Legendary to see Bark & Cashu independently seize Payjoin as settlement infrastructure. This gives the Payjoin primitive a whole new identity as the go-to tool for Transaction Cut-Through.
1/ Payjoin boards have been available in Bark for a couple of weeks now, so we thought it was time to take a closer look at what they can do: boarding direct from external wallet apps, saving the user fees and time, and the same trick applied to on-ramping into Cashu mints.

There seems to be a misunderstanding here. The message is not that you can't fork off. The community is telling you: * It's disinterested in your fork. * You can't have the Bitcoin brand. * It would have been appreciated if you weren't trying to make such a mess. Godspeed!

I have spent over $10,000 scanning 100+ bitcoin ecosystem related libraries looking for vulnerabilities with Kimi K3 running as quarterback. Myself and a small "Red Team" have found multiple serious vulnerabilities impacting the ecosystem. They vary in scope severity, but this is a call to action. For any critical tier vulnerability that was identified if I was able to immediately demonstrate a POC (proof of concept), I have already responsibly disclosed to the maintainers. HERE IS HOW YOU CAN HELP ME IF YOU ARE NOT TECHNICAL: - please share with me any repository that is on github that I can scan, we want to cast a wide net. It takes a few moments for you to link github accounts, we'll take it from there - if that project does not have a SECURITY.md make an issue asking the dev to list one IF YOU ARE TECHNICAL: - If you are a maintainer or contributor to a project, I may have already scanned your repo, hit me up I'll share the results, if not I'll add your project to the list. - If I can trust you to do larger review to start looking through this stuff to give me more eyes let me know. AI Has forever changed software development. Tomorrow marks 1 week of Kimi k3 being live in open weights. We are going to accelerate.

Really, the most embarrassing part for the ecosystem is how quickly some developers found the bug after the attacker’s first transactions appeared. We made “Don’t trust, verify” our favorite meme, yet we collectively assumed someone else had already done the verifying. Five years and no one noticed it.
I was thinking about this long before today’s incident. I even messaged @niftynei when she was organizing the Villains edition of btcpp. Today’s incident only reinforced my view: Bitcoiners trust far more than we like to admit. Bitcoiners often overestimate how much scrutiny critical software actually receives. Open source doesn’t automatically mean heavily audited. Popular doesn’t automatically mean well reviewed. Reputation isn’t a substitute for review.

Unless @Apple's decision to terminate @craigraw's Apple Developer account is reversed by June 30, all new installs of Sparrow will fail, and development on macOS will end. If you value Sparrow, a repost would help. @AppleSupport
My attempt to protect users from scam apps on the @AppStore has gotten my Apple Developer account flagged for termination - ironically, for "dishonest activity". Unless it's reversed by June 30, all new installs of Sparrow Wallet will fail, and development on macOS will end. The context: since 2023, more than a dozen fake "Sparrow" apps have appeared on the App Store, as recently as April this year. Users have contacted me after losing their savings, in some cases their life savings, to these impersonators. I'm the developer of the real Sparrow Wallet, a desktop app, and I hold the registered US trademarks for the name and logo. I have publicly warned @Apple and the community about these fake apps from early 2024, but they keep appearing. The app @Apple flagged was a placeholder that was never published. Its only purpose was to warn users that Sparrow is desktop-only and that other "Sparrow" apps aren't mine. This approach may have been misguided, but there was nothing dishonest about it. I'm confident this is an automated misclassification that Apple would reverse on review - but I may be terminated before a human ever looks at my appeal. The cost would fall on @Apple's own users: blocked installs and no updates for a tool people rely on, which opens the door for more fakes. If you value Sparrow, a repost would help. @AppleSupport

1/ Project Eleven just awarded 1 BTC for "the largest quantum attack on ECC to date", a 17-bit elliptic curve key recovered on IBM Quantum hardware. I replaced the quantum computer with /dev/urandom. It still recovers the key.

Judging by my tl there is a growing gap in understanding of AI capability. The first issue I think is around recency and tier of use. I think a lot of people tried the free tier of ChatGPT somewhere last year and allowed it to inform their views on AI a little too much. This is a group of reactions laughing at various quirks of the models, hallucinations, etc. Yes I also saw the viral videos of OpenAI's Advanced Voice mode fumbling simple queries like "should I drive or walk to the carwash". The thing is that these free and old/deprecated models don't reflect the capability in the latest round of state of the art agentic models of this year, especially OpenAI Codex and Claude Code. But that brings me to the second issue. Even if people paid $200/month to use the state of the art models, a lot of the capabilities are relatively "peaky" in highly technical areas. Typical queries around search, writing, advice, etc. are *not* the domain that has made the most noticeable and dramatic strides in capability. Partly, this is due to the technical details of reinforcement learning and its use of verifiable rewards. But partly, it's also because these use cases are not sufficiently prioritized by the companies in their hillclimbing because they don't lead to as much $$$ value. The goldmines are elsewhere, and the focus comes along. So that brings me to the second group of people, who *both* 1) pay for and use the state of the art frontier agentic models (OpenAI Codex / Claude Code) and 2) do so professionally in technical domains like programming, math and research. This group of people is subject to the highest amount of "AI Psychosis" because the recent improvements in these domains as of this year have been nothing short of staggering. When you hand a computer terminal to one of these models, you can now watch them melt programming problems that you'd normally expect to take days/weeks of work. It's this second group of people that assigns a much greater gravity to the capabilities, their slope, and various cyber-related repercussions. TLDR the people in these two groups are speaking past each other. It really is simultaneously the case that OpenAI's free and I think slightly orphaned (?) "Advanced Voice Mode" will fumble the dumbest questions in your Instagram's reels and *at the same time*, OpenAI's highest-tier and paid Codex model will go off for 1 hour to coherently restructure an entire code base, or find and exploit vulnerabilities in computer systems. This part really works and has made dramatic strides because 2 properties: 1) these domains offer explicit reward functions that are verifiable meaning they are easily amenable to reinforcement learning training (e.g. unit tests passed yes or no, in contrast to writing, which is much harder to explicitly judge), but also 2) they are a lot more valuable in b2b settings, meaning that the biggest fraction of the team is focused on improving them. So here we are.
The degree to which you are awed by AI is perfectly correlated with how much you use AI to code.

How can wallet fingerprints be used to damage Payjoin privacy? @Arminsdev spent a week in a darkly lit room to study this class of attacks against real-world Payjoins.

This is the bottom-of-the-barrel shitcoin @Jason is shilling after being an outspoken Bitcoin skeptic for over a decade
The uselessness of $TAO is truly spectacular $10 billion marketcap for an "AI coin" Go check it out—what does it actually do? It runs a bunch of different subnets. Okay? What are these subnets? Check out subnet #1. Okay, so text prompting. Cool. That's easy enough to understand. But what's actually going on there? Check the docs. github.com/opentensor/prompt… Okay, so miners on this subnet run 2 different LLMs. Zephyr and wiki-agent. Mostly they all just run Zephyr, the base model (now switching to one called Solar). The idea is super simple. You send in a prompt. The miners will run the LLM and respond to you, like ChatGPT. Miners who do this are rewarded with TAO tokens. This is how TAO tokens are brought into existence. But it does mean that for every prompt, you have literally a thousand miners who will complete the exact same task, redundantly. The network will then validate these answers by checking how similiar they are to eachother. If you're an outlier you don't get TAO tokens. So what's going on here is that a prompt will be generated, such as "What is water?" And the miners will respond with "Water is a chemical compound with the molecular formula H2O", and they're all incentivized run the same LLM because outlier responses are punished. This is repeated in parallel a thousand of times by a thousand different miners. There's no AI magic to validate whether a model was actually run. There's nothing that stops miners from copying replies from eachother and tweaking them, spoofing their work. The validation mechanism is super basic: In the present version, the validator produces one or more reference answers which all miner responses are compared to. Those which are most similar to the reference answer will attain the highest rewards and ultimately gain the most incentive. —github.com/opentensor/prompt… Setting aside how easy this is to spoof for a second, just think about the incomprehensible inefficiency of this system. For each prompt, you have 1000 miners doing the same work? So that you'll reach a level of "decentralized intelligence"? Look my dudes. Just put a single miner in Tanzania. Prompt it. If it gets shut down or outputs bad data, fall-over to a different one somewhere else. You don't need 1000 different redudant LLMs to run these basic bitch language models in parallel if you can't even protect against them copying and tweaking answers to fake their homework. And what even is the purpose of running these "decentralized" models? Zephyr, Solar and wiki-agent have the same kind of content filters that ChatGPT has. Zephyr is even trained on ChatGPT dialogue output. So you have 1000 miners serving you the same bottom-of-the-barrel answers 1000 less efficiently than its centralized counterparts, *still* with no ability to verify whether 1000 separate answers were even generated since the only thing you're doing is checking for similarity. Now, the crown jewel of this ridiculous piece of garbage is the fact that you can't even prompt this network as a regular user. Go on, try it. Go try to actually interface with this network as a user and get a Zephyr-generated response from 1000 miners. You can't. The only thing that is happening in this subnet is internal, validators generate challenge prompts and 1000 miners generate the same basic bitch LLM response and collect TAO tokens. These TAO tokens are then sold into a $10 billion FDV market cap of retail idiot buyers who are trying to get exposure to "decentralized AI" by buying this piece of shit AI memecoin. Bittensor is pretty much what a highschooler would think of if he was tasked with creating an AI coin. "Uhh I just have maybe 1000 miners generating answers to prompts, so it's like, uh, decentralized?" "Okay, and how do you check that? How do you do the verification?" "Uh, maybe the network can check, like, if the answers are similar or some shit?" This is a pointless exercise in decentralization that only serves the purpose of vaguely resembling doing something with "decentralized AI", which of course is a cool meme right now, but it doesn't actually provide you with any assurances, any utility, except a 1000x less efficient ChatGPT-bot that can only answer questions to itself so it has an excuse to print tokens to dump on the crypto retail market. Send it to fucking 0.
