When Camille Parker was hospitalized for a routine surgery, she noticed something odd — none of her doctors had full access to her medical history. “They kept asking me the same questions, over and over,” she says. “It was frustrating and, honestly, a little scary.”
That encounter inspired software developer Camille to investigate how blockchain technology can address some of the most important problems facing healthcare, particularly with relation to data security and access.
Blockchain, the technology behind cryptocurrencies like Bitcoin, is essentially a decentralized digital ledger. In healthcare, it can be used to store patient records securely and give authorized providers instant access to critical data — all without compromising privacy.
“Right now, most health records are stored in siloed systems,” explains Dr. Nora Lin, a healthcare IT consultant. “Blockchain offers the possibility of a unified, tamper-proof, and patient-controlled data system.”
Camille has since joined a startup developing a blockchain-based platform that allows patients to share their medical records with providers on a need-to-know basis. “You hold the key to your own data,” she explains. “It’s encrypted, decentralized, and only accessible when you approve it.”

Beyond data sharing, blockchain is also being explored for use in drug supply chains, clinical trials, and even health insurance claims — reducing fraud and increasing transparency.
Still, challenges remain. Blockchain requires significant infrastructure, regulatory guidance, and industry cooperation to become mainstream. But for advocates like Camille, the potential is worth the effort.
“Imagine a world where you go to a doctor anywhere in the world and they instantly have access to your verified health history,” she says. “That’s not science fiction — it’s what blockchain can make possible.”
