A patient's medical history should not be a raw file copied endlessly across hospital databases. In the Foundation Federation, it travels as a sealed mathematical proof, governed by the patient's Digital Twin. The hospital does not own the data. They only request access to it.
The Patient Journey
Step 01
Sovereign Record
The patient's Digital Twin holds their complete medical history — diagnoses, medications, allergies, imaging. Midnight-anchored. No institution owns it.
Step 02
Temporary Access
When visiting a new specialist, the Twin grants rights-bound access via a PACT SOW. The specialist receives the verified intelligence needed for treatment, not the raw underlying files.
Step 03
Automatic Expiry
Consent is time-limited. When the treatment window closes, the PACT contract expires. Access is automatically revoked. The hospital's system deletes the temporary keys.
Midnight Anchor
Consent is on-chain, revocable, and time-limited. The PACT contract enforces the expiry.
The patient retains absolute sovereignty over their intelligence, secured by Midnight.
