Blockchain technology offers great potential in the healthcare sector and is therefore receiving more and more attention. The complexity of our system makes it difficult to digitize processes and the blockchain could help. It offers easier organization, more transparency and still guarantees data protection and control over the patients’ own data. The blockchain also speaks for itself in the field of research. Algorithms can check and evaluate massive amounts of data, because “machine learning” and the artificial intelligence behind it enable precise and more reliable diagnoses and research results.
