Blockchain technology is a decentralized distributed database that secures data transmission and access through the principle of cryptography. The data stored on the blockchain cannot be tampered with, which means that the data will never be lost. Blockchain technology has many application scenarios, including finance, healthcare, logistics and other fields. And the most important application now is digital currency.
Currently, many countries around the world are actively developing their own digital currencies and enacting relevant laws and regulations. Fan Yifei, vice governor of the People's Bank of China, said, "In the process of developing China's legal digital currency, we have actively drawn on international experience, while fully considering China's national conditions and market demand." There are now many companies and individuals who are focusing on blockchain technology, including companies we know well such as Baidu, Tencent, Alibaba, Jingdong and 360, which are also actively working on blockchain technology research and development.
Blockchain technology is now widely used in the financial sector, including payment clearing, transaction and data storage between financial institutions, supply chain management, etc. In supply chain management, the use of blockchain technology can improve management efficiency and reduce costs. In addition, blockchain technology can also be used in the medical field. In the medical field, information sharing such as electronic medical records can be realized through blockchain technology. And with the advent of the era of big data, this information sharing model will continue to be optimized and improved, providing greater help for the development of the medical industry.
