Towards proof-of-prospect consensus mechanism for maximizing consumers' satisfaction in distributed energy systems

With economic prosperity on the rise, modern energy consumers are experiencing higher living standards and increasingly demanding greater satisfaction from energy systems, especially in scenarios involving risk.Satisfaction with risk decisions means consumers seek to make wise decisions when facing risks to optimize satisfaction.Yet, traditional optimization struggles with the increasing decentralization of energy systems, posing significant challenges to optimizing satisfaction with risk decisions.Blockchain technology, with its inherent decentralization, offers potential solutions to this challenge.However, blockchain systems encounter challenges in effectively integrating consensus mechanisms that optimize energy allocation.To fill this gap, a proof-of-prospect (PoP) consensus mechanism is presented in this paper, designed to enhance consumer satisfaction in the realm of risk decision-making.Recognizing that solutions are challenging to identify but straightforward to validate, the PoP substitutes the resource-intensive hash puzzle in the proof-of-work consensus mechanism with an optimization focused on consumer satisfaction.This shift not only boosts consumer satisfaction but also mitigates energy expenditure.Our findings indicate that in contrast to traditional consensus models, the PoP promotes fairness, decentralization, and reliability while improving consumer satisfaction and minimizing energy usage.
