Blockchain technology revolutionizes gene data ownership in medical research, with platforms like Genomes.io leading the charge. By leveraging decentralized ledgers, individuals gain control over their genomic data, ensuring privacy and security. Genomes.io’s DNA Vault empowers users to store, manage, and selectively share their genetic information with researchers, fostering personalized medicine while maintaining ownership. Smart contracts and encryption ensure transparent, tamper-proof access logs, addressing ethical concerns around data misuse. This model incentivizes data sharing for scientific breakthroughs, like disease prediction and drug development, without compromising individual rights. As genomic data grows, blockchain offers a scalable solution to balance privacy, research, and ownership, paving the way for a future where patients are true stewards of their genetic blueprint.
