block head: record the characteristic value of the current block
block body: actual data
2. Blockchain is an innovative application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies in the Internet era. In recent years, the development and application of blockchain is of great significance to technological innovation and instrial revolution. This experience introces the relevant knowledge of blockchain technology
3. Blockchain is a distributed ledger, which can contain financial and / or non-financial transactions. It can be replicated (distributed) on multiple systems in almost real time through peer-to-peer network. Each participant "owns" the same ledger and gets updated when adding any transaction. Each participant helps to determine the inherent "invariance" of all existing records, Using cryptography and digital signature to prove identity, authenticity and enforce read / write access, there is a mechanism that makes it difficult to change history, and it is easy to detect someone trying to change it.
Blockchain technology is widely used. Under the integration of new technologies, the main application scenarios of blockchain include finance and insurance, intelligent manufacturing, intelligent environmental protection, energy and power, health care, ecation, culture and innovation, smart city, social welfare, agriculture and many other fields

3. Blockchain + government
in statistics, voting, budget management and other aspects, blockchain can rece costs, improve efficiency, and increase transparency, so as to prevent the risk of failure of centralized system
4. Blockchain + insurance
fraud identification and risk prevention: by placing insurance claims under an unchangeable general ledger, blockchain helps to eliminate the common sources of fraud in the insurance instry
property insurance and accidental injury insurance: policies and shared ledgers recorded in the form of smart contracts can improve the efficiency of property insurance and accidental injury insurance
Health Insurance: blockchain technology enables medical records to be encrypted and shared among health service providers, thus improving the interoperability of the health insurance ecosystem
Reinsurance: the information security of reinsurance contracts on the blockchain platform can be ensured through the form of smart contracts, which can rece the amount of information and simplify the payment process between insurers and reinsurers
Blockchain instry development trend analysis technology has broad application prospects
with the characteristics of point-to-point payment, openness and transparency, the most direct application field of blockchain technology application is payment field. However, there are many pain points in domestic ticketing instry, such as too many agent levels, rampant scalpers, selling more than one ticket, fake tickets, lack of credit, etc, It can be solved by blockchain technology. The traditional ticketing mode needs the support of centralized facilities such as the third-party ticketing platform, and the information is extremely asymmetric. The new ticketing mode based on blockchain technology can realize point-to-point transaction, and the whole process is transparent and traceable

data source: the financial field of blockchain + application sorted out by prospective instry research institute is reshaping the financial instry pattern
the open and tamperable attribute of blockchain technology provides the possibility for decentralized trust mechanism,
has the potential to change the financial infrastructure. All kinds of financial assets, such as equity, bonds, bills, warehouse receipts, fund shares, etc., can be integrated into the blockchain ledger to become digital assets on the blockchain. They can be stored, transferred and traded on the blockchain, which makes them have a very broad application prospect in the financial field
by recing the cost of cross-border payment, securities trading and compliance, blockchain technology can save banks $15 billion to $20 billion a year
through the application of intelligent contract, blockchain + insurance can realize automatic claim settlement of insurance policy. Insurance institutions have high management and operation costs, and the data on the blockchain is true and reliable, which can effectively simplify the processing process of policy claims. In addition, the blockchain technology can realize the digital management of personal data, simplify information authentication, and help to trace the history of data
entertainment of blockchain + application: the development ecology of blockchain has taken shape, and the media instry may become the main beneficiary
blockchain technology can be widely used in news, games, picture right and other entertainment fields
blockchain technology will bring great changes to the underlying structure of the game and have a great impact on the current game instry. Gamers now have gatekeepers (centralized organizations) to decide prices, tax, censor users, control content, and profit from data. Through the decentralized platform, consumers can socialize and trade without mediation, providing more control and flexibility for game players in the game experience
blockchain + applied supply chain: it can improve the transparency of the supply chain, establish a new supply chain system
blockchain technology can improve the transparency, traceability and security of the supply chain, and promote a kind of trust and integrity. 1) At present, the supply chain has many disadvantages, such as long chain, many intermediate links, many interest joints, opaque and so on; 2)
the distributed bookkeeping technology of blockchain can register the transfer of goods on the ledger as a transaction, and determine the participants related to the proction chain management, as well as the proct price, date and location
it's not a file, it's not that simple. Simplicity is not safe for the owner.
