Understanding Various Certificates in Hyperledger fabric

Question

Hello I am tryin to use hyperledger fabric for a block chain implementation. I did the first-network demo and found lot of certificates in it. I have tried arranging them hierar

Answer 1

First of all thanks for creating the tree for the same.

I am a beginner in the hyperledger but what i understand from the hyperledger document that each Organization requires a unique root certificate (ca-cert), that binds specific components (peers and orderers) to that organization. Transactions and communications within Fabric are signed by an entity's private key (keystore), and then verified by means of a public key (signcerts).

As different organization also required to communicate or share their ledger so there is need of CA or MSP on organization level. Within each organization we can have multiple peers so we need certification for these peers too. Even peers from different organizations can join each other so signcerts(for authenticating) and TLScerts(for a secure handshake).

To have a look how these are generate i suggest you to Manually generate the artifacts

and see the different certs in the folders inside as you created them.
