There are different sets of libraries in https://github.com/bitpay/bitcore
- Node - A full node with extended capabilities using Bitcoin Core (what is the role of this node ? As i can see this code in node js . Is this means that bitpay has implemented the bitcoin core in node js ? )
- Insight API - A blockchain explorer HTTP API
- Insight UI - A blockchain explorer web user interface
- Wallet Service - A multisig HD service for wallets
- Wallet Client - A client for the wallet service
How do these different libraries interact with the Bitcoin blockchain?
Anyone explain the flow in steps will be highly appreciated.
