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.
