Galeon

Galeon is a data collaboration platform for healthcare that lets multiple hospitals train medical models jointly without moving patient records. Medical data is constrained by privacy regulation and institutional boundaries, and centralized pooling requires cross-institution record transfer with long approval chains and a broad leak surface. Galeon uses a swarm learning architecture: training code and data stay on each hospital's local node, nodes upload only model parameter updates, and a blockchain records node identity, training rounds and aggregation results, while participants define contribution and access rules through smart contracts.

It is therefore positioned as data infrastructure at the intersection of healthcare and decentralized science rather than as a general chain application. Verifiable product forms include joint modeling deployments for hospitals and research institutions and a health data management app for individual users. Network scale is measured by the number of participating medical institutions rather than by on-chain asset size.
