Bitcore Library

** Bitcoin CASH support version, please use with caution, this is still BETA **

A pure and powerful JavaScript Bitcoin Cash library.

Principles

Bitcoin Cash is an other 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 bitcore-cash has been tested agains the original bitcoin-cash test vectors (see sighash.json in /test). bitcoin-cash modifications in script evaluation has not been implemented yet.

An usage example of ubitcore-lib-cash can be seen at https://github.com/bitpay/copay-recovery

Get Started

npm install bitcore-lib

bower install bitcore-lib

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

  "dependencies": {
         "bitcore-lib-cash": "git@github.com:bitpay/bitcore-lib.git#cash",
          ...
          }

Building the Browser Bundle

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

gulp browser

This will generate files named bitcore-lib.js and bitcore-lib.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 a release commit (for example, e33b6e3ba6 for v0.12.6).

To verify signatures, use the following PGP keys:

Development & Tests

git clone https://github.com/bitpay/bitcore-lib
cd bitcore-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.
