Consensus protocols -- distributed protocols for agreeing on the state of a system in the presence of corruptions and network failures -- are at the core of distributed computing and also provide a foundational building protocol for multi-party cryptographic protocols. The emergence of Bitcoin, and its associated blockchain protocol, has led to an urgent need from the public and industry for new types of consensus protocols that scale to a large number of participants, deal with ever-changing participants, and for some applications (such as Bitcoin) operate in a fully "permissionless" setting (anyone can arbitrarily join and leave the computation).

This workshop will focus on the theoretical foundations of these new desiderata. The main sub-themes are: the theoretical analysis of existing protocols (such as Bitcoin's blockchain protocol) or alternative protocols; the formulation of security goals; the study of game-theoretic challenges that are new to this setting; and the development of practical protocols that address an increasing demand from the public and industry.

Further details about this workshop will be posted in due course. Enquiries may be sent to the organizers workshop-proofs2 [at] lists [dot] simons [dot] berkeley [dot] edu (at this address).

All events take place in the Calvin Lab auditorium.
