Abstract

This paper investigates the adaptation of blockchain consensus mechanisms to the specific requirements of IoT environments. The authors analyze common consensus models, including Proof-of-Work, Proof-of-Stake, and Delegated Proof-of-Stake, identifying their limitations when applied to decentralized IoT networks. The central contribution is a proposed consensus model that balances the trade-offs between node energy consumption, security, and network speed. Through a detailed analysis, the study explores how the network topology of IoT devices influences the efficiency of consensus. The paper concludes by outlining potential paths for future implementation, emphasizing the need for flexible, adaptive consensus mechanisms that can handle the unique dynamics of intermittent connectivity and variable device power in IoT ecosystems.
