@Blink Wallet has published a post-mortem on the September 19 attack, describing what happened and how they handled the crisis:

The September 19 Attack — The Facts, The Full Story and Announcing The 50% Bounty (up to 3.3 bitcoin)

How an attacker used a flaw in our admin tools to take 6.61 BTC from 24 accounts, how every one was restored, and what we have changed.

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. ⚡

⚡ To all Bitcoin book authors 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. ⚠️ Please SHARE this post with a Bitcoin book author if you happen to know one.

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: 1. Morality can be derived from physics. 2. More specifically, it is an emergent property of the social network structures that exist within a reality governed by the laws of thermodynamics. 3. 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.

UPDATE: Bitcoin Standard in Polish Parliament 🇵🇱 560 copies of #TheBitcoinStandard by @saifedean — packed and ready to ship! 📦📚 They’re heading to every MP in the Polish Parliament next week when the new session begins. Each book includes an open letter from the Twenty-One Community highlighting Bitcoin as the first inflation-resistant, censorship-resistant monetary network of the digital age, outlining Poland’s growing Bitcoin ecosystem, and calling for thoughtful regulation. (Polish original and English translation of the open letter attached.) #BitcoinStandardPL #BitcoinWSejmie

My Fellow Nostriches, 🚀 Dwadzieścia Jeden - the Polish Bitcoin community - has just launched a #Geyser project to purchase 560 copies of “The Bitcoin Standard” by @Saifedean Ammous. 🎯 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: bitcoinparliamentpl@geyser.fund ⚡ 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! #BitcoinStandardPL #BitcoinWSejmie

Pneuma is breath. In Stoicism, it is the spirit—the very seed of all life. 'Become pneuma' is perhaps the most powerful meditation instruction. Focus on breath to become breath. Enjoy... #Tool #tunestr #meditation

Yesterday's performance by Trump and Vance was not a display of power. It was a theatre for the crowd, underpinned by narcissism and helplessness. To be honest, it was quite pathetic. (Art by Matylda Damięcka / Radek Łukasiewicz)

Soon, the Polish edition of the book "Broken Money" by the brilliant @Lyn Alden will be published by Freedom Publishing. I had the great pleasure of working with the publisher as a consultant on the Polish version of the book. The book doesn't need advertising here on nostr, but I am glad it will reach a wider audience of Polish readers. You can also become a patron of this edition today, which I warmly encourage. More information can be found on the publisher's website:

This is a significant pivot. I'm pleased to see Zuck's change of heart. Nostr paved the way, X followed, and now Meta is joining the free speech renaissance. The others will either follow or be left behind. https://www.instagram.com/reel/DEhf2uTJUs0/

I’m thoroughly enjoying Resistance Money by @npub1yezu...awc7, @npub1jddn...4s60 and @npub10afr...0xj0. It has made its way into my top five Bitcoin books! #bookstr

Let’s not lose sight of the fact that achieving ideal price stability (0% inflation) is still theft.

Don’t overlook this sentence in the Preamble of MiCA: "Hardware or software providers of non-custodial wallets should not fall within the scope of this Regulation." [see: Item (83), Preamble, MiCA] It shows the way forward. #MiCA

GM, Happy White Paper Day to all!

Those who do not understand freedom technology often lack a true understanding of freedom itself.

Apparently, we have zapped each other 19.41486219 BTC as of now—just a little over 1.1 million USD. It’s great, and it’s still early.

I am referring only to the style of this debate. Saif often finds himself at a low point, as he seems to ignore or misunderstand the repeated points and resorts to unfounded ad hominem attacks. In the section on 'identity bias,' he appears completely lost. In contrast, Konstantin behaves like an adult, remaining focused and composed under pressure.
