Two weeks of Proof of Blood. The idea: your biomarkers are your verifiable proof of health. Your data. Your keys. Your interpretation. Since I started this series: - Sovereign Health Intelligence is live at sovereignhealth.io - The code is open at github.com/nicksdigital/brickos - Sovereign Link is in development - 85+ biomarkers, encrypted at rest, protocol-aware I am speaking at BTC Prague in June. The talk: "Brick by Brick: Building Sovereignty in a Fiat World." Three ideas: 1. Convenience is the most effective form of control. 2. Health is not a lifestyle. It is infrastructure. 3. Sovereignty is a stack. Each layer is one brick. If you are at BTC Prague, come find me. I will have a live demo and would like to hear what you track and what tools you wish existed. If you are not there, the platform is open. Free tier available. Bitcoin accepted (5% off). Self-host for free, forever. Your body, your data, your server. Brick by brick. https://sovereignhealth.io https://brickos.io https://www.amazon.de/Brick-Building-Sovereign-Life-Bitcoin/dp/B0FR42K8R1 #proofofblood #sovereignty #btcprague #brickos #bitcoin #twentyonelife #brickos #proofofblood #btcprague #bitcoin #sovereignty #health

Every link you share goes through someone else's server. Bitly, TinyURL, short.io - they see every click, every referrer, every audience pattern. They know who clicked, when, and from where. Your link infrastructure is someone else's surveillance tool. And if you run a Start9 node, you know the problem: Tor onion addresses are 56 characters long. Unusable on a business card. Unusable in a QR code. Sovereign Link is the next brick in the BrickOS stack. A self-hosted URL shortener built for people who run their own infrastructure. The specs: - Single binary, under 20 megabytes - SQLite database, zero external dependencies - NOSTR NIP-98 login: your NOSTR keys are your identity. No email. No password. - Deploy on a VPS, Raspberry Pi, or Start9 node - Click analytics without surveillance: no raw IPs stored, SHA256 daily-rotating hash - QR code generation built in - Built in Rust, AGPL-3.0 The interesting part is the authentication. You log in with the same NOSTR keypair you use to sign notes. NIP-98 - cryptographic proof of identity. No accounts to create. No passwords to manage. Your NOSTR identity is your identity everywhere in the BrickOS stack. This is the pattern: every BrickOS application uses the same sovereignty primitives. NOSTR for identity. Self-hosting for data control. Open source for trust. Encryption for privacy. Sovereign Health for your body. Sovereign Link for your infrastructure. More bricks coming. https://brickos.io #twentyonelife #brickos #proofofblood #sovereignty #nostr #selfhosted #opensource

The sovereignty stack, bottom to top: Bitcoin - sovereign money. NOSTR - sovereign identity. Sovereign Health Intelligence - sovereign body data. Sovereign Link - sovereign infrastructure. Each layer: your keys, open source, self-hostable, no trusted third parties. Each brick you add, you remove one dependency on a system that does not serve you. Organizations invest millions in digital sovereignty. Sovereign clouds. Data residency. Vendor independence. Individuals deserve the same tools. Simpler. Open source. One Docker command away. Building sovereignty, brick by brick. https://brickos.io https://www.amazon.de/Brick-Building-Sovereign-Life-Bitcoin/dp/B0FR42K8R1 #proofofblood #sovereignty #bitcoin #nostr #brickos #twentyonelife #brickos #proofofblood #sovereignty #bitcoin #nostr #opensource

I would never ruin my steak 🥩 by adding greens! 🤣

GKI. Glucose-Ketone Index. Divide your glucose (mg/dL) by 18, then divide by your ketone level (mmol/L). Most people have never heard of it. But if you are on keto or fasting, it is the single most useful number you can track. GKI below 9: mild ketosis. GKI below 6: moderate ketosis. GKI below 3: deep therapeutic ketosis. GKI below 1: extended fasting territory. No health app calculates this for you. Sovereign Health Intelligence does. Automatically, from your glucose and ketone inputs. One number. More insight than a full lipid panel in isolation. https://sovereignhealth.io #proofofblood #health #gki #keto #biomarkers #twentyonelife #brickos #proofofblood #health #gki #keto #biomarkers #metabolic

In October 2024 I started tracking every biomarker I could measure. Blood glucose and ketones daily with a Fora 6 Connect device. Full blood panels every quarter. Blood pressure, weight, body composition weekly. 18 months and thousands of measurements later, here is what I learned. **1. Trends matter more than snapshots.** A single blood test is a photograph. Three blood tests over 9 months are a movie. I only understood my cholesterol trajectory after the third panel. One reading told me nothing. This is why Sovereign Health Intelligence tracks rolling averages, 7-day and 30-day views, and phase comparisons. A single number is not health data. A trajectory is. **2. Calculated markers reveal what single markers hide.** GKI (glucose-ketone index) combines glucose and ketones into one number. It told me more about my metabolic flexibility than either marker alone. Same with TG/HDL ratio for cardiovascular risk, and HOMA-IR for insulin resistance. SHI calculates these automatically from your inputs. The Fora 6 measures glucose and ketones. SHI calculates GKI. You measure triglycerides and HDL. SHI calculates the ratio. More insight from the same data. **3. Protocol context changes everything.** My LDL went up on carnivore. A standard app would flag it. But my TG/HDL ratio improved, my inflammation markers (CRP, IL-6) dropped, and my fasting insulin halved. The context changed the interpretation completely. **4. Your data changes the conversation with your doctor.** When I brought 18 months of glucose trends, ketone correlations, and inflammation markers to my doctor, the conversation shifted. Not "your LDL is high." Instead: "your metabolic markers look excellent." Your data. Your narrative. Not a snapshot someone else interprets for you. **5. A spreadsheet does not scale.** I hit 500 rows in month 4. Formulas broke. Charts were unusable. That was when I started building what became Sovereign Health Intelligence. You do not need my tool to start tracking. A notebook works. But if you want the calculated markers, the trend analysis, and the encryption, the code is open. https://sovereignhealth.io #twentyonelife #brickos #proofofblood #health #biomarkers #carnivore #bloodwork

Every morning. Same time. Same ritual. Fora 6 Connect device. One drop of blood. Six biomarkers in 30 seconds: glucose, ketones, cholesterol, uric acid, hematocrit, hemoglobin. Then I open Sovereign Health Intelligence and log the readings. The system calculates what the device cannot: GKI (glucose-ketone index), Dr. Boz Ratio, HCT/HB ratio. The Fora 6 gives me data. SHI gives me insight. 18 months of this ritual taught me more about my body than 40 years of annual checkups. You do not need expensive lab work to start. A home device and consistency will take you further than most people ever go. #proofofblood #health #biomarkers #fora6 #twentyonelife #brickos #proofofblood #health #biomarkers #fora6 #bloodwork

Sovereignty is not one thing. It is a stack. At the base: sovereign money. Bitcoin. You hold your keys, you control your wealth. No bank can freeze it. No government can inflate it away. One layer up: sovereign communication. NOSTR. You hold your keys, you own your identity. No platform can ban you. No algorithm decides who sees your notes. But there is a layer most Bitcoiners have not thought about: sovereign health data. I wrote about this in "Brick by Brick": the five pillars of sovereignty are Money, Health, Data, Attention, and Energy. The health pillar is the one we talk about least. And it is the one that affects everything else. A sick body creates high time preference. A strong body creates patience. You cannot think clearly about your financial sovereignty when your biology is working against you. Health is infrastructure. The sovereignty stack in practice: - Bitcoin: sovereign money - NOSTR: sovereign identity and communication - Sovereign Health Intelligence: sovereign body data - Sovereign Link: sovereign infrastructure Each layer follows the same principles: your keys, open source, self-hostable, no trusted third parties. I am building BrickOS as the platform for these applications. Each app is one brick. The philosophy from the book, turned into tools. The book: https://www.amazon.de/Brick-Building-Sovereign-Life-Bitcoin/dp/B0FR42K8R1 The platform: https://brickos.io One dependency replaced at a time.

When I showed my doctor 18 months of glucose trends, ketone correlations, and inflammation markers, the conversation changed. It went from "your LDL is high" to "your metabolic markers look excellent." One snapshot says: elevated cholesterol. Risk factor. 18 months of data say: TG/HDL ratio improved. CRP dropped. Fasting insulin halved. LDL went up because I eat animal fat, but every downstream marker improved. Context is everything. You need your own data to have a real conversation about your health. Not to fight your doctor. To collaborate with them. #proofofblood #health #biomarkers #carnivore #twentyonelife #brickos #proofofblood #health #carnivore #biomarkers #cholesterol

If you follow a ketogenic diet and track your blood ketones, every health app will tell you something is wrong. Ketone level: 2.5 mmol/L. Status: "Abnormally high. Consult your doctor." This is not a bug. It is a design choice. These apps use standard reference ranges designed for people eating the standard diet. On that diet, ketones above 0.5 mmol/L are unusual. On keto, they are the goal. The same problem applies to fasting. During a 48-hour fast, your blood glucose drops. Your app flags it red. But low glucose during a fast is expected. It means your body is running on ketones and fat. The system is working. I call this the "context problem." Health data without context is noise. The number means nothing without knowing the protocol. In my book I wrote: "Junk food is cheaper than real food, sickness is more profitable than health." The same incentive structure applies to health software. Generic reference ranges are cheaper to build. Context-aware ranges require understanding what the user is actually doing. That is why I built protocol-aware reference ranges into Sovereign Health Intelligence. You set your active protocol: standard, keto, carnivore, 16:8 fasting, OMAD, 48-hour fast, extended fast. The system adjusts its thresholds. A ketone level of 2.5 on keto? Expected. Green. A fasting glucose of 3.8 during a 48-hour fast? Normal. Green. No false alarms. No panic. Just context. 85 biomarkers. 8 health zones. Protocol-aware. Encrypted. Open source. Your body knows what it is doing. Your tracking tool should too. https://sovereignhealth.io #twentyonelife #brickos #proofofblood #keto #carnivore #health #biomarkers
