“At BitPay, we believe that developers contemplating new Bitcoin projects should not have to resort to using proprietary APIs hosted on services running closed software,” the company wrote on their blog. “To encourage more developers to build software that interfaces directly with the real bitcoin network, we are launching Bitcore.”
From the post:
Like several other companies and projects, BitPay created an internal fork of Stefan Thomas’ bitcoinjs project. We’ve decided to open source that fork and put some effort into ensuring that it had sufficient capability out of the box to attract developers to start using it. We felt we needed an initial project that uses the bitcore stack to ensure it was indeed useful for real projects from day 1. That project is called Insight and is a simple block chain explorer.
