# Nodes

In Angus, nodes refer to the fundamental components of the Hyperledger Fabric blockchain network responsible for processing, validating, and managing transactions.These network nodes serve different roles and can be categorized into multiple types:

Ordering Nodes: These nodes are responsible for ordering transactions, packaging them into blocks, and distributing them to peers. It ensures a consistent and secure transaction flow.
Peer Nodes: These nodes are responsible for storing and validating ledger data, participating in consensus, and executing chaincode applications.
CA Nodes: These nodes are responsible for managing the lifecycle of identities and certificates within the network.
