Legg merke til overhead som blir nemnd i denne kommentaren (ev. også i sjølve artikkelen?):

Do your energy figures allow for just the ASIC characteristic or have you factored other inefficiencies (especially in PSUs, cooling, etc.)? 30 Mar 2017 09:46 UTC

There is also the PUE to consider (overhead at the data center level) which is typically very low for mining farms, 1.05 or so. But the *lower and upper bounds* do not need to take into account the PUE. The lower bound, by nature, needs to assume the overhead is zero. And the upper bound is such a worst-case & unrealistic estimate (by assuming miners deploy the least efficient hardware) that it must surely already overestimate power by at least 5%.
For my *best guess* estimates, in theory I should add 5%. But the variance is pretty large at 470-540 MW and not meant to be 5% accurate, so it would not be useful to do so. 30 Mar 2017 21:13 UTC

As a first step, we study Bitcoin system, its mining process, and its resource requirements. Mining is a necessary process for the creation of bitcoins and verification of transactions. The process also makes the system decentralized and maintains security and trust in the system. Mining, which is tied to the solution of a complex crypto-puzzle, requires significant computing power. This resource demanding process has a significant impact on energy consumption. Our research looks at how the complexity of the problem to commit a transaction to the blockchain and the transaction volume impact computing capacity and energy consumption. We use data from January 2009 to October 2017 to analyze the problem. We highlight how the complexity, transaction volume, and price of bitcoins affect the mining capacity of miners. We find that the energy demand from mining activities will exceed 30,582 MW per month at 400 transactions/second.

Although Bitcoin does present several forward-looking innovations, it also integrates a very old concept into its digital architecture: the mining of precious metals. Even though Bitcoin explicitly invokes mining as a metaphor and gold as an example for understanding the cryptocurrency, there has been little critical work on the connections between Bitcoin and previous metalist currency regimes. The following essay proposes a historical comparison with colonial South American silver mining and the global currency regime based on the New World silver peso it created as a way to interrogate Bitcoin. The comparison with colonial South America, and specifically the silver mining economy around the Cerro Rico de Potosí, will help to develop a historical and political understanding of Bitcoin's stakes, including questions of resources, labor, energy, and ecology. Mining and the extractive apparatus that accompanies it always imply massive-scale earthworks that reshape the planet itself, a process known as terraforming. The Potosí comparison will reveal Bitcoin to form part of a similar process of digital primitive accumulation we can provisionally name cryptoforming.

Due to Bitcoin’s growing popular appeal and merchant acceptance, it has become increasingly important to try to understand the factors that influence its value formation. Presently, the value of all Bitcoins in existence represent approximately $7 billion, and more than $60 million of notional value changes hands each day. Having grown rapidly over the past few years, there is now a developing but vibrant marketplace for bitcoin, and a recognition of digital currencies as an emerging asset class. Not only is there a listed and over-the-counter market for bitcoin and other digital currencies, but also an emergent derivatives market. As such, the ability to value bitcoin and related cryptocurrencies is becoming critical to its establishment as a legitimate financial asset.Using cross-sectional empirical data examining 66 of the most widely used cryptocurrencies, a regression model was estimated that points to three main drivers of cryptocurrency value: the level of competition in the network of producers, the rate of unit production, and the difficulty of algorithm used to “mine” for the cryptocurrency. These amount to relative differences in the cost of production of one digital currency over another at the margin, pointing to differences in relative cost of production – electricity goes in, cryptocurrency comes out. Using that as a starting point, a no-arbitrage situation is established for Bitcoin-like cryptocurrencies followed by the formalization of a cost of production model to determine the fair value of a
