Red Stuff is the core innovation behind Walrus. Instead of full replication (25x copies) or traditional Reed-Solomon encoding, Red Stuff uses a novel two-dimensional erasure coding design. This allows Walrus to achieve strong security with only ~4.5x replication while enabling self-healing recovery that scales with lost data, not total size. Unlike Reed-Solomon, it works safely in asynchronous networks and supports real storage challenges.
