This paper presents a new resilience optimal Byzantine consensus algorithm targeting consortium blockchains. To this end, it first revisits the consensus validity property by requiring that the decided value satisfies a predefined predicate, which does not systematically exclude a value proposed only by Byzantine processes, thereby generalizing the validity properties found in the literature. T...

In this paper, we propose a predictor-corrector type Consensus Based Optimization(CBO) algorithm on convex feasible set. Our proposed generalizes the CBO in [11] to tackle constrained optimization problem for global minima of non-convex function defined domain. As practical application algorithm, study portfolio finance. application, introduce an objective choose optimal weight each asset asset...

This paper opts to mitigate the energy-inefficiency of Blockchain Proof-of-Work (PoW) consensus algorithm by rationally repurposing power spent during mining process. The original PoW scheme is designed consider one block at a time and assign reward first place winner computation race. To reduce mining-related energy consumption, we propose compensate effort runner(s)-up round, granting them ex...
