Performance of Raspberry Pi during Blockchain Execution using Proof of Authority Consensus

Raspberry Pi is one of the most popular devices for research in many different fields. It is proposed to analyse its performance as a lightweight blockchain node. This could enable the Raspberry Pi to execute other tasks and the same time, like data acquisition or working as an Internet of Things node, without losing performance. To achieve this, a specific consensus protocol is used to light the processing load. This testbed is evaluated in several benchmarks, whose results clarify the limits of this device as a lightweight blockchain node.
