     6  Hyperledger Fabric allows for different organizations and participants
     7  in a common network to utilize their own certificate authority, and as a
     8  byproduct, implement varying cryptographic algorithms for
     9  signing/verifying/identity attestation. This is done through an MSP
    10  process running on both the ordering service and channel levels.

    12  Membership service provider (MSP): A set of cryptographic mechanisms and
    13  protocols for issuing and validating certificates and identities
    14  throughout the blockchain network. Identities issued in the scope of a
    15  membership service provider can be evaluated within that membership
    16  service provider’s rules validation policies.
