## What it is
Bcoin is an alternative implementation of the Bitcoin protocol written in JavaScript and C/C++ for Node.js and browsers. It can run as a full node, SPV node, wallet backend, mining backend, or be used as a general-purpose Bitcoin library.

## Use cases
- run a bitcoin full node in javascript
- build a bitcoin wallet backend
- spv node for lightweight bitcoin verification
- mine bitcoin with getblocktemplate support
- integrate bitcoin consensus rules into a javascript app
- backend for lightning network layer 2

## When to choose
- you need a programmable bitcoin node or wallet in JavaScript/Node.js
- you want browser-compatible bitcoin protocol primitives
- you need a battle-tested consensus implementation used in production

## When to avoid
- you need a simple end-user bitcoin wallet GUI
- you prefer a mainstream implementation like Bitcoin Core with wider ecosystem support
- you need active development - releases are infrequent

## Facets
- artifact type: library
- maturity: maintenance
- function: database, cryptography, networking, http-server, cli, sdk
- domain: blockchain, developer-tools, backend
- platform: browser, cross-platform
- tags: bitcoin, full-node, spv, wallet, mining, blockchain, lightning-network, cryptocurrency, nodejs, javascript
