If your project relies on GitHub, now is a good time to seriously consider hosting copies of your repos using ngit.

[The Tor Project @torproject]

We are grateful to @OpenSats for their grant in support of crucial onion service features and improvements!

[OpenSats @OpenSats]

The @torproject and WireGuard are two major projects supported by OpenSats.

Seeing @BlitzWalletApp recognized as one of the top projects still feels surreal.

OpenSats gave me the opportunity to dedicate my time and energy to building Blitz, and I'll always be grateful for that support.

Nym21 has been an OpenSats grantee since December 2024, with his grant renewed in July 2025. That support lets him work on the Bitcoin Research Kit full-time and keep it free to use, verify, and self-host.

[Matt Cole @ColeMacro]

We are expanding our Bitcoin Stewardship Commitment to support @OpenSats' Red Team Fund, which backs researchers red teaming critical Bitcoin software. This joins our ongoing support for @bitcoinpolicy on sound Bitcoin public policy and @bitcoinbrink on open-source Bitcoin development.

AI capabilities are advancing rapidly, making vulnerabilities in Bitcoin software easier to find and exploit. Bitcoin’s defenders need access to the best available AI models and the compute required to use them at scale, helping them find and fix vulnerabilities before attackers can exploit them. We are grateful to @Rob1Ham, @callebtc, and the broader Bitcoin Red Team for their critical work to date.

Protecting the network that underpins our most important asset is prudent long-term stewardship and part of our fiduciary responsibility.

For additional context, see the @Strive Bitcoin Stewardship Commitment:

[OpenSats @OpenSats]

OpenSats has allocated $36,688,950 USD to free and open-source projects and sent ~41.9 billion sats to 426 grantees in 40+ countries.

Our guiding principles keep us focused and efficient. 🧡🌐

[Unchained @unchained]

If you're contemplating getting set up with Unchained, taking action within the next few days will simultaneously support @OpenSats bitcoin security research.

Helping a friend get started via our new referral program is another way to contribute to this initiative.

[Bitcoin Policy Institute @bitcoinpolicy]

Today, Bitcoin Policy Institute and a broad coalition from across the digital-asset ecosystem are publishing an open letter calling on the world’s leading AI labs to provide qualified open-source defenders with trusted access to frontier AI models.

The past several weeks have made the need for this abundantly clear. The people defending digital-asset infrastructure and open-source software need access to the latest AI capabilities to perform comprehensive security reviews and stay ahead of increasingly sophisticated adversaries.

The coalition includes open-source development organizations, major custodians, treasury companies, payment services, security firms, capital allocators, and others whose businesses and customers depend on the integrity of open-source infrastructure and libraries.

Open-source defenders often occupy the least privileged position in the AI security landscape. They have limited access to the strongest internal cyber models and are frequently blocked by guardrails when using publicly available frontier systems for legitimate security research. As a result, they often resort to less capable open-weight alternatives.

We are urging frontier AI labs to establish a clear, trusted pathway for qualified open-source and digital asset defenders to access their strongest capabilities, with sufficient compute and secure environments to conduct meaningful security reviews. Frontier AI could become one of the most powerful defensive technologies ever developed, but only if defenders get fair access to those systems.

It’s time to give defenders the tools they deserve.

[Rob Hamilton 🟥 @Rob1Ham]

Yesterday I began fully integrating the @OpenAI trust cyber program into my Bitcoin Red Team efforts.

This morning I woke up to see this.

I am now being blocked from doing additional analysis on a codebase which I've already responsibly disclosed to, and have received confirmation had legitimate findings.

To be clear, this is after having already KYC'd and completed the onboarding process months ago to use the cyber capabilities OpenAI has to offer.

I am now prevented from being able to continue the investigation in a further effort to make sure their code changes are sufficient, as well as understand if there are other issues that have yet to be discovered.

It absolutely guts me as a patriotic American to have to do this, but I will be going back to using Chinese open source models to conduct my research to protect Bitcoin infrastructure.

Black hats will not hit these issues. The white hats will. We've hit a local minima in policy. Intelligence is unrestricted for those who don't follow rules, and those who engadge in harm reduction are left on the sidelines.

What are we doing in this country? How is this keeping people safe?

Please do something @DavidSacks @sama @realDonaldTrump
