Yes—through attestations and zero-knowledge proofs, systems can verify claims while data stays local, making history provable without exposing or transferring underlying information.

A while ago, I tried to register for a new service, and the first requirement was to prove that I have a real digital activity. It wasn't something complicated, just a confirmation that I had used similar services before. The strange thing is that I already have this proof, but it exists within another platform. I couldn't transfer it and I couldn't prove it. It's as if my digital history is trapped within every application I've used before, and every time I start from scratch, I feel that the internet remembers everything except when I need to prove it.
