Open Source JavaScript Bitcoin Software

Bcoin is an advanced fullnode implementation built with JavaScript/C/C++/Node.js. It is easier to use, faster to learn, and more well-documented than competing implementations. Engineered from the ground up to create scalable, flexible, and efficient production-ready systems with unparalleled code readability. Bcoin is consensus-conforming and adheres to the strict security standards of the original implementation maintained by Bitcoin Core. Bcoin can be integrated into almost any desktop or browser application to enable native payments, on both Bitcoin and Bitcoin Cash networks. Bcoin is the first full node implementation built specifically for production systems at scale. Originally created to be used as backend infrastructure for Purse.io, Bcoin enables companies to spin up consumer-grade bitcoin applications/wallet systems without the long-term concern of scalability, and security.

This is still early technology and there’s a risk of losing all of your funds. We recommend not putting in more money than you are willing to lose. Pocket Money, prebuilt and signed releases with auto-update (recommended for most users). Tin Foil Hat, if you'd rather build it yourself and do it without auto-updates, follow the instructions. To build the mobile app locally, see the README in the /mobile directory for instructions. Running in development mode can allow you to run in full node mode instead of the default neutrino mode, and will also allow you to run in simnet node for testing. The app will use its own lnd data/lnd dir and does not share state with other lnd installations on your system. See setup local cluster on how to set up your simnet cluster for development.
