Blockchain Security Implementation using Python with NB-IoT deployment in Food Supply Chain

Both academia and Industrialists are paying keen attention to the Narrow Band Internet of Things (NB-IoT) developments in the modern era. While the Narrow Band Internet of Things is gradually being adapted for commercial purposes, it continues to raise a slew of security concerns, including those around authentication and privacy. Because blockchain technology incorporates a framework for maintaining confidence, auditing, and openness, it can be a promising tool for ensuring the Network's data exchange is secure. To enhance the level of security afforded narrowband data and to maintain their accuracy and transparency. We leverage the advantages of blockchain technology with Narrow Band Internet of Things (NB-IoT) with Food supply chain management. The system identifies the damaged agricultural product during the transportation between the Manufacturer to the Retailer and executes the python program to find the damaged product during the transportation that is used to authenticate data and generate the blockchain our scheme is deemed to possess attractive confidentiality, authentication, accountability, and quality characteristics, rendering it an ideal method for secure transportation with traceability future added in all-time possible in a decentralized and distributed manner using sha-256 secure algorithm in blockchain technology and narrowband internet of things.
