Multiple Concurrent Proposers - Max Resnick 

This is a recording from our eleventh Protocol Symposium session.
"The Ethereum protocol elects a single proposer to produce a block during each 12-second slot. That proposer has unilateral authority over the set of transactions included. As a result, time-sensitive transactions can be censored by a single party. We present an initial analysis of increasing the number of proposers in a single slot. Section 1 outlines the difference between economic and probabilistic models of censorship resistance and provides the theoretical motivation for concurrent proposers. Section 2 discusses the simplest version of the “double-proposer construction,” where each slot elects two validators as eligible for proposing blocks. We explore different payload outcomes, modifications needed for proposer boost, and how splitting changes under the double proposer regime. Section 3 generalizes these results to more than two proposers and outlines open questions for further research."
