This study applied the well-established Life Cycle Assessment methodology to an in-depth analysis of drivers of past and future environmental impacts of the Bitcoin mining network.
It was found that, in , the Bitcoin network consumed The main drivers of such impact were found to be the geographical distribution of miners and the efficiency of the mining equipment. In contrast to previous studies, it was found that the service life, production, and end-of-life of such equipment had only a minor contribution to the total impact, and that while the overall hashrate is expected to increase, the energy consumption and environmental footprint per TH mined is expected to decrease.

A consensus mechanism is how the peers in the Bitcoin network continuously agree on the order of newly added blocks and thus secure the data in a decentralized fashion. The miners compete in solving a puzzle, which requires substantial computational power. Every time the miners guess the nonce value an algorithm is applied that maps the data of their suggested block—including the guessed nonce value——to a value of a fixed length.
This output value is called a hash. A miner wins the right to add a new block when this hash is lower than a target value. The hashrate corresponds to the number of hashes guessed per second.
In , the hashrate of the entire Bitcoin network ranged from around 15 to 60 million Tera hashes TH per second. With the increasing popularity of cryptocurrencies concerns were raised regarding the sustainability of Bitcoin, under the rationale that since the Bitcoin network uses a high amount of electricity for mining, its environmental impact might be substantial.
Stoll et al. These numbers are contested by Bendiksen et al. A common feature of the previously mentioned studies is that the assessment of environmental impacts is built on ad-hoc methods.
Despite the substantial uncertainties in the data and choices used in previous models, an explicit uncertainty assessment is lacking in previous studies. There is thus the need to use a solid methodological basis to increase the transparency, validity, and replicability of the environmental assessment of Bitcoin.
Summing up, previous studies assessing the impact of the Bitcoin mining network show contrasting and arguably overestimated results, and a key challenge in this assessment is the scarcity of accurate data on key factors determining the impact of the mining network. This study wants to bring new insights in this area by providing a more detailed analysis of the hotspots of environmental impact in the Bitcoin mining network and by increasing the accuracy in the modeling of regional electricity mixes.
Furthermore, this study wants to add a prospective approach by considering how electricity generation or the geography of the mining network might change in the future. The added value of this analysis is adopting LCA as robust scientific methodology, the use of established databases for assessing environmental impact, including the impact of mining equipment in the analysis, and providing an outlook of future impacts. Methods and Materials.
This study takes both a retrospective and a prospective approach, and two different system models were respectively used. Figure 1 shows the structure of the product system that was analyzed in both cases. The ecoinvent v3. In the text, the IPCC method is reported for the carbon footprint. To understand the uncertainty associated with the background data, Monte Carlo simulations with iterations were carried out for the attributional baseline model and each consequential scenario.
High Resolution Image. The functional unit of the attributional model was defined as computing 1 TH. The information currently available on the location of Bitcoin miners is scarce and inaccurate. However, this information is crucial for estimating the environmental impact of the Bitcoin network, which is highly dependent on the electricity mix of the geographical locations where mining is performed.
A geographical distribution of the Bitcoin mining network was developed in this study based on information available from two previous studies, Bendiksen et al.
Table 1 shows the geographical distribution of the miners used in the attributional baseline model for Table 1. Besides the energy mix, the electricity consumption of the Bitcoin network depends also on the equipment used for mining as it determines the efficiency of mining, namely the electricity consumption per TH computed.
The types of equipment included in the model are taken from Bendiksen et al. Details on the methodology used to derive these values are provided in SI Section 4.
The use of mining equipment involves three main activities: electricity consumption, production, and end-of-life EoL of the equipment. The main contributor to electricity consumption is the use of electricity for mining, determined according to the product specifications of each machine. Large facilities, especially in warmer climates, may require additional energy for cooling and other inefficiency.
The amount of equipment that is produced and hence needs to be disposed of is approximated using machine lifetime. According to Digiconomist, 43 Bitcoin mining equipment has an average lifetime of 1.
For the production of mining equipment, the ecoinvent v3. Similarly, for the end-of-life of the machines, the ecoinvent v3. A sensitivity analysis was carried out to identify how key modeling parameters and modeling assumptions affect the results. First, the sensitivity to the electricity mix and geographical distribution of miners was investigated. Then, three divergent geographic distributions were modeled. Next, the sensitivity of the baseline model with respect to other key parameters was tested.
This allowed to understand the effect of improving mining efficiency or increasing electricity consumption. The consequential approach is fundamentally different from the attributional one as it focuses on quantifying the effect of an increase in the demand for mining.
In the consequential LCA, three different scenarios were modeled. The first model describes a business-as-usual BAU scenario that differs from the attributional baseline model only in the background system: the consequential version of the ecoinvent v3.
The second model describes a technology-sensitive scenario where an increase in demand for mining will be met by installing new mining capacity and investing in the most efficient mining equipment. In other words, in this model only the marginal mining technologies are included. The third model describes a location-sensitive scenario where an increase in demand for mining is met not only by installing efficient mining capacity, but also by changing the geographical distribution of the miners toward locations that allow for more competitive conditions e.
The functional unit of the consequential model was defined as increase in demand for computing 1 additional TH. The consequential model thus investigates the effect associated with a marginal increase in mining rather than the total absolute impact of the whole mining. In the BAU and technology scenarios, the same geographical distribution of miners was maintained as in the attributional baseline model Table 1. In the location scenario, the geographical distribution was adjusted to only include locations where miners are opening new facilities.
With a changing political environment in China, 46,47 miners are looking for new locations with cheap electricity, fast Internet, and low temperatures. According to Bendiksen et al. Thus, in the location scenario the miners were assumed to be equally distributed among Norway, Sweden, Iceland, Russia, Canada, and the U. In the BAU scenario, the same mining equipment as in the attributional model was used, which has an overall efficiency of 0.
In the technology and location scenarios the model includes only the most efficient mining equipment currently on the market. With this distribution of mining equipment an overall efficiency of 0. Regarding additional electricity for cooling and other inefficiency as well as the lifetime of mining equipment, all three consequential scenarios maintain the same assumptions as in the attributional baseline model.
In contrast to the attributional model, all three consequential scenarios are linked to the ecoinvent v3. Results and Discussion. In the attributional baseline model, the energy consumption for every TH mined is That means that the Bitcoin network consumed Deviations from previous studies are due to the fact that, for example, de Vries, 17 Stoll et al.
The study by McCook 22 further uses different assumptions regarding the production of mining equipment and from the documentation available it is not entirely clear how his calculations were done. For , this makes a total of Additionally, the methods of calculating the carbon footprint deviate.

How (And Why) Natural Gas Flaring is Being Used to Mine Bitcoin
In late March , a vulnerability in Jenkins dynamic routing was documented and reported on by Rapid7, but in early June, F5 researchers found a new, more sophisticated campaign exploiting this same vulnerability. References to the specific CVEs leveraged are in the footnotes. While analyzing this script which downloads and executes the cryptominer, F5 researchers found that the code is sophisticated, well obfuscated, and long—about lines versus the typical 20 or so lines. The authors clearly put a lot of time and attention into every step, from developing the malware dropper to creating the executable JAR file and finally, executing the remote code execution RCE in order to install the cryptominer. Notably this script was written in bash and python; it is not compiled code. Though leveraging the Groovy plugin metaprogramming in order to exploit Jenkins Dynamic routing is common, the method the author uses is somewhat unique. When a cryptominer is installed, it uses valuable computational resources in order to mine different cryptocurrencies. Along with rising electric bills, this means your computer would be running at full speed all the time. This can cause heat damage to hardware and slower performance for applications.
Powering Bitcoin Miners with Stranded Carbon
Micro mining refers to the limited capacity mining activity that can be performed by commonly used Internet of Things IoT -enabled home appliances or mobile and hand-held electronic devices. Micro mining was an idea promoted to solve the scalability problem and mass adoption of cryptocurrency by using the limited processing power and memory available in various home appliances—like smart refrigerators, washing machines, air conditioners, and even vacuum cleaners. The idea has not yet succeeded, mostly due to the labor intensity of mining Bitcoin and a lack of IoT consumer adoption. Micro mining essentially allows small devices that are connected to the internet, such as smartphones, e-readers, IoT-connected appliances, etc. These personal and household appliances could then generate small amounts of revenue to help defray their purchase costs or costs of operation.
Attackers Use New, Sophisticated Ways to Install Cryptominers
This huge spike in value has many asking if it is a bubble or if the high price today is here to stay. Finance defines a bubble as a situation where the price of an asset diverges systematically from its fundamentals. Like any asset, Bitcoin has some fundamental value, even if only a hope value, or a value arising from scarcity. So there are reasons to hold it. But our research does show that it is experiencing a bubble right now. Together with Shaen Corbet at Dublin City University, we took as the fundamentals of Bitcoin elements of the technology that underpins it and other cryptocurrencies.

Metrics details. Illicit cryptocurrency mining has become one of the prevalent methods for monetization of computer security incidents. The most popular illicitly mined digital coin is Monero as it provides strong anonymity and is efficiently mined on CPUs. Illicit mining crucially relies on communication between compromised systems and remote mining pools using the de facto standard protocol Stratum. While prior research primarily focused on endpoint-based detection of in-browser mining, in this paper, we address network-based detection of cryptomining malware in general. We propose XMR-Ray, a machine learning detector using novel features based on reconstructing the Stratum protocol from raw NetFlow records. Our detector is trained offline using only mining traffic and does not require privacy-sensitive normal network traffic, which facilitates its adoption and integration. In our experiments, XMR-Ray attained

Bitcoin mining to use 0.5% of world’s electricity
In contrast to traditional forms of money which are controlled using centralized banking systems, cryptocurrencies use decentralized control. This has advantages in that two parties can transact with each other directly without the need for an intermediary, thereby saving time and cost. More and more entities, including private enterprises, are entering into transactions in which they obtain cryptocurrencies. The following are examples of situations in which an entity may obtain cryptocurrencies:. Cryptocurrency mining describes the process in which transactions for various forms of cryptocurrency are verified and added to the blockchain digital ledger. Cryptocurrency miners use large amounts of computing power to solve blockchain algorithms. Once a block has been solved by the miner, he may, depending on the mining algorithm, be entitled to transaction fees as consideration for verifying cryptocurrency transactions and entering them in the blockchain ledger.
