Bitcoin introduced Proof of Work. A system where you prove value through verifiable effort. No shortcuts. No trusted third parties. Just math and energy.
Health needs the same thing.
We trust doctors with our diagnoses the way we once trusted banks with our money. We hand our health data to apps the way we once handed our Bitcoin to exchanges.
And we get the same result. Lost data. Misread signals. Decisions made for us, not by us.
I wrote about the Five Pillars of Sovereignty last year. Money. Health. Data. Attention. Energy. The health pillar was always the most personal. Because you cannot outsource it. You cannot delegate your metabolism to an app.
Proof of Blood is the practice: your biomarkers are your verifiable proof of health. Not a doctor's opinion. Not a generic app's interpretation. Your data, measured by you, encrypted with your keys, stored on your terms.
I have been tracking over 85 biomarkers for 18 months. Blood glucose, ketones, cholesterol panels, inflammation markers, hormones, liver enzymes. I started with a spreadsheet. Then I built the tool that should exist.
Sovereign Health Intelligence. Open source. Self-hostable. AES-256-GCM encrypted at rest. Zero knowledge - even the server admin cannot read your measurements.

This is the first in a daily series. Over the next two weeks:
- Why health apps lie to you about your ketones
- The sovereignty stack: Bitcoin, NOSTR, and your body
- Self-hosting your health data
- What 18 months of tracking actually taught me
- Building sovereign infrastructure, brick by brick
Your body, your data, your server.
