Dear all,
Next week, we have the pleasure of having Joachim Matthias Neu give a talk in the colloquium.
The seminar will be held on Monday, January 15th at 14:00. Location: C220.
The title, abstract and bio appear below.
Looking forward to seeing you, Sagie and Liat
*Title:* Internet-Scale Consensus in the Blockchain Era.
*Abstract:* Blockchains have ignited interest in Internet-scale consensus as a vital building block for decentralized applications and services that promise egalitarian access and robustness to faults and abuse. While the study of consensus has a 40+ year tradition, the new Internet-scale setting requires a fundamental rethinking of models, desiderata, and protocols. An emergent key challenge is to simultaneously serve clients with different requirements regarding the two fundamental aspects liveness ("good things happen") and safety ("bad things don't happen"). For different instances of this theme, I present the first protocols that allow optimal liveness-safety tradeoff. Results from this line of work have found adoption in the Ethereum blockchain that powers an ecosystem worth $500bn+.
*Bio*: Joachim Neu is a PhD candidate at Stanford University advised by David Tse. His research focuses on Internet-scale consensus as a key enabler for decentralized systems, and spans distributed systems, probabilistic systems analysis, applied cryptography, and networking/communications.
