bsv

bsv

A pure and powerful JavaScript Bitcoin SV library.

Principles

Bitcoin SV 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 SV changes

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

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

Get Started

In node.js

npm install bsv

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

  "dependencies": {
         "bsv": "=0.18.0",
          ...
          }

In browser

<script src='https://unpkg.com/bsv'></script>

Documentation

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

Security

We're using Bitcore 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.

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

Build with Gulp

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/moneybutton/bsv/commit/e33b6e3ba6a1e5830a079e02d949fce69ea33546 for v0.12.6).

To verify signatures, use the following PGP keys:

• @gabegattis: https://pgp.mit.edu/pks/lookup?op=get&search=0x441430987182732C F3EA 8E28 29B4 EC93 88CB B0AA 4414 3098 7182 732C
• @matiu: https://pgp.mit.edu/pks/lookup?op=get&search=0x9EDE6DE4DE531FAC 25CE ED88 A1B1 0CD1 12CD 4121 9EDE 6DE4 DE53 1FAC

Build with Webpack

npm run wpbuild

This will generate file named bsv.min.js.

Development & Tests

git clone https://github.com/moneybutton/bsv
cd bsv
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.
