P2B-Trace: Privacy-Preserving Blockchain-based Contact Tracing to Combat Pandemics
Summary: Blockchain-backed decentralized architecture records an authenticated contact-event data structure, enabling verifiable integrity and preventing local tampering. A zero-knowledge proximity verification protocol preserves user privacy while proving proximity claims, with experimental cost analysis of tracing integrity. (summarized by gpt-5-nano on Feb 09 2026)
