I used to think on chain data was always just tiny notes and pointers. Then I looked at Walrus Protocol and it completely changed how I see it. Walrus actually stores big files like videos, PDFs, and AI datasets by turning them into blobs, splitting them up, and spreading them across many nodes. So if one node drops, I still have my file.
What I like is how Sui fits into this. Smart contracts handle proofs and payments, while Seal lets data stay locked and only released when the rules say it should be. Nothing is handed out early or by accident.
From my view, WAL fees are not about speculation. They are there to keep storage costs predictable and steady over time. That makes the whole system feel more like real infrastructure than an experiment.
