Do not use this, it is here just for historical reasons


This is SatoshiLabs fork of Bitpay's Bitcore that uses Bitcoin 0.15.0. It has a limited segwit support. We also have separate branches for some Bitcoin forks (UASF, 2x, Gold, Cash).

We (SatoshiLabs) are not promising to keep these forks "alive", updated and maintained, long-term. For that reason, they are not pushed into NPM, just on github.

However, right now, we are actively using these in production on .

What is also added is support for new smart fees; /utils/estimatesmartfee?nbBlocks=2&mode=economical returns the new smart fees. Similarly, estimatesmartfee (with int bool parameters) is added to the bitcore websocket API.

We do not version Bitcore here, either for mainnet or for the forks; we are using to build debian packages, which are versioned, for all the coins. So this repo might seem a little chaotic, but we are pinning commit hashes for various altcoins in the bitcore-deb repo.

Bitpay's Bitcore has diverged from our code with their recent rewrites and refactors (for example, added bcoin for transaction parsing); we do not plan to merge the big refactors back here. (see )

Following is original Bitcore readme.

NPM Package Build Status

Infrastructure to build Bitcoin and blockchain-based applications for the next generation of financial technology.

Note: If you're looking for the Bitcore Library please see:

Getting Started

Before you begin you'll need to have Node.js v4 or v0.12 installed. There are several options for installation. One method is to use nvm to easily switch between different versions, or download directly from Node.js.

npm install -g bitcore

Spin up a full node and join the network:

npm install -g bitcore

You can then view the Insight block explorer at the default location: http://localhost:3001/insight, and your configuration file will be found in your home directory at ~/.bitcore.

Create a transaction:

var bitcore = require('bitcore');
var transaction = new bitcore.Transaction();
var transaction.from(unspent).to(address, amount);

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.

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


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


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.

This will generate files named bitcore.js and bitcore.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, for v0.12.6).

To verify signatures, use the following PGP keys:
