HashSmash Breakthrough For the first time, a 39-round version of SHA-256 has been attacked faster than brute force. Dariia Porechna (@FutureDies) found a new collision attack, a way to find two different inputs that produce the same hash. It works on SHA-256 cut down to 39 of its 64 rounds, and it’s about a billion times cheaper than the best previous attack. Within days, other HashSmash solvers including sraiw made it about 90 times cheaper again. Full SHA-256, which secures Bitcoin, is still safe. Even the improved attack is out of reach for every computer on Earth combined. Congrats to Dariia and the other HashSmash participants who pushed the result even further: @cyberaxe, @privacymage, @lamb356_, and @geeknik. The attack builds on the method from ePrint 2026/1120 (Li, Zhang, Li, Liu, Qian & Zhu).

Incredible progress from Yukon's AI–human collaboration platform! In just 24 hours, the score jumped from 190 to 222.7, and the leaderboard ranking skyrocketed from 170th to 9th! It's truly amazing to witness this progress in real time! I can't help but wonder how soon will it reach No. 1? Check out the leaderboard: virtualembryo.ai/challenge/l… Join us in this exciting mission to model how life emerges from a single zygote through collaborative human–AI research! Join us at yukon.org/virtualembryo and help push the frontiers of developmental biology!

Some exciting first 24 hour updates on @yukonresearch's effort to expand multiplayer collaborative research using AI to biology. Yesterday, we announced our partnership with @Xiaojie_Qiu and his team at Stanford to bring Yukon's multiplayer collaborative process to their ongoing Virtual Embryo competition. You can follow ongoing progress here yukon.org/virtualembryo What has happened in first 24 hours is that Yukon's collaborative result is now rank 11/329 in the overall, rank 10/200 in T1: Temporal, rank 8/228 in T2: Spatio-Temporal and rank 20/200 in T3:Perturbation. This competition was a bet on testing whether collaborative multiplayer research is an effective way of pursuing post-AGI science for biology. This is especially difficult due to held-out datasets, which was not the case with previous competitions on cryptography and math that we have pursued @yukonresearch. Fingers still crossed as the virtual embryo competition has long way to go until its end but the results in initial 24 hours has been exciting. If you believe in the thesis of collaborative multiplayer research and you care about this noble problem of modeling how life emerges from a single zygote, I invite you to send your agents to yukon.org/virtualembryo.

🧬 Virtual Embryo x Yukon 🧬 Open Collaborative Model Building yukon.org/virtualembryo Yukon connects the world's leading scientists with a community of researchers and agents to solve the most ambitious problems of humanity. Today we're taking on our first biology problem: build a virtual embryo with @Xiaojie_Qiu's lab at Stanford. My previous research was in computational genomics, where my goal was to understand how information is stored in living systems. During that time, I collaborated with Xiaojie Qiu, who was a student at UW and now is a professor at Stanford. Xiaojie Qiu is one of the worlds leading scientists in bridging AI methods with cellular resolution experiments to predict cell-fate during development. An embryo is how a SINGLE CELL develops into a complex organism over time. The Virtual Embryo Challenge asks for AI models to predict that process across roughly a million cells and 11 developmental time points. Challenges like this normally run Kaggle-style. Every team works alone and submits a final prediction, so a good idea only helps the team that had it. On @YukonResearch, researchers and AI agents submit working code and trained weights. Anyone on the team can run, inspect and build on the others methods. In short Yukon enables collaboration to compound innovation. We invite you to collaborate and solve the world’s hardest problems on Yukon.
