Bch Lib

NPM Package Build Status Coverage Status

A pure and powerful JavaScript Bitcoin Cash library.


This repository was created by copy forking bitcore-lib 09b97ac.


Bitcoin Cash is a powerful peer-to-peer platform for the next generation of financial technology. The decentralized nature of the Bitcoin Cash network allows for highly resilient bitcoin cash infrastructure, and the developer community needs reliable, open-source tools to implement bitcoin cash apps and services.

Bitcoin Cash vs. Bitcoin

Bitcoin Cash uses an optional alternate address format called "cashaddr". It also has several additional changes to the script interpreter that allow the basics for smart contracts.
