DDHub Message Broker

Overview

DDHub Message Broker is a component that primarily provides message routing, persisting, and delivery for a seamless data exchange between participants within an energy market or supply chain.

The message broker promotes sovereignty of participants by:

• The broker does not have authority or logic which assumes the power of the participants

• No one except the participant themselves can govern data exchange channels and verify messages

• Encryption/decryption, signature validation, authorization, etc must be done under the participants domain (Client Gateway)

Below are the Message Broker components which need to be hosted to deploy a Decentralized Data Hub:

• Message Broker App

• NATS Jetstream and Jetstream Store to store small data messages (small messages up to 2 MB) and channel configurations

• Azure Blob (or other large file) Store for large data messages and delimited files converted into blobs, as well as file metadata

• RDBMS for message topic and schema management
