Protocol-Level Innovations: RedStuff Erasure Coding and Efficient Recovery
At a technical level, Walrus incorporates advanced decentralized storage mechanisms that go beyond typical replication or simple erasure coding. Research on Walrus’s underlying protocols — such as the RedStuff two-dimensional erasure coding scheme — shows how the network balances replication overhead, data integrity, and recovery efficiency even under node churn. These innovations enable Walrus to sustain data availability with significantly lower overhead than naive replication while also supporting efficient self-healing and security guarantees in an asynchronous network setting, which is crucial for decentralized applications that cannot tolerate data loss or prolonged unavailability.
