Web3 can revolutionize healthcare access through decentralized personal health records (dPHRs) on the blockchain. By giving individuals ownership and control over their medical data, Web3 enables secure sharing across providers, improves decision-making, and reduces reliance on fragmented systems. This is especially valuable in low-resource or developing regions, where centralized infrastructure is limited. Globally, it promotes health data democratization, patient autonomy, and cross-border collaboration—making healthcare more transparent, equitable, and efficient.
