Sui has quickly emerged in the public chain sector due to its high throughput and low latency features. One of the most noteworthy supporting infrastructures is storage infrastructure like Walrus.

Its positioning is very clear—it's not just a file storage network, but aims to build a complete decentralized storage economy through the $WAL token. Use cases such as DeFi, privacy transactions, and dApp development can all be built on top of it.

How to understand this from a technical perspective? Walrus uses erasure coding technology to shard data and disperse storage. This brings a benefit: even if some nodes go offline, data remains complete and recoverable. Compared to centralized cloud storage solutions, costs can be several times lower, while also avoiding single point of failure risks and censorship. This is especially attractive for DeFi projects—user asset records, transaction history, and on-chain media content can all be stored without worrying about cloud service providers' attitudes.

The design of the $WAL token is even more worth dissecting. It serves three roles: governance rights (voting on protocol parameters and fee distribution), staking rights (locking $WAL to operate storage nodes and earn network rewards), and value capture (a portion of protocol fees used for buyback and burn or liquidity incentives). This mechanism makes $WAL not just a speculative asset but a rights token contributing to the ecosystem. The formation of a strong security consensus also stems from this staking-reward positive cycle.

In terms of privacy protection, users can enable end-to-end encryption to store sensitive data, maintaining full control over access permissions. This provides strong support for applications requiring data privacy (such as certain DeFi strategies and personal financial records). The entire design concept is: storage infrastructure → token incentives → ecosystem applications → network effects, forming a tightly linked cycle.
