NoteOne Fabric blockchain network is composed of 1 consortium instance + N organization instances, N>=1. The number of organization instances N is determined by the number of business participants and whether there is an exclusive requirement. If a participant needs exclusive blockchain node and ledger, as well as chaincode deployment, blockchain user creation and other management functions, the participant needs to create a separate organization instance. An organization instance can be shared if the participants has no exclusive requirement. Consortium instance and organization instances can be purchased and created by a single cloud account or by different cloud accounts.
