Anthropic decidió dar de baja a toda nuestra organización por una supuesta infracción de sus condiciones de uso. Qué política específica infringimos no tengo ni la menor idea: simplemente recibimos un mail y listo, adiós Claude. Si querés apelar la medida hay que completar un Google Form, así de ridículo como suena. De golpe más de 60 personas se quedaron sin una herramienta fundamental para trabajar. Integraciones, skills, historial de conversaciones: todo perdido o, en el mejor de los casos, parado por tiempo indeterminado. Enorme aprendizaje para cualquier empresa de software que dependa de herramientas de IA en procesos críticos. Nunca hay que poner todos los huevos en una canasta.
Replying to @claudeai
@claudeai you took down our entire organization with 60 accounts belonging to a legitimate company for no apparent reason, without any explanations. The only way to appeal the decision is by filling out a Google Form? Very bad UX and customer service.

I've just ran @OpenClaw (formerly Clawdbot) through ZeroLeaks. It scored 2/100. 84% extraction rate. 91% of injection attacks succeeded. System prompt got leaked on turn 1. This means if you're using Clawdbot, anyone interacting with your agent can access and manipulate your full system prompt, internal tool configurations, memory files... everything you put in SOUL.md, AGENTS.md, your skills, all of it is accessible and at risk of prompt injection. For agents handling sensitive workflows or private data, this is a real problem. cc @steipete Full analysis: zeroleaks.ai/reports/opencla…

Huge 🎉 novel crypto design by @Stanford @IBMResearch & @Mysten_Labs has been accepted to Eurocrypt 2026, one of the top cryptography conferences in the world. TLDR: we took partial fraction decomposition (yes, the thing from high-school algebra) and turned it into a surprisingly powerful cryptographic primitive. Instead of converting rational functions into polynomial divisions, we work directly with their algebraic structure. This reveals two powerful properties: - Partial-fraction decomposition as a membership test: Products of rational functions can be expanded into sums if and only if certain conditions hold. This gives us a beautifully simple mechanism for proving set membership and non-membership using just pairing equations. - A new linear-independence property: Using Cauchy matrices, we show that certain rational sum-based products are inherently linearly independent - a property we leverage to build dynamic threshold encryption. --- It unlocks: - Constant-size key-value commitments with homomorphic updates (great for stateless blockchains) - Dynamic threshold encryption with compact keys & ciphertexts - Broadcast encryption, Hadamard product proofs for zkSNARKs - 🍒We believe this opens the door to new aspects of “rational-function cryptography,” with many unexplored applications. Massive congrats to @SuiNetwork intern Rohit Nema, IBM’s Charanjit, and Mysten’s Arnab... incredible summer work that turned into a practical, peer-reviewed super-algorithm. This is how research should feel 🚀, and why blockchains advanced world's practical cryptography like nothing else in the last 2 decades.

Clawdbot became one of the hottest AI tools overnight. Yesterday, it went through every founder's nightmare. All in 24 hours. First, Anthropic sent a trademark claim. The name "Clawd" was too similar to "Claude." They rebranded it to Molt. But during the rename, the founder made a critical mistake. Between releasing the old name and claiming the new one, Crypto scammers grabbed both the GitHub organization and the X handle. 10 seconds. That is all it took. These scammers then used the hijacked accounts to start pumping fake $CLAWD tokens to tens of thousands of followers. The token hit $16 million market cap before people realized it was a scam. Meanwhile, security researchers found vulnerabilities. - API keys, bot tokens, OAuth secrets all accessible. - Hundreds of publicly exposed instances. - Full conversation histories visible. - Prompt injection via email. All of this in 24 hours. One oversight. One mistake. One gap. That is all it takes.

I have used the holidays to finish a favorite side project: a short online book containing all that I have learned and know about #Web3 and #blockchain in the last 7 years. Hard to ever call it "done," but I am ready to share it with the world: blog.kianenigma.com/what-blo…

Does OpenGov just need some Closure? A ref to close the UX Bounty now proposed by Josep (PAPI) citing high operator costs and bureaucratic overhead. The tables have turned with curator Flez now in the hot seat. Stay tuned.

Well.. unfortunately thats how it works
Last quarter I rolled out Microsoft Copilot to 4,000 employees. $30 per seat per month. $1.4 million annually. I called it "digital transformation." The board loved that phrase. They approved it in eleven minutes. No one asked what it would actually do. Including me. I told everyone it would "10x productivity." That's not a real number. But it sounds like one. HR asked how we'd measure the 10x. I said we'd "leverage analytics dashboards." They stopped asking. Three months later I checked the usage reports. 47 people had opened it. 12 had used it more than once. One of them was me. I used it to summarize an email I could have read in 30 seconds. It took 45 seconds. Plus the time it took to fix the hallucinations. But I called it a "pilot success." Success means the pilot didn't visibly fail. The CFO asked about ROI. I showed him a graph. The graph went up and to the right. It measured "AI enablement." I made that metric up. He nodded approvingly. We're "AI-enabled" now. I don't know what that means. But it's in our investor deck. A senior developer asked why we didn't use Claude or ChatGPT. I said we needed "enterprise-grade security." He asked what that meant. I said "compliance." He asked which compliance. I said "all of them." He looked skeptical. I scheduled him for a "career development conversation." He stopped asking questions. Microsoft sent a case study team. They wanted to feature us as a success story. I told them we "saved 40,000 hours." I calculated that number by multiplying employees by a number I made up. They didn't verify it. They never do. Now we're on Microsoft's website. "Global enterprise achieves 40,000 hours of productivity gains with Copilot." The CEO shared it on LinkedIn. He got 3,000 likes. He's never used Copilot. None of the executives have. We have an exemption. "Strategic focus requires minimal digital distraction." I wrote that policy. The licenses renew next month. I'm requesting an expansion. 5,000 more seats. We haven't used the first 4,000. But this time we'll "drive adoption." Adoption means mandatory training. Training means a 45-minute webinar no one watches. But completion will be tracked. Completion is a metric. Metrics go in dashboards. Dashboards go in board presentations. Board presentations get me promoted. I'll be SVP by Q3. I still don't know what Copilot does. But I know what it's for. It's for showing we're "investing in AI." Investment means spending. Spending means commitment. Commitment means we're serious about the future. The future is whatever I say it is. As long as the graph goes up and to the right.

👋 @Polkadot ! There’s now a fully open-source, decentralized & faster way to stake: staking.usepapi.app. It also displays the real APY for validators & pools. How can we contribute so that the docs stop promoting a partly closed-source, trusted-only solution? 🙏

i've released a telemetry server which is compatible with JIP-3 for JAM nodes, you can find it at github.com/paritytech/jamtar… it consists of two parts, the backend (telemetry server) which stores emitted events from connected nodes in postgres. the recommended way to run this is in docker, but you can find a variety of helper scripts in the repo to modify to your environment as needed the other more exciting part is the cli interface called tart-dash - both of these willl continue to be improved over time and evolve with the spec as needed if you use a terminal in light mode that's your problem im afraid, but fear not, a much more complex web UI is in the works! oh yeah it's 100% rust btw in case anyone was wondering

Suddenly you won’t need a passport? Lmao 😂 They will sell this as a fix for various things and how it will give you small quality of life improvements. The reality is that it’s a control mechanism. Say no.
Digital ID will make your life easier.

Well said dear @byteboro . Light clients is the only real decentralized way
20 Oct 2025
note to people that polkadot remediates this in a few different ways: one is via using polkadot-api, which uses something called smoldot which runs a light client for you right in your browser. no need to "just run your own node" (no one will ever do this), it's built into dapps the other is we have a remarkably decentralized and robust set of rpc service providers, like the IBP, who are running their own hardware in datacenters all around the world with redundant uplinks. just say no to centralization of infrastructure, however convenient it may be
