Abstract

With the spread of the Internet of Things, many devices are being connected, collecting and transmitting data. Blockchain is a secure solution for distributed ledgers, but its high computational and energy costs are limiting for devices with limited resources. In this study, we modified Blockbench to evaluate the performance of Ethereum private networks involving a Raspberry Pi. Scenarios with and without the device and the consensus protocols Ethash and Clique were compared. The results show that the Raspberry Pi cannot be a miner in the Ethash network, but only a lightweight node, and emphasize the superiority of the Clique consensus regarding latency, throughput, and consumption of computing resources.
