Walrus is a decentralized storage network that is a breakthrough in this space and is spearheaded by Mysten Labs (the brains behind Sui blockchain). This is now furthered by the Walrus Foundation. Walrus is a paradigm-shifting technology that changes how we deal with binary large objects in a world of Web3 and abolishes the traditional trade-offs that come with decentralized storage.
The game-change is the invention of “Red Stuff”, an efficient 2D erasure code. By comparison to full replication (exacting 25x+ for high security) or traditional Reed-Solomon codes (3x but costly with linear recovery complexity O(|blob|)), Red Stuff Provides Byzantine fault-tolerance with merely 4.5x replication overhead and facilitates self-healing recovery. The retrieval of missing “slivers” requires bandwidth linear in the missing data itself (O(|blob|/n)), making this approach highly scalable even for 500+ participants.
This is accomplished via clever 2D coding, where the blob is represented as a matrix, with the addition of Repair symbols in both the rows and columns, establishing primary and secondary slices per node. Authenticated Vector Commitments enable security against malicious Behaviour, as well as the addition of the first asynchronous Storage challenges.
Walrus has a new multi-stage era switching mechanism that scales permissionless node rotations seamlessly

Walrus est un réseau de stockage décentralisé qui constitue une avancée majeure dans ce domaine et qui est porté par Mysten Labs (les créateurs de la blockchain Sui). Ce projet est aujourd'hui renforcé par la Walrus Foundation. Walrus est une technologie révolutionnaire qui transforme la manière dont nous gérons les objets binaires volumineux dans un monde Web3 et élimine les compromis traditionnels liés au stockage décentralisé.
Le changement majeur réside dans l'invention du « Red Stuff », un code d'effacement 2D efficace. Contrairement à la réplication complète (exigeant 25 fois ou plus pour une sécurité élevée) ou aux codes Reed-Solomon traditionnels (3 fois mais coûteux avec une complexité de récupération linéaire O(|blob|)), Red Stuff offre une tolérance aux pannes Byzantines avec un surcoût de réplication réduit à 4,5 fois seulement, tout en permettant une récupération autonome. La récupération des « morceaux » manquants nécessite une bande passante linéaire par rapport aux données manquantes elles-mêmes (O(|blob|/n)), ce qui rend cette approche extrêmement scalable même pour plus de 500 participants.
