Walrus Protocol is a decentralized data storage network built on the Sui blockchain. It is designed to store large files like videos, images, NFTs, and AI datasets in a secure, scalable, and low-cost way. Instead of relying on centralized servers, Walrus distributes data across independent nodes using advanced erasure coding, ensuring high availability even if some nodes fail. The WAL token is used for storage payments, rewards, and future governance, making Walrus a key infrastructure layer for Web3 and AI applications.
