Mirai malware repurposed to mine Bitcoins using slave IoT devices

A nonprofit, independent media organization dedicated to telling stories of climate solutions and a just future. As more miners join the network — lured by the skyrocketing value of the bitcoin they receive in exchange for their work — the puzzles get harder, requiring ever greater amounts of processing power, and thus electricity, to solve.

Bitcoin mining is now estimated to gobble up more electricity than many entire countries. The energy used by the Bitcoin network in a single year could power all the tea kettles in the United Kingdom for over three decades. Proponents of Bitcoin would have you believe that many or even most mining operations are in far-flung locations using renewable energy that otherwise would have gone to waste.

Jack Dorsey and Elon Musk, whose respective companies Square and Tesla have invested heavily in Bitcoin, claim the cryptocurrency will actually hurry the green energy transition by steering investment into renewables. A paper prepared by Square predicts that electricity producers and Bitcoin miners will soon become one and the same. Greenidge Generation, a former coal power plant that converted to natural gas and began a Bitcoin mining operation, is positioning itself as part of the clean energy future.

Grist thanks its sponsors. Become one. To support our nonprofit environmental journalism, please consider disabling your ad-blocker to allow ads on Grist. Here's How. After belching noxious fumes and dumping toxic coal ash into a nearby landfill for seven decades, the plant was poised to be remediated and reused.

When Greenidge applied for permits to restart operations, it claimed it would be generating power to meet existing electricity demand. By , the plant was no longer producing power for the public at all.

In an attempt to claw back the tens of millions that Atlas invested to convert the plant to natural gas, Greenidge turned to mining Bitcoin. As Greenidge increased its mining capacity last year, there was a corresponding jump in its contributions to global warming.

The equivalent of over , metric tons of carbon dioxide were emitted over the course of last year, a volume comparable to putting nearly 50, new cars on the road.

In late March, the company revealed plans to merge with Support. In its announcement, Greenidge said it wants to more than double its mining capacity on Seneca Lake by July — and to double it again by the end of , at which point it will total 85 megawatts.

Greenidge also said that the company plans to replicate its vertically integrated model — cryptocurrency mining at the source of energy production — at other power plants, with a goal of at least megawatts of combined mining capacity by To accomplish that, the company would have to acquire and open at least four other power plants of similar capacity.

Atlas Holdings itself partially owns five power plants in New Hampshire that have more than 1, megawatts of combined capacity. In April, a cryptocurrency mining company called Digihost moved to acquire a megawatt natural gas-fired plant in Niagara County, New York. It could theoretically happen at any aging fossil fuel plant around the country: A source of dirty energy that has outlived its profitability could find a second life as a Bitcoin mining operation.

Although emissions from Bitcoin mining have global consequences, many of the locals opposing Greenidge are equally concerned about its effects on water quality and wildlife. In late March, Phil and Linda Bracht, two of the 30 petitioners on the lawsuit against Torrey, the county planning board, and Greenidge, took me and another petitioner, Carolyn McAllister, out in their boat to get a look at the plant from the water.

All three live on Seneca Lake, just a mile from Greenidge. The first part of the facility to catch the eye is its giant intake pipe, which is 7 feet in diameter and extends further than the length of two football fields from the shore over the water, like an elevated train to nowhere, before dropping below the lake surface. This is where Greenidge can draw up to million gallons of fresh water per day to cool the plant.

Like all thermoelectric power plants, Greenidge uses steam to spin the turbines that produce electricity, but the steam has to be condensed back to water by exchanging heat with the fresh water before it can be reused. Once-through cooling systems like this — where water is used once and then expelled at a higher temperature — require vast amounts of water, with consequences for both wildlife and water quality.

In recent years, fishers have reported fewer and smaller catches on the lake. John Halfman, a professor of geoscience and environmental studies at Hobart and William Smith College on the northern end of Seneca Lake, says the size of the biggest fish caught in the derby has been steadily decreasing, while the time it takes to make a catch is increasing.

Michael Black, a petitioner and fisherman going on his 50th summer living on the lake, said he used to catch between 60 and lake trout each year from his dock south of Greenidge. While there are multiple reasons fish might be suffering, Black worries that hot water discharges are exacerbating the threats they face. Tiffany Garcia, a freshwater ecologist at Oregon State University, wrote a letter to the Town of Torrey raising similar concerns about the effects of hot water discharges on the larger lake ecosystem.

Residents fear that warmer waters will also increase the likelihood and severity of harmful algal blooms, or HABs, near Greenidge. While the presence of blue-green algae or cyanobacteria is normal in lakes, a small number of these organisms produce potent toxins that can be dangerous or even fatal for people and other animals.

Under the right conditions — which include lots of sun, still water, and, crucially, heat — these algae can explode in vast, dangerous blooms that are becoming increasingly common in the U. Gregory Boyer, the director of the Great Lakes Research Consortium at the State University of New York, studied the effect of artificially increasing water temperature by just 2 degrees on Lake Champlain.

That small change resulted in a surge of bacteria growth, with toxic species of bacteria increasing to a greater degree than nontoxic species. In earlier lawsuits challenging permits the DEC issued to Greenidge, Boyer submitted affidavits on behalf of local environmental groups saying that the large discharges of heated water from Greenidge could increase HABs in the area and should be studied further.

Gary McIntee, who lives just south of Greenidge, told me that the water flowing down the Outlet is often flush with nutrient-rich runoff from farms as well as discharge from a wastewater treatment plant upstream, creating an ideal mix for HABs. HABs would render their only source of running water unusable. As the DEC points out , not even boiling, chemical disinfectants, or water filters will protect people from HABs and their associated toxins.

HABs can also overwhelm industrial water filtration systems , temporarily rendering public water undrinkable. And as winemaker Vinny Aliperti pointed out, algal blooms keep the tourists away. Greenidge Generation vigorously denies that its plant is having an adverse impact on the environment.

Those drives, however, can be turned off whenever the plant needs maximum water flow. Greenidge also affirmed that it is on schedule to install protective screens by However, although there are specific fishing regulations upstream from the Greenidge discharge canal, the lower part of the Outlet is also a designated trout stream ; this explanation also does not account for the trout that live in Seneca Lake itself.

However, as Boyer told me, the number of HABs was down across the region in , likely because of high winds over the summer. Finally, Greenidge reiterated that its activities are all within the limits set by its permits from the DEC and the U. In March , the plant hired McKeon, a lobbyist at Mercury Public Affairs and the founder and former executive director of Republicans for Cuomo, which organized bipartisan support for the now-governor during his first run for the office.

Environmentalists have repeatedly challenged this decision in court. Instead, the question should be: Is the plant more harmful than no plant at all? For example, since the DEC has recommended new and repowered plants use so-called closed-cycle cooling, in which cooling water is recirculated through the plant instead of discarded, significantly reducing wildlife mortality from impingement and entrainment, as well as the volume of hot water discharges.

Of course, that was before the plant started mining hundreds of thousands of dollars worth of Bitcoin every day. So somebody is greedy. At the end of April, the Town of Torrey gave the company a green light to build four new buildings to house additional Bitcoin-mining hardware. Before leaving town, I spent some time on the Keuka Outlet Trail. It follows the stream that connects Keuka Lake to Seneca Lake, running over an old railway, and ends near the Greenidge property line, which is posted liberally with no-trespassing signs.

The stream used to power an industrial thoroughfare. In there were seven gristmills, 14 sawmills, an oil mill, four carding machines for processing wool and other fibers, as well as multiple distilleries. A nonprofit has since transformed the area into a nature retreat with a wide gravel path for walking, running, and biking, well-situated benches for moments of quiet repose, and water access for fishing or boating.

This could have been the fate of an old coal-fired power plant on Seneca Lake, which in its later years produced energy people rarely needed and was too costly to run at a profit. Nearby residents might have breathed easier, and there would have been one less threat to Seneca Lake and the animals and people who depend on it.

To solve the problem that the safety data in the process of coal mine production are easy to be maliciously tampered with and deleted, a mine consortium blockchain data security monitoring system is proposed. The coal mine consortium blockchain includes supervision department, builds favourable centralized and decentralized production mode, and improves PBFT Practical Byzantine Fault Tolerance consensus mechanism to implement practical coal mine safety production. The evaluation shows that the architecture we proposed is more appropriate and efficient for the mine Internet of Things than the traditional blockchain architecture. The Hyperledger Fabric platform is used to build the mine consortium blockchain system to achieve the sensor data reliability, node consensus, safe operation automation management, and major equipment traceability. However, in the actual mining process, there are many mining problems, which may cause serious safety accidents to occur [ 1 ].

Hyperledger Member companies are hiring. Hyperledger Foundation hosts a number of enterprise-grade blockchain software projects.

RIYADH: Russian online retailers have registered a growing demand for new and used cryptocurrency mining machines, the Russian business daily Kommersant reported. This year, the demand for application-specific integrated circuit machines has doubled dramatically while video cards have been in short supply which has driven prices up. Searches for hardware designed to mine bitcoin or ASICs on the Russian classifieds site increased 14 times year over year as supply increased. The most sought-after products were the Whatsminer ming rigs manufactured by the Chinese company Microbt, for which the demand increased 23 times. Meanwhile, searches for Antminers built by Beijing-based Bitmain were 11 times larger than last year's figure.


House members pushed back on crypto CEOs' assertion that bitcoin's energy consumption is actually a "feature not a bug. A mining farm for BitRiver, one of the largest Russian cryptocurrency mining companies that exploits excess hydroelectric power. For years, cryptocurrency has rivaled entire nations in terms of energy use, and US lawmakers are just now starting to investigate how crypto mining operations could be undermining global efforts to combat climate change. This question was the subject of a House Energy and Commerce subcommittee hearing on Thursday that broadly examined the carbon footprint of cryptocurrencies like bitcoin and ethereum. The panel addressed a growing refrain that certain types of crypto transactions are catastrophically energy intensive and are extending the lifetime of fossil fuel resources. Committee members also questioned some of the promises made by crypto boosters, such as the claim that miners can actually help stabilize energy grids. Diana DeGette said during introductory remarks. The crypto CEOs on the panel unanimously testified that mining operations can incentivize the production of clean, renewable energy.

China’s latest crackdown on bitcoin, other cryptocurrencies shakes market

RELATED VIDEO: What is Bitcoin Mining? (In Plain English)

The cryptocurrency was invented in by an unknown person or group of people using the name Satoshi Nakamoto. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services. Bitcoin has been criticized for its use in illegal transactions, the large amount of electricity and thus carbon footprint used by mining, price volatility , and thefts from exchanges.

Burstcoin was the first coin to use the PoC algorithm and utilizes the empty space on a miner's hard drive for mining.

Why C4? The cryptocurrency space is exploding with new startups. These companies and those already established in the space are constantly seeking talent with a strong understanding of cryptocurrencies. Prior to C4 there was no way for these hiring managers and placement firms to validate Bitcoin knowledge in their candidates like they can with other knowledge such as networking, security, and accounting. C4 provides certifications so that professionals can assert their knowledge in cryptocurrencies the same way they are able to assert other skills. The CryptoCurrency Certification Consortium is a non-profit organization that provides certifications to professionals who perform cryptocurrency-related services.
