A Hybrid PSO–GA Algorithm for Adaptive Decentralized Sequencer Selection and DAG-Aware Workload Coordination in Layer-2 Blockchain Networks
Decentralized Layer-2 sequencing requires fixed-size committees to balance performance, fairness, and resilience while downstream transaction tasks remain dependency-constrained. This study formulates committee selection as a bounded seven-objective discrete optimization problem and combines a feasibility-preserving hy...
