1) AI will not eradicate humanity. Humans survived an ice age, the Black Death, two world wars, and (so far) the advent of nuclear weapons. Anyone who is loudly warning of AI-caused human extinction should not be taken seriously. 2) If you worked in a company where you anticipated a 10% chance that your product would kill ten people, let alone all people, the correct response would be horror, ceasing all operations, and likely contacting the police or other criminal authorities. I am obviously no Coxon booster but at least his behavior is in line with his stated beliefs. Any current AI company employees saying "yes, me too, the thing we are building and about to IPO may kill all humans" should, again, not be taken seriously. Their actions betray their actual beliefs. 3) Antitrust law does not prevent AI companies from coordinating to make sure AI does not hurt people. It does not prevent companies working together to make sure it doesn't hack people; the DOJ and FTC made this clear a decade ago when they issued a policy statement saying that the agencies "do not believe that antitrust is – or should be – a roadblock to legitimate cybersecurity information sharing." The same principles apply here. See: justice.gov/archives/opa/pr/… 4) Antitrust law does absolutely prevent AI companies from organizing to prevent the entry of cheaper, upstart rivals because the bigger companies are burning cash and failing to achieve sufficient profitability. The panic of individual employees may be sincere if misguided, but the moves by their CEOs to achieve some kind of broad "antitrust waiver" or "exemption" should be meet with deep skepticism in light of the economics of the industry and the threat they face from open models.

We're happy to announce two new members of our Board of Directors. Algorand CEO William Herkelrath and Nexus Laboratories Chief Strategy Officer @alexanderfowler have officially joined the board, alongside existing members @billbar and @walexholmes.

To those responsible for the theft of bitcoin from the Liquid Network: Blockstream will not pay a ransom for the return of stolen funds. Taking assets without authorization and withholding their return is a crime, not responsible disclosure. It is not white-hat activity. It is theft. We have engaged in good faith in an effort to secure the return of stolen user funds and protect the broader Bitcoin community. That effort should not be mistaken for acceptance of the actions taken nor of the terms being demanded. We will not be a party to the precedent that open-source software developed for the good of the Bitcoin community should subject its developers to paying a ransom that far exceeds their economic participation. Bitcoin is hard money and can’t be minted without costs, Bitcoin doesn’t haircut users to pay a ransom. To the Bitcoin community: We are fighting for what we believe in, for the users whose funds were taken, and for the principles on which Bitcoin was built. The community has demonstrated incredible resolve with teams of people dedicating their time in support of each other to identify and patch vulnerabilities in each other's products and systems. We are all driven by the mission that Bitcoin is the single best asset, for every person, company, and institution on the planet to invest, use, and build on. The world is a different place with the advancements of AI, and the Bitcoin community has responded with force to combat that threat. Damage has been done, battles have been lost, but on the whole the Bitcoin community is gaining ground in the war with bad actors. We want to thank the community for those efforts, for your support in hardening the network, helping users recover funds, and for your support in our assertion that crime does not deserve rewards. To those holding the stolen bitcoin: There is still an opportunity to resolve this responsibly. The bitcoin can be returned and we can revert to the standard of white-hat principals. However, if the funds are not returned, we will pursue every lawful avenue available to us. We will work with law enforcement, exchanges, service providers, forensic specialists, and other relevant parties to trace and recover the assets and identify those responsible. More importantly, Bitcoin is transparent by design and the community is made up of the most sophisticated engineers, cryptographers, and white-hat hackers globally. Transactions do not disappear, and neither does the evidence they leave behind. We will not pay for the return of stolen property. We will not abandon our users. The Bitcoin community will not stop pursuing the funds. Return the bitcoin.

Hey Anthropic! I reported these encryption issues to you in May and you told me there was no relevance because replay attacks were not in your threat model. And now apparently you’ve been watching people exploit them for months. I’m actually kind of annoyed!

LIQUID NETWORK UPDATE: OPERATIONS RESUMED, RECOVERY ONGOING Status as of September 10, 2026, 10:00 UTC Recovery Status The Liquid Network has entered the next phase of its controlled resumption. As a precautionary measure, block production has resumed without transactions while the network is monitored to confirm full stabilization. Blockstream confirms that the required functionary and bridge node updates have been successfully deployed. Functionary nodes are signing and validating blocks as intended. Peg operations, including PAK-authorized peg-outs, remain suspended while work continues on the final recovery stage: restoring the BTC/LBTC reserve is in progress. Reminder: Beware of Scams There are reports of scammers attempting to exploit the situation through fraudulent update sites and messages. Please rely only on official Liquid Network and Blockstream channels. Never send funds or disclose private keys or seed phrases in response to unsolicited communications. Thank You The Liquid Federation and Blockstream sincerely thank the broader Bitcoin community and security teams for their assistance and continued support during this challenging time. Safely restoring full operations remains the highest priority.

1/ Today we're releasing Lattice Jolt: a post-quantum version of the Jolt zkVM, built on lattices instead of elliptic curves. It's _faster_ than curve-based Jolt and has the shortest proofs of any post-quantum zkVM — under 100 KB. Post: a16zcrypto.com/posts/article…

@liquid_btc security release coming up, with network resumption plan. been a busy few days, more details to come.

Every message the attackers send makes it clearer their claim of being whitehats is absurd. Whitehats don't steal funds without a reasonable disclosure attempt, don't hold funds hostage with extortionary struggle sessions, and don't unilaterally take a made-up % of stolen funds. These charlatans should be hunted down by private sector mercs and forced to hand over the stolen funds by any physical means necessary.

RT @Excellion: Update: @side_swap has sent the ~4 BTC in fees it collected on the hacker's 4,000 BTC peg-out back to the @Liquid_BTC Federa…

If you are a lab researcher, I urge you to consider what the next few years will actually feel like. Do you want to kick off a superintelligent RL run without a rigorous understanding of its mind? Should you put your head down because “it’s happening anyway” - or take this moment to call for different conditions?

We’re sharing a solution to the Navier-Stokes Millennium Prize Problem, one of the deepest problems at the frontier of mathematics. The proof was produced by a group of agents, using an OpenAI next-generation model significantly more capable than GPT-6 Astra. The problem concerns whether the description of smooth three-dimensional fluid motion modeled by the Navier-Stokes equations can break down. It has remained unresolved for roughly 90 years.

We are aware of a security incident on @Liquid_BTC. Purported white-hat hackers have withdrawn ~4,000 BTC (~$320 million) from the Liquid Federation wallet. The @Blockstream team is working on contacting them on-chain with a signed message. What we know so far is that the funds were withdrawn via the SideSwap PAK (Peg-out Authorization Key), but that key was not compromised, nor were any others. Exchanges have been notified and have already paused (or will pause) LBTC deposits and withdrawals. Other Liquid assets such as USDT, DePix, and RWAs are unaffected by this security incident. Bridge nodes have been temporarily disabled, so no new transactions can be submitted to the network. Effectively, the Liquid sidechain is paused until this issue is resolved. Liquid wallets will be impacted, and we're sorry for any inconvenience. Federation members are actively working on resolving this so we can restore normal network activity. You can monitor the situation via @mempool's liquid.network site below: mempool.space/address/bc1qdl…

Great to see @Blockstream Research point to Falcon-1024 as its preferred lattice-based signature scheme for Bitcoin. Falcon was co-invented by our CSO @ChrisPeikert, and Algorand was the first major public blockchain to integrate it for post-quantum security. Native Falcon-1024 PQ accounts are already live on mainnet. We're early.

BREAKING: A whistleblower from the USPS is warning that Trump's changes to the mail-in voting system could delay or block thousands of ballots from reaching voters. Mail ballots are starting to go out to military voters. This is chaos with the intent to disenfranchise millions of Americans who vote by mail -- the majority of whom tend to vote for Democrats. apnews.com/article/midterm-e…

On the filter fork topic. I don't usually have time, but this morning listened to one of the twitter spaces from earlier in the week, with some well meaning relative bitcoin newcomers, that humanized them, and their concerns and thoughts for why they thought that made it logical to support 110. My feeling after listening, is if these are the people with #110 in their handles, I'm sad to see them about to fork off and get disillusioned without understanding why bitcoin rejected 110 robustly. So here's a more empathetic, constructive higher level version of explaining why not. I hope it's high-level and first-principles enough that everyone can follow. They seem to want to understand what makes people tick, and are suspicious of intent. So, if someone asked me why is Bitcoin important and what is it, I'd say my (personal) mission and hope for bitcoin is to build the cypherpunk future, that "Snow Crash" was a blueprint, and work backwards from there. Bitcoin I hope leads to fully free markets via bearer unseizable, hard mathematically dependable money. Not everyone is comfortable with that level of freedom, but that's my view. And at this point, I believe that surprisingly, even now many governments have come to understand and value bitcoin's gold-like mathematical assurance, a positive development. Others may have milder views than myself, but still like hard censorship resistant money. Because of motive suspicion, if it's not obvious: I hate spam with a passion, that's how I came to design hashcash while researching decentralized bearer money with others, and running nodes in privacy related cypherpunk p2p networks nearly three decades ago. People seem upset about the default op return policy change in bitcoin. I will just assert, there are extremely robust and simple reasons for bitcoin changing default relay policy, and most just didn't do their research, so don't know what those are, or maybe not technical enough to fully understand though there have been 1000s of posts trying to explain in various simplified ways. So that lack of understanding lends itself to shared build-up of false narratives. So here's my back-to-basics higher level explanation. The decentralization needed to create cypherpunk money has implications a: side effect of decentralization is that you can't impose your views on others. The very decentralization mechanism that helps that, is working against what BIP 110 wants, which at it's most basic is a quest to police other people. I understand supporters don't see their intent like that, but introspect deeper. You can modify your software, but not anyone else's. Another critical and incredibly robust technical bitcoin immune system is bitcoin can't have people who don't understand technology basics insist on eroding security, decentralization robustness and core properties. That would end badly, fast, and so people will fight you on that. So the message is Bitcoin respectfully says "no" to what you want. Sorry, and bitcoiners do genuinely understand and empathize that you mean well, have high level thoughts that make emotional sense, and articulate sensible bitcoin-defensive high level ideas, but they are not grounded and without you seeing it, the way you propose to achieve your ideas, hard-conflict with free cypherpunk permissionless money. My advice is to listen to more experienced people who understand the system and why it works the way it does, to whatever detail you want to understand the grounded reasons for why this is the implication of decentralization and cypherpunk money. I guarantee you the developer and protocol ecosystem shares and exceeds your views on bearer hard money (and dislike of spam). You may not agree with individual developers choices, views, way of expressing themselves etc, BUT you also need to understand the IETF-like decentralized technical consensus process creates a protective change resistance, that is highly effective at protecting bitcoin mission. The implication of which is no developer can change anything without technical consensus from hundreds of other developers and protocol observers who are pedantic and extremely knowledgeable clever people who won't let any unaddressed technical question past. The protective change resistance is robust and decentralized in an amplifying way because of this technical consensus. And the many highly technical mainline developers' cypherpunk mission mindsets are probably far more determined than you can even handle on clarity of understanding and views about freedoms on permissionless networks, as many of you are probably still subconsciously inured by the matrix, where they have transcended that, and grew up immersed in it decades ago. They think natively in this space, while you are just grappling with the surface. Many wont have internalized or have the experience to know how this internet physics works, where there is no policeman, no policy authority, just mathematics, free market and hard money. That has implications for your views also, unfortunately. Now the tough pill, which is unfortunately true: If you won't listen to reason, educate yourself, learn, the same radical freedom applies to you: your permissionless recourse is to club together and create a fork. But bitcoin won't be joining it. (With respect and no sleight intended.) Please rejoin bitcoin now, or later if you're not convinced and need to experience 110 forking off and fizzling for yourself to start that journey of introspecting and learning. It would be sad if bitcoin lost people disillusioned due to simple lack of understanding of what's going on there, we're all trying to defend bitcoin and keep it on mission. Including btw the 110 technical promoters, just they wandered off plot somehow. Join the cypherpunks on bitcoin, come cypherpunk summer🌞 in a few weeks.
