A JavaScript and C/C++ implementation of the Bitcoin protocol for Node.js, supporting full nodes, SPV, wallets, and mining.
Bcoin is an alternative implementation of the Bitcoin protocol, written in JavaScript and C/C++ for Node.js. It provides a comprehensive suite of tools for running full nodes, SPV nodes, wallets, mining backends, and layer 2 solutions like the Lightning Network, serving as a production-ready backend for Bitcoin applications.
Developers and organizations building Bitcoin-based applications, including exchanges, wallets, mining pools, or layer 2 protocols, who need a reliable, modular, and well-tested JavaScript library.
Bcoin offers a fully tested, consensus-aware implementation that is modular and production-proven, enabling developers to build custom Bitcoin solutions without relying on the reference implementation, with support for diverse use cases from full validation to lightweight clients.
Javascript bitcoin library for node.js and browsers
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Used by Purse.io in production, demonstrating real-world reliability and security for Bitcoin applications, as noted in the README.
Supports full nodes, SPV, wallets, mining, and layer 2 protocols like Lightning, offering a versatile toolkit for diverse Bitcoin use cases.
Designed with modularity in mind, allowing developers to pick components like the wallet backend independently for custom solutions.
High code coverage and continuous integration ensure adherence to Bitcoin consensus rules, as shown by build status and coverage badges.
Requires npm rebuild for C/C++ components, which can lead to setup failures on systems without proper build tools or cause version conflicts.
Being written in JavaScript, it may not match the raw performance of C++ implementations like Bitcoin Core for intensive tasks such as block validation.
Tied to Node.js, limiting deployment in environments that prefer other runtimes without significant workarounds or rewrites.
