Looking at the development of Web3 infrastructure, there's a question that has been circling in my mind: blockchain is no longer just a simple ledger; it has evolved into a full-stack network. What does this bring? A surge in demand.

Everyone is looking for a storage solution—cheap like cloud services yet maintaining decentralization. Hash files for AI models, historical data for DeFi, core information for various on-chain applications—storing only hashes on-chain is simply not enough. We need truly "programmable data." That's why projects like Walrus have emerged.

But here’s a key question: Is Walrus really a silver bullet? Not necessarily. It’s not万能, and there are a bunch of prerequisites behind it.

First, we need to change our mindset— not all data should be permanently stored on-chain. Arweave is about a "one-time payment, forever preserved" story, which sounds perfect. But Walrus takes a different approach, more like real-world business logic: a leasing model. You pay for as long as you need storage, renew periodically, and scale on demand.

This determines whether the Walrus model can work—users must accept this "pay to renew" paradigm. If you want to leave humanity a digital monument that never needs maintenance, Walrus might not be the first choice. But if your goal is to solve current practical problems—such as data storage for DeFi applications, hosting NFT metadata, or managing AI model versions—this flexible, on-demand approach becomes much more interesting.
