Multicore Lib Cash

A pure and powerful JavaScript Bitcoin Cash library.

Principles

Bitcoin Cash is another powerful peer-to-peer platform for the next generation of financial technology. The decentralized nature of the Bitcoin network allows for highly resilient bitcoin infrastructure, and the developer community needs reliable, open-source tools to implement bitcoin apps and services.

Bitcoin Cash changes

Bitcoin cash uses a different sighash for transaction signatures. The implementation in multicore-cash has been tested against the original bitcoin-cash test vectors (see sighash.json in /test). bitcoin-cash modifications in script evaluation have not been implemented yet.

Get Started

npm install multicore-lib-cash

Adding Multicore Cash to your app's package.json:

"dependencies": {
    "multicore-lib-cash": "=0.18.0",
    ...
}

Documentation

The complete docs are hosted here: multicore documentation. There's also a multicore API reference available generated from the JSDocs of the project, where you'll find low-level details on each multicore utility.

Examples

• Generate a random address
• Generate a address from a SHA256 hash
• Import an address via WIF
• Create a Transaction
• Sign a Bitcoin message
• Verify a Bitcoin message
• Create an OP RETURN transaction
• Create a 2-of-3 multisig P2SH address
• Spend from a 2-of-2 multisig P2SH address

Building the Browser Bundle

To build a multicore-lib full bundle for the browser:

gulp browser

This will generate files named multicore-lib-cash.js and multicore-lib-cash.min.js.

You can also use our pre-generated files, provided for each release along with a PGP signature by one of the project's maintainers. To get them, checkout the releases.

Development & Tests

git clone https://github.com/bitpay/multicore-lib-cash
cd multicore-lib
npm install

Run all the tests:

gulp test

You can also run just the Node.js tests with gulp test:node, just the browser tests with gulp test:browser or create a test coverage report (you can open coverage/lcov-report/index.html to visualize it) with gulp coverage.

Security

We're using Multicore in production, as are many others, but please use common sense when doing anything related to finances! We take no responsibility for your implementation decisions.

If you find a security issue, please email [email protected].
