Brick by Brick: Building Sovereignty in a Fiat World

Standing on the stage at BTC Prague 2026, I spoke about a topic that extends far beyond Bitcoin.

We often discuss sovereignty at the level of nations and enterprises. Governments seek sovereign infrastructure. Companies seek sovereign cloud, data, and AI capabilities.

But what about the individual?

My keynote explored a simple idea:

True sovereignty starts with the individual.

Not through revolution.
Not through politics.
Not through waiting for someone else to fix the system.

But through small, deliberate actions:

🟧 Taking responsibility for your health
🟧 Protecting your attention from endless noise
🟧 Building financial resilience
🟧 Reducing dependency on centralized systems
🟧 Choosing signal over distraction

Sovereignty is not a destination. It is a practice.

You don’t leave the system overnight.

You simply begin building something stronger.

Brick by brick.

Thank you to everyone who attended the session at BTC Prague. The conversations afterwards were every bit as valuable as the presentation itself.

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.

Every link you share goes through someone else's server. ...

2026-04-26T10:00:00Z

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.

2026-04-23T10:00:00Z

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.

Sovereignty is not one thing. It is a stack. At the base: ...

2026-04-19T10:00:00Z

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

2026-04-06T13:00:03Z

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.

Most health apps run on fiat principles. We built Sovereign Health on Bitcoin principles.

You can pay with Bitcoin over Lightning. Instant. Borderless. No intermediaries. And yes, you even get a discount for it.

But this is not just about payment.

It is about mindset.

Bitcoin taught me one thing. Don’t trust, verify. That applies to money. And it applies to health.

Own your keys. Own your data. Verify your health with real measurements, not opinions.

No lock-in. No hidden systems. Just transparency and control.

🩸 Proof of Blood meets Proof of Work

If you are a Bitcoiner, you already understand sovereignty. Now apply it to your body.

Most people think health is about feeling good. I measure if my structure holds.

Bones, muscles, connective tissue. This is your foundation.

With Sovereign Health, I can see my structural health as a system. Not just weight or BMI, but body fat, hydration, bone mass, protein status, and key lab markers like creatinine and albumin.

The result is clarity. Where am I strong? Where am I borderline? Where do I need to act?

No guessing. Just data in context.

Bitcoin taught me one thing. Don’t trust, verify. So I built the same principle for health.

🩸 Proof of Blood

If your structure is weak, everything else will fail. Start measuring what actually supports your body.

Most people guess their health. I verify mine.

This is Dr Alex inside Sovereign Health, an AI that analyzes my blood markers in the context of my diet, my fasting protocol, and my trends over time. Instead of generic advice, it gives me explanations based on my own data.

The result is simple. My glucose is stable, an outlier is clearly explained, and my insulin sensitivity is excellent. No averages, no assumptions, just data.

Bitcoin taught me one thing. Don’t trust, verify. So I built the same principle for health.

Your data stays anonymized, but your insights become deeply personal.

Most people rely on scattered reports and disconnected apps. I bring everything together.

With Sovereign Health, I can import my lab results from providers like Synlab or track my biomarkers directly from my own devices. Blood tests, body composition, blood pressure, heart rate. Everything in one place, over time, in context.

This is where real insight starts. Not with a single report, but with continuous data you actually understand.

Bitcoin taught me one thing. Don’t trust, verify. So I built the same principle for health.

Your data stays yours. Your insights get better with every measurement.

Most people look at blood results in isolation. I look at context.

With Sovereign Health, Dr Alex does not just analyze numbers. It understands what is behind them. Your medications, your supplements, your protocol.

You can simply import your supplements or medications with a photo. The app extracts the ingredients, stores them, and connects them to your biomarkers.

Now your data starts to make sense.

Why did a value change
Was it diet
Was it a supplement
Was it something else

No guessing. Just context.

Bitcoin has Proof of Work. After 15 months of tracking every biomarker in my body, I now have Proof of Blood.

In January 2025 I went full carnivore. Not for medical reasons - out of curiosity. I tracked weekly: ketones, cholesterol, uric acid, hematocrit, hemoglobin, weight, body fat, muscle mass. Across 3 devices. In 3 separate apps. With zero way to correlate the data.

So I built my own platform. In 15 days. With AI.

108 biomarkers. 8 health zones. AES-256-GCM encryption at rest. 35,000 lines of Rust. Open source. This is not vibe coding. This is human-in-the-loop AI engineering.

Free to try: https://sovereignhealth.io

Bitcoin has Proof of Work. After 15 months of tracking every biomarker in my body, I now have Proof of Blood.

In January 2025, I decided to go full carnivore. Not because of a medical condition, out of pure curiosity. Can we survive without carbohydrates? Can we thrive?

15 months later, I feel like I'm 20 again. But this article isn't about diet advice. It's about what happened when an analytical mind met fragmented health data, and what AI-assisted engineering made possible in 7 days.

The Problem: Three Apps, Three Silos, Zero Insight

To back up my experiment with real data, I started testing my biomarkers weekly. Cholesterol, ketones, uric acid, hematocrit, hemoglobin, weight, body fat, muscle mass, the full picture, every week since January 2025.

The problem? Three different measurement devices, three different apps, three isolated data sets. Valuable health data, locked in silos with no way to cross-reference or correlate.

I started with what every data person starts with: a spreadsheet. Formulas, conditional formatting, color coding. It worked, but it was tedious and didn't scale.

Then I tried ChatGPT. I'll be honest, the health analysis was genuinely helpful. More useful than what most doctors have time to provide, and available 24/7. I could discuss scenarios, ask follow-up questions, iterate.

But then it hit me: I was feeding my most personal data, blood work, body composition, health history, into a system with zero GDPR guarantees. My data was being stored somewhere I couldn't audit, couldn't encrypt, couldn't delete.

That was the wake-up call.

See content credentials

The Spark: What If I Built This Myself?

Working in a digital-first company like Accenture that embraces AI from day one, I see every day how AI accelerates complex engineering projects. So I asked myself: what if I applied the same approach to my own problem?

I started with OpenClaw, an interface for Claude AI, to turn my biomarker tracking table into a proper specification. Back and forth, refining requirements, adding features, specifying the technology stack. After 5 days, I had a complete functional and non-functional requirements document, ready for implementation.

What I had specified was not a simple tracker. It was an enterprise-grade, privacy-first health intelligence platform. And the spec was detailed enough to hand directly to an AI coding assistant.

7 Days: From Zero to Full Platform

I used Claude Code to set up the development environment. Rust backend, CI/CD pipeline, GitHub integration, server deployment, all dependencies. Day one went nearly flawlessly.

What happened over the next 7 days still amazes me. I built the complete backend, frontend, and marketing website. Not a prototype, a production-ready platform. (link below)

Here's what "production-ready" means in numbers:

over 100 biomarkers across 8 health zones (metabolic, cardiovascular, immune, hormonal, cognitive, nutritional, structural, detoxification)

8 calculated markers derived automatically: GKI, Dr. Boz Ratio, HOMA-IR, TyG Index, BMI, WHtR, TG/HDL Ratio, HCT/HB Ratio

13 diet protocols (carnivore, keto, OMAD, paleo, Mediterranean, and more) with 7 fasting patterns

Dr. Alex - an AI health assistant with 8 specialist modes for labs, trends, diet, supplements, and protocols

Multi-tenant architecture - doctors, clinics, and families can run their own white-labeled instance

Multi-language support (English and German), with full GDPR and HIPAA audit reporting

Automated sprint planning and CI/CD - 7 sprints completed, 57 commits in Sprint 001 alone, 826 files touched

35,000 lines of Rust code, 117 SQL database migrations, 500+ frontend test files

I felt like the development manager of an entire department where every team member worked 24/7. Three more days of cleanup and fine-tuning, and Sovereign Health Intelligence was live.

This Is NOT Vibe Coding

I've had this discussion a few times already, so let me address it directly.

This is not vibe coding. I'm not dragging and dropping pre-built components in a web tool. I'm not configuring workflows in a no-code builder. There's no magic "generate my app" button.

This is raw, high-performance Rust code (Actix-web 4). A Next.js 16 frontend. A PostgreSQL 16 database. Every measurement encrypted with AES-256-GCM at rest, not just in transit. Row-level security enforced on 15 database tables. Even the server administrator cannot read your health data. Fully encrypted Blob storage and more for selfhosting on Start9 Server is on the roadmap.

I was the human in the loop. Every architectural decision (adr full log), every security design (full log), every feature prioritization, that was me. The AI was the accelerator. I was the architect.

The entire codebase is AGPL-3.0 licensed. Every line is auditable. Every encryption claim is verifiable. That's not something you get from vibe coding.

Why Sovereignty Matters

This project didn't come from nowhere. I wrote a book called "Brick By Brick - A Sovereign Life with Bitcoin" about owning your financial infrastructure. Sovereign Health Intelligence is the health chapter of that same philosophy.

Own your money. Own your data. Own your health records.

The platform is self-hostable via Docker, run it on your own server, your own VPS, your own Raspberry Pi. Payments are accepted via Stripe and Bitcoin Lightning. The code is open source.

Your body, your data, your server.

Bitcoin gave us Proof of Work. Now I have my Proof of Blood, 15 months of weekly biomarker data, encrypted, sovereign, and mine.

Lessons Learned

1. Data without analysis is noise.

Three apps gave me data. One platform gave me insight. Collecting biomarkers is step one, correlating them across health zones is where the value lives.

2. AI is a force multiplier, not a replacement.

Claude Code wrote the Rust. I made every architectural decision. The human-in-the-loop is not optional, it's what separates engineering from generated output.

3. Privacy is a foundation, not a feature.

The moment I realized I was feeding my blood work into ChatGPT with no GDPR guarantee, I knew I had to build something different. Encryption at rest is the minimum, not the ceiling. Anonymizing data before feeding an AI is a must have.

4. Specification before speed.

5 days on a proper spec with OpenClaw saved weeks of rework. AI can generate code fast. Without clear requirements, it generates the wrong code fast.

5. Open source is accountability.

AGPL-3.0 means anyone can verify the encryption claims, audit the security model, and fork the project. Trust, but verify, starting with the code.

6. Start with your own problem.

The best tools come from genuine frustration, not market research. I built this because I needed it. That's why it works.

Try It Yourself

Sovereign Health Intelligence is live and free to use.

For readers of this article: reach out to me directly for a 50% discount code on any paid tier. If registered by the end of April you get a full license tier upgrade for free.

What would you build if you had 15 days and an AI pair programmer?

Summary

Started carnivore in Jan 2025 out of curiosity, now 15 months in, tracking 108 biomarkers 6 of them weekly across 8 health zones

Frustration with 3 siloed apps and GDPR-blind AI led to building my own platform

Used OpenClaw + Claude AI for a 5-day specification, then Claude Code for 7 days of implementation and 3 day clean-up

Result: ~35,000 lines of Rust, 117 migrations, 500+ frontend tests - enterprise-grade, encrypted, open source

This is human-in-the-loop AI engineering, not vibe coding: raw Rust, AES-256-GCM encryption, row-level security

Today is a special day for me - not only my birthday, but also the launch of a new sovereign project. 🎉

Last year I released my book “Brick by Brick” about building a sovereign lifestyle.

Today I’m adding another brick: Sovereign Health Intelligence.
For more than a year I’ve been tracking and analyzing my own bloodwork. Existing tools didn’t fit my needs, so I built my own - open source, sovereign by design, self-hostable, with an optional SaaS version.

Can the current system really be fixed from within, or are we trying to repair something that is structurally designed not to be repaired?

In my latest article, I explore the tension between a debt-based monetary system and a Bitcoin-based alternative, drawing on Jeff Booth’s thesis about technology, deflation, and exponential productivity. I also share why my experience as an external consultant reinforces the same conclusion: structural problems rarely solve themselves from inside the structure.

If the incentives are broken, reform is limited. Real change requires a parallel path, built steadily, brick by brick.

Read the full article and let me know where you stand: reform or opt out?

5 Assets Governments Can’t Seize During a Financial Collapse

What really happens to your money when a government runs out of it?
History shows the same pattern again and again. When governments face financial collapse, they don’t disappear. They take what they can reach. Bank accounts are frozen. Savings are converted. Gold is taken. Property is hit with new taxes. Retirement money is redefined.

This has already happened — many times.

Germany in the 1930s. The United States in 1933. Argentina in 2001. Cyprus in 2013. Greece in 2015. Lebanon and Venezuela more recently. Different countries. Same outcome.

So the real question is not “what is illegal for them to take.”
In a crisis, laws change.

The real question is: what is hardest for them to take at all?

In this video, we look at five types of assets that governments struggle to seize, not because of loopholes, but because of how they exist. Some can’t be frozen. Some can’t be tracked. Some can’t be touched.

You’ll learn:
Why money in the bank isn’t fully under your control
How governments take assets without using force
Why skills and knowledge survive every collapse
Why owning something is different from just having access to it
Why location and control matter more than value
Why community and trust matter more than money in hard times

This is not financial advice.
This is a look at history a

Today I responded:

… thank you for reaching out and for explaining the review process.

I have to be honest though - I’m a bit disappointed to see a Bitcoin-only company treating standard on-chain privacy practices as something suspicious. Using privacy tools is, in my view, a legitimate and important part of Bitcoin self-custody, and something every Bitcoin user has the right to do.

That said, to clarify the context:

The Bitcoin sent to my Ledn account is entirely my own Bitcoin stash.

JoinMarket was used purely for privacy reasons, not to obscure ownership or origin.

The purpose of the transfer was simply to add additional collateral / autofill volume to my existing Ledn setup.

I don’t see a reason to justify why I value privacy, but I understand that you are operating within certain compliance constraints.

If this particular UTXO is an issue, I’m happy to offer practical alternatives instead of going through an extensive justification process:

I can withdraw the most recent transaction and resend BTC using different UTXOs, or

If needed, I can withdraw my funds entirely and close the loan.

Please let me know how you would like to proceed, and which option causes the least friction on your side.

A Chinese gold trading platform has just frozen 19 BILLION $ in assets.

Thousands of investors can no longer withdraw their funds.

The platform is offering 20% compensation of the initial capital.

The platform (Jiewurui / JWR in Shenzhen) is facing a classic run/redemption crisis after gold's rally triggered mass withdrawals.

Founded in 2014 as a legitimate gold trader, the company operated physical storefronts and gained trust through competitive pricing and aggressive social media marketing.

But behind the familiar interface of jewelry commerce lurked a betting mechanism. The platform's "pre-pricing" system allowed users to lock in gold or silver prices for future purchase or sale with deposits as small as 20-30 yuan per gram — creating leverage as high as 40-to-1, compared to the Shanghai Gold Exchange's regulated 14% margin requirement.

Planning 2026 With the Sovereign Stack 🧱
A new year is more than a calendar change. It’s a moment to pause and choose direction. For 2026, I’m using the Sovereign Stack as my compass:
Money · Health · Data · Attention · Energy · Mindset · Family · Technology

This framework helped me navigate 2025, think long-term as a new grandfather, and build with intention instead of reacting to noise.
Sovereignty isn’t about extremes.

It’s about responsibility, resilience, and low time preference.

A sovereign life isn’t built in leaps - it’s built brick by brick.

#Sovereignty #Bitcoin #LongTermThinking #Privacy #Resilience #TwentyOneLife

quoting
naddr1qv…jr3v

The beginning of a new year is more than a calendar milestone. It is a symbolic reset, a moment to slow down, breathe in the cold winter air, and reflect on where we stand on our journey toward sovereignty. The snow outside creates a natural stillness that encourages clarity, a perfect environment to plan the year ahead with intention.

For 2026, I am using the full Sovereign Stack (https://twentyone.life/the-five-pillars-of-sovereignty) as my compass. It is the framework that brought stability to 2025, helped me become a grandfather with a clearer sense of responsibility, and guided me through writing Brick by brick. Now it becomes the blueprint for the year ahead.

Below is how I plan 2026 - layer by layer - brick by brick.

1. Money: Stack Sats, Ignore Fiat Noise, Build for the Next Decade

2026 will be a year of disciplined Bitcoin accumulation. My focus is not on the daily volatility or the temporary excitement of fiat price movements. Instead, I am committed to strengthening long-term conviction, dollar-cost averaging consistently, and avoiding emotional decisions. My financial strategy remains simple: stay humble, stack sats, and build a resilient base for future generations, especially now that a grandson is part of my legacy.

2. Health: Training, Recovery, Light, and the Power of Cold

A sovereign life requires a sovereign body. In 2026, I will prioritise the fundamentals: regular strength training, daily walks, and respecting recovery. Morning light exposure, evening red light, and controlled cold exposure will stay part of my routine. These small rituals compound. They make the body more resilient, the mind more clear, and the daily challenges much easier to face.

3. Data: Reduce Digital Footprint, Prepare for a CBDC World

Our digital identity is one of our most fragile assets. In 2026, I will continue reducing my exposure to major platforms, minimising cloud dependencies, and improving my data hygiene. The world is moving towards CBDCs and tighter surveillance. Preparing early, understanding the risks, decentralising your digital life, and building alternatives, is not paranoia. It is responsibility.

4. Attention: Reclaim Focus by Removing Digital Noise

Attention is the most undervalued currency of our time. In 2026, I want to consciously direct it instead of letting algorithms decide for me. I will refine notification hygiene, reduce unnecessary screen time, and strengthen deep work routines. Attention creates output. Attention builds skills. Attention shapes who we become.

5. Energy: Strengthening Personal and Environmental Resilience

Energy is both physical and environmental. Personally, I will invest in building metabolic resilience through movement, nutrition, and breath work. Environmentally, I will continue improving my home infrastructure: efficient heating, backup power options, and reducing waste where possible. When energy is stable, life becomes stable.

6. Mindset: Discipline, Low Time Preference, and Daily Practice

Mindset is not motivation; it is structure. In 2026, I will continue cultivating a low-time-preference mentality, acting for the long term instead of chasing short-term gratification. Meditation, journaling, and deliberately slowing down thinking processes will remain part of my routine. Sovereignty begins internally before it shows up externally.

7. Family: My Grandson as a North Star

Becoming a grandfather changed how I see the future. Legacy is no longer a theoretical concept; it is a real child who will grow up in a world shaped by decisions we make today. In 2026, I want to be more present, more intentional, and more supportive. My Sovereign Stack is not only for me, it is a structure I want to pass on to the next generation. My previous article on this topic: https://www.linkedin.com/pulse/how-do-we-raise-children-non-fiat-values-fiat-world-schindlwick-gufwf/

8. Technology & Privacy: Building a Private and Resilient Tech Stack

Technology should empower, not control. My 2026 technical roadmap includes strengthening my self-hosted infrastructure, expanding Tor usage, improving my Bitcoin node setup, and adopting more decentralised tools. The world is shifting fast, and privacy is becoming a luxury. Building your own digital fortress is no longer optional, it is essential.

Closing Reflection

A sovereign life is not built in dramatic leaps. It is constructed through small, intentional choices. It is the daily discipline of doing the right thing, even when nobody is watching. It is the courage to build a life rooted in freedom, responsibility, and long-term thinking.

Sovereignty is built brick by brick, day by day.

Becoming a Grandfather Changed Everything for Me.

A few weeks ago, I became a grandfather. Little Oskar is now a bit over one month old, but he already changed the way I look at the world. I kept thinking about the future he will grow into. A world shaped by technology, money systems, incentives, and social structures that even adults often struggle to understand.

And that led me to a simple but powerful question:

How can I teach my grandson the core values behind Bitcoin - things like decentralisation, scarcity, honesty, responsibility, and sovereignty, without overwhelming him with technical words?

These are concepts where even grown-ups stumble. So how could a child learn them in a way that feels natural, simple, joyful, and maybe even magical?

That’s when a new idea was born.

Introducing a New Book Series Concept

“Little Satoshi’s Big Lessons - 21 Stories for a Sovereign Life”

After publishing my book “Brick By Brick” (https://amzn.to/4mW2pK4) , something unexpected happened. I realised there is a quiet but important gap in the Bitcoin space, one that becomes especially visible when you start thinking about the values you want to pass on to the next generation. Adults can take courses, watch videos, read articles, join discussions. But what about children? How do we help them understand the deeper values behind Bitcoin, not the technology, not the charts, not the vocabulary, but the human principles at the core of it?

I often asked myself: How can a child learn what decentralisation feels like? How can they appreciate scarcity? How can they understand fairness, honesty, responsibility, and the idea that their choices matter, long before they learn words like “permissionless” or “consensus”?

Bitcoin is built on powerful moral foundations, yet those foundations can be taught long before the child ever hears the word “Bitcoin.”

That thought became the seed for a new project. I began designing a 21-part children’s book series, intentionally mirroring the 21 million Bitcoin. Each part represents one core value, one life principle, one “satoshi nut” of wisdom that can help children grow into curious, resilient, sovereign human beings. And instead of long explanations or abstract concepts, the series uses stories, simple, playful, relatable stories that meet the child where they are.

Satoshi the Squirrel - First concept of this character

To guide them through these lessons, I created a character children can immediately connect with: Satoshi the Squirrel. He is wise but funny, curious but grounded, and always learning, just like the young reader. Satoshi collects little “satoshi nuts,” each nut representing a piece of understanding he gains through his adventures. Over the course of the 21 book parts, he slowly builds his own decentralised stack of wisdom. Children follow him, learn with him, and celebrate each nut he earns. Maybe at the end of the book a quick quiz, with some real satoshis to earn, similar to "21 Days of Bitcoin" (https://bitcoinmagazine.com/sponsored/learn-bitcoin-earn-bitcoin-announcing-unchained-as-title-sponsor-for-21-days-of-bitcoin-educational-course)? Let me know if you have any ideas to incentivise the learning.

Each book parts in the series focuses on one universal value: fairness, transparency, effort, patience, scarcity, responsibility, cooperation, independence, critical thinking, digital safety, and many more. Twenty-one values in total, one for every “million” Bitcoin, forming a complete journey from childhood to young adulthood.

There is no Bitcoin vocabulary in the pages. No charts. No crypto terminology. Just human values, the values that make Bitcoin what it is.

Because Bitcoin is not only technology. Bitcoin is a philosophy. Bitcoin is character. Bitcoin is how you behave when no one is watching. These concepts i built my book "Brick By Brick" and my TwentyOne.Life Manifesto on.

And children can learn those values long before they understand the technology behind them. This project is my attempt to bring that philosophy into a form a child can truly understand and enjoy, starting with my newborn grandson Oskar.

If we can teach children these values early, the understanding of Bitcoin will come naturally later.

Why I Believe This Matters

We are living in a time where trust in systems is steadily declining, where attention spans are becoming shorter with every new distraction, and where money itself is turning into something increasingly abstract and difficult to grasp, even for adults. Our children grow up in a world filled with digital risks that are often invisible to them, and a culture shaped by instant gratification, where nearly everything can be accessed immediately with a swipe or a tap.

Against this backdrop, teaching children the foundations of sovereignty, resilience, patience, and long-term thinking becomes not just helpful, but essential. These qualities prepare them for a future in which independence and critical thinking will matter more than ever.

I genuinely believe that Bitcoiners, with our strong focus on values like responsibility, honesty, transparency, and decentralisation, can offer something meaningful to the next generation. But the way to do that is not through preaching or pushing technical explanations onto children. Instead, we can pass on these ideas through storytelling.

Stories have a unique ability to shape values. Values guide behaviour. And behaviour ultimately shapes the future. If we want our children and grandchildren to grow into sovereign, thoughtful adults, the journey begins not with technology, but with the stories we tell them today.

How These 21 Parts Orange-Pill Kids (Without Ever Saying “Bitcoin”)

One of the most exciting discoveries during the development of this project was realising how naturally Bitcoin’s core principles translate into universal childhood lessons. When you remove the technical language and look at the values underneath, you find timeless teachings about fairness, responsibility, effort, honesty, patience, and curiosity, concepts children encounter every single day.

This is where the magic happens: children can internalise the essence of Bitcoin long before they ever need to understand the technology behind it. Through stories, metaphors, and the gentle guidance of Satoshi the Squirrel, they learn the mindset that makes sovereignty possible.

Here is how these 21 parts quietly and playfully align Bitcoin’s principles with everyday childhood lessons:

Translation Bitcoin Principles vs. Children Lessons

I know, the translations are not perfect and will need further be developed.

Transforming Complex Ideas Into Lifelong Values

When taught through stories, these lessons become part of a child’s emotional and moral foundation, not just intellectual knowledge. Long before they study money, technology, or digital systems, they already feel what fairness means, understand why effort matters, recognise the importance of privacy, and appreciate why some things become special when they are scarce.

By the time they are teenagers or young adults, Bitcoin will make sense to them not because someone explained it, but because they already live by its principles.

This is the heart of the project: planting values today that grow into sovereignty tomorrow.

Do You See a Need or a Market for This?

This is where I need your feedback. Would parents, grandparents, educators, Bitcoiners, and curious families appreciate:

Is there a gap in the market for this kind of educational storytelling?

I would love to hear your thoughts, ideas, questions, and critiques.

For me, this is no longer just a book project. It’s a way to share something meaningful with my grandson, and with all the young “stackers” growing up in a world that desperately needs better values.

Winter is here - and with it comes the perfect moment to slow down, breathe, and return to Bitcoin’s true intrinsic values.

Not the price. Not the hype.

But sovereignty, self-custody, decentralisation, and long-term responsibility.

This year, becoming a grandfather and publishing my book reminded me why stacking sats in winter is more than a strategy, it’s a mindset grounded in clarity and intention.

What does winter teach you about Bitcoin and sovereignty?

Winter Is the Best Time to Stay Humble and Stack Sats

Winter has a natural way of slowing life down. The cold air, the shortened days, and the quiet evenings invite us to pause and reflect. Yet this year, instead of silence, many people feel tension. Markets are falling, sentiment is declining, and both Bitcoin and traditional equities are showing red candles. But perhaps the contrast between winter’s stillness and the world’s nervousness is exactly what we need. When the external noise grows louder, the importance of strengthening our internal compass becomes clearer.

Winter strips away distraction. And when the layers of speculation, price obsession, and financial noise fall away, what remains is the intrinsic value of Bitcoin, the part of Bitcoin that no market cycle can touch. These intrinsic values form the foundation of sovereignty, responsibility, and long-term thinking. They become especially visible when the world cools down, because winter invites us to return to what truly matters.

Why Winter Is the Perfect Environment to Reconnect With Bitcoin’s Intrinsic Values

1. Sovereignty - Control Over Your Own Future

Bitcoin gives individuals control over their money in a world where financial autonomy is gradually being absorbed by institutions. But this autonomy only becomes real when it is held directly, without intermediaries. True sovereignty begins the moment you take responsibility for holding your own keys.

No ETF, no exchange, and no third-party custodian can give you the sovereignty that Bitcoin was created to deliver. ETFs operate with their own business rules, custodial accounts can be frozen, and exchanges can be hacked, regulated, or shut down. When you rely on a custodian, you do not own Bitcoin, you own a promise.

Only self-custody, holding your own private keys, preserves Bitcoin’s core property: That no one can seize, censor, inflate, or manipulate your money. Self-custody turns Bitcoin from a speculative asset into a sovereign tool. It transforms passive ownership into active responsibility. And in the silence of winter, when the instability of the traditional financial system becomes visible, the value of having something truly self-sovereign becomes undeniable. Winter reminds us that sovereignty is not something granted, it is something earned and maintained through discipline and awareness.

2. Predictability in a Fiat World of Uncertainty

One of Bitcoin’s greatest intrinsic strengths is its absolute predictability. Fiat currencies move in response to political agendas, central bank meetings, inflation targets, and short-term economic pressures. The rules change depending on who is in power or what crisis emerges next.

Bitcoin, by contrast, continues steadily, unchanged, unaffected, uninterested in political cycles or emotional markets. Every ten minutes another block is produced, exactly as designed. Every halving reduces issuance, exactly on schedule. The total supply will never exceed 21 million, no matter what happens in the world. This predictability is not merely technical, it is psychological. It allows individuals to think in decades. It allows savers to plan without fear of silent theft through inflation. It allows families to build wealth on a foundation that cannot be altered by a signature or a press conference.

In winter, when uncertainty feels heavier and the global economy appears fragile, Bitcoin’s predictable nature becomes a source of calm, stability, and clarity.

3. Decentralisation - A System Without a Single Point of Failure

Decentralisation is one of the most misunderstood yet essential intrinsic values of Bitcoin. It means that the network is not controlled by any single authority, not a government, not a corporation, not a central bank, and not even its creator. Its strength comes from many independent participants collectively enforcing the same rules.

Bitcoin’s decentralisation ensures that the rules cannot be changed impulsively, that no one can shut down the network globally, and that every participant, whether a small home miner or a large institution, operates under the exact same protocol. It removes the need for trust in any institution and replaces it with cryptographic truth, consensus, and transparency.

But decentralisation is not perfect, and Bitcoin is honest about that.

There are real challenges:

Mining tends to concentrate in large industrial facilities.

Hashrate is often aggregated through a handful of mining pools.

ASIC manufacturing is dominated by a small number of chip makers.

Supply chains for mining hardware are not yet globally diversified.

These are genuine points of vulnerability, and acknowledging them is part of understanding Bitcoin’s long-term evolution. The important lesson is this: Bitcoin is decentralised enough to resist capture today, and decentralisation continues improving over time.

New mining pool protocols reduce trust in operators, more countries participate in mining, ASIC production is slowly expanding, and open-source hardware communities are designing the next generation of tools. The broader ecosystem, “team Bitcoin,” from developers to miners to node runners, is constantly working to reduce centralisation pressure and strengthen the resilience of the network.

In winter, when global systems feel more fragile and geopolitical tensions rise, decentralisation becomes more than a technical feature, it becomes peace of mind. It is the reassurance that no single failure can destroy the system you rely on, and that a global community is actively working to keep Bitcoin free, open, and resilient.

Decentralisation is not a static achievement. It is a living defence, one that grows stronger every year.

4. Low-Time-Preference Mindset - A Philosophy of Patience and Responsibility

Bitcoin naturally encourages long-term thinking. It rewards patience, discipline, and self-restraint, qualities that feel increasingly rare in a world driven by instant gratification.

A low-time-preference mindset means investing in the future instead of reacting to the present. It means valuing stability over speculation, intention over impulse, and responsibility over convenience.

Bitcoin helps cultivate this mindset because its design nudges people to zoom out, to observe patterns over years instead of days, and to build systems, habits, and goals that compound over time.

Winter reinforces this mindset. It is the season of preparation, reflection, and careful planning. It invites us to slow down, to think deeply, and to align our actions with long-term values rather than short-term emotions.

5. A Savings Technology That Protects Generations

Beyond its monetary properties, Bitcoin is a tool for intergenerational stability. Where fiat savings lose value over time, Bitcoin preserves it. Where traditional systems erode purchasing power, Bitcoin strengthens it through scarcity and predictable issuance.

This perspective became deeply personal for me this year. Releasing my book was an act of documenting lessons for my future self and for others on their sovereign journey. Becoming a grandfather reshaped the concept of long-term planning. It reminded me that the decisions we make today, the habits we build, the values we uphold, the systems we trust, have consequences far beyond our own lifetime.

Bitcoin is not just money for us. It is money for the people who will follow us. It is a foundation we can hand down that cannot be stolen by inflation, manipulated by politicians, or destroyed by economic instability.

“Price is the distraction. Principles are the compass.”

Every winter, this message becomes even clearer. Price fluctuates with human emotion. Principles remain anchored in truth.

Your 3-Point Winter Stacking Checklist

1. Automate your stacking

Remove emotion from your decisions and let consistency build your sovereignty over time.

2. Revisit your sovereignty plan

Define what freedom means across money, data, health, attention, and energy. Bitcoin is one pillar, your life has many.

3. Reduce noise, increase signal

Unfollow sources that amplify fear or hype and replace them with books, timeless thinkers, and practices that reinforce clarity.

If you want to explore these intrinsic values further…

My book Brick by Brick dives into sovereignty, low-time-preference living, and the philosophical foundations of Bitcoin. It is written for the thinkers, the builders, the quiet operators, and everyone who seeks a more sovereign path in a world moving toward centralisation.

Summary

Winter is not just a season, it is an invitation to slow down, observe more clearly, and reconnect with first principles. When markets are down and sentiment is low, the true strength of Bitcoin becomes visible: its predictable monetary policy, its decentralised structure, its sovereignty, and its ability to anchor long-term thinking. This winter, I invite you to focus not on the price but on the principles that make Bitcoin valuable in every season. Stack with intention, plan with patience, and build a future that stands on solid ground.

Rindsloullade – a true Austrian classic 🇦🇹🥩

If you ever visit Austria, Rindsloullade is one of those dishes you absolutely need to try. It’s thinly sliced beef, rolled up and filled with mustard, onions, bacon and pickles, then slowly braised until it becomes incredibly tender.

The magic is in the long cooking time: the beef absorbs all the flavors and transforms into a rich, comforting meal. Traditionally served with potato dumplings or simple buttered noodles, it’s pure homestyle cooking that tastes like a warm alpine hug.

A simple dish, but full of character, just like Austria itself. 🇦🇹💛

Let me know in the comment how this is called in our country.

2025-11-18T11:15:49Z

Becoming a grandfather changed everything for me. Holding little Oskar for the first time made me rethink the future we’re handing to the next generation - a future shaped by money, technology, incentives, and values.

That’s why I started a new project: “Little Satoshi’s Big Lessons - 21 Stories for a Sovereign Life". A children's book series that teaches the core values behind Bitcoin - without ever mentioning Bitcoin.

Fairness. Responsibility. Scarcity. Honesty. Sovereignty. Simple, playful, meaningful stories for kids, inspired by the lessons we wish we learned earlier.
I’d love your feedback.

Do you think the world needs a project like this?

Becoming a Grandfather Changed Everything for Me.

A few weeks ago, I became a grandfather. Little Oskar is now a bit over one month old, but he already changed the way I look at the world. I kept thinking about the future he will grow into. A world shaped by technology, money systems, incentives, and social structures that even adults often struggle to understand.

And that led me to a simple but powerful question:

How can I teach my grandson the core values behind Bitcoin - things like decentralisation, scarcity, honesty, responsibility, and sovereignty, without overwhelming him with technical words?

These are concepts where even grown-ups stumble. So how could a child learn them in a way that feels natural, simple, joyful, and maybe even magical?

That’s when a new idea was born.

Introducing a New Book Series Concept

“Little Satoshi’s Big Lessons - 21 Stories for a Sovereign Life”

After publishing my book “Brick By Brick” (https://amzn.to/4mW2pK4) , something unexpected happened. I realised there is a quiet but important gap in the Bitcoin space, one that becomes especially visible when you start thinking about the values you want to pass on to the next generation. Adults can take courses, watch videos, read articles, join discussions. But what about children? How do we help them understand the deeper values behind Bitcoin, not the technology, not the charts, not the vocabulary, but the human principles at the core of it?

I often asked myself: How can a child learn what decentralisation feels like? How can they appreciate scarcity? How can they understand fairness, honesty, responsibility, and the idea that their choices matter, long before they learn words like “permissionless” or “consensus”?

Bitcoin is built on powerful moral foundations, yet those foundations can be taught long before the child ever hears the word “Bitcoin.”

That thought became the seed for a new project. I began designing a 21-part children’s book series, intentionally mirroring the 21 million Bitcoin. Each part represents one core value, one life principle, one “satoshi nut” of wisdom that can help children grow into curious, resilient, sovereign human beings. And instead of long explanations or abstract concepts, the series uses stories, simple, playful, relatable stories that meet the child where they are.

Satoshi the Squirrel - First concept of this character

To guide them through these lessons, I created a character children can immediately connect with: Satoshi the Squirrel. He is wise but funny, curious but grounded, and always learning, just like the young reader. Satoshi collects little “satoshi nuts,” each nut representing a piece of understanding he gains through his adventures. Over the course of the 21 book parts, he slowly builds his own decentralised stack of wisdom. Children follow him, learn with him, and celebrate each nut he earns. Maybe at the end of the book a quick quiz, with some real satoshis to earn, similar to "21 Days of Bitcoin" (https://bitcoinmagazine.com/sponsored/learn-bitcoin-earn-bitcoin-announcing-unchained-as-title-sponsor-for-21-days-of-bitcoin-educational-course)? Let me know if you have any ideas to incentivise the learning.

Each book parts in the series focuses on one universal value: fairness, transparency, effort, patience, scarcity, responsibility, cooperation, independence, critical thinking, digital safety, and many more. Twenty-one values in total, one for every “million” Bitcoin, forming a complete journey from childhood to young adulthood.

There is no Bitcoin vocabulary in the pages. No charts. No crypto terminology. Just human values, the values that make Bitcoin what it is.

Because Bitcoin is not only technology. Bitcoin is a philosophy. Bitcoin is character. Bitcoin is how you behave when no one is watching. These concepts i built my book "Brick By Brick" and my TwentyOne.Life Manifesto on.

And children can learn those values long before they understand the technology behind them. This project is my attempt to bring that philosophy into a form a child can truly understand and enjoy, starting with my newborn grandson Oskar.

If we can teach children these values early, the understanding of Bitcoin will come naturally later.

Why I Believe This Matters

We are living in a time where trust in systems is steadily declining, where attention spans are becoming shorter with every new distraction, and where money itself is turning into something increasingly abstract and difficult to grasp, even for adults. Our children grow up in a world filled with digital risks that are often invisible to them, and a culture shaped by instant gratification, where nearly everything can be accessed immediately with a swipe or a tap.

Against this backdrop, teaching children the foundations of sovereignty, resilience, patience, and long-term thinking becomes not just helpful, but essential. These qualities prepare them for a future in which independence and critical thinking will matter more than ever.

I genuinely believe that Bitcoiners, with our strong focus on values like responsibility, honesty, transparency, and decentralisation, can offer something meaningful to the next generation. But the way to do that is not through preaching or pushing technical explanations onto children. Instead, we can pass on these ideas through storytelling.

Stories have a unique ability to shape values. Values guide behaviour. And behaviour ultimately shapes the future. If we want our children and grandchildren to grow into sovereign, thoughtful adults, the journey begins not with technology, but with the stories we tell them today.

How These 21 Parts Orange-Pill Kids (Without Ever Saying “Bitcoin”)

One of the most exciting discoveries during the development of this project was realising how naturally Bitcoin’s core principles translate into universal childhood lessons. When you remove the technical language and look at the values underneath, you find timeless teachings about fairness, responsibility, effort, honesty, patience, and curiosity, concepts children encounter every single day.

This is where the magic happens: children can internalise the essence of Bitcoin long before they ever need to understand the technology behind it. Through stories, metaphors, and the gentle guidance of Satoshi the Squirrel, they learn the mindset that makes sovereignty possible.

Here is how these 21 parts quietly and playfully align Bitcoin’s principles with everyday childhood lessons:

Translation Bitcoin Principles vs. Children Lessons

I know, the translations are not perfect and will need further be developed.

Transforming Complex Ideas Into Lifelong Values

When taught through stories, these lessons become part of a child’s emotional and moral foundation, not just intellectual knowledge. Long before they study money, technology, or digital systems, they already feel what fairness means, understand why effort matters, recognise the importance of privacy, and appreciate why some things become special when they are scarce.

By the time they are teenagers or young adults, Bitcoin will make sense to them not because someone explained it, but because they already live by its principles.

This is the heart of the project: planting values today that grow into sovereignty tomorrow.

In reply to nevent1q…rax0
_________________________

You’re correct that Core v30 didn’t change the OP_RETURN limit itself, only the default relay policy. However, as a node operator, I’m free to enforce stricter policies locally, and I intend to.

I don’t want to relay or store larger OP_RETURN transactions because:
1. Legal risk: Hosting or relaying arbitrary on-chain data (especially CASM content) is illegal under EU law when it includes copyrighted or illicit material. As a node operator in the EU, I have a legal obligation to minimize exposure to such data.
2. Network efficiency: Larger OP_RETURN payloads bloat the UTXO set and mempool bandwidth without contributing to Bitcoin’s core purpose, financial settlement.
3. Principle of minimalism: Bitcoin’s design goal is censorship resistance for money, not a general-purpose data storage system. Keeping relay policies tight preserves the network’s scalability and neutrality.

So while Bitcoin Core’s position is about maintaining realistic relay behavior, my stance as an operator is simple: my node, my policy. I will not relay or store CASM or any non-financial payloads. Don’t care if it’s Core or Ocean propaganda, try to apply common sense.

Introduction: A New Controversy in Bitcoin’s Evolution

If you hold Bitcoin, if you call yourself a Bitcoiner, are you prepared to accept that the Bitcoin blockchain could be used to store illicit, even illegal content? This isn’t a hypothetical. Unless we act, by October 2025 the default Bitcoin Core software will make this the new reality. And if you don’t react now, your silence means acceptance.

Bitcoin is facing a pivotal controversy that cuts to the heart of its identity. The debate centres on a proposed change in Bitcoin’s core software that would remove longstanding limits on storing arbitrary data in transactions. On the surface, this change sounds technical – raising the OP_RETURN data limit from 80 bytes to nearly 4 megabytes, but its implications are profoundly human. Supporters hail it as an overdue embrace of censorship-resistance, while critics warn it could turn the blockchain into a host for illegal or abusive content. As a Bitcoiner who champions self-sovereignty and Bitcoin’s reputation as sound money, I find myself firmly in the latter camp. This article, written from my personal perspective and drawing on my book’s focus (Brick by Brick - <https://twentyone.life/brick-by-brick>) on self-sovereignty, explores why I’m taking a stand by running alternative software and even boycotting certain services, all in the name of a “clean” future for Bitcoin.

Background: Bitcoin Core v30 and the OP_RETURN Debate

At issue is a change slated for the upcoming Bitcoin Core version 30 (expected October 2025). Bitcoin Core is the dominant software for running nodes (over 75% of nodes run so its defaults largely define network behaviour. The core developers have decided to unshackle the OP_RETURN field, which historically allowed embedding only a tiny piece of data (≤83 bytes) in a transaction. This limit acted as a de facto “spam filter”, discouraging users from turning Bitcoin’s ledger into a generic data storage system.

Under Core v30, that filter is being removed entirely: users will be able to attach much larger data payloads, up to the size of a full block (~4MB), in a single transaction output. Moreover, Bitcoin Core will eliminate the configuration options (data carrier settings) that previously let node operators refuse relaying big OP_RETURN transactions. In short, the new default policy is “anything goes” for data, and individual node runners won’t easily opt out. While v30 still offers command-line tweaks to impose custom limits, those are now deprecated warnings likely to be removed later.

Why make this change? Proponents argue it’s a pragmatic response to reality. The 80-byte cap, they say, has been routinely bypassed by creative users who already insert larger data through other means – for example, using Taproot witness data or fake outputs (as seen in the 2023 Ordinals/“inscriptions” craze that let people embed images and art on Bitcoin). These workarounds are actually worse for the network: since the data is hidden in spendable outputs or witness scripts, it can bloat the UTXO set (the list of unspent coins) and increase validation costs for all nodes. By contrast, OP_RETURN outputs are provably unspendable and easily prunable. In the eyes of Core developers, it’s better to let people put data in OP_RETURN (where it doesn’t harm UTXO or decentralisation) than to have them continue abusing more harmful trick. Removing the cap “yields at least two tangible benefits: a cleaner UTXO set and more consistent default behaviour,” explained developer Greg Sanders. The change also aligns with Bitcoin’s values of neutrality, if a transaction is valid and pays the fee, who are nodes to censor it? Core maintainers like Gloria Zhao argue that trying to filter transactions at the node level is futile and against the principle of censorship-resistance.

On the other side, critics are alarmed. They counter that dropping these limits will open the floodgates to arbitrary data, fundamentally altering Bitcoin’s purpose. The blockchain could become a bloated “immutable database” of random content, potentially crowding out financial transactions with higher fees and diluting Bitcoin’s use as peer-to-peer money. What’s more, unbounded data storage invites spam, people could stuff blocks with endless memes, ads, or junk simply because they’re willing to pay. It’s a replay of the Blocksize War arguments, but instead of bigger blocks for payments, it’s bigger payloads for non-monetary data. The community is starkly divided: should Bitcoin evolve to support broader use cases (data, NFTs, digital artifacts), or should it resist becoming a free-for-all content repository and stick to financial utility? These positions are diametrically opposed, and the conflict has been heated – drawing comparisons to the acrimony of the 2017 blocksize debates.

Notably, longtime Bitcoin developer Luke Dashjr (author of an alternative client called Bitcoin Knots - https://x.com/LukeDashjr) has been one of the most vocal opponents besides Bitcoin Mechanic and Bitcoin University ( primal.net/kratter). He warns that the removal of what he bluntly calls “spam filters” is potentially harmful to the network and its users. Dashjr has publicly urged node operators to avoid upgrading to Core v30 or to switch to alternative software like Bitcoin Knots. In fact, many Bitcoiners have already acted on that advice. When the OP_RETURN plan was announced and fast-tracked earlier this year, there was a surge of users migrating their nodes from Core to Knots, by some estimates, over 15% of previously Core nodes switched to Bitcoin Knots in protest. The stage is set for a grass-roots pushback using Bitcoin’s own strength: decentralisation. True to the mantra of self-sovereignty, if you disagree with the default rules, you are free to run a node that reflects your values. I count myself among those taking that step.

Illicit Content on the Blockchain: The Serious Risks

Why am I, and others, so concerned about lifting the data limits? Because it’s not just “cute cat pictures” or art collections that could find their way onto Bitcoin’s ledger. The most dire possibility is the inclusion of illicit and abusive content in an immutable, globally replicated chain. This isn’t idle paranoia; it’s a genuine risk recognised by both sides of the debate. Even the advocates of OP_RETURN freedom acknowledge the “undesirable second-order effects” that could follow. Let’s spell it out: What if someone starts embedding child sexual abuse material (CSAM) or other illegal data in Bitcoin transactions? Once mined into a block, that content is there forever, every full node would unknowingly host it on their hard drive as part of the blockchain spreaded on tens of thousands nodes across the world. This scenario is a nightmare for obvious moral reasons, and it also poses a legal and reputational threat to anyone running a node or the Bitcoin network as a whole. Besides this, to spin up a new node will take longer and need higher technical hardware which leads to centralisation.

Unfortunately, the threat is not theoretical. It has already happened on a small scale. Researchers have found that forbidden content made its way onto Bitcoin as early as 2013, albeit in an obscure form. In 2018, a paper famously claimed that Bitcoin’s blockchain contained links to child pornography; at the time, critics dismissed it as sensationalism since only a few bytes of encoded data were involved and Core’s filters limited further abuse. But today we’re looking at a very different landscape. The data per block is increasing dramatically with the new policy. A concerned Bitcoiner known as “Bitcoin Mechanic” ( primal.net/p/nprofile1qqs8fl79rnpsz5x00xmvkvtd8g2u7ve2k2dr3lkfadyy4v24r4k3s4sh8dmel) recently warned that removing the filter “will draw unforeseen consequences,” meaning content like child pornography can appear on the Bitcoin blockchain” once v30 goes live. His point is straightforward: if you give bad actors the ability to inject large payloads, someone will inevitably push the worst kind of content into the system. And perversely, there’s a twisted incentive for them to do so: “Getting other people to store it for you is vastly preferable to storing it yourself,” Mechanic notes, what better way for criminals to disseminate vile material than piggyback on tens of thousands of innocent Bitcoin nodes?

Core developers have responded that these fears may be overblown. They often cite examples of other blockchains (for instance, Monero or Ethereum) that don’t have such data limits yet haven’t become overrun with illegal content. They stress that Bitcoin’s permissionless nature means anything could be written to it, but that doesn’t mean an epidemic of criminal data is imminent. Perhaps, but I would counter that Bitcoin’s global prominence and immutable design make it a uniquely attractive target for someone trying to cause chaos or discredit the system. It only takes one high-profile incident of truly heinous content on Bitcoin to unleash a regulatory crackdown. Remember, Bitcoin’s censorship-resistance cuts both ways: it empowers individuals, but it also neutralises traditional controls, which is exactly why governments get antsy when crimes enter the mix.

The legal implications of this are untested and scary. If a Bitcoin block contains illegal pornography or violent propaganda, could authorities argue that every node operator is technically in possession of contraband data? Some in the community worry that, yes, this could give governments a “perfect excuse to outlaw Bitcoin or make running a node illegal”. Even if that outcome is unlikely in jurisdictions that understand how Bitcoin works, the mere perception that Bitcoin is hosting criminal content would be a PR disaster. It would hand ammunition to anti-crypto politicians and could make regulators slam the brakes on adoption. As a Bitcoiner who wants to see this technology thrive, I find that risk unacceptable. Bitcoin’s social contract might be robust against internal dissent, but it’s not immune to external legal attack. Preserving Bitcoin’s integrity means ensuring it doesn’t become synonymous with “dark web file storage” in the public eye.

Embracing Self-Sovereignty: Why I Run Bitcoin Knots

My response to this situation has been guided by one of Bitcoin’s core principles: self-sovereignty. In essence, self-sovereignty means taking full ownership of your participation in the network, holding your own keys, and running your own node with the rules you choose. In the book I authored on Bitcoin and self-sovereign principles, I emphasised that running a node is more than a technical task; it’s an expression of personal agency and values. Now, faced with Bitcoin Core’s direction that I deeply disagree with, I’m putting that ethos into practice.

For the past four months, I have been running Bitcoin Knots instead of the standard Bitcoin Core software. Bitcoin Knots is a well-established alternative client (maintained by Luke Dashjr) that, in many ways, is identical to Core except for a few important differences, notably, Knots retains stricter limits on OP_RETURN data and gives the user full control over relay filters. In fact, Knots by default still caps OP_RETURN at 40 bytes (the old limit from years ago) and allows only one OP_RETURN output per transaction. It’s basically “Bitcoin Core, but with the spam filter intact.” By running Knots, my node will not relay or mine the kind of oversized data-storing transactions that Core v30 endorses. More importantly, it signals my support for a vision of Bitcoin that prioritises financial transactions over arbitrary data. Knots users (myself included) see ourselves as defending Bitcoin’s integrity from a controversial experiment. We are effectively saying, “Not on my node!” when it comes to turning Bitcoin into an uncensored data dump.

I’m far from alone in this choice. As mentioned, a substantial minority of node operators are switching to Knots or sticking with older Core versions. This grass roots movement is reminiscent of how users can enforce their preferences in Bitcoin – much like the User Activated Soft Fork (UASF) concept, node runners can ‘vote’ by choosing which software to run. If enough of us reject Core v30, it could create economic incentives for miners to think twice about stuffing blocks with junk that a portion of the network won’t relay or perhaps even accept. (To be clear, Knots today does accept blocks created under Core’s new rules – it’s not a hard fork. The divergence is in relay policy and default behaviour, not consensus rules. This is a fight being waged via network policy, not chain splits… at least not yet.)

Self-sovereignty also means accepting personal responsibility for what I support in the network. That extends beyond just the software I run. It also influences my choices as a customer and community member. In light of the OP_RETURN controversy, I have decided on a few concrete actions, which I’ll outline here:

Running a “clean” node: I’ve migrated all my nodes to Bitcoin Knots and will continue to do so for the foreseeable future. This ensures that I am not propagating or validating illicit data beyond the absolute minimum required by consensus. If a bloated transaction or block crosses my node, Knots’ policies will treat it with the maximum strictness allowed (dropping it from mempool if possible, and certainly not relaying such transactions to peers). This is my way of keeping my corner of the Bitcoin network as clean of illicit content as possible. It’s a personal stand: I do not want even the chance of illegal material passing through my machine.

Boycotting services that endorse Core v30: I am discontinuing my use of any exchanges, custodians, or Bitcoin companies that I know are upgrading to or support the Core v30 software without protest. For example, if a company like River Financial or a tech firm like Blockstream chooses to run Core v30 nodes (thus knowingly accepting the relay of unlimited content, illicit or otherwise), then I will not be doing business with them. Those organizations might trust their lawyers or regulators to sort out the fallout of hosting illicit data on their nodes – that’s their prerogative. But I cannot in good conscience support institutions that, in my view, are inviting a flood of abusive content onto the Bitcoin blockchain and risking its reputation. My money and support will go to those who keep Bitcoin robust and respectable.

Advocating for a “clean” Bitcoin (even if it means a fork): Looking ahead, I suspect that other major players in the Bitcoin ecosystem share my concern, even if they aren’t voicing it loudly yet. Think of large public companies holding Bitcoin in their treasuries, or firms planning Bitcoin ETFs. The last thing these institutions want is to be entangled with a network that could inadvertently facilitate the spread of illegal content. It’s not hard to imagine some of them drawing a line: if Bitcoin’s protocol won’t address this problem, they might resort to extraordinary measures. This could include supporting a hard fork to create a “clean” version of Bitcoin that excises or filters out illicit material. BlackRock, for instance, is on the cusp of launching a spot Bitcoin ETF. In BlackRock’s own filings, they note that in the event of a fork, they have full discretion to decide which chain to consider the “real” Bitcoin for their fund.That means if a new fork gained momentum – say, a Bitcoin variant with strict protocol rules against arbitrary data – BlackRock could opt to adopt it for their ETF (or conversely, to abandon a chain that becomes too toxic). While this scenario sounds extreme, it’s entirely within the realm of possibility. The very fact that we’re discussing child pornography on the blockchain may prompt powerful stakeholders to assert control to protect their investments. I’m not actively calling for an immediate fork, that’s a complex, last-resort path, but I do believe that if Bitcoin Core’s path leads to legal quagmires, the market will find a way to course-correct, even if it means a chain split. My hope is that by raising awareness now, we can avert such drastic outcomes. But make no mistake: Bitcoin’s future must not include being a playground for criminal content, and I’ll support any serious effort to ensure that.

Bitcoin’s Future: Balancing Freedom and Responsibility

The controversy over OP_RETURN and illicit content forces an uncomfortable but necessary conversation about the future we want for Bitcoin. On one side is the ideal of total neutrality, Bitcoin as an unfilterable, permissionless ledger where “code is law” and even questionable data is just data. On the other side is the recognition that Bitcoin does not exist in a vacuum: if we undermine its primary use case as money or subject its participants to legal peril, we could kill the proverbial goose that lays the golden eggs. Finding the right balance is tricky. We cherish Bitcoin’s censorship-resistance precisely because it protects financial freedom and speech. Yet, does rejecting any filtering, even of grotesquely abusive content, truly serve the cause of freedom? Or does it hand enemies of Bitcoin the very weapon they need to attack it? These are challenging questions, and reasonable people in the community answer them differently.

For me, the answer comes back to self-sovereignty and consent. I did not sign up to store illicit images or arbitrary gigabytes of data on my node, that’s not the social contract under which I joined Bitcoin. My consent as a node operator matters. True decentralisation means we, the users get to collectively decide what the blockchain is for, by either running or not running certain code. It’s heartening to see that even Core developers acknowledge this in principle: “If Bitcoin Core’s contributors ever abandon [Bitcoin’s core] values… the community will switch to another node implementation that does it better,” wrote Gloria Zhao amidst the debate. I’d argue that forcing nodes to relay and store unlimited junk (with potentially ghastly contents) is a departure from the values that brought many of us to Bitcoin. And indeed, we’re seeing the community vote with its feet, or rather with its node software.

Moving forward, I believe Bitcoin will be stress-tested on this front. The coming months and years will reveal whether the network can accommodate new use-cases (like data inscriptions) without losing its soul – or whether a correction is needed. Perhaps Bitcoin Core’s gambit will pay off: maybe the “spam” will remain manageable, new pruning techniques will mitigate the bloat, and no criminal will attempt to abuse the blockchain’s openness. In that best case, my concerns would be eased (and I’d gladly acknowledge an overabundance of caution on my part). But if the worst case materialises, if obscene data starts showing up in blocks, if typical users find the chain clogged with non-financial data, if governments use this as a cudgel – then the community must be ready to respond decisively. Hard forks have happened before in Bitcoin’s history when values were at stake (recall the split that created Bitcoin Cash in 2017 over a blocksize dispute). A fork to preserve Bitcoin’s legal cleanliness and focused mission might become not just acceptable but essential to “future-proof” the network. And unlike a protocol tweak coming from a small group, a community or institution-driven fork would reflect a broad consensus that Bitcoin as it was is worth defending. BlackRock and other institutional players entering the space could ironically become allies in keeping Bitcoin safe for mainstream use – they will not tolerate holding an asset tainted by crime, so they have every incentive to back a solution, even if it’s a controversial one.

Conclusion: Upholding Bitcoin’s Integrity

In closing, my stance can be distilled to this: Bitcoin’s strength lies in our ability to choose and enforce the rules that best uphold the network’s purpose and integrity. As a self-sovereign participant, I choose to reject the notion that Bitcoin must accept everything in the name of “freedom,” especially when that freedom can be cynically exploited to Bitcoin’s detriment. Instead, I align with the principle that some judicious constraints, whether at the software policy level or the community social level, are necessary to keep Bitcoin healthy, useful, and legally accessible to all. This is a nuanced position, and it may be polarising. Some will accuse me of advocating “censorship” or betraying Bitcoin’s neutrality. I respect the purist viewpoint, but I humbly disagree in this case. Refusing to store illegal content is not tyranny; it’s common sense. We can defend freedom of transaction without turning Bitcoin into a sanctuary for the worst humanity has to offer.

In my book on self-sovereignty, I wrote that with great power comes great responsibility, running a Bitcoin node is indeed powerful, and it’s up to each of us to act responsibly with that power. Today, responsibility calls for vigilance about what changes we adopt. I am communicating these thoughts as part of my ongoing effort to ensure Bitcoin remains future-proof. “Future-proofing” Bitcoin doesn’t just mean scaling it or boosting hash rate; it also means safeguarding its social acceptance and moral foundation. By voicing dissent, by switching implementations, by potentially forking if needed, we the users are stress-testing Bitcoin’s resilience in exactly the way it was designed to be: from the bottom up.

Bitcoin’s story has always been about empowerment of the individual. This current saga, the Node Wars over OP_RETURN and content, is yet another chapter in that story. I, for one, am determined to see Bitcoin thrive as a tool of financial liberation, unsullied by association with illicit content. It may ruffle feathers now, but principled stances often do. As the saying goes, “Bitcoin is for enemies”, but that doesn’t mean we have to let enemies turn it against us. My hope is that through self-sovereign action and frank dialogue, we will navigate this challenge and emerge with a Bitcoin network that is both freer and more secure, a network that can confidently serve the world for decades to come, without any shadow of disgrace on its ledger.

The choice is in front of us. By October 2025, Bitcoin Core v30 will normalise the relaying of arbitrary, potentially illicit content across the network. If we do nothing, if we keep quiet, then we silently consent to this shift. As Bitcoiners, we must ask ourselves: do we want our blockchain remembered as the foundation of sound money, or as a storage ground for abuse?

I’ve made my decision, I run Bitcoin Knots, I reject services that endorse Core v30, and I will defend a “clean” Bitcoin that remains worthy of global trust. The question is: what kind of Bitcoin are you willing to stand behind?
