Abstract

The rapid expansion of the Internet of Things (IoT) into industrial, healthcare, and smart city domains has intensified interest in decentralized architectures, notably blockchain and peer-to-peer systems. While decentralized models offer notable advantages over centralized infrastructures—such as improved fault tolerance and enhanced data integrity—they also introduce significant scalability limitations and expose new vectors of security vulnerabilities in large-scale deployments. This paper explores the core scalability constraints, such as latency, throughput bottlenecks, and energy inefficiencies, while concurrently analyzing security concerns including consensus manipulation, Sybil attacks, and smart contract flaws. Through an integrative analysis, supported by published literature and illustrative diagrams, this study outlines how these challenges can be mitigated and maps future research directions for resilient and scalable decentralized IoT systems.
