Enterprise-level Bitcoin and Blockchain libraries. Built for businesses, miners, wallets, and hobbyists
Why bcoin?
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.
Optimized
Engineered from the ground-up to create scalable, flexible, and efficient production-ready systems with unparalleled code readability.
Details ›Secure
Bcoin is consensus conforming and adheres to the strict security standards of the original implementation maintained by Bitcoin Core.
Details ›Advanced
Bcoin can be integrated into almost any desktop or browser application to enable native payments, on both Bitcoin and Bitcoin Cash networks.

Optimized
for Production
Bcoin is the first fullnode 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.
Robust Wallet APIs
Included natively is a REST API, and a legacy JSON RPC API; both let you easily interact and manage large scale wallet systems on multiple blockchains.
Built-in Accounting
Large scale e-commerce company processing many transactions? Online wallet provider? Bcoin has wallet accounting built right in, making user fund management even easier.
Secure,
Written from Scratch
Developing applications that natively utilize a blockchain can be difficult, even for seasoned developers. Bcoin abstracts out the most difficult components of crypto development — allowing you to focus on creating great functionality, with hardened security at its core.
Consensus Tested
Consensus aware, bcoin conforms to all consensus measures present in Satoshi's reference implementation. Bcoin can even be used to mine on the bitcoin mainnet, and has successfully been used to mine blocks as well.
Industry Trusted
Companies like Ripio, Bitpay and Purse have built utilities and tools on bcoin that are now core components of their infrastructure, seeing large-scale daily use by consumers.
The Most Advanced
Fullnode Implementation.
Since its purpose is for production and enterprise, bcoin includes embedded support for various advanced features. With bcoin, companies can quickly begin work on robust, future-ready proof of concepts to be deployed on mainnet.
Advanced Account Management
Bcoin makes managing a large number of user addresses and accounts more seamless. Scale to millions of addresses and manage user funds with ease, without having to worry about key migrations as your business grows.
Event-Based Notifications
Bcoin allows for high-level websocket events for blockchain monitoring and account based events for wallets; allowing for the creation of plugins and utilities that reference the blockchain more easily.

'use strict'; var bcoin = require('bcoin'); var node = new bcoin.fullnode({ network: 'testnet', db: 'memory' }); (async function() { await node.open(); await node.connect(); node.on('connect', function(entry, block) { console.log('%s (%d) added to chain.', entry.rhash(), entry.height); }); node.on('tx', function(tx) { console.log('%s added to mempool.', tx.txid()); }); node.startSync(); })();
Setup your Bcoin Node
Once you have bcoin installed, setting up a node on the bitcoin test network is simple.
Having a node set-up will allow you to more easily test and query the RPC/REST API, and begin monitoring new transactions added to the blockchain/mempool.
