Imagine: one day, your entire conversation history with AI, all generated content, and accumulated personal preferences suddenly disappear. This is not science fiction; it’s already happening. Large tech companies, in the name of compliance and cost reduction, are mass deleting historical data. And what about us users? We’re like goldfish on the internet, with a memory span of only 7 seconds.

The root cause lies in centralization. Your carefully crafted AI assistant, which knows all your habits and the countless conversations you’ve co-created—these can only exist on a single company's servers. They can vanish at any moment due to a policy update or a system migration. You think you own these "digital memories," but in reality, you’re just renting a system that can forget.

Is there a solution? Decentralized storage protocols are trying to change all this. Projects like Walrus, for example, are reclaiming the "memory rights" of data from a single company. The core technology is erasure coding—your data is split, encrypted, and then dispersed across thousands of anonymous nodes worldwide.

What does this mean? No single central server can be attacked, and no company can delete your data with a single command. To completely destroy this memory, one would have to simultaneously damage most of the internet’s infrastructure. This kind of "censorship resistance" is, to some extent, the last bastion of individual sovereignty in the digital age.
