Is Bitcoin a Captured Project? Reflections After the BIP-110 Fiasco
The most important question in Bitcoin right now is whether it is a captured project. The short answer is: we do not know yet.
On the one hand, miners managed to ignore a change proposal that did not undergo URSF. Whether they colluded or not does not matter. The crucial point is that three mining pools could decide the fate of the network. That is scary as fuck.
On the other hand, BIP-110 was a minority soft fork supported by approximately 20% of nodes. Would miners have behaved differently if BIP-110 had managed to convince a majority of the network? We do not know, but that is also scary.
At this moment, I think a hard fork is a premature idea. Before unleashing this demon, we should figure out how to test the network and answer the question above: do nodes control the network? Would it matter, for example, if a majority of them supported BIP-110?
To do this, we need a BIP that can convince more users.
Apart from this, we should focus on:
Supporting the development of competitive and conservative node implementations. We have Knots. We have the Production Ready idea. That is a start.
Supporting the decentralisation of mining.
We should also thank the Roughnecks. They have fallen in battle, but they will remain legends.
For now, we should all return to the legacy chain and work on putting it to a new test. One that will allow us to find out whether node runners are at the wheel or not.

Bootstrapping Vicious Circle 💀
No one offers products/services for sats → because no one accepts sats for products/services → because no one offers products/services for sats.
The goal is to break it.
Start offering your products or services for sats even if: • there seems to be no market yet • it costs you something • it feels inconvenient right now
Play the long game. Bitcoin is here to stay. Those who build the Bitcoin economy early will be rewarded later. ⚡

Too many of your books are only available for fiat on Amazon.
This is disappointing.
You expect people to adopt Bitcoin, yet you don’t make it easy for them to pay you directly in sats.
Keep Amazon for no-coiners. That’s fine. But why not offer both?
Your Bitcoin readers want to pay you in sats without feeding the big tech behemoths. Make it possible. Practice what you preach.

The Network Theory of Ethics
Here is the thesis I’ve been working on for some time. It deserves a treatise, and I am currently working on one. Still, I am posting it here on NOSTR because I know many of you will challenge it. And that is exactly what I need.
I’ve dubbed it "The Network Theory of Ethics". It claims the following:
Morality can be derived from physics.
More specifically, it is an emergent property of the social network structures that exist within a reality governed by the laws of thermodynamics.
Moral values arise when individuals (nodes within a social network) create and maintain the social fabric in a reality in which energy dissipates and in which the expenditure of energy is required to temporarily reduce entropy within the network.
More to come.
Please share this with anyone you think may contribute to the discussion.

LND Recovery from Backup (exact UI flow)
I’ve analysed the LND recovery process on Umbrel step by step, based on the Lightning seed + Static Channel Backup (SCB) recovery model used by Umbrel.
I’m attaching notes covering the two main scenarios:
If your Umbrel decides to stop cooperating one day, this is exactly what will happen during recovery — including the intentionally force‑closed channels and the wait for funds to reappear on‑chain after timelocks.
Knowing this in advance should make it much easier to prepare properly and spare some unnecessary stress.

Desire is a misery factory. Clinging to money, status, power, pleasure, possessions. Learning to let go of it is the deepest act of self-compassion. It’s how true peace emerges.

Hey Nostriches,
We’re almost there! 🔥 Our mission to fund 560 copies of The Bitcoin Standard—one for every Polish MP—is nearly complete. We’re just a couple hundred thousand sats away from the finish line.
Right now, Poland is in the middle of a heated debate about a new law on “cryptoassets.” Most of the political class is still clueless about Bitcoin. That’s where we step in—with education, not speculation.
✅ Books funded by the Bitcoin community via Geyser ✅ Purchased directly with bitcoin (no selling bitcoin to make the purchase) ✅ Each copy will include an open letter stressing the importance of understanding Bitcoin ✅ We’ll promote the project in Polish media to spark a public discussion about Bitcoin
📌 Project details:
https://geyser.fund/project/bitcoinparliamentpl
🫵 Ways to contribute:
➡️ Zap the project’s nostr profile:
➡️ Send sats anonymously to LN address: [email protected]
(Note: Geyser requires a minimum of 1,000 sats per contribution.)
💡 Let’s help educate Poland’s lawmakers about Bitcoin. Every sat counts!

Michael Saylor’s playbook directly attacks the financial system’s ability to co-opt and extract rent from base money. That’s why legacy banks began treating him as a mortal enemy. Remarkably, the state itself has largely stood back — and now appears to be choosing sides. That choice will signal whether the transition is smooth or tumultuous.

My Fellow Nostriches,
🚀 Dwadzieścia Jeden - the Polish Bitcoin community - has just launched a #Geyser project to purchase 560 copies of “The Bitcoin Standard” by
.
🎯 The mission is to gift one copy to every member of the Polish Parliament.
Why? Because we believe:
➡️ Education changes minds—some lawmakers may rethink their stance on Bitcoin.
➡️ Knowledge shapes policy—especially as Poland prepares new crypto asset regulations.
➡️ Visibility matters—this initiative could spark media coverage and boost Bitcoin awareness nationwide.
This is a global, Bitcoin-only campaign, and every satoshi counts. If you believe in Bitcoin’s future, help us plant seeds among policymakers.
You can support the campaign:
⚡ On Geyser: geyser.fund/project/bitcoinparliamentpl
⚡ Via LN address: [email protected]
⚡ By zapping the campaign's profile on NOSTR: njump.me/npub1jmfc0zs27qq2kpj47hel0aclsj4qf665yvd36v655ft4zddt4xrqv38t5a
Big thanks to 🙏🏻 Freedom Publishing 🙏🏻, the Polish publisher of The Bitcoin Standard, for backing the campaign! Thanks to their support, we’ve secured a solid discount—and yes, we’re paying in Bitcoin.
💪 Let’s make this happen together. Follow, donate, zap, share—and help us orange-pill the Polish Parliament.
Happy stacking, and thank you for being part of this!

We've been chained to reality and conditioned to fear it. But as chaotic, noisy, and fearful as reality may be, it is also constantly underpinned by silence. Meditation helps us find that silence and spend time in it. This dissolves the chains and uproots the fear, allowing us to be free and happy.

'The Ethics of Liberty' by Rothbard is a great read, even if you don’t agree with everything he writes. Although I am personally closer to Mises, Rothbard’s talent for rigorous logical reasoning is truly impressive.
#bookstr #Rothbard

🧘🏻♂️ A few meditation instructions for those who practise daily 🧘🏻♂️
Disclaimer: I apologise if this sounds like gibberish. Language is a blunt tool.
What is happening now? And now... And now... And now... Second by second. Meditation is about the relentless noticing that all contents populating consciousness (images, sounds, sensations, thoughts) remain in a state of continuous change, whether we want it to or not.
Where is the silence?
Even in times of unrest and chaos, stillness is present and permeates everything. Seek out this silence, find it, and try to spend time within it. Use the silent space as a vantage point for observing and noticing whatever is happening now. And now...
Where am I? What am I? Who am I?
In the silent space, you may notice that, among other things, the Self is also present. It’s that feeling (contraction?) that you are you. It’s the part of you that wants or doesn’t want things, that desires and protests. It’s the part that refuses to let go. Notice it and return to the silence. And again. And again.
Everyone’s inner space is different. Please share your tips on how to practise.
With metta.

Thanks for the Alby Hub’s Friends & Family feature! I used it today to set up a sub-account for a family member, which I connected to Alby Go. It’s perhaps the easiest way to onboard close contacts without relying on third-party custodial services.
That said, I would appreciate the following additional capabilities:
— A separate balance for the sub-account in the main account’s UI (currently, payments to the sub-account are merged with those of the main account and are indistinguishable)
— For the main account owner to spend from the sub-account’s balance, it should require deleting the sub-account (in this case, the balances should merge)
— An LN address for the sub-account
Additionally, I have not found a way to reconnect an existing sub-account to a new Alby Go instance. Is it possible to display the secret code again when the sub-account is already set up and running?
Anyways, great stuff! All the best.
