#walrus $WAL At the heart of Walrus lies Red Stuff, a groundbreaking two-dimensional erasure coding protocol that sets it apart in the decentralized storage arena. Developed by the Mysten Labs team behind Sui, Red Stuff addresses core limitations of prior systems: high redundancy costs, slow recovery, and vulnerability to correlated failures.
Erasure coding basics involve splitting data into fragments, adding parity pieces, and allowing reconstruction even if some pieces are lost. Classic 1D schemes (Reed-Solomon) work well for small failures but struggle with efficiency at scale. Red Stuff introduces a 2D grid approach: data is arranged in rows and columns, with independent erasure codes applied horizontally and vertically. @Walrus 🦭/acc This creates overlapping redundancy layers — if an entire row or column fails (e.g., due to a regional outage or malicious nodes), the orthogonal coding still enables recovery.
