AcampMiner

A module for the mining feature in Aerfaying Mozhua platform.

Why this?

• Pretty fast, using worker and WebAssembly (If avaliable) for boosting.
• Planning GPU calculation (WebGL2), for further performance.

Development usage

Testing

Using npm:

npm i
npm start

Or yarn:

yarn
yarn start

Then access http://localhost:8080/ by your browser to start benchmark.

Building

Add --production flag if you need.

Using npm:

npm build --production

Or yarn:

yarn build --production

Build wasm requires Emscripten, then execute this command to generate:

emcc Miner.c -O2 -s EXPORTED_FUNCTIONS=['_sha1'] -s MALLOC=emmalloc -s MODULARIZE=1 -s ALLOW_MEMORY_GROWTH=1 -s SINGLE_FILE=1 -s STRICT=1 -o Miner.js

Then some files will appear at the dist directory, lib.js is the module.
