📣Excited to announce that I will start as an Assistant Professor @PurdueCS in Fall 2026! I plan to recruit multiple PhD students for a broad range of cryptography and blockchain topics. More details soon. For the next year, I'll be a postdoc at Columbia with @Tim_Roughgarden.

Should short conference papers be for: (A) Standalone short but useful results (B) Preliminary results in a larger work Is it a hot take to say they should be (A) and that we should have non-archival workshops for (B)?

See our paper for more details! Lots of interesting open questions remain. Joint work w/ Aadityan Ganesh, @AditiPartap97, @josephbonneau, and Matt Weinberg 6/6

Still, there's a useful positive result We construct a whistleblowing protocol that takes a small deposit from everyone and can protect even against "smart colluders" with roughly t times as much capital We also prove a lower bound to show that this is roughly optimal 5/

We prove an impossibility for whistleblowing if corrupt parties coordinate in a new way---through smart contracts! Intuition is they can enforce mafia-like retaliation if anyone defects Result holds even when whistleblowing is anonymous and can identify all corrupt parties 4/

A nice idea from prior work is to enable corrupt parties to whistleblow or snitch against their co-conspirators Our work defines a broad framework for whistleblowing protocols We analyze both when whistleblowing proofs are feasible and how to incentivize their submission 3/

Many crypto protocols require for security that e.g., "less than t-out-of-n nodes are corrupt" Think secret sharing, threshold decryption, randomness beacons etc While we'd like the protocol itself to detect when such honesty assumptions fail, this is commonly impossible 2/

I will present new work @acm_ccs this week Breaking Omertà: On Threshold Cryptography, Smart Collusion, and Whistleblowing https://t.co/O0SGFwIV5j tldr; preventing collusion in crypto protocols is hard and even more so when smart contracts are used to facilitate collusion. 1/🧵

Highly recommended! Direct quote from my thesis: "Discussions during my stay at a16z crypto were a significant inspiration for the research vision in this dissertation."

In the spirit of a PhD being a "philosophy" degree, the intro and closing remarks of the dissertation reflect my personal philosophy on why blockchain security is so radically different and so important to study.

My PhD dissertation is now available online! ( https://t.co/96Xt7xtZWV) Title: Rethinking Security for Emerging Decentralized Systems Extremely fortunate to have had @AriJuels as my PhD advisor at Cornell Tech.

New research center focused on blockchain infrastructure @CUSEAS ! Made possible by @ethereumfndn. Super-excited about this, more to come!

On August 13, IC3 and the Columbia Ethereum Research Center will co-host the Ethereum Research Funding Forum - a day focused on research priorities in Ethereum.

Join us for the Lagrange Science Fair this Thursday, July 31st in anticipation of SBC 2025 (Science of Blockchain Conference)! Hear from top researchers from @Yale, @Stanford, @Cornell, @UCBerkeley, and @Penn on new innovations in blockchain & AI: https://t.co/q2CbOUku7E

The Agenda for MEV-SBC'25 is live! 📍Aug 7 @ Berkeley This annual workshop highlights MEV research and talks to illuminate a new round of problems for the community to explore in cryptography, mechanism design, data, consensus, incentives, and their intersections

"Defunding NSF means defunding scientists in the U.S. - including those leading crypto innovation." In a new @CoinDesk op-ed, leading American researchers @danboneh, @josephbonneau, @giuliacfanti, @benafisch, @AriJuels, @socrates1024, @FKoushanfar, @dntse, @ciamac, and

Take My Ape is out! Try it at https://t.co/lzVTi2tHc2. Own a Bored Ape for 15 minutes with one Ethereum transaction. Ownership ≠ rental. It means copyright license, access to BAYC spaces, and your address on chain as owner. TMA's goal? To demo the power of Liquefaction.

NEW: IC3 researchers present Liquefaction — a wallet platform that redefines private key control in crypto. Liquefaction allows private key access to be shared, rented, or pooled, supporting multi-user policies around crypto assets without direct on-chain traces. Trusted

Prof. @ittayeyal, @mskd96, and @_mahimna also evaluate other authentication mechanisms and propose solutions to enhance security, including for India’s largest bank.
