This project provides a WebAssembly (WASM) build of the dual-variant yespower hashing algorithm used by AdventureCoin (ADVC). It supports:
yespower 1.0(after timestamp1553904000)yespower 0.5with personalization string"Client Key"(before timestamp1553904000)
It is optimized for use in web-based miners and JavaScript environments.
Install the Emscripten SDK:
git clone https://github.com/emscripten-core/emsdk.git
cd emsdk
./emsdk install latest
./emsdk activate latest
source ./emsdk_env.shgit clone https://github.com/CryptoDevelopmentServices/YespowerADVC_WASM.git
cd YespowerADVC_WASMSimply run the provided build script:
./build.shThis will compile the yespoweradvc.wasm and yespoweradvc.js files, which can be used in browser or JavaScript environments.
🔔 If you see the message: #warning "Note: building generic code for non-x86. That's OK." — this is normal and expected for WebAssembly builds.
After building, you will get:
yespoweradvc.wasm – WebAssembly binary
yespoweradvc.js – JavaScript loader/glue code
Here's how to use it in a web page:

Module.HEAPU8.set(input, inPtr);
Module._yespower_hash(inPtr, outPtr);
const hash = Module.HEAPU8.slice(outPtr, outPtr + 32);
const hex = Array.from(hash).map(b => b.toString(16).padStart(2, '0')).join('');
Module._free(inPtr);
Module._free(outPtr);
document.getElementById("result").textContent = hex;
}

</html>The WASM version is optimized for compatibility, not raw speed.
For performance mining, use a native binary (e.g., cpuminer or sugarmaker).
This is suitable for learning, experimenting, and building front-end miners.
