This principle is at the foundation of creating a permissioned blockchain. Instead of allowing any entity to download software and connect to the network, network members must agree upon a policy to admit new members (e.g., by majority vote), which is then enforced by Hyperledger Fabric. Upon a successful vote, the digital credentials of a new member can be added to an existing network.
