With the continuous improvement of China's macro-policy in the field of blockchain and the continuous increase of industrial investment, the research and application of blockchain technology is changing rapidly and vigorously. The integrated application of blockchain technology is in new technological innovation and industrial transformation. Plays an important role. We must regard blockchain as an important breakthrough in independent innovation of core technologies, clarify the main attack direction, increase investment, focus on overcoming a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation.

As an important breakthrough in independent innovation, what kind of technology is blockchain? In theory, the blockchain is a set of information governance frameworks based on the combination of theories of computing science, cryptography, the Internet and other multi-disciplinary fields under an incentive and constraint mechanism. In layman's terms, blockchain is not a specific product. It can be understood as a technical solution for public accounting, that is, by establishing a set of public ledger on the Internet, all users on the network work together on the ledger. Bookkeeping and auditing to ensure the authenticity and immutability of information. Because this "public ledger" uses a series of data blocks associated with cryptographic methods, which contains all transaction information from the past period of time, which is used to verify the validity of the recorded information and generate the next block, it is therefore Called "blockchain." It is essentially a decentralized distributed database, an innovative application model of multiple technologies such as distributed data storage, consensus mechanisms, and encryption algorithms in the Internet era.
The core functions of the blockchain, one is machine trust, the other is value transfer, and the third is smart contracts. In a word, it is to build a trust mechanism. It has the three characteristics of decentralization, complete traceability, and decrediting, which further guarantees the "honesty" and "transparency" of the blockchain and lays the foundation for creating an unconditional trust system. Nowadays, the application of blockchain technology has been extended to many fields such as digital finance, the Internet of Things, intelligent manufacturing, supply chain management, and digital asset trading, which has promoted the high-quality development of China's economy. General Secretary Xi Jinping emphasized the need to explore the application of "blockchain +" in the field of people's livelihood. In fact, various applications of blockchain technology have entered the daily lives of ordinary people.
"Blockchain + public services" makes it easier for the masses to do things. In some places, blockchain technology has been introduced into government services, and a blockchain government service platform has been established. The time for registering a company has been shortened from a dozen days to three days after the launch. Service efficiency and service satisfaction have both improved.
"Blockchain + supply chain" makes food and medicine more reliable. Traditional supply chains have disadvantages such as opaque information, easy data tampering, and poor security. Consumers often worry about eating fake medicines and inferior food. After using the blockchain technology and the Internet of Things technology to implement the full traceability of the commodity information, the raw material purchasing process, production process, and distribution process of the commodity are fully integrated. The harvest time, processing time, geographical location of each bag of rice, and each box The basic ingredients, production time and place of the medicine are all recorded on the chain and fully displayed to consumers through multiple network channels, which significantly enhances their trust experience.
"Blockchain + Medical" , it is more convenient to seek medical treatment. The medical data sharing and exchange system developed using blockchain technology uploads the encrypted medical data so that it can circulate quickly and securely between patients and medical institutions, providing data support for accurate diagnosis of the disease. At present, the blockchain platform suitable for the treatment of chronic diseases has been put on the market. Regulators, medical institutions, third-party service providers and patients themselves are included in the blockchain to implement data sharing and management, and implement an integrated chronic disease intervention mechanism to ensure that Disease is effectively controlled.
"Blockchain + social assistance" , recipients are more accurate. Social assistance work, which is an important part of the social security system, has many disadvantages due to various complex factors, especially the "missing insurance", "wrong insurance", "fraud insurance", and "relationship insurance" and "relationship insurance" in urban and rural minimum guarantees This phenomenon is often criticized by the masses and public opinion. After the introduction of blockchain technology to establish a personal income comparison platform, it has gathered a large amount of data from labor employment, market supervision, tax registration, and vehicles, housing, medical and other departments, which can accurately provide helpers with economic income, family population, physical health, etc. The situation is convenient for people, households, and time to provide assistance.
The application scenario of "blockchain + people's livelihood" is far more than the above. In theory, all people's livelihood services that require information as the basis, collaboration as a means, and the purpose of value transfer, such as certificate processing, insurance claims, and bank credit reporting Evidence from judicial trials, as well as the pursuit of public welfare funds, the use of lottery public welfare funds, etc., can be used to improve the work plan and improve the level of governance through blockchain technology.
