Claim: gpt-5-pro can prove new interesting mathematics. Proof: I took a convex optimization paper with a clean open problem in it and asked gpt-5-pro to work on it. It proved a better bound than what is in the paper, and I checked the proof it's correct. Details below.

Learn about KZH-fold: a new accumulation/folding scheme! 2000x reduction in communication and 50x faster decider time compared to Nova for 2000 Poseidon hashes, at a cost of 3x the prover time. Hossein Hafezi presented this standout collab from the Ethereum Foundation & NYU!…

Recently, I presented our recent work, "KZH-Fold: Accountable Voting from Sublinear Accumulation" (joint work with @benediktbuenz @arantxazapico and @asn_d6) at Stanford Security Seminar, you may find the video here: crypto.stanford.edu/seclab/sem-24-…

Accumulation/Folding schemes are all the hype. However, all current schemes have proofs that are linear in the circuit size (think megabytes). That might be ok if you are locally proving (IVC) but doesn't scale for distributed proving (PCD). Cue KZH-fold: eprint.iacr.org/2025/144

I wish to see it in the academia too. Scholarships given to a specific race or gender is the most stupid thing ever! Make it merit-based.

I sent a Happy New Year message to an old high school friend, and learnt he'd been in an accident months ago and has no feeling from the chest down. I truly hope he recovers and gets back on his feet. It was a reminder of how blessed we are with health, often not realizing it.
