Query: Permissioned Blockchain Through the Looking Glass: Architectural and
  Implementation Lessons Learned   Since the inception of Bitcoin, the distributed systems community has shown
interest in the design of efficient blockchain systems. However, initial
blockchain applications (like Bitcoin) attain very low throughput, which has
promoted the design of permissioned blockchain systems. These permissioned
blockchain systems employ classical Byzantine-Fault Tolerant (BFT) protocols to
reach consensus. However, existing permissioned blockchain systems still attain
low throughputs (of the order 10K txns/s). As a result, existing works blame
this low throughput on the associated BFT protocol and expend resources in
developing optimized protocols. We believe such blames only depict a one-sided
story. In specific, we raise a simple question: can a well-crafted system based
on a classical BFT protocol outperform a modern protocol? We show that
designing such a well-crafted system is possible and illustrate that even if
such a system employs a three-phase protocol, it can outperform another system
utilizing a single-phase protocol. This endeavor requires us to dissect a
permissioned blockchain system and highlight different factors that affect its
performance. Based on our insights, we present the design of our
enterprise-grade, high-throughput yielding permissioned blockchain system,
ResilientDB, that employs multi-threaded deep pipelines, to balance tasks at a
replica, and provides guidelines for future designs.
