Cbs bitcoin mining

While it's hard to say exactly how carbon-intensive cryptocurrency mining is — most miners' locations and energy sources are a closely guarded secret — scientists are worried.

De Vries estimates that bitcoin's yearly carbon emissions are on track to match the city of London's, which is estimated to be One group of researchers at the University of New Mexico has put a price on that pollution, estimating in a paper that every dollar of bitcoin value mined accounts for 49 cents' worth of health and climate damage in the U. Other studies have found that the environmental damage caused by crypto mining is on par with mineral mining. In an article published in Nature Climate Change, scientists warned that if it were to become as widely adopted as other new technologies, bitcoin alone could push the Earth's temperature 2 degrees above historical levels.

This inefficiency is the price we pay for security," said Anton Dek, crypto asset and blockchain lead at the Cambridge Centre for Alternative Finance and one of the researchers on the bitcoin energy tracker. The process of mining a bitcoin involves multitudes of computers competing to solve a complex math problem, in which the first to reach a solution is rewarded with a bitcoin.

The complexity of these transactions makes it difficult, for instance, to hack the bitcoin blockchain. It also means that how much bitcoin you can mine depends on how much computing power you can throw at the problem. That has effectively set off an arms race in which miners invest in even more computing equipment that they keep running 24 hours a day.

And the more expensive bitcoin gets, the more people want a shot at the action.

Showtime refused to comment. New Relic told us it had nothing to do with the mystery code. It appears they were added to the website by its developers. We also asked Code Hive for details on the user account the injected code was mining for. The outfit did confirm to us, however, that the email address used to set up the account was a personal one, and was not an official CBS email address, further suggesting malicious activity.

Coin Hive's mining code was at the center of some attention last week when file-sharing search engine The Pirate Bay admitted it had added the coin-gathering JavaScript on its pages in order to test its profitability in an effort to get rid of ads on its site. The code was poorly configured — web admins are allowed to set the hashing rate — and resulted in people's machines slowing to a crawl, sparking complaints. Following the outcry, The Pirate Bay acknowledged the presence of the mining script, calling it "only a test" and promised to limit the CPU usage to make it less annoying. A few days later, the organization dropped the idea all together.

The huge advantage to the website operator using the code is that not only does the script use someone else's processing power but also their electricity, meaning that you can make money with very little effort. So long as you are willing to annoy your visitors.

Who placed the JavaScript code on two primetime dot-coms? So far, it's a mystery

If Coin Hive wants to be seen as legitimate rather than a tool for hackers and malware authors, it is going to have to rapidly figure out a better authorization system for big websites and work on making itself less attractive to scammers. Meanwhile, ad blocking tools are now killing the JavaScript on sight.
