Do you know why Walrus can achieve higher reliability than Filecoin with only 4–5 times redundancy? The secret lies in Red Stuff two-dimensional erasure coding! @Walrus 🦭/acc organizes data into a matrix, applying dual encoding horizontally and vertically, with each node holding a pair of "primary shard + backup shard." Even if 2/3 of the nodes go offline, the original Blob can be reconstructed using just any k shards. This not only saves space but also reduces recovery bandwidth by 90%! This is the engineering aesthetics of decentralized storage. $WAL #walrus
