Which of the following is the identity solution in Hyperledger Fabric?

In Hyperledger Fabric, the identity solution that manages user identities and authenticates

participants on the network is facilitated by Membership Service Providers (MSPs). MSPs are crucial

for defining the rules by which identities are validated, authenticated, and allowed access to the

network. MSPs handle the issuance of certificates and define the roles and permissions associated

with participant identities, enabling permissioned interactions on the blockchain. This differs from

Hyperledger Fabric CA, which primarily issues and revokes certificates as part of identity

management but is used in conjunction with MSPs to provide comprehensive identity solutions

within the network​​.
