I often see creators complaining about a pain point in Web3: data storage has become a major challenge when developing NFT projects or on-chain games.

The previous approaches were basically two, and neither was satisfactory. One was to put everything on the public chain, but the high gas fees and storage costs made people feel it's unaffordable—it's like piling up clutter in a land of limited space, wasting money. The other was to directly upload data to centralized servers like Amazon AWS, which seems convenient on the surface, but the problem is: if these companies experience a power outage or shut down, your carefully crafted NFT and game data are gone, and your efforts are lost.

Now, Walrus has changed this situation. From a different perspective, it’s like a Costco warehouse service in the Web3 world. The core mechanism is simple: break your data into small pieces and store them across various nodes worldwide. The benefits are obvious—much cheaper rent and complete decentralization. Even if some nodes in a certain region encounter issues, data fragments from other locations are enough to reconstruct the entire file, greatly enhancing security and availability.

Why is Walrus so critical to the SUI ecosystem? Frankly, without an affordable and easy-to-use data storage solution, Web3 applications can't innovate beyond a certain point—they'll just spin in circles with word games. The emergence of Walrus fills this gap, providing developers with the fundamental infrastructure support to build and scale their applications.
