Energy Benchmarks for the IOTA Network (Chrysalis Edition)

TL;DR

In our tests, a Raspberry Pi 4 node uses just over a millionth of a kWh per IOTA message/transaction, including proof-of-work costs.
For comparison, making one mug of coffee in a single-serve machine uses about .024 kWh (nearly 22,000 times as much energy).


Executive Summary

There is increasing, and appropriate, scrutiny of the energy footprint related to cryptocurrency networks. At the IOTA Foundation, we place emphasis on low energy requirements and green use cases.

External research has previously demonstrated the low power consumption of the pre-Chrysalis IOTA network. The recent Chrysalis upgrade removes many inefficient aspects of the protocol and should further improve energy efficiency. However the IOTA Foundation has traditionally refrained from posting any energy efficiency figures publicly, as measurement is complex and nuanced. The figures can vary considerably depending on the network toplogy and the load.

Given the recent interest in this topic and in response to community requests, we have decided to publish our internal metrics, gathered during Chrysalis development. These metrics demonstrate a significant reduction in energy consumption as a result of the upgrade.

IOTA is designed to be lightweight and a Hornet node can run on low-power devices like Raspberry Pis.
