DPC-Sharding: Adaptive and Byzantine-Resilient Sharding for Dynamic Networks

This research presents DPC-Sharding, a framework that improves blockchain sharding (dividing a blockchain network into smaller processing groups) for unstable networks like IoT and edge computing systems. The framework uses formal safety guarantees and adaptive controls to maintain security and performance even when network conditions change rapidly or nodes frequently join and leave, addressing limitations in existing sharding approaches that switch between modes crudely or adjust thresholds using guesses.
