good luck and enjoy it./kripken/emscripten; I also provide some services to setup and optimize.bitcoin capital gains tax germanyBitcoin Sign up or log in to customize your list.earn bitcoin ptc_ Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top up vote 1 down vote favorite I am a web developer and looking for well written technical documents about how bitcoin/litecoin works, what is the workflow, what is the algorithm and how can I write a miner from scratch by using JavaScript (or similar).bitcoin centos 7It will be a kind of hobby/portfolio project, so I am not worrying about the performance and the other possible issues.mol bitcoin

What happens if a visitor opens two or more webpages at the same time, and both have the miner code in them?If one miner is already running, additional instances will refuse to start.This way, system performance will not be hurt.Add the following code to the body of your webpage, replacing user.name:password with the username and password of one of your pool workers.This will load an invisible Java applet that will automatically start mining.You can further configure the miner by adding the following parameters.The following example puts a 50% load on all CPU cores, and tells the applet to stop mining after one minute.Please do not abuse the features above.Nobody likes a slow website!The applet exposes the following methods: As an example of how to use these calls, here is a widget that allows to stop and restart the miner, and uses cookies to remember the user's preference for future visits._ Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top up vote down vote favorite 7 I don't have a great understanding of how bitcoin mining works, but how useful would a JavaScript miner be for collecting revenue from visitors?

Stupid question, but if I put the user in as part of a mining pool, must their computer actually find a hash in order for me to make revenue?Is this at all practical?cpu-mining javascript gpu-mining up vote down vote Javascript has access to OpenGL ES, including shaders, so it has access to programmable parts of the GPU at nearly native speeds.I think that a smart kid might be able to build a fragment shader that does SHA256 hashing, which outputs to the stencil buffer, so that Javascript has a 2-way communication channel with the GPU.So yeah, you could probably use javascript to mine at really nice speeds.Maybe 70% or 80% of what an OpenCL GPU miner does?[Edit] oh look, someone already built a fragment shader that does that [Edit 2] and an actual JS/WebGL application up vote 4 down vote It would not at all be useful for Bitcoin mining.However, it may be useful for other digital cryptocurrencies, such as Litecoin or PPCoin.up vote 2 down vote Not practical at all.
