Bitcore Library

A pure and powerful JavaScript Bitcoin library providing core Bitcoin primitives such as addresses, transactions, HD keys (BIP32), and message signing. Current stable version is 10.10.7. Maintained as part of the Bitcore ecosystem by BitPay/Bitcore, it is primarily used for building Bitcoin-related Node.js applications. It offers a comprehensive API for creating and parsing transactions, managing keys, and interacting with the Bitcoin network. Key differentiators include full support for BIP21, BIP32, BIP37, and BIP69, and its integration with the Bitcore full node and Insight block explorer.
