<p>Electronic health records (EHR) are presented as a digitized solution to store clinical data of patients and their medical history. However, concerns are raised about the security and privacy of this information. Through blockchain technology, these concerns can be addressed by creating secure, decentralized systems for storing and sharing medical data. The distribution, decentralization, immutability and traceability characteristics of data stored on the blockchain ensure that the data remains reliable and secure.</p>
<p>A review of the scientific literature in the field of storing medical records in the Blockchain is presented to verify the applications of this technology in critical systems such as those that manage people's medical information.</p>
