The core aim of this project is to provide a completely open source, browser based, Monero miner. It has a companion project, my fork of Snipa's xmr-node-proxy which adds a WebSocket based branch for allowing this miner to connect through to various mining pools.
Whilst browser mining can be used maliciously, there are many non-malicious use-cases, such as charitable donations (the very reason this project started). A defining aspect to whether web mining is done in a fair way is that of user consent. My recommendation is therefore to ensure the end-user knows the page will be mining and offer them controls such as starting and stopping, and options for how much processing time the mining should use.
To compile, you first need a working setup of the WebAssembly toolchain. Follow instructions at webassembly.org.
Then simply run make in the root directory of this repository. This will output to the build/debug folder.
For an optimized release version, just run make TYPE=release.
To test locally, just tack run onto the end of the above commands, which will start a local server for testing (required to load the WebAssembly module).
