Development of a Robust Attack-aware Consensus Model for Context-Aware Blockchains
Smita Rajesh Kapse, Latesh Malik · 2023
Blockchain technologies have seen widespread adoption across various domains, necessitating a robust, efficient, and secure consensus mechanism that can operate under diverse conditions. This paper presents design of an innovative approach by integrating Proof of Temporal Trust (PoTT) and Proof of Spatial Trust (PoST) to formulate an "Attack-Aware Consensus Model for Context-Aware Blockchains (CAB)." Our novel framework addresses two critical dimensions in blockchain operations: temporal and spatial trustworthiness. PoTT evaluates miner performance based on historical metrics such as mining delay, energy consumption, and throughput, ensuring optimized resource allocation and efficiency. PoST, gauges the resilience of miners under security threats like Man-in-the-Middle (MITM), Sybil, Finney, and DDoS attacks. The fusion of these proofs of trust offers a holistic, resilient, and high-performance consensus mechanism that adapts to both the temporal and spatial context of blockchain operation.
