The basic purpose of a complete data storage protocol is to let a writer store data on a network of storage nodes and allow readers to reliably read that data even if the network is slow, some nodes fail, or some nodes act in a Byzantine (malicious) way. The system operates with (n = 3f + 1) nodes, where up to (f) nodes may be malicious, yet availability and consistency are still maintained. If the writer is honest, every honest storage node stores a shard (a part) of the data. These shards are designed so that combining a limited number of parts recovers the full data, so full replication is unnecessary and storage costs are reduced. The protocol ensures that if two honest readers access the same data, they always get the same result—either both successfully read the data or both fail. Once data is successfully stored, any honest reader can read it. This ACDS model is adapted within the Walrus protocol using epoch-based, dynamic storage committees where nodes rotate, making the system more secure, scalable, and suitable for real-world decentralized environments.
