I wrote four cryptography challenges for DiceCTF 2025 Quals this year! There's some stuff on ring signatures, garbled circuits, and oblivious transfer. You can read my writeups here: priv.pub/posts/dicectf-…

🪄✨ And for our next trick, choose a code, any code! Introducing WARP 🌀, the first linear-time accumulation scheme. Brought to you by Benedikt Bünz ☕️, Alessandro Chiesa, William and myself. 📚: ia.cr/2025/753 🧑‍💻: (soon)

Learn about WARP from William at zkSummit - the first accumulation scheme achieving linear prover time with logarithmic verifier complexity. Built on hash-based cryptography and supporting unbounded accumulation depth, they a new notion of straightline round-by-round

Excited to announce our collaboration with DiceGang to host an epic battle for hackers of all ages. This will be the inaugural event for QuendCon. See you in Brooklyn…. Stay tuned for more
