Blockchain application case 1 - health care energy industry

Time : 06/02/2022 Author : bxmckz Click : + -
        Blockchain technology can be used in various application scenarios. It should be noted that bitcoin is not equal to blockchain. On the contrary, it is one of the most successful applications of blockchain technology. Bitcoin is a cryptocurrency that is traded through an open, public and anonymous blockchain network. Subsequently, people realized that the technology could be applied in different fields, such as health care, voting, identity management, governance, supply chain, energy, etc. In addition, some experts also predict that blockchain may affect the digital field similar to the Internet. When the Internet first appeared, people did not know how it would change our lives. No one knows that the invention of the Internet will change the world, from smart phones and text messages to real-time video communication with relatives, as well as video conferences or live broadcasts.
 
        At present, we are in the early stage of the blockchain, and there are still many potentials that have not been released. The following figure represents some application fields of blockchain proposed by various experts. Health care distributed ledger technology has the potential to improve medical services. Blockchain can be used for drug traceability and patient data management. Counterfeit drugs are a major problem in the pharmaceutical industry. According to the report of the health research funding organization, 10% to 30% of the drugs sold in developing countries are related to counterfeit drugs. According to the World Health Organization, 16% of the ingredients in counterfeit drugs are wrong, while 17% of the counterfeit ingredients are inaccurate. Therefore, these drugs may not be able to treat the disease, but may cause side effects that may lead to death, and thus may endanger the patient's life.
 
        From the perspective of economics, the annual loss caused by counterfeit drugs to European pharmaceutical organizations is 10.2 billion euros. Blockchain can be used as a solution to this problem, because all transactions added to the distributed ledger are immutable and have digital time stamps, so that products can be tracked and information tampering can be prevented. In addition, managing the integrity of patient data is one of the major issues in the healthcare industry. Each patient's physical condition is different, so the treatment strategy for common diseases will vary according to the situation. Therefore, in order to provide personalized treatment, the complete medical history of individual patients must be accessed. However, medical data is very sensitive and requires a secure sharing platform.
 
        The existing bookkeeping medical record system lacks privacy and interoperability. Blockchain can provide an infrastructure for integrating medical records and data integrity functions among different medical institutions through different kinds of ledger technologies. The blockchain can establish a strong and secure transparent framework to store digital medical records, thereby bringing high-quality services to patients and reducing treatment costs. Bshen et al. Proposed a license chain based framework called medchain, which is based on hyperledger fabric and can provide patients with full control over their medical records. Patients can use this distributed storage platform to share their health information to doctors or health centers.
 
        Deloitte also published a paper on bringing healthcare opportunities through blockchain based solutions (2016). This paper introduces how to reduce the interoperability in the healthcare system by using smart contracts and eliminating intermediaries, so as to reduce additional costs and make the system more robust.
