Researchers have introduced VISTA, a novel decentralized machine learning algorithm designed to function effectively even when adversaries control a majority of the worker nodes. The system operates on an incentive-based framework, rewarding only mutually consistent reports to transform adversaries into rational agents who balance corruption against potential reward loss. VISTA adaptively adjusts its acceptance threshold using optimization history, demonstrating improved convergence over static methods and retaining asymptotic convergence properties similar to standard SGD without requiring an honest majority.
