DDHub Message Broker

PreviousDecentralized Data Hub (DDHub)NextDDHub Client Gateway

Last updated 1 year ago

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 ()

DDHub Message Broker Component Diagram

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
