Abstract

The growth of the Internet of Things (IoT) has connected a massive number of devices, but its common centralized design creates major security, privacy, and scalability problems that old security methods cannot properly fix. This review explores how Blockchain Technology (BCT) offers a new approach to create trust and strong security for IoT systems without a central authority. Following the PRISMA guidelines, this study analyzes 68 research papers and uses a Chi-square test to statistically confirm the link between IoT problems and the use of blockchain solutions. The results show a strong, statistically proven connection, with a Chi-square value of 34.772 (p<0.05) and a Cramer's V of 0.63. Key issues like data integrity, confidentiality, and device identity management are effectively solved by blockchain's features, including smart contracts. The paper also compares leading platforms—IOTA, Ethereum, and Hyperledger—evaluating their pros and cons regarding scalability, speed, and energy use for different IoT applications. This work provides a structured, evidence-based analysis of the Blockchain-IoT landscape, offering critical evaluation that goes beyond simple summaries. It also identifies future research directions, such as combining blockchain with Artificial Intelligence (AI), developing quantum-proof security, and creating universal standards to allow different systems to work together seamlessly.
