathway for transforming Nigeria's gas sector through advanced digital technologies.
