Long-term health data is often locked by centralized institutions such as hospitals and physical examination centers, leaving users vulnerable to privacy leaks and wasting the commercial value of their data. This situation is being broken.

Built on the Walrus Protocol, the decentralized health data platform truly returns data ownership to users. Imagine this scenario: your sensitive information such as BMI, hemoglobin test results, and genetic sequences are stored with end-to-end encryption using Walrus's Seal privacy feature. Who can see your data? It’s entirely up to you.

Need your primary care doctor to access your complete health records long-term? Authorization granted. Only want the insurance company to see test results for a specific period for premium calculation? Then only share that part. Want to contribute anonymous data to research institutions in exchange for rewards? That’s also possible. How data is shared and where its value flows are all your choices.

Technical breakthroughs make all this possible. Red-Stuff’s 2D erasure coding technology reduces storage costs by over 98%, so users no longer have to worry about the expenses of long-term storage of massive amounts of data. The emergence of this infrastructure opens up the imagination for large-scale deployment of decentralized applications—starting with medical data, the model of privacy protection and data autonomy is expected to expand into more fields.
