Privacy issues are becoming a core concern for Web3 users. The Walrus project on the Sui chain has made significant explorations to address this need.

From a technical perspective, Walrus's architecture is relatively straightforward—by erasing encoding and using distributed blob storage, data is sharded and stored across decentralized network nodes. This ensures that even if some nodes go offline, data remains recoverable and the system is inherently resistant to censorship. On the DeFi application layer, it supports private transactions, privacy-preserving governance voting, and identity protection during staking and mining, allowing users to participate in dApps without exposing wallet information.

In practical scenarios, this solution has several potential applications. On a personal level, it can be used for privacy wallets and cross-chain transactions; for enterprise-level applications, it includes encrypted data storage; and in a broader sense, it opens up possibilities for metaverse identity authentication. Of course, balancing privacy protection with on-chain transparency remains a challenge—technology can achieve privacy, but whether the ecosystem can operate healthily depends on future developments.

As users' demands for data sovereignty increase, similar privacy infrastructure may become a focal point in the next phase of Web3 infrastructure competition. Walrus's exploration at least shows that someone is working in this direction, making it worth watching.
