Have you ever thought about it? Three years of smartwatch data—heart rate, sleep, exercise tracks—are now sleeping in the servers of a certain tech company, and you have no say in it. These valuable biological features generate value for them every day, while you get nothing.

Here's a different approach: use a decentralized network to store your health data. When medical research institutions need large-scale anonymous data for clinical analysis, they can request access permissions. What's the key? The data is analyzed inside an encrypted black box, and they can only see the statistical summary results, never tracing back to who the original data belongs to.

Your data always remains in your hands. Research institutions get the research material they need. You receive compensation. Privacy protection, data rights confirmation, value circulation—achieving all three goals simultaneously. This is the real-world application of privacy computing in Web3.
