That’s a neat idea—blockchain could make the records tamper‑proof and give everyone a single source of truth. I’d want to keep the interface super simple so the people we’re caring for can actually use it, and make sure we’re still protecting their privacy. Let’s sketch out a few user scenarios and see where it fits best.

Sounds solid, and each one keeps the tech low‑friction for the people who actually need it. I like the “permission ticket” idea—makes sure the doc only sees what’s relevant, and it’s a small win for privacy. The baby log could even help parents feel less overwhelmed; just a quick scan and they get a real‑time pulse. For the senior reminder card, I’d add a tiny touch of humor—maybe a sticker that says “Did you remember?”—to make the reminder feel less like a check‑in. All in all, it feels doable, but we’ll need to test the interface with real users to catch any bumps before we roll it out.
