TSETC: Design of an efficient trust-based security model with spatial & temporal consensus for blockchain-based deployments

Abstract

Existing Proof of Work (PoW) and Proof of Stake (PoS) consensus models, in particular, lack the resilience and efficiency necessary to meet today's high-speed, low-energy, secure, and robust data transaction requirements. These flaws have proven problematic, necessitating an urgent need for a more adaptable and resilient security model process. This paper proposes a novel consensus model that addresses these shortcomings by combining PoW and PoS consensus methodologies with Spatial and Temporal Trust Levels. During the block mining process, these levels are cleverly estimated by an advanced processing algorithm of miner node parameters, such as delay and energy requirements, throughput performance, Packet Delivery Ratio (PDR) performance, and jitter performance. The model surpasses its predecessors by adopting a proactive stance in order to anticipate and mitigate potential risks while simultaneously optimizing performance metrics. Several empirical findings demonstrate that the proposed TSETC model is superior in various respects. The model accomplished better speed, lower energy consumption, improved throughput, and improved PDR levels. In addition, it maintained lower jitter, even during attacks, in comparison to recently proposed models. In essence, this paper presents a paradigm shift in the security models of blockchain-based deployments by introducing a novel, adaptable, and efficient solution that significantly improves the overall system's resilience and performance. This innovative strategy promises a safer, more environmentally friendly, and more reliable future for blockchain technology applications.
