Core Concepts

This section discusses the core concepts of a Hyperledger Indy Network along with

the consensus protocol used by it. It also serves the example of Network D while

explaining the procedures relating to the network. The core concepts are explained

from Sects. 3.3.1.1–3.3.1.8.

Stewards

Indy is intended to be worked to such an extent that everybody can see the substance

of the blockchain, however, just pre-endorsed members, known as Stewards, are

allowed to take part in the approval interaction.

Stewards can compose the exchange into the Hyperledger Indy record kept up

by Sovrin. Stewards can be a prominent government-claimed organization whose

errand is to run and kept up the Sovrin network. To turn into a Steward, there is an

appropriate onboarding measure characterized by Sovrin. Figure 5 shows the block

diagram of Steards.

Trust Anchor (TA)

Indy Stewards are nodes of the Hyperledger Indy network that have authorizations to

take an interest in the approval interaction. Trust Anchor is the connection between

User and Stewards. TA can be banks, colleges, medical clinics, specialist co-ops,

protection companies. TA acknowledges the solicitation from the client and advances
