Blockchain technology has transformed the way of information stored and secured over cloud servers. It provides a transparent and tamper-proof ledger system for transactions in optimized time frame hence serving as the foundation for cryptocurrencies such as bitcoin, but its applications have now extended to healthcare data privacy. The mining process is an essential part of blockchain technology, which ensures validity and immutability of data. The primary objective of present study is to create blockchain-based framework for managing patient medical record to prevent unauthorised access and maintain data integrity. It deals with mining of blocks in a blockchain to securely store patient medical information.

The presented methodology implements a blockchain based approach, which uses Python and Flask for blocks generation, mining and verification, with API testing through Postman. In the present paper, the record of each patient is securely mined into block containing patient name, ID, registration number and cryptographic hashes to ensure immutability. The results show that the system effectively mines patient records while maintaining chain integrity and validity, as validated by simulated mining and retrieval operations. The article not only gives a theoretical view of mining but also includes hands-on experience, users may have a better understanding of the fundamentals process by mining blocks, making the concepts more practical and interesting for the users.
