bitcore-lib-cash

Bitcore Library

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 bitcore-lib-cash can be seen at https://github.com/bitpay/copay-recovery

Contributing

Please send pull requests for bug fixes, code optimization, and ideas for improvement. For more information on how to contribute, please refer to our CONTRIBUTING file.

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, https://github.com/bitpay/bitcore-lib-cash/commit/e33b6e3ba6a1e5830a079e02d949fce69ea33546 for v0.12.6).

To verify signatures, use the following PGP keys:

• @matiu: https://pgp.mit.edu/pks/lookup?op=get&search=0x9EDE6DE4DE531FAC 25CE ED88 A1B1 0CD1 12CD 4121 9EDE 6DE4 DE53 1FAC

Development & Tests

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