After successfully bootstrapping the network, other organizations can join it. Joining the network means joining your ordering nodes to the ordering system channel and fetching or uploading its genesis block.
Info: Starting from Catalyst Blockchain Platform v. 2.3 you can onboard a new organization to the network even if it doesn’t host any ordering node. Please, refer to this section to read how to join a network with an external orderer.
Tip: A consortium defines a set of organizations that can create application channels and join them during creation.
Upon completion of the steps by both organizations, your consenters and peers can be added to application channels (or create application channels if your organization was added to a consortium).
Joining a system channel with an external orderer
You can join a system channel with no ordering nodes deployed by your organization. In this case, you need to ask any orderer organization to send you the link to any consenter from a system channel and add it as an external orderer.
Join a system channel with an external orderer
Create your organization as described in the “Create an Organization” section.
Note that you don’t need to create ordering sets with orderers in this case.
Export the MSP definition.
Share your organization MSP to Organization 1.
Wait until Organization 1 adds you as a partner and shares its MSP definition with you with a link to one of the consenters.
Add Organization 1 as a partner (add its MSP to partners MSPs).
Create an external orderer with the provided link.
Your organization is a part of the blockchain network now.
Meanwhile, Organization 1 (any network member) should perform the following steps:
Add your organization's MSP definition to the partners list. See details here.
Add your organization as an orderer organization. See details here.
Copy an external link from one of the consenters of the system channel and share it with your organization.
