The Walrus data storage protocol utilizes decentralized storage nodes to manage and store unstructured content and provides the data they store. Here are the main types of nodes in the Walrus protocol: Storage Nodes, Publisher Nodes, and Aggregator Nodes.

Storage Nodes are responsible for storing data and ensuring its availability and integrity.

Publisher Nodes have 3 functions: data uploading and management, metadata handling, and access control.

Aggregator Nodes do data aggregation, load balancing, and data verification.

Blockberry gives access to GraphQL Walrus endpoints received from the 3 types of Walrus nodes through the links in the table below.
