The dashboard uses a set of hard assumptions that can be updated intermittently as data becomes updated, or more available. For example, information on national energy mixes and grid intensities are typically updated on a yearly basis as energy systems evolve. In addition, the type of hardware used across the network may be updated overtime as older machines are updated with newer products available on the market.
A number of static assumptions are used in the dashboard to inform its outputs including:
• Where no location information of a given node or validator is given, and average emissions factor of 0.29gCO2e/kWh is applied.
• Average Memory Power Drain: 3W/8GB of RAM.
• Average CPU Thermal Design Power: 105W.
In addition, the specific work done by a given node or validator is not specifically known, nor is it directly tracked by the network. Hence, the following assumptions validator utilization rate: 95%; and node utilization rate: 5% are used.
The dashboard also includes information regarding the assumed rate of zero carbon and fossil fuel power from the network. The energy mix definitions used are as follows: zero carbon: nuclear energy, biofuels, wind, solar and hydropower; fossil fuels include gas, coal and oil.
