Conference paper Open Access
With ever more IoT (Internet of Things) and big
data applications, the emerging blockchain techniques provide
fundamental supports to credibly track the transactions of
digital assets. Public blockchains, e.g., bitcoin, are often energyconsuming
and low efficient. Therefore, an empirical study of
operating permissioned blockchains in clouds is urgently needed.
In this paper, we study the performance of Sawtooth, a wellknown
permissioned blockchain platforms from Hyperledger, in
cloud environments. Our results provide insights for blockchain
operators to optimize the performance of Sawtooth through
adjusting the two configuration parameters, i.e., Scheduler and
Maximum Batches Per Block. Our approach can be used to test
other blockchain platforms.
