Recently, Walrus (WAL) has been trending in the Web3 circle, but many people still don't clearly understand what it actually is. Instead of being overwhelmed by a bunch of technical jargon, let's clarify it straightforwardly.

**Background is Key**

Walrus is the direct offspring of the Sui public chain, developed by Mysten Labs. To put it more vividly—if Sui is a smartphone, Walrus is its built-in cloud storage system. This positioning determines its role within the ecosystem.

**Where Is Its Core Competitiveness**

The storage cost issue faced by public chains is a longstanding challenge. Storing a single image on Ethereum can cost hundreds of dollars, which is obviously unreasonable. Although Filecoin aims to solve this problem, its speed is too slow, limiting practical applications. Walrus employs a new technology called "Red Stuff," which directly reduces storage costs to the minimum, with speeds fast enough to support video playback—this is a qualitative breakthrough.

**Why Focus on It Now**

The Sui public chain has maintained popularity over the past two years, with a continuously exploding ecosystem—games, NFTs, various DApps emerging one after another. These applications generate massive amounts of data daily, and storage needs will inevitably grow. All this data will eventually be directed to Walrus, similar to controlling a key piece of infrastructure. From an investment perspective, WAL is currently priced around 0.158, and the project is still in its early development stage, leaving plenty of room for growth. In simple terms, this is the foundational layer project of the Sui ecosystem, increasingly resembling a business that sells shovels.
