Privacy Principles
Data minimization
Only collect what the workflow needs. Labbook evidence can remain private while public pages show summaries and hashes.
Self-custody wallet
The OSN Wallet encrypted keystore, wallet password, and private key remain in the user's browser and recovery file. OSN stores only the public address, ownership signature record, and verified on-chain activity needed for the selected service.
No raw sensitive data on-chain
Web3 records should store hashes, credentials, and attestations, not raw patient data, unpublished notes, or private files.
Role-based visibility
Project owners, reviewers, funders, and public users should see different levels of detail.
