  Quorum is a permissioned blockchain platform built from the Ethereum codebase
with adaptations to make it a permissioned consortium platform. It is one of
the key contenders in the permissioned ledger space. Quorum supports
confidentiality and privacy of smart contracts and transactions, and crash and
Byzantine fault tolerant consensus algorithms. In this paper, we characterize
the performance features of Quorum. We study the throughput and latency
characteristics of Quorum with different workloads and consensus algorithms
that it supports. Through a suite of micro-benchmarks, we explore how certain
transaction and smart contract parameters can affect transaction latencies.
