How to Monetize Your Website with Cryptocurrency Mining

Last week there was an article pointing out that hundreds of websites have been hacked to add bitcoin cryptocurrency mining scripts into them. Essentially what happens is that a Javascript library is added to the page, and as long as the page is open, the Javascript through the browser will use the local CPU to perform bitcoin cryptocurrency calculations, and the person holding the bitcoin key can make money for any hashes that are uncovered.

The consumer may not know that their device is crunching some pretty heavy numbers, but may notice faster battery drain, or perhaps the device getting warm to the touch.

Since mining bitcoin cryptocurrency is a CPU intensive thing - I would imagine that 2 instances would be competing for resources, and might not be the most efficient way to mine bitcoin.

FROM httparchive. I have timing stats for all of the sites than mine bitcoin. The data is similar at every decile, so for simplicity, I will only report the median values here. In this chart, I am comparing the median site that mines bitcoin to the median value for all mobile sites in the HTTPArchive:. This is not terribly surprising, right? The site is throwing another process on the CPU that we know is going to use as much CPU as possible - and that will impact the page loading especially on a mobile device.

What else can we learn about bitcoin cryptocurrency mining in the Browser? The Coinhive API lists a bunch of different parameters that can be configured in your mining operation.

To see these, we need to get the bodies where the Coinhive JavaScript is called:. There are only results from the pages found. There are only 16 matches of and a manual check shows that none are being used in reference to the CoinHive scripting.

So basically - if a site has bitcoin mining running - it will mine on your phone as well. We now know that every site that mines bitcoin will do it on your phone… So how hot is your phone going to get? The mining API has parameters to adjust how many threads to use for mining the default is navigator. The remaining sites have 61 with Javascript parameters, but 96 have a simple value. How much CPU will these threads use? In the Coinhive API, you can configure the throttle on your mining operation.

In my query for throttling parameters, I find sites that set this parameter. There are a small number of websites on mobile, on desktop that mine bitcoin cryptocurrency using the CoinHive JavaScript library on their home page. It may be the case that adding bitcoin cryptocurrency mining to your site allows to to earn money without using ads. However, the data presented here shows that there is a performance impact to the addition of these mining libraries to your site. Nice digging. I get the really strong feeling that this is going to be getting worse very quickly.

Other miner scripts: load. Wow really interesting. Some awesome analysis here! The query below shows which cryptocurrency libraries are most popular -. It looks like coinhive seems to be the most prevalent, followed by jsecoin and crypto-loot -. Also, it occurred to me that some sites might be using more than 1 crytpocurrency mining library.

Running the following query, I was able to see that there are 4 sites using 3 libraries and sites using 2 libraries! Many of the sites using 2 libraries were a combination of coinhive and coin-hive, but there were still a handful that used a combination of coin-hive and cryptoloot or coin-hive and jsecoin. Explore the results. About Trends Stats Reports Discuss. The most popular JavaScript library for this is CoinHive.

The site is throwing another process on the CPU that we know is going to use as much CPU as possible - and that will impact the page loading especially on a mobile device So, how much more CPU is used when JavaScript bitcoin cryptocurrency mining is going on? To see these, we need to get the bodies where the Coinhive JavaScript is called: select page, url, body from httparchive.

Conclusion There are a small number of websites on mobile, on desktop that mine bitcoin cryptocurrency using the CoinHive JavaScript library on their home page. Web transparency code of ethics. HTTP Archive project vs. This thread has already influenced one of the affected websites!
