Decentralized Medical Data Sharing with Off-chain Storage and View-based Access Control

In briefDecentralized medical data sharing system using off-chain storage and view-based access control

SummaryThis paper proposes VASCO, a decentralized medical data sharing system that does not rely on a central server, a specific cloud storage such as IPFS, or a secure channel. It encrypts both data and metadata end-to-end, using eight chaincodes built on view-based access control. The authors report scalability tests on a 21-peer blockchain and interoperability checks across 30 combinations of standards, formats, and protocols.

BE-CTDE: Blockchain-Enabled Multi-Agent Reinforcement Learning with Anomaly Detection and Token Economics

In briefBE-CTDE: Blockchain-based multi-agent learning with anomaly detection and token incentives

SummaryThis paper proposes BE-CTDE, a framework that uses blockchain as a training-management layer for multi-agent reinforcement learning. A behavioral verifier compares executed trajectories with shared-policy recommendations, and token mechanisms (slashing, burning, rewards, compensation) adjust each agent's influence on the global policy update. In multi-agent path finding experiments, it achieves higher success rates under attack, even when adversaries are a majority, with collision rates up to 35% lower than detection without economic consequences and up to 43% lower than conventional stake slashing.

Securing Edge & Physical AI: Post-Quantum IoT Blockchain for Mission-Critical Cyber-Physical Agents

In briefPost-quantum IoT blockchain for securing edge and physical AI agents in critical systems

SummaryThis paper addresses the risk that quantum computers could break public-key authentication used in distributed cyber-physical systems and edge AI. It introduces rotational secrecy, an architectural goal that limits key exposure through authenticated transitions between cryptographic epochs, and presents PARS, a mechanism for coordinating key establishment, rotation, and reconciliation among agents. It also describes PARS-ESL, an optional permissioned ledger that records only security state such as key epochs, membership, and revocation, not high-volume operational data. The authors conclude that ledger-assisted post-quantum key-epoch management is feasible for selected edge AI and CPS security-control workloads under stated assumptions.
