Blockchain technology offers a safe and decentralized network for protecting medical records, tackling issues like confidentiality and data accuracy. With the healthcare sector's growing dependence on digital data, the handling and sharing of patient data could be revolutionized by blockchain technology. It functions as a distributed ledger across a computer network, dispersing patient data among nodes instead of storing it centrally. Strong protection against manipulation and unauthorized access is provided by the immutable chain that is created when each data block is cryptographically connected to the one before it.
