Can there be multiple Hyperledger Fabric CA servers in the same blockchain

Question

I was going through the Hyperledger Fabric CA documentation and was understanding the architecture and the working. One diagram there displayed a cluster of CA servers in the blockchain. I just wanted to know whether it is possible to have/run multiple CA servers(each CA server belonging to a different organization) in the same blockchain. Please help.

Thank you.

Answer 1

Yes, you can run multiple CA servers that belong to different organizations in the same blockchain, provided that the cacerts directory of the MSP directory contains the certificate authority chains of other certificate authorities which represents the roots of trust for the peer.

To do these, you have to first initialize your CA server and after that, you can get the root certificates using the 

fabric-ca-client getcainfo 

command. 

The fabric-ca-client getcainfo command is used to retrieve these certificate chains from other 
Fabric CA server instances.
