SUMMARY:Canopus: Scalable Consensus for Permissioned Blockchains
DESCRIPTION:A critical problem with the consensus protocols underlying
 blockchains is that they do not scale well. As the number of participants
 trying to achieve consensus increases\, increasing network traffic from
 topology-oblivious broadcasts can quickly overwhelm the network\, or\, when
 using centralized consensus protocols\, overwhelm the central coordinator.
 Thus\, achieving strong consensus is typically restricted to a handful of
 participants\, or systems must resort to weaker forms of consensus\, such
 as those using proof of work. To address this problem\, we propose
 Canopus\, a highly-parallel consensus protocol that exploits modern data
 center network topology\, parallelism\, and consensus semantics to achieve
 scalability. Our key insight is to make network communication patterns
 topology-aware. In our prototype implementation\, Canopus achieves rates as
 high as 5m linearizable transactions/second over 27 nodes distributed
 across 7 datacenters. I will also discuss a recent extension\, Resilient
 Canopus\, that makes Canopus Byzantine Fault Tolerant.\n(Joint work with
