Bitcoin Sustainability Report November 2018

The Bitcoin price crashed again in November, leading up to the first significant drop in Bitcoin’s energy consumpion ever recorded. Although this may sound as good news, it’s not much more than a pyrrhic victory. In fact, it merely jumpstarts concerns regarding Bitcoin’s e-waste generation. According to F2Pool founder Mao Shixing 600,000-800,000 mining machines were shut down over the past few weeks. Given how these machines are hardwared for a singular purpose, becoming e-waste is their next stop. The highlights of the past month are as follows:

  • Mining revenues dropped more than 20 percent.
  • Mining revenue from transaction fees increased by 23 percent.
  • The average fee per single transaction was $0.54.
  • The total network power consumption decreased by almost 11 percent.
  • The average energy consumption per transaction was down by around 17 percent, and amounts to 684 KWh per unique transaction (enough to power 1 U.S. household for more than 23 days).

Digiconomist is committed to promoting (the development of) sustainable blockchain technology. Blockchain protocols such as Bitcoin currently run on the energy-slurping proof-of-work algorithm (creating these proofs of work is better known as “mining”). The Bitcoin Energy Consumption index is a key tool that was created to provide insight into this energy consumption amount, and raise awareness on the unsustainability of the proof-of-work algorithm. The sustainability report uses historical data from the Bitcoin Energy Consumption Index to summarize the sustainability progress and performance of the Bitcoin protocol over the past month.
