A blockchain network is a consortium consisting of multiple organizations.

You can create a consortium in one of the following ways:

  • Quick mode: You only need to specify the required information, and Alibaba Cloud BaaS will automatically perform operations to create a complete blockchain network. These operations include creating a consortium, creating organizations, and inviting groups to join a consortium or a channel. For more information, see Quick start.
