By 2026, the Web3 world faces an unavoidable reality—explosive growth in data volume, yet the problem of large file storage remains a stumbling block for the industry. Centralized cloud storage solutions seem cheap but are actually exorbitantly expensive, with privacy risks hanging like a sword overhead. Decentralized players—Filecoin, Arweave—though appealing, come with terrifyingly high costs, slow data recovery, and most importantly, lack programmability.

The native storage protocol Walrus Protocol in the Sui ecosystem changes this situation. Using a 2D erasure coding technology called Red Stuff, it splits large files into fragments for storage, ensuring security with only 4 to 5 times replication factor—traditional solutions require 10 to 20 times. Imagine that—costs are slashed by over 80%. Storing 10GB of data? Just a few cents. Even if 2/3 of the fragments are lost, the system can quickly reconstruct the data, with minimal bandwidth consumption.

But that’s not the most impressive part of Walrus. The real killer feature is **programmable blobs**.

On the Sui chain, blobs are not dead data; they are native objects. You can read, write, control versions, update dynamically, and combine them arbitrarily directly within Move smart contracts. Data transforms from "stored files" into "living assets"—responsive, iterable, bursting with creativity.

Imagine these application scenarios: AI agents pulling datasets in real-time for inference, automatically writing back results to update, forming a complete closed loop—no repeated API calls, efficiency skyrocketing. Game skins automatically change color, upgrade, or even destroy based on player behavior—this isn’t animation effects; it’s real data state changes. Social apps can easily implement "pay to view HD version."
