If blockchain is applied to healthcare smartly, it can really help https://weelorum.com/blog/blockchain-in-healthcare-how-the-technology-is-app... — by storing medical records in a decentralized, immutable ledger, patients get full control over who sees their data and when, which reduces the risk of data leaks or unauthorized changes. It also makes it easier for different clinics or doctors (maybe even in different cities) to access a patient’s full history — which improves diagnoses accuracy, avoids repeat tests, and speeds up care. Beyond that, blockchain can track drugs and medical supplies through the supply chain so it becomes harder for counterfeit medicines to slip through, and can automate things like insurance claims or consent management with self-executing contracts (smart contracts), cutting red tape and mistakes. In short: used right — blockchain can make healthcare safer, more transparent, more efficient — but it requires good design and respect for privacy from the start.
