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. 👇

Most people think their private group chats and assets are safe from state surveillance, but relying on centralized apps and legacy laws leaves your entire Bitcoin operation exposed to government overreach.

In this new episode, Renata Rodrigues (@lobaestrangeira) and Daniel (@inahcitadel) explain how communities are walking away from this trap by building un-surveillable networks and off-grid physical sanctuaries.

Organizing a community on standard messaging apps creates a massive honeypot for regulators, but the open-source Fedimint protocol fixes this vulnerability by allowing you to run secure, zero-custody financial federations. We map out the exact mechanics used to hide group transaction data, which shows how parallel economies can successfully bypass currency bans.

Because digital privacy requires a physical backup, Daniel breaks down the engineering behind the INAH Citadel, which is a 230-acre sovereign outpost in Mexico.

He explains how their team used specific legal trust frameworks to secure absolute land ownership and total water independence.
The parallel infrastructure required to opt out of the legacy system is being built on the ground right now, and you can find the full episode links below 👇

Bitcoinize Core is being written in Zig at the absolute edge of AI coding tools.

+1M lines of AI-generated waste.
+6 months of brutal revision.

Only 100k lines survived human review and deterministic consensus.

Developers are learning to accept deception. The fiat mindset is already inside the model weights.

@Bitcoinize will change that. Bitcoin fixed AI.

@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!

[Geyser ⚡️ @geyserfund]

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.

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!

[Bitcoinize POS Machine ⚡ @Bitcoinize]

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

[Fernando Motolese @MotoleseOficial]

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

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%! 👇🧡

[Bitcoinize POS Machine ⚡ @Bitcoinize]

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

[Bitcoin La Laguna @BitcoinLaLaguna]

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. 🧡

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
