Multi-Objective Optimization for Enhancing Blockchain Scalability and IOT Security: A Comprehensive Approach

Creation of safe as well as decentralized networks is possible on through the combination of blockchain technology and IoT. However, because of the trade-offs between the latency, throughput, scalability and robust security within these systems remain a challenge. A novel multi-objective optimization technique is presented in this paper to improve the scalability and the security of the IoT devices. The strategy used in this paper is based on the advanced techniques of optimization like throughput, latency, cryptographic strengths of the transaction. So, a lightweight cryptographic technique for the security enhancement is incorporated with the layer 2 solutions for scalability, to allow limits of suitable IoT devices. According to the findings of the test, the method used in this paper helps in maintaining high level protection against the data breaches and threats while achieving an impressive improvement of scalability up to 50 % in the throughput of transaction. This article offers a thorough approach and practical answers to the solution of the twin problems of security as well as scalability.
