Initialization

The algod node initialization refers to the process by which the Algorand node daemon starts up and activates all its internal services.

This process is guided by a configuration file.

The main configuration switch, EnableFollowMode, determines the node’s operational mode:

• If set to false, the node runs as Full Node,

• If set to true, the node runs as Follower Node.

Once the node is initialized based on the configuration, the system starts up all services, allowing them to begin functioning.

The diagram below illustrates this initialization sequence, highlighting the key role played by the Algorand node daemon algod.

    Node->>-Server: returns Node
