Blockchain technology used in medicine. A brief survey

Blockchain is the technology that allows people to make transactions without intermediaries. Bitcoin was the first cryptocurrency launched. Cryptocurrencies are digital tokens that can be used for transactions. They use cryptography to establish their authenticity and are not linked to a central authority. Blockchain has many advantages for the healthcare industry and can be used in various fields such as: implementation and improvement of electronic patient records, in clinical trials, neuroscience, pharmaceutical industry and research. Its security can help to improve the confidentiality of patient data and can also help secure the supply chain of medicines. The security and transparency of the blockchain will play a crucial role in the medical industry. This will allow companies to register their products and conduct secure transactions. QR codes can also be placed on the back of medicine containers to help customers identify the authenticity of the products they purchase. The exchange of health information through the blockchain will also have various challenges, such as maintaining the confidentiality of patient data. At the same time, due to the different regulations in different countries, it can be difficult to establish an efficient and secure exchange. Unlike other cryptocurrencies, blockchains are usually immutable, which means that the data added in the chain will always remain. This eliminates the risk of data loss.
