Blockchain-NFV for Smart Digital and Secure Physical Structures in E-Government, Healthcare, and Network Systems

This paper proposed a combined model that melds Blockchain technology with Network Function Virtualization (NFV) to promote many areas, such as smart, secure, and scalable physical and digital infrastructures in E-Government, Healthcare, and Network Systems. The model treats the principal objections in conventional systems, including centralization, slowed service deployment, and restricted safety. By employing decentralized Digital Identity Decentralized identifiers (DIDs), smart contracts, and Virtual Network Functions (VNFs), the system guarantees boosted trust, auditability, and elasticity. The quantitative outcomes observed in the experiments showed a highly significant improvement. The review demonstrated a 46% reduction in access time, while the transaction throughput rate increased by more than 140%, exceeding previous efforts, and an 80% reduction in deployment time for service. Applying the model in the health care domain shows an overall session duration drop from 22 minutes to 6 minutes, resulting in an improvement of 73% overall. The reliability metrics assessment for the overall review resulted in a reliable classification of 5 out of 5 for the overall assessment based on our results, data integrity, conformance to terms of service, and resistance to attacks. Given all of the above, the presented model is identified as a promising environment for future digital transformation in terms of assuring security, capacity, and adaptability for critical issues.
