Blockchain is an advanced database mechanism that is used to record, preserve and exchange patient data across hospitals, diagnostic laboratories, pharmacies and physicians. Data is stored securely, so that the record cannot be altered.  

A blockchain database stores data in blocks that are linked together in a chain. In short, blockchain can improve digital health by making it simpler to share data securely, with a patient agreement, across incredibly dispersed healthcare system
