In this era, we are experiencing a surging data revolution. Billions of images, videos, and AI models flood to the cloud every second, only to quietly disappear due to data center failures or regulations. If the internet is compared to a magnificent building, then its supporting foundation—the storage layer—is made of paper. Giants like Amazon S3 and Google Cloud seem solid as a rock, but in reality, they are fragile and exorbitantly expensive. It is in this predicament that Mysten Labs' Walrus emerges like a colossal beast, standing out in the Web3 wave. It is not about patching up existing solutions but about fundamentally redefining the concept of "data permanence."

To understand Walrus, one must first abandon the outdated mindset that "storage = backup." In the Web2 era, storage was a passive leasing model, and early Web3 regarded storage as a burden. Filecoin is impressive, but essentially it is a decentralized warehouse, with complex matchmaking that is a nightmare; Arweave advocates for permanent preservation, but once data reaches PB levels, the redundancy costs are comparable to buying land on the moon. Walrus changes the game. It introduces a powerful tool called Blob—binary data blocks. These data are no longer confined to a single node but are fragmented through an algorithm called Redstuff, dispersing evenly across the entire network of nodes, like DNA strands.
