I don't really want to start with the definition of Walrus, because that easily falls into the routine of popular science. Let's approach it from a more practical perspective—when I look at projects, I have a habit called the "Counterintuitive Checklist." For projects that seem grandiose, I tend to lower my expectations; for those that appear ordinary but are actually doing real work, I’ll spend more effort studying them. Walrus is a typical example of that: boring, but potentially really useful.

My own standard is very clear: I don't trust projects that rely on a "one-sentence narrative." Especially for infrastructure-type things, if the entire value proposition is supported by just one story—like "all data will eventually be on-chain"—I basically won't bet on it. The inertia of the real world is too strong. Truly sustainable infrastructure never relies on inspiring slogans, but on a bunch of unsexy but practical things: whether developers find it easy to use, whether costs are predictable, whether data can be stored reliably, whether the service is dependable. These are the core.

The reason Walrus makes me want to take a closer look is, frankly, because its approach is more pragmatic. It positions itself as a "data layer patch" for on-chain applications, which is a very interesting angle. Anyone who has worked on on-chain products knows this dilemma well: smart contracts are extremely costly and capacity-constrained, and are simply not suitable for storing large files; but what users need—images, videos, proofs, content, AI models—these can’t just be casually shoved onto the chain.

The current industry approaches generally fall into two paths. One is to directly use centralized cloud services—convenient, yes, but somewhat contrary to the original intention of decentralization. The other is to assemble solutions like IPFS, which retain some decentralization features, but at the cost of engineering complexity and system stability that can cause headaches for years. Both approaches are usable, but both feel a bit awkward.
