TwentyOne.Life is dedicated to building sovereignty brick by brick. From money to food, from health to privacy, Bitcoin is the foundation for freedom in a world distorted by fiat. I write about sound money, proof-of-work, and the Sovereign Stack: Money. Health. Data. Attention. Energy. My new book Brick by Brick: Building a Sovereign Life on Bitcoin is now available for pre-order on 👉Fiat Amazon (english) https://amzn.to/4mW2pK4 👉Fiat Amazon (german) https://amzn.to/47eLMD6 👉BTC (english, german) https://twentyone.life/shop Join the movement. Build sovereignty. Opt out, don’t wait.

A circle you can verify.

Thinking about the same. I haven’t used most of them since over two years. Maybe I will remove my profiles and close the accounts. 🤔

I would build a solar Farm and a tiny house. I would mine BTC an reuse heat for heating and warm water.

I have now fully open sourced the code which creates this on-chain BIP-444 futures contract!

The contract starts with an atomic deposit into the contract address of 1 BTC each (to make sure both parties put in the same amount into the contract address).

Context: BIP-444 makes the use of OP_IF & OP_NOTIF consensus INVALID upon activation.

The contract is built as follows:

The taproot address uses the NUMS point as described in BIP341, to provably show the key path is not active.

We have two parties, a "YES" (444 activates) and "NO" (444 does NOT activate). YES and NO for short.

The first leaf is a 2 of 2 multisig of both parties. This exists to be able to self send the UTXO AFTER BIP 444 activates. This is because BIP-444 just added a clause that UTXOs created before activation will NOT have the BIP-444 consensus rules applied to them. This self send removes that exception.

The second leaf: has 2 ways you can spend with it, a 2 of 2 (YES and NO) multisig, just like the first leaf OR the NO party, with a time lock which is LESS THAN the third tap leaf. This is important because it uses OP_NOTIF

The Third Leaf: The YES party can spend, after a time lock AFTER the second leaf.

The order of the timelocks is important. If BIP-444 activates, the spending condition that can spend before you will be consensus invalid, so it doesn't matter if you believe 444 activates.

So to summarize:

- If BIP-444 DOES activate, the party who believes it will be able to use the second tap leaf to get 2 BTC out.

- If BIP-444 DOES NOT activate, the party who believes that will use the third tap leaf to get 2 BTC out.

Since each side is highly confident in their position, the fair market price is a 1:1 ratio, implying 50% likelihood.

With 85 days until activation, this contract as written gives you an implied ~430% APY on your bitcoin! The risk is being incorrect on your opinion of BIP-444 activating.

You could modify the collateral each side puts up to get different implied odds of the futures contract as well.

Anyone who wants to take the BIP-444 WILL activate side, let me know! The Author of the BIP has agreed to this, I have already asked for a larger bet size beyond the 1 BTC I initially proposed, but I have more!

I thing a dirty information war is upon us regarding the “soft fork BIP-444” an no need to poor more oil into the fire 🔥

I would prefer a more educational approach.

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.

Very proud to announce my newly published book today, at the Bitcoin Whitepaper day! #bitcoin #whitepaperday #twentyone #twentyonelife

Let’s build more and consume less!

That’s exactly the point of running your own node, you decide your relay and validation policies, and I decide mine. If my node doesn’t relay your BIP47 or tx0 transactions, it’s because I’ve chosen tighter policies to reduce unnecessary data and long-term storage risk. You can route around it, that’s how Bitcoin’s peer network is designed to work.

Knots isn’t “propaganda.” It’s Bitcoin Core with additional configurability and better defaults for people who take node sovereignty seriously. Both Core and Knots enforce the same consensus rules, neither breaks Bitcoin, and both coexist perfectly fine on the network.

If you prefer to relay every kind of transaction, go ahead. Others choose to run leaner, more conservative nodes to avoid bloat and potential legal or operational risks. That’s not brainwashing, that’s responsible node operation and informed choice.

Pruning nodes have many disadvantages see below. Most important you no longer allow other new nodes to sync the full block chain.

• Cannot serve old blocks to other peers (no full blockchain sharing)

• Cannot enable txindex=1 (transaction index for querying by txid)

• getrawtransaction RPC fails for non-wallet transactions

• getblock RPC fails for pruned blocks

• getblockstats and similar historical RPCs fail for pruned data

• Full wallet rescans from before the prune height not possible

• Importing old private keys may miss historical transactions

• Electrum servers (Electrs, Fulcrum, ElectrumX) cannot run

• Block explorers (e.g., Esplora, BTC RPC Explorer full mode) cannot run

• Ordinals or inscription indexing not possible (requires full witness data)

• Taproot asset / Taro / RGB indexing not possible

• Lightning Network nodes (LND, c-lightning, etc.) have limited functionality or require workarounds

• Historical audit or channel verification for LN not possible

• Custom chain analytics or forensics not possible

• Sidechain / drivechain validation not possible

• Compact full rescans or data rebuilds (reindex=1) require re-downloading the chain

• Cannot act as a seed node or contribute to network data redundancy

• Some RPCs for proofs (gettxoutproof, verifytxoutproof) may fail

• Cannot run full-featured Bitcoin API or explorer services

• Cannot archive or share complete historical chain data

I don’t care how you or others use Bitcoin, that’s the responsibility of everyone. I don’t want to store illegal content on my own node, that blows up the nodes storage. This will make running a node more expensive over time and can lead to higher centralisation.

⚠ BITCOIN CORE v30.0, PLEASE READ ⚠

HOW TO INSTALL?

1. Stop Bitcoin.

3. Download "bitcoind.s9pk" from the bitcoin-core-startos Github release page. https://github.com/Start9Labs/bitcoin-core-startos/releases/tag/v30.0

4. In StartOS, navigate to System -> Sideload a Service

5. Upload bitcoind.s9pk

WHY DOWNLOAD INSTEAD OF MARKETPLACE?

Knots and Core share the same ID. This allows dependent services, such as lightning, to use either one. It also allows people to switch between them without needing to resync the blockchain.

Due to a bug in StartOS 0.3.5.1, if either service goes up in version, it will show as an "update" for the other service. This sucks and has caused people to think StartOS is trying to trick them into switching. To minimize confusion and mistakes, we release new versions of Knots and Core in parallel and require explicit action for switching. Not ideal, but a decent stop gap until StartOS 0.4.0.

Because there is no Knots v30.0, listing Core 30.0 on the marketplace would result in Knots users forever seeing Core v30.0 as a "update". As such, we are making Core v30.0 available as a download/sideload instead of listing it on the marketplace.

Consider making Knots default Bitcoin client and core as optional.

Personally, I’d lean toward stacking Bitcoin while using the job to fund skills and side projects. That way you keep optionality, Bitcoin as a savings vehicle, and business ideas you can test without burning the lifeboat too early.

I've been thinking a lot about my nearly 15 years away from the Greek Orthodox Church.

I've come to this conclusion - I don't know if I would have the same ethical values without that upbringing. It's easy to think I would when I had that foundation since birth, but I no longer think it's that simple.

I've been around a lot of secular people. Not all, but many are in a dark place. People who are missing something from their lives. Ones who didn't have an upbringing similar to mine.

I've begun to wonder if these people would benefit from religion in their lives. Some type of positive power to pull them out of the darkness.

I'm not saying I've found Jesus. I haven't.

But more and more I want to be around the people who have.

Because I can't really be around these other people any more. My wife & I have cut most of them out of our lives at this point.

We prefer to spend our time around positive people who are working on building better lives. Building families. Nearly all of them are religious.

We're both very logical people. Religion and logic were like oil and water to me.

But when I look at the state of the world, it's not hard to see the positive impact religion can have on people. That's a very logical conclusion I'm coming to.

Also, I miss a lot of the Greek cultural stuff that I grew up, and it's intertwined with the church. It would be strange, but I'm accepting the idea that returning there, even as someone who isn't religious, feels more right than not going.

Still working through this but wanted to share.

Because bitcoiners are how I got here. The ones having families, going to church, and being decent human beings. Those are the people I want to be around.

The alternative is despair and darkness, and I am not going down that road.

✌️🧡

I think that’s quite natural if you are getting older, as we all do.

🌍 Proud moment on my sovereignty journey: my Bitcoin Knots node is almost fully synced (95%+).

Running a full node means I’m not just holding sats, I’m actively supporting the Bitcoin network. It’s about taking responsibility, verifying for myself, and laying the baselayer for a sovereign life.

This isn’t just about tech. As I wrote in my book Brick by Brick: Building a Sovereign Life on Bitcoin, sovereignty is built one choice at a time. For me, running my own node is one of those bricks.

We don’t outsource freedom. We run it. We verify it. We build it.

I lived for 6 years in the UK, what a disaster how a country can be destroyed. Many of my UK friends moved to Canada already.

I joined OrangePillApp in Jan ’25, paid for lifetime access, and reached out to Bitcoiners worldwide for my book. I was especially looking for Bitcoiners already living on a Bitcoin standard to share their Orange Pill stories.

The result? Account banned, sats confiscated, branded a “spammer.”

Even Bitcoin-branded apps can act like fiat platforms.

This experience will be included in my upcoming book Brick by Brick, where I share Bitcoiners’ stories and the lessons we learn along the way. More information can be found here: https://drive.google.com/file/d/18JsOS66bjcez-OI23psERJ8aT1Q0IEGI/view?usp=drive_link

Hi, I like your Art and as I am writing a Bitcoin book I was wondering if you are interested to design a book cover for it? I also look for life stories of people living a Bitcoin standard to complement, contrast my own journey. If you or anyone is interested please DM me.

“There’s no fiat bailout for your health. Choose wisely.”

Once your health breaks, no money can fully buy it back. The fiat system promotes sickness; sovereignty means owning your health choices, starting with real food.

#CarnivoreKeto #HardChoices #twentyonelife #carnivore #fiat # realfood

“Don’t outsource responsibility. Self-custody is self-respect.”

Leaving your Bitcoin on an exchange is trusting someone else with your future. True ownership means taking full responsibility, just like in life.

#BitcoinOnly #SelfCustody #twentyonelife

“Fiat steals your time ⏳ Bitcoin gives it back.”

Fiat currency inflates away the value of your labor. Every hour worked is worth less tomorrow. Bitcoin, by contrast, preserves value across time. It respects your effort.

I thought about writing a book, elaborating on how a Bitcoin Standard would impact our world from different viewpoints, e.g. health, finance, industries, lifestyle and so on. I got the idea to ask different people who live on a Bitcoin Standard to write a chapter about their own journey. Would anyone be interested in sharing your story? Please contact me if you are interested, and Zap if you would liker to support my project. #bitcoinstandard #project #education
