Bitcore Flux Library

A pure and powerful JavaScript Flux library.

Principles

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

Get Started

Requires Node.js 24 or newer.

npm install @runonflux/bitcore-lib

const bitcore = require('@runonflux/bitcore-lib');

To work on the library itself:

git clone https://github.com/runonflux/bitcore-lib.git
cd bitcore-lib
npm install
npm test

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.

• Read the Developer Guide
• Read the API Reference

Examples

• Generate a random address
• Generate a address from a SHA256 hash
• Import an address via WIF
• Create a Transaction
• Sign a Flux message
• Verify a Flux 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.

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

Development & Tests

git clone https://github.com/runonflux/bitcore-lib
cd bitcore-lib
npm install

Requires Node.js 24 or later. Run all the tests:

npm test

npm test runs every file under test/ in its own mocha process and checks each outcome against test/inherited-failures.json, the inherited upstream tests that fail at runonflux/bitcore-lib 8f5453f. test/differential.js checks this library against bitcore-lib 8f5453f, installed as the devDependency bitcore-lib-8f5453f, on Flux mainnet blocks and transactions (test/data/flux-mainnet/corpus.json, written by scripts/fetch-mainnet-corpus.js), keys, addresses, HD keys and signatures. A single file runs with npx mocha test/<file>.js.
