Walrus, a storage protocol on the Sui ecosystem, has been quite interesting lately. Its goal is to provide a privacy-first, truly decentralized storage option—using the WAL token to incentivize the entire network operation.

Let's start with the core technical solution. Walrus uses erasure coding to split files into multiple encoded fragments, adding redundant data and dispersing storage. This way, even if some nodes go offline or are attacked, the remaining fragments can quickly reconstruct the original data. It sounds similar to Reed-Solomon codes, but Walrus is optimized for blockchain features. Coupled with Sui's parallel processing, it can achieve sub-second data retrieval.

Blob storage is another highlight. Ordinary blockchains are limited by block size and can't store large files. Walrus uses Blob to store videos, datasets, enterprise archives, and other large data collections in blocks, completely solving this bottleneck. According to testing data, uploading a 1GB file takes only one-third of the time compared to traditional IPFS solutions, with over 80% cost savings. This means better solutions for NFT storage, decentralized CDN, and enterprise backup systems.

In terms of privacy, Walrus integrates privacy black technologies like zero-knowledge proofs and ring signatures, enabling truly private transactions and data access. Want a storage solution that is cheap, secure, and resistant to censorship? Walrus is worth paying attention to.
