Byzantine Consensus Over Broadcast Channels

Abstract

Abstract:

We study communication with consensus over a broadcast channel - the receivers reliably decode the sender’s message when the sender is honest, and their decoder outputs agree even if the sender acts maliciously. We characterize the broadcast channels which permit this byzantine consensus and determine their capacity.
