CHRONOS: Three-Layer Architecture Solves Stale Pricing, Privacy Budget, and Index Decay in Data Marketplaces

arXiv·medium signal

Temporal knowledge-graph data marketplaces face three coupled failures: stale index shortcuts reduce recall as edges evolve, stationary Shapley pricing misattributes value after distribution shifts, and uncoordinated agents over-consume shared differential-privacy budgets. CHRONOS provides a unified three-layer architecture with neural-ODE temporal decay, dynamic pricing, and coordinated privacy budget management across multiple agents.
