Manage orderer

The ordering service node (orderer) acts as a system administrator to manage channel configuration information within the network. It orders transaction blocks generated in the network and delivers them to peer nodes.

Create orderer

You can create an orderer to manage configuration information for channels within the network.

Note

To configure an orderer, you must first create the following items:

  • Certificate Authority (CA): Manages nodes and administrator accounts belonging to the organization. For details, see Create CA.
  • Membership Service Provider (MSP): Grants and manages permissions for the organization. For details, see Create MSP.

To create an orderer:

  1. Navigate to i_menu > Services > Blockchain > Blockchain Service > Nodes in the VPC environment of the NAVER Cloud Platform console.
  2. In the Network name dropdown list, click the network to create an orderer.
  3. Click the [Orderers] tab and click [Create orderer].
  4. Specify the orderer creation information and click [Create].
    • The orderer is created.
Note
  • Select one of the orderer-type IDs registered in the network CA as the CA user ID (orderer). For details, see Manage CA user ID.
  • You can select either single (raft 1) or multiple (raft 5) for the orderer type. This creates 1 or 5 orderer nodes, respectively. Use multiple (raft 5) for production environments that require high availability (recommended).
  • Configuring multiple (raft 5) as the orderer type creates 5 orderer nodes. Check the available resources in your Kubernetes cluster beforehand.
  • Click Deploy network and specify a Kubernetes cluster node pool to deploy blockchain nodes to the selected node pool. The node affinity labels configured for Ncloud Kubernetes Service appear in the list, and you can specify up to 3 labels.
