Identity Classification
The default MSP implementation allows organizations to further classify identities into clients, admins, peers, and orderers based on the OUs of their x509 certificates.
An identity should be classified as a client if it transacts on the network.
An identity should be classified as an admin if it handles administrative tasks such as joining a peer to a channel or signing a channel configuration update transaction.
An identity should be classified as a peer if it endorses or commits transactions.
An identity should be classified as an orderer if belongs to an ordering node.
