So it appears that Pavel Durov has been using cryptography without a license.

Transparency in blockchains is a bug, not a feature.

Surprise!

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.

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.

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

Recently, I presented our recent work, "KZH-Fold: Accountable Voting from Sublinear Accumulation" (joint work with Benedikt Bünz ☕️ Arantxa Zapico 🧉 and George Kadianakis) at Stanford Security Seminar, you may find the video here: crypto.stanford.edu/seclab/sem-24-…

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!

We are recruiting.
