This pages features an overview of changes made to the Digiconomist website and the models that provide live information on crypto asset sustainability.
Bitcoin Energy Consumption Index Changes
v1.0.9 – May 5, 2025
Updated minimum energy consumption benchmark to Bitmain’s Antminer S21 XP Hyd. Deleted one year of data starting at the time China started to enforce a complete ban on Bitcoin mining activities in the country. As China was home to a majority of global Bitcoin miners before this happened, this ban severely disrupted the assumption of competitive markets on which the Bitcoin Energy Consumption Index is founded. Under these extreme circumstances, outcomes cannot be considered reliable and there does not exist another model that can be used to correct for these values. Time period affected: July 1, 2021 – June 30, 2022. The reason for removing a full year is that the Index is essentially a moving average over the past 365 days, which means that disrupted values continue to affect outcomes for a full year. The network’s minimum energy consumption values during this time are unaffected by this change.
V1.0.8 – Sep 2, 2024
Fixed an error in the Bitcoin Energy Consumption Index data sourcing that affected the time period from the start of June 2024 to the start of September 2024. As a result, the values of the output data were too low for this period. The data values for this time period have been recalculated and updated.
V1.0.7 – Jan 10, 2024
Added sustainability indicators for water consumption and included background information for these indicators in the main body text. Updated minimum energy consumption benchmark to Bitmain’s Antminer S21.
V1.0.6 – May 29, 2022
Assumption on manufacturing lead times fixed at a one year period (previously variable but hovering around one year). No retroactive calculation was performed due to limited impact.
V1.0.5 – Oct 31, 2020
Updated minimum energy consumption benchmark to Bitmain’s Antminer S19 Pro.
V1.0.4 – Nov 7, 2019
Updated minimum energy consumption benchmark to Bitmain’s Antminer S17e.
V1.0.3 – Oct 1, 2019
Removed Bitcoin Cash from index.
V1.0.2 – Feb 13, 2019
Updated minimum energy consumption benchmark to Bitmain’s Antminer S15.
V1.0.1 – Aug 1, 2017
Added data sources to aggregate Bitcoin/Bitcoin Cash.
V1.0.0 – Feb 9, 2017
First official release. Beta period data removed.
V1.0.0-beta – Nov 26, 2016
Beta release.
Ethereum Energy Consumption Index Changes
V2.0.0 – September 15, 2022
Estimation method changed to reflect a new estimate for proof-of-stake Ethereum after “The Merge” (i.e. Ethereum replacing its proof-of-work mechanism with proof-of-stake).
V1.1.0 – May 29, 2022
Retroactively applied a fix to allow electricity costs to reach 100% of miner revenues during a market downturn (previously capped at 60%). Additionally, a fix was applied to properly account for fees after the implementation of EIP-1559.

V1.0.0 – May 27, 2017
First official release.
Dogecoin Energy Consumption Index Changes
V1.0.0 – Jan 15, 2022
First official release.
