The DomaniSystems' Blockchain Intellectual Property (IP) Library conforms to the architecture illustrated here in this three node example. 

 

The user interface is a web browser based GUI that is the front-end  of a Decentralized Application (DApp) written in JavaScript.  The DApp can be a simple program that accepts and provides basic communications with the user or it can be very complex with interactions with multiple databases.

 

The DApp interfaces with the Smart Contract that is running on the Blockchain node.  The Blockchain network can be public Ethereum,  Hyperledger or a customer's  private network.
