Cambridge Bitcoin Electricity Consumption Index updated to reflect hardware distribution and hashrate increases

1 year ago

Cambridge researchers revise the widely-cited scale successful effect to grounds indicating periodic overestimation of Bitcoin mining’s energy consumption.

Cambridge Bitcoin Electricity Consumption Index updated to bespeak   hardware organisation  and hashrate increases

Researchers down the well-known Cambridge Bitcoin Electricity Consumption Index (CBECI) person officially revised its methodology to heighten the accuracy and reliability of the Index’s estimates for the archetypal clip since its inception successful 2019.

The CBECI was launched successful July 2019 successful an effort to supply reliable data-driven insights to questions astir Bitcoin mining’s energy-intensive quality and associated biology impact. 

Speaking exclusively to Cointelegraph up of announcement of the revision, caput researcher Alexander Neumueller unpacked the Index’s relation successful providing a comparatively close estimation of the Bitcoin (BTC) network’s energy depletion and contextualizing the information successful a mode that is digestible for the layman connected the street.

Key takeaways from the revised methodology included a absorption connected caller developments successful Bitcoin mining hardware and hash complaint and whether the CBECI was accurately reflecting the changing landscape. The researchers honed successful connected questions astir what had driven important increases successful hash complaint successful caller years arsenic newer mining instrumentality eclipsed older models successful computing power.

Neumueller and his chap researchers noted that the scarcity of hardware-related information posed a important situation arsenic it constricted the CBECI’s quality to accurately measure the types of hardware that miners usage arsenic good arsenic their ubiquity.

This led the researchers to antecedently make a methodology that simulates a regular hardware organisation based connected show and powerfulness usage information of existent hardware. Neumeuller notes that the backbone of the erstwhile CBECI methodology assumed that each profitable hardware exemplary released little than 5 years agone arsenic fuelled the full web hashrate.

This successful crook led to a “disproportionally ample number” of older mining hardware compared to newer models successful the methodology’s assumed hardware organisation during exceptionally profitable mining periods.

The researchers subsequently discovered that much precocious released instrumentality appeared to beryllium underrepresented portion instrumentality nearing the extremity of its beingness rhythm was overrepresented. This prompted the alteration successful the CBECI methodology.

Neumeller past explained however his squad began comparing hashrate increases with United States import information reflecting caller Bitcoin mining hardware deliveries. This was combined with an introspection of publically disposable income information from mining hardware shaper Canaan.

CBECI looked astatine U.S. import records connected Bitcoin mining instrumentality (left) and estimated computing powerfulness derived from import information (right). Researchers utilized the hash complaint (in TH/s) and gross value stated by the shaper and applied an arsenic weighted premix of the pursuing models from Canaan’s Avalon A1246, Avalon A1266, Avalon A1346 and Avalon A1366.

The analysis, which considered a fig of in-depth factors, was utilized to trial the proposal that increases successful web hash complaint tin beryllium attributed to much precocious released mining hardware.

“This proposal was based connected U.S. import data, and we sought further grounds to validate it. If Canaan's income information is typical of the industry, it corroborates this claim.”

Neumueller highlighted a disagreement successful opinion, with critics suggesting that Bitcoin “jeopardizes biology advancements and could exacerbate clime change,” portion supporters reason that the mining manufacture could combat clime alteration and supply different societal benefits.

“However, the intricate quality of the manufacture and the deficiency of accusation are often under-recognised, making country for cherry-picked information points and biased perspectives.”

The CBECI includes a wide scope of affluent information points and visualizations, including the index’s Bitcoin web powerfulness demand, a mining representation reflecting the geographic organisation of Bitcoin’s mining hash complaint arsenic good arsenic a greenhouse state emissions index.

The CBECI and greenhouse state emissions indexes supply 3 antithetic estimates for some sectors, providing a hypothetical scope for these circumstantial metrics.
