Decentralized Data Hub (DDHub)

The Decentralized Data Hub (DDHub) is one of the primary technologies underpinning EW Data Exchange solutions. The DDHub Environment is composed of multiple DDHub Messaging Client Nodes interacting with each other through the DDHub Message Broker.

  • Each node (or group of nodes) in the Message Broker cluster is identified with a unique DID and must be issued with a DDHub Messaging Client role

  • Each node contains an IAM Client that ensures legitimacy of users interacting within the messaging cluster by checking their identities, and issued role or set of roles\

  • The IAM Client and DIDs provide a layer of protection against unauthorized access to DDHub functionalities

  • Data exchanged within the cluster is secured in transit with mTLS
