About
I am currently the Head of Research at ChainCode Labs, where I lead research initiatives in blockchain technology and cryptoeconomics. Previously, I was at the Simons Institute for the Theory of Computing at Berkeley and at CalTech.
I graduated from Tel Aviv University with a PhD in Mathematics under the supervision of Prof. Noga Alon. My thesis was titled 'Generalized Turán Type Problems and other Questions'. I completed my master's degree at the Weizmann Institute under Prof. Ehud Friedgut, with a thesis titled Thresholds of monotone properties with small minterms.

What Happens to Bitcoin When Quantum Computers Arrive?
A high-level overview of the recent report by Chaincode Labs on the threat quantum computing poses to Bitcoin. Co-authored with Anthony Milton, this article explores timelines, threat models, and migration strategies for quantum-resistant cryptography.

A contingency framework for Bitcoin's response to Cryptographically Relevant Quantum Computers (CRQCs). This playbook outlines implementation requirements, three-team coordination structure, and a timeline for achieving quantum resistance while maintaining network continuity.
