WARNING! Account Khovr_ (with underscore) is impersonating me. Don't get tricked, i know there were PMs.

🎙️ Speaker Announcement! 🎉 Join us at the #DeFiSecuritySummit to hear Dmitry Khovratovich of Ethereum and ABDK talk about “Zero Knowledge Security in DeFi and elsewhere” Stay tuned for more updates on our lineup! 🌟 🌐 More info: defisecuritysummit.org

On Sunday 10.20 AM at Defi Security Summit Dmitry will talk about unusual bugs that arise when coding DeFi apps in circuits for Rollups and ZK proofs Catch it here: youtube.com/watch?v=vCfeff…

What do you know about zero knowledge security, in DeFi and elsewhere? Follow Dmitry Khovratovich of ABDK live youtube.com/watch?v=vCfeff…

Uniswap Labs 🦄 Little piece of trivia: Mikhail from ABDK wrote the tick math library for Uniswap V3 and the derivation was made public here hackmd.io/odBcee5CRpqzmt…

Why all the IACR "paper submission" websites are all on the same domain, but the login/passwords can't be reused? This creates a total mess all the time. Who designed that? Why not using 3d/4th level domain name for every new conference? #iacr

Hashing it out at #QSig The University of Edinburgh - Dmitry Khovratovich Ethereum Input Output @ Rare Evo Cardano Foundation The University of Edinburgh

Ethereum Foundation boosts the third-party cryptanalysis of Poseidon hash. It provides bounties for breaking small versions, awards for new attacks, and short-term grants to fill the gaps the existing analysis. Total Fund: $500 000 poseidon-initiative.info #Ethereum

We have recently audited a #cryptographic protocol devoted to proof aggregation for NEBRA We have found several major issues, including a dangerous forgery attack. A full math description of the attack and the details of other issues are by the link bit.ly/4eTuVHI

This is Ethereum Foundation (joint work with TU/e) first attempt to design hash-based signatures tailored to SNARK aggregation! We seek new implementations, and we would love to collaborate with Explore Expander bootcamp participants. Come build with us. eprint.iacr.org/2025/055.pdf

coming soon: there is an invisible line in circuit complexity. nobody knows exactly where it is! cross it - and everything will go down in flames and beware of quines, they want to hurt you (upcoming work with Ron Ron Rothblum and Dmitry Dmitry Khovratovich )

1/ Excited, but frankly quite worried, about a new work with the wonderful 🏴 levochka.eth 🏴 💙💛🇮🇱☀️🦁🗡️ and Dmitry Khovratovich: ia.cr/2025/118 We break soundness of a standard protocol (essentially commit to witness and run GKR) by constructing a circuit for which we can prove a false statement.

The deadline for Short Term #Poseidon Grants has been extended to 15th March 2025 poseidon-initiative.info/#h.igyegrb8v5vn All researchers from the academia #iacr and the industry are welcome to apply!
