Decentralized Data Hub (DDHub)

The Decentralized Data Hub (DDHub) is one of the primary technologies underpinning EW Data Exchangearrow-up-right 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 DIDarrow-up-right 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
