Blockchain can streamline medical data sharing by enabling secure, permissioned access while preserving patient privacy. Zero-knowledge proofs and homomorphic encryption allow researchers to verify and analyze encrypted data without exposing sensitive details. Patients retain control over who accesses their information and for what purpose, with every request logged immutably on-chain. This balance of confidentiality and transparency accelerates collaborative research and personalized medicine without compromising data security.
