Dear friends, Thursday at 11:00 in D0.03 we'll welcome another guest speaker, Chen-Da Liu-Zhang, who will give a talk on distributed cryptography. Title and abstract below. Best regards, Will Schober Speaker: Chen-Da Liu-Zhang Title: Distributed Cryptography with Dynamic Committees Abstract: Protocols with dynamic committees have emerged over the past decade to enable scalable distributed computation while remaining secure against adaptive denial-of-service (DoS) attacks, with Bitcoin and Algorand among the most notable examples. This talk will cover recent advances in distributed cryptography with dynamic committees, including a unified framework for designing such protocols and new approaches to consensus and secure computation in this setting. The presentation will draw on results from recent papers published at PODC 2021, Eurocrypt 2022 and 2025, Crypto 2023, TCC 2024 and Financial Cryptography 2024.
