MinervaLedger is designed around data minimization, controlled access, traceability, and interoperable architecture.

Principles
Minimize
Avoid duplicating full clinical records unless the workflow genuinely requires it.
Encrypt
Protect sensitive information in transit and at rest using appropriate technical controls.
Separate
Keep sensitive clinical payloads separate from immutable provenance mechanisms.
Govern
Connect selected data access to participant permission and workflow purpose.
Trace
Maintain evidence of important state changes and participant events.
Revoke
Design consent and authorization workflows around change, expiry, and revocation.
Blockchain architecture
The Blockchain Is Not the Medical Record.
Where distributed-ledger technology is used, MinervaLedger's architecture is designed for event provenance, timestamps, hashes, references, or permission events rather than placing complete clinical records publicly on-chain.
