Btcnano Library

A pure and powerful JavaScript Btcnano library.

Principles

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

Get Started

npm install btcnano-lib

bower install btcnano-lib

Documentation

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

• Read the Developer Guide
• Read the API Reference

To get community assistance and ask for help with implementation questions, please use our community forums.

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 Btcnano 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].

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 btcnano-lib full bundle for the browser:

gulp browser

This will generate files named btcnano-lib.js and btcnano-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/bitcoinnano/btcnano-lib/commit/e33b6e3ba6a1e5830a079e02d949fce69ea33546 for v0.12.6).

To verify signatures, use the following PGP keys:

• @braydonf: https://pgp.mit.edu/pks/lookup?op=get&search=0x9BBF07CAC07A276D
• @pnagurny: https://pgp.mit.edu/pks/lookup?op=get&search=0x0909B33F0AA53013

Development & Tests

git clone https://github.com/bitcoinnano/btcnano-lib
cd btcnano-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.
