What is coin mining
The mandate of the Bitcoin Mining Council is to promote transparency, share best practices, and educate the public on the benefits of Bitcoin and Bitcoin mining. Michael Saylor convened a meeting attended by a number of large North American miners in May to discuss energy usage related to Bitcoin mining. At that meeting, the group decided it would be useful to have an open forum where Bitcoin miners could promote transparency, share best practices, and educate the public on the benefits of Bitcoin and Bitcoin mining. The BMC intends to, among other things, hold a quarterly meetup presenting trends in Bitcoin mining, partner with leading industry researchers to gather data and educate the public on Bitcoin mining, and open source best practices from Bitcoin miners to encourage industry growth. There is no cost to join the BMC. The founding members that helped establish BMC will assume the onboarding and operating expenses for the first year of operation.

The Political Geography and Environmental Impacts of Cryptocurrency Mining
Category: Unit Tags: Bitcoin , Coinhive , Cryptocurrency. Cryptocurrencies have taken the world by storm. Recently, browser coin mining has taken off, for a lot of different reasons.
Although the computing power per instance is much less than dedicated hardware provides, being able to utilize many users on various sites more than make up for it. There is already some media coverage on this, such as BBC , and malwarebytes.
Coinhive , one of the more popular browser-mining services out there offers site owners a piece of JavaScript for easy integration. On the official Coinhive homepage, we found detailed documentation on how to integrate the mining scripts onto any given website. Owners can use the easy version:. With higher CPU occupation percentage, end users will likely experience sluggish behavior and poor experience on the websites.
We have been tracking the inclusion of Coinhive mining script coinhive. The number of URLs leading to the download of such similar scripts is astounding. Overall, we have seen over 35, unique URLs associated with coinhive. Based on our observation, the appearance of these scripts can be clearly divided into three categories — standalone, voluntary, and compromised.
It is worth noting that such URLs are always belong to a jibberish[. Of the 35, URLs we collected, 33,, or In addition, there are URLs leading to the same set of. The fact that robots. It is interesting to speculate: why did our customer visit such weird, long, random URLs in the first place? After removing the. The remaining can be further categorized into the following three groups:. Some of these are forums discussing crypto-mining, while others are introducing the concept.
Regardless of the purpose of the websites, we did not find any evidence that such sites are asking user's consent to mine XMRs. This category includes sites that obviously want to include coin-mining scripts to monetize.
While they do provide their normal service to the visitors, browsing these sites do not pop up any sort of warning of coin-mining behavior for the user. A script snippet embedded in such sites can be found here:. What is more interesting is that by searching across the whole URL corpus for coinhive.
We verified that the below is indeed a valid URL leading to a subpage in the porn site. That site does include coinhive.
We speculate that the porn website URL may have included an iframe leading to the. However, this mechanism may have been later abandoned in favor of direct inclusion. Another group of sites seem to have fallen victims of malicious script injection into their vulnerable servers. We found that www. Upon closer investigation, we found that this site is hosting multiple copies of coinhive. A similar situation happens in www. It is quite possible that crypto-mining has become a new injection attack in addition to traditional exploit kits redirections.
Examples include analytics-google[. According to our observation, coin mining integration scripts are rarely obfuscated, which means we can extract the anonymous 'site key' and their configurations easily. Per Coinhive's documentation, the 'site key' is a unique identifier to indicate which beneficiary will be paid, therefore, the attacker has no incentive to garble this field. Here are some interesting stats about the actors and their configurations.
There is a clear winner at the top - ID t3zmp2zg1lia7rujy19d67woezmjj claiming 35, over 36, of all the IDs we were able to retrieve. Surprisingly, querying a website source code search engine like publicWWW only returns 13 results mostly. The remote second and third sites scored and occurrences respectively, along with 8 other IDs topping 10 occurrences.
A large number of IDs only have 1 appearance in our dataset, and these are possibly category 2 or 3 in our integration scenarios described above — mining would benefit themselves rather than a campaign owner.
Unsurprisingly, site key owner t3zmp2zg1lia7rujy19d67woezmjj has all the. In addition, there are URLs such as. In this chart, a special case sitekey stands out. There are sites using it, and it is a predefined variable in previous scripts as opposed to hardcoded string so without dynamic analysis we are not able to retrieve its real content.
We looked at a few samples and it seems that most sites using the sitekey variable are serving mining script to benefit themselves. We found only six out of the entire URL population making more than one call to coinhive. Upon closer inspection, all the calls actually have the same site key, so in summary we did not find evidence of one site serving more than one beneficiary.
We did, however, find out that one site, lottoipros[. If this trend continues, it will become harder to use static analysis to detect crypto-mining sites. The dominant Actor ID t3zmp2zg1lia7rujy19d67woezmjj uses default configuration across all of observed URLs, so we exclude this actor from this analysis to prevent skew.
We also exclude the sites that use mineropts that go almost hand-in-hand with sites using sitekey as their site key. This left us with valid data points. Among these most sites only use 1 thread by default; however, some sites use as many as 4 threads to maximize mining speed. After the default setting which disables throttling the most popular option is to set it at 0. The TLD distribution for domains hosting coinhive. For brevity, we aggregated all TLDs having less than 20 entries into others category.
Clearly, the top suspects are. As expected, typically notorious TLDs like. We checked all associated domains against the current Alexa traffic ranking. The results are astonishing - there are 5 sites in top 2K, 29 sites in top 10K and sites in top 1 million. We sample a few highest-ranking sites and show it here:. At the time of the writing, we can no longer observe coinhive. The highest ranked.
We have attached all these IOCs and their rankings at the end of this blog for the community's benefits. Examples include uptobox[. This means these websites have been active for a long time. Some of them are quite popular based on their Alexa ranking. So, the potential impact of Coinhive can be high in both time and space. Based on the figure below, we can clearly see the emerging trend of these domains.
We further investigated the DNS query pattern of these domains. In particular, the following graph shows the number of DNS queries to these website per hour. Interestingly, we found that some domains exhibit very similar patterns. Although the start time and amount of traffic are slightly different, the overall pattern of traffic is very much similar in shape. This is another indicator that these domains potentially belong to the same campaign launched by the same owner.
In addition, we analyzed the distribution of IPs to which these domains were resolved. We identified 1, IPs in total, located in 47 different countries with the majority being in US. Below is the figure showing the country-level distribution of these IPs. Through querying public Whois server as well as Domaintools, we obtained valid whois records of 1, domains.
In contrast, most. This looks to be a different campaign than the. We see similar registration trending on. Finally, after we exclude the suspected campaign domains. These domains are most likely either embracing the new crypto-mining monetization fever, or compromised by attackers to take advantage of their established reputation and high-volume visitors.
In this section, we analyze the demographics of visitors to such sites to shed some insights on their real-world impact. This figure shows the general geographic distribution of visitors to crypto-mining sites. While the US clearly dominates in total visiting counts, Europe and Asia Pacific is not too far behind.
This graph indicates a broad spectrum of victims all across the globe. We only log a query when customer s using the same device visits the site for the first time in a TTL window. This does not count duplicate visits to the same site within a short timeframe.
Therefore, the visits estimations are a lower bound. As AdGuard has pointed out, the use of coinhive or similar mining services is itself not a malicious activity, it is how they are used that makes the sites malicious. Unfortunately, for the sites that we were able to observe engaging in crypto-mining activities, none of them has prompted the user with any sort of warning, let alone providing the kill switch for mining.
To protect yourself from this fast-growing threat, we recommend two options:. Please enter your email address! Please mark, I'm not a robot!
Bitcoin Miners’ Revenue Rises 206% In 2021, Says Study. Can Crypto Mining Be Profitable?
But a profile of the town of East Wenatchee, Washington, by Paul Roberts in Politico Magazine is a must-read revelation about the physical reality of bitcoin mining. Whatever else bitcoin might be, it is—first and foremost—a way of converting electricity into money. Bitcoin mining is what we call programming computers to do arbitrarily complicated calculations in a puzzle competition that gets harder as time goes on. The hardware and software necessary to do this are, more or less, commoditized. Mining has always been an aspirational name, but if we accept the metaphor, the miners are mining electricity.
Can You Still Mine Bitcoin and Other Crypto From Home?
Subscriber Account active since. The cryptocurrency boom of attracted interest from people looking for how to profit from the nascent asset class. Staking coins to earn interest and spending them in metaverses were just some of the ways that more crypto investors jumped on the bandwagon. Additionally, crypto mining remains one of the most viable ways to participate in the upside of digital currencies. In practice, miners' computers compete by solving complex mathematical equations that help verify digital currency transactions and update the shared ledger called the blockchain. Their reward for solving these problems is a share of the cryptocurrency that's associated with the blockchain they are part of. Since cryptos are decentralized, meaning that no governing intermediaries are recording each transaction, miners are essential to keeping the crypto ecosystem alive. But mining is not without current and future roadblocks. The environmental impact of its electricity usage is a persistent concern. In , miners fled China after the government banned mining in some provinces.
Is it game over for Kazakhstan’s Bitcoin miners?
Since China outlawed cryptocurrency mining in June , neighbouring country Kazakhstan had become a significant location for Bitcoin miners. The expanse of space, warehouses and factories meant that mining rigs could be easily installed and powered at a lower cost than other Bitcoin-hungry locations. However, Alan Dorjiyev, president of the National Association of Blockchain and Data Centres Industry in Kazakhstan, believes that the issues experienced by Bitcoin miners in the country are now over. He says there is no threat of further internet shutdowns, but should accessibility issues occur, mining farmers are considering satellite options to ensure there is a reserve connection to the internet.
What Will Happen After All Bitcoin Are Mined?
A cryptocurrency , crypto-currency , or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank , to uphold or maintain it. Individual coin ownership records are stored in a digital ledger , which is a computerized database using strong cryptography to secure transaction records, to control the creation of additional coins, and to verify the transfer of coin ownership. In a proof-of-stake model, owners put up their tokens as collateral. In return, they get authority over the token in proportion to the amount they stake. Generally, these token stakers get additional ownership in the token over time via network fees, newly minted tokens or other such reward mechanisms.
Quantum computers and the Bitcoin blockchain
Four years ago, the Scrubgrass power plant in Venango County, Pennsylvania, was on the brink of financial ruin as energy customers preferred to buy cheap natural gas or renewables. Then Scrubgrass pivoted to Bitcoin. Today, through a holding company based in Kennerdell, Pennsylvania, called Stronghold Digital Mining that bought the plant, Scrubgrass burns enough coal waste to power about 1, cryptocurrency mining computers. These computers, known as miners, are packed into shipping containers next to the power plant, the company stated in documents filed with the U. Securities and Exchange Commission ahead of its initial public offering.
This Tesla owner says he mines up to $800 a month in cryptocurrency with his car
When residents of an affluent estate community in Alberta started hearing noise from a nearby power plant, they didn't expect their complaints of sleepless nights would lead to a months-long investigation that would find a bitcoin mining operation had set up shop without approval. Now, Link Global, the company behind the site, is being ordered by the province's utility commission to shut down two plants until it can prove it's allowed to operate — a move the company says will cost jobs and cause the oil and gas infrastructure in which it operates to sit dormant. Jeff Kocuipchyk first started hearing the noise last fall.
Cryptocurrency Mining: How Is Bitcoin Mining Done?
RELATED VIDEO: Why I'm No Longer GPU MiningCryptocurrency mining is the process where specialized computers , also known as nodes or mining rigs, validate blockchain transactions for a specific cryptocoin and, in turn, receive a mining reward for their computational effort. Rigs use the latest processors e. Using standard personal computers for mining is not advisable as most lack the computational power to handle mining-level processing. With a fleet of nodes or a pool, a group of individual miners can combine computational effort, dubbed hash rates, to win block rewards and split the earnings according to contribution. Blockchains require a protocol for achieving a decentralized consensus to verify the integrity of new blocks, and in crypto mining, this consensus mechanism is proof-of-work PoW.
The ultimate guide to privacy protection. Stop infections before they happen. Find the right solution for you. Featured Event: RSA Cryptojacking is a form of malware that hides on your device and steals its computing resources in order to mine for valuable online currencies like Bitcoin.
By Matthew Sparkes. Bitcoin is a digital currency which operates free of any central control or the oversight of banks or governments. Instead it relies on peer-to-peer software and cryptography. A public ledger records all bitcoin transactions and copies are held on servers around the world.
