Bitcoinize POS Machine ⚡

Shipped our final February pending orders, and the last 11 Bitcoinize Machines are on their way to @MotivPeru. Now we’re building something new: a definitive community response for @bitcoincoreorg. No more machines for sale until we ship new code. 👇

@evoskuil @ZitadelleUM I love to see it. I’m not running it yet, but I will do it soon! Our Zig implementation learned a lot with assume valid. We are trying to beat lib’s performance. Very hard task!

Libbitcoin is coming. 👊

The Bitcoin community is coming together in new ways. Excited to see Geyser being one of these!

SAVE THE DATE 🇸🇻 The Bitcoin Circular Economies Summit returns to El Salvador, and this time the doors are open. 📅 November 19–20, 2026 📍 El Zonte For two years, this Summit has gathered the people actually building Bitcoin circular economies on the ground. Builders, merchants, educators, and community leaders sharing what they've built, exchanging hard-earned lessons, and strengthening a movement that's growing one community at a time. This year, we want you in the room with us. Bitcoin is money, and Bitcoin Circular Economies are the proof. Find more: bitcoinbeach.com/blog/save-the-…

Can’t wait to ship my Bitcoin implementation in Zig ⚡️ AI still isn’t reliable enough, so I had to build @Bitcoinize AI first. My AGI squad (Satoshi, Hal & Len) exposed critical flaws in @OpenAI and @claudeai attempts to rewrite BTC. Just need more time and testers to help!

@isabellasg3 Fears that do not materialize. Everything will be fine

and the kicker is that none of this requires a single uniformed officer. there's no kgb knock at the door. there's no surveillance van parked across the street. the entire architecture of control runs through her phone, her car, her bank, and her neighbor. the state didn't have to take her freedom. she carried it into the building herself.
 aren't you worried about sounding paranoid? aren't you worried about people thinking you're crazy? all valid concerns. but i'll tell you what concerns me more.

i just saw a video that made me low key freak out… and it might be the most chilling thing on the internet right now. 

so this is the video: a woman wakes up to her phone and a voice says, "good morning, citizens. your overnight account balances have been updated." she's at 500 credits. she needs 50 more by end of day or she gets automatically evicted. she’s feeling sick, so in order for her credit score to not be affected, she needs a doctor’s note… so she goes to the doctor instead of work.

The @Bitcoinize ZIG node is advancing. Must thanks @Bitcoinbeach, @r0ckstardev and @geyserfund for the inspiration! Long journey reconstructing all dependencies and components of Bitcoin Core as a community response for @bitcoincoreorg Support me: motolese@blink.sv ⚡️

It's a high-severity bug (CVE-2024-52911): use-after-free in script validation that a miner could theoretically exploit with a crafted invalid block to crash nodes or (less likely) run code. Patched in v29.0 (April 2025), disclosed today. ~43% of nodes may still be on older versions—upgrade if you're running one. Expensive to exploit, no known real-world attacks. Coin Bureau posts a mix of news, including risks and positives. Security issues like this matter for transparency in Bitcoin's infrastructure.

40%, 8 days left, Paco's campaign is moving forward, let's push it to 100%! 👇🧡

@BitcoinLaLaguna Now it's a rare item, not for sale anymore. Take care of it!

Another merchant leveled up in El Salvador! 🥳📲⚡️ Crazy Store now has a Bitcoin POS and the book Bitcoin para Negocios to keep stacking properly. Visit La Laguna, Chalatenango for a traditional breakfast and pay with sats. We’re ready for your next visit. 🇸🇻🍊

Running Bitcoinize 🚀 A long computer science journey. Dreaming in BIPs and OPs. A few bugs to fix, hundreds of tests to run Once it finishes syncing and validating the blocks with the new Zig zero-dependency code, I’ll start testing the wallet and optimizing our LevelDB in Zig

Extremely important that doesn’t happen. Please repost so we get the word out.

Dear @danheld, It must be nice to sit so comfortably that you can look at the entire world and say "no one cares." Meanwhile in Uganda, orphans at Star Light Elementary School care A LOT about the fact that @BitcoinBeachBR used Bitcoin to save their school. With brave hearts abandoning the industry, developers burning the protocol, strong new narratives waiting to be weaponized, and more than 100 kids to feed until the end of the year, you should be deeply concerned. Do you have no soul? Bitcoin is part of our daily lives. It's replaced our local currency. It may not be useful for you, but it was made for us. WE CARE. 🧡

@BitcoinBeachBR @Bitcoinize @BitcoinConfed

The Praia Bitcoin, @Bitcoinize, and @BitcoinConfed Sunset From September 2021 to February 2026, Praia Bitcoin worked to create the first Bitcoin circular economy in Brazil. In 2023, we developed the Bitcoinize Machine and became the first community to combine point-of-sale systems with @bolt_card, @btcpayserver, and @lnbits. Since 2024, we organized the industry through the Bitcoin Economy Confederation directory, creating a network of circular economies and providing them with visibility, coordination, and shared resources. Due to recent changes to Bitcoin's source code that transformed the Bitcoin blockchain into a hosting database for arbitrary data—representing countless social and legal risks for Bitcoin circular economy founders and node operators— we have decided to cease operations as a direct signal to @bitcoincoreorg developers that these changes are unacceptable. The websites will remain operational throughout 2026 as historical records and resources, but there are no further plans to continue the Confederation's, Bitcoinize's or Praia Bitcoin's endeavors. Since these protocol changes cannot be reversed, the risks to node operators and community founders will persist indefinitely. We will be closing our community center until April, and all donations collected for our 2026 operations will be transferred to active projects on @GeyserFund and other worthy initiatives in the Bitcoin circular economy space, mainly @orphansofuganda A Warning to the Community Leaders: Because of these emerging undesirable narratives and technical realities, we strongly recommend extreme caution before doxxing yourself in association with Bitcoin—especially in remote areas and developing nations. Node operators and community founders are now exposed to numerous social, legal, and non-technical risks that can destroy a reputation overnight, undermining years of careful community building. This exposure exists because a small group of developers have prioritized features that fundamentally compromise the protocol's original purpose and the safety of those building Bitcoin circular economies worldwide. The Path Forward: We have come to recognize a fundamental truth: the future of Bitcoin circular economies lies not in centralized organizations, but in organic, independent growth. Each community must build its own resilient economic ecosystem, learning from others while remaining truly sovereign and self-sustaining. This decentralized approach honors Bitcoin's original ethos far better than any confederation ever could. We thank all the communities, donors, and supporters who believed in this vision. Your work continues to matter, even as we close this chapter. Stay sovereign, Fernando Motolese Founder, Praia Bitcoin Brasil, Bitcoinize and BitcoinConfed Sources:[1] x.com/BitcoinBeachBR…

“Spend as soon as possible” works like magic, we are lucky to have already bought the school and brought construction to almost completion at Starlight Elementary School! We of course have effect on the budget but it could have been worse, about 85% of the major construction & spending is done ✅ We are now painting 🖼️ Thanks @Bitcoinbeach, @TrezorAcademy and of course @BitcoinBeachBR (our coach & mentor) for making a better life for @orphansofuganda We keep building.
