Web3 storage is becoming increasingly crowded, but what makes Walrus Protocol stand out in the SUI ecosystem? Let's break it down into three core aspects.

First, technology. Conventional decentralized storage solutions rely on simply duplicating data to ensure security through redundancy. Walrus uses erasure coding, splitting data into multiple fragments with added checksum verification, requiring only 4 to 5 times replication to achieve high availability. In other words, even if 2/3 of the nodes go offline, data can still be fully reconstructed. This approach directly cuts costs—storage expenses are kept around $50/TB/year. Filecoin is more than three times as expensive, and Arweave is even more costly, nearly 100 times higher. This is the first time decentralized storage prices have been brought to a level competitive with centralized cloud services.

Next, ecosystem stickiness. Walrus maps storage objects directly to on-chain assets, allowing developers to dynamically manage data through smart contracts. Need to modify NFT metadata? Cross-platform reuse of game equipment? All of this can be seamlessly integrated on SUI. This deep binding transforms storage from an isolated infrastructure into an integral part of the ecosystem, providing developers with a more flexible toolbox for building applications across the entire SUI chain.
