Recently we have introduced to you JSEcoin – JavaScript Embeded Cryptocurrency for Webmasters as an interesting new project that uses JavaScript mining via the browser of users and that can be used to monetize website traffic. But another similar service has gotten much more attention lately as it was found to be used on The Pirate Bay (a torrent website) in the form of an embedded JS miner for Monero (XMR). The service in question is Coin Hive and it allows you users to embed JavaScript miners in their website as a side source of revenue, so the service in itself is not bad or evil or whatever. The problem with The Pirate Bay is that they have introduced the JavaScript code of the miner without letting any of the visitors know, so people started noticing that when they open the website their CPU load skyrockets and that is not fine.

The main problem we are seeing here with a service like that is when users don’t know that you are using their computing resources to mine, you need to tell them or offer them the choice to do it in order to support the website. The default example from Coin Hive does not come with any visual user interface or anything to let the users know there is a miner, but what if you give your visitors a link to click that will open up a page with a miner. They would be able to open up and control the miner as well as monitor it and have that page open and the miner running in order to support the website or the community they are a part of with their computing power. It is an interesting idea and a one that might actually work out well for some people, the problem however is that most of the users would be thinking along the way of abusing a service like that and making profit at the expense of some users. Still, if you find the project interesting and useful you might look into it, just make sure you tell your visitors what you are doing if you embed it on a website in order not to have negative, instead of positive results!

Apart from the embeddable web-based miner using JavaScript the CoinHive service offers some other interesting alternatives to more traditional services such as a Proof of Work Shortlinks service as well as Proof of Work Captcha. Both of these user actual mining of a certain number of hashes before allowing you to forward you to a certain link or to confirm that you are a human and not a bot. Using Proof of Work (mining) for more common things that normally utilize different approaches can actually be a interesting way to improve and yet at the same time monetize some aspects from an already working service. In short you might want to think outside of the box and think of new ways to use crypto mining in a way that you may even reward users for doing the “heavy lifting” in an existing web-based game or a social network for example. Of course computing hashes in a browser with JavaScript is not the most efficient way to do things, especially compared to optimized mining software. We have played around with the miner and the extra PoW-based services available, though do note that we have not embedded this miner into the website here and we would not do it without warning you should we decide to test it live for example.

There is a new closed source Ethereum (ETH) miner that also works with other Ethash-based crypto coins available and it is called Eminer. The miner is available for both AMD and Nvidia GPUs and what makes it really interesting is the integrated local web dashboard that gives you detailed stats for the mining rig the miner is running on. The new Eminer ethash miner v0.6.0-RC1 is written in the Go language and provides performance comparable to that of other top miners for AMD at least with possibly slightly slower hashrate on Nvidia. Eminer comes with support for Stratum and RPC clients with failover, as well as with support for Nicehash’s stratum implementation. There is however a 1% devfee included in this miner software, so have that in mind should you decide to give it a try. The Windows version comes with Asynchronous multiworker mode that searched shares with multiple instances and this can supposedly bring increased by 1% ~ 2% share luck. Binaries for Linux and Mac OS X of the miner are also available.

The real gem here is the web-based interface that gives you an overview of the mining hardware and the current mining process, including a graphical representation of the hashrate over time. YOu get information on the available AMD or Nvidia GPUs and their current status such as clocks, hashrate, temperature and fan speed. This allows for quick and easy overview over web of multiple mining rigs without having to spend time decoding the console output from the miner… that one can use some improvements to be more useful, but probably the focus was placed more on the web-based dashboard. Still this new miner looks promising and useful and it never hurts to have some competition among the crypto mining software.

Since it is a closed software with no source available posted by a new user on Bitcointalk some people might have some concerns you can check a VirusTotal scan of the executable here. Not a guarantee that there are no warnings since it is a new miner that is not based on other existing codebase that gets detected as potential threat by some antivirus software.

There is a new ccminer skunk-krnlx fork (source) available that comes with improved SkunkHash-Raptor performance. The miner is open source and provides the same performance for mining Signatum (SIGT) – the altcoin that has introduced this new crypto mining algorithm. This new free and open source miner does come with a performance very similar to that of the fastest closed source miners for Nvidia GPUs that are available for sale, so you might want to give it a try.

There are no official binary releases available, only the source code, but we have for download a 32-bit Windows binary compiled with VS2013 and CUDA 8.0 that you can try if you are having trouble compiling the code yourself. AMD miners might want to check out the Prospector miner for better performance on Polaris GPUs, though this miner is only available as binaries and is not open source, so proceed with caution.
