A decentralized, hardware-anchored consensus network for securely training and regulating medical artificial intelligence across multiple institutions. The system utilizes a provenance-linked aggregation engine that strictly accepts learning data only if it carries an unforgeable cryptographic seal generated directly at the medical sensor edge, blocking synthetic deepfakes. The aggregated global model is evaluated homomorphically against FDA Predetermined Change Control Plan boundaries stored in a global manifest lock. A distributed quorum of hospital hardware nodes must cryptographically vote to confirm the updated model's safety before deployment. Once a supermajority is reached, a multi-node safety synchronization deploys the update globally. A hardware-enforced global rollback circuit constantly monitors the network, capable of autonomously bypassing local operating systems to revert all hospitals to a previous model version if real-world performance breaches safety thresholds, ensuring absolute, verified regulatory compliance across the federated grid.
