ZisK v1.3.0-alpha release 🚀 ZisK is moving beyond arithmetic hashes with BLAKE3 strengthening security while outperforming our prior Poseidon1 version: ⚡ 7.43s p999 on 4×5090 ⚡ 5.14s p999 on 8×5090 🛡️ 128-bit provable security 🔐 Post-quantum secure This is a major step toward faster and safer proving. Release notes: github.com/0xPolygonHermez/z…

Verify a credential without calling the issuer. Propia is a public registry of issuer authority, keys and status. Any verifier can read it, and no personal data goes on it. Built with @class_lambda and @alignedlayer. propia.id/whitepaper

Let’s make identity reusable across the city. Grateful to Bogotá for the trust. The SuperApp will give citizens verifiable credentials they control, not another silo. That stack is Propia + SovraWallet, built with @class_lambda and @alignedlayer. An open protocol, @ethereum secured, and a wallet that stays with the person. Thank you @Bogota @ConsejeriaTIC

The state of Nuevo León, the richest in Mexico, is using @ethrex_client and the @alignedlayer white label solution wallet. Every important government procedure is being built on top of our stack, and millions of procedures every year will be powered by it, all secured with ZK and Ethereum. Congrats @sovraio and @class_lambda. Technology developed by the Ethereum ecosystem becoming infrastructure that millions of people can rely on in their everyday lives. Most citizens may never need to know what runs underneath, but they will benefit from systems that are more secure, transparent, efficient, and verifiable. For the last two years, I’ve been saying that we’re developing multiple solutions that use the technologies Ethereum pioneered to make states more powerful and citizens more free. We're working with multiple strategic partners around the world. Ethereum is not only building a new financial system, it is giving us the tools to build better institutions and better public infrastructure. This is only the beginning. We’ll be sharing much more in the months to come. And a special congrats to @fernandezdiego, our CEO in Sovra, for all the hard work that helped make this possible. We are closing more and more big deals, Diego is a deal making machine. I've learnt so much from you, I'm proud of marching under your command.

I want to congratulate @WillyDuran65 on his new term as dean of the Faculty of Exact and Natural Sciences of the University of Buenos Aires. Willy thanked Francisco Strambini and me, and he also thanked @class_lambda for its contributions and its relationship with the university. I value that a lot. Most people on X have a somewhat wrong image of what Lambda is. Many believe we’re a devshop that works in crypto, when we have dozens of successful products in different industries and most of our core members are mathematicians, physicists, mechanical engineers, chemical engineers, civil engineers and industrial engineers and yes obviously computer scientists and computer engineers. Lambda is and has always been deep tech. If you want to build SaaS (something that we also do), you don’t need to understand what a Koopman operator is, finite element method or what Riemann zeta function is. But if you want to build companies at the frontier of science and engineering, you need people who understand things deeply and can work on hard problems. That’s why Lambda’s relationship with the University of Buenos Aires, with the Faculty of Engineering and particularly with the Faculty of Exact and Natural Sciences is so important and strategic. For me, the relationship with the university has always been strange and very personal. I’m a college dropout who, more than 15 years later, came back to reform the same degree program I had dropped out of. It’s a strange circle. I left the university without a degree, but part of the university is still shaping the way I think. I spent more than 20 years in the private sector learning how to build companies, products and technology. Now I’m using everything I learned to build a new degree program at the University of Buenos Aires. I want to create an elite of builders who want to innovate. Not an elite based on money, family or status. An elite based on knowledge, work and the ability to turn science and engineering into companies and good public policies. For me, this is not about proving that I never needed the university. It’s the opposite, it’s about giving back, closing a circle and helping create the education that I believe the next generation of builders needs. If we want to create a better world, we need to create companies that are at the frontier of science and engineering and that work with universities and the public sector. We also need to destroy this idea, that part of the left has, that companies go to public universities only to steal their knowledge or to destroy them. Real deep tech companies need strong universities. A deep-tech company has nothing to gain from a weak university. But this works both ways. Universities also need a big and capable private sector with the ability to innovate, turn knowledge into products and give back to the universities that made that innovation possible. Universities have the right environment to do research that is long term and doesn’t depend on the results of the next quarter. This is something that part of the right in Argentina doesn't understand. Companies need the public universtiy that is the one creating the most amount of professionals for our country and doing the best international research. The University needs money to be able to give freedom to researchers to work on difficult problems. Then companies have the ability to turn that research and knowledge into products, jobs and new industries. They have different roles, but they need each other. This shouldn't be an ideological debate but a practical one. Willy and I have our differences, as all good friend have, but we also have a very strong bond. We believe in science. We believe the state should invest in it. We believe this is better for the country, for universities and for companies. It’s a win-win. That’s why I value my relationship with Willy so highly. Even with our differences, we agree on what we want. Thanks Willy and I hope you keep doing an amazing job.

tl;dr: we present an interpolation attack on 28 out of 31 rounds of Poseidon in practical time via a novel technique for partial round skipping; see ia.cr/2026/1692. 🧵⬇

Over the past months, Sovra, @class_lambda and @alignedlayer have been working together on Propia, a public protocol for verifiable digital credentials. Propia starts from a simple premise: trust established by one institution should be reusable by others, without requiring shared databases or dependence on a private intermediary. This has become increasingly relevant as AI agents begin to participate in everyday operations. They submit requests, exchange information, authorize transactions and interact with other agents. These interactions need a reliable way to establish who an agent represents, what it is authorized to do and whether the claims it presents remain valid. Rebuilding that verification process within every organization is costly and creates isolated systems. A shared protocol allows credentials to be issued once and independently verified wherever they are needed, including by machines acting on someone’s behalf. For institutions, this means fewer repeated checks, fewer custom integrations and lower operating costs. As more institutions participate, more credentials can be reused and the protocol becomes more useful for everyone. We believe this infrastructure should be open and collectively governed. Today, we are publishing the whitepaper as a public proposal and inviting others to discuss it, improve it and build on it.

Sir @TomerAshur from @3miLabs was right! I'm proud of working with Tomer and his amazing team. Smart people that fight for what they believe.
