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
On September 18, 2018, Hangzhou Internet court was officially put on the chain and became the first court in the world to use blockchain for trial
it is understood that prosecutors can submit electronic evidence such as contract, rights protection process and service process details online through online appeal portal, and notarization office, forensic identification center, CA / RA organization, court and other chain nodes can witness and endorse together to provide one-stop service for prosecutors. Hangzhou Internet court of Zhejiang Province made a public judgment on a case of infringement on the right of network dissemination of works' information, and confirmed the legal effect of electronic data with blockchain technology for the first time
2. In the field of logistics
in early 2018, rookie and tmall global jointly announced that blockchain technology has been used to track, upload and verify the logistics full link information of cross-border imported goods
after all nodes of the logistics chain are connected to the blockchain, the goods can be traced from manufacturers to consumers, forming a complete chain; The more links the commodity is missing, the more likely it is to be a fake proct
3. Electronic invoice
on August 10, 2018, Shenzhen International Trade revolving restaurant issued the country's first blockchain electronic invoice. It is understood that this blockchain electronic invoice was led by Shenzhen Taxation Bureau and provided by Tencent with underlying technology and ability
different from traditional e-invoice and simple e-invoice on the chain, this blockchain e-invoice combines "capital flow and invoice flow", combines invoice issuing with online payment, and gets through the whole process of invoice application, invoice issuing, reimbursement and tax declaration
there are still many practical applications of blockchain. You can learn more about relevant information
in September 2016, Weizhong bank and Shanghai Huarui bank put into trial operation the inter-bank joint loan clearing platform based on alliance blockchain technology to optimize the settlement and clearing of "micro loan" joint loans of the two banks. With the introction of the blockchain system, all the information is recorded on the blockchain network, which can not be tampered with. The transaction process is cleared at the same time, realizing real-time clearing, saving a lot of manpower and material resources
2. China UnionPay uses blockchain technology to realize inter-bank points exchange
in September 2016, China UnionPay and IBM tried out a shared points system based on blockchain technology. Using this blockchain system allows users to exchange bonus points across banks and platforms. In other words, the bonus points of one bank can be exchanged for bonus points of other banks, or even multiple airline mileage and supermarket awards. It greatly improves the use efficiency of bank points
3. Toyota uses blockchain technology to track auto parts
in October 2016, Toyota joined R3 alliance to store the proction, processing and use of each part in the blockchain through blockchain technology, so that when there is a problem with auto parts, the source of the parts can be easily and quickly found
4. Central bank's blockchain digital bill trading platform
in January 2017, the central bank's blockchain based digital bill trading platform was successfully tested. The introction of digital currency for settlement can realize the synchronous transfer of capital flow and information flow of digital bill transaction, so as to realize DVP bill settlement. At the same time, the blockchain digital identity solution solves the problem of repeated KYC authentication between different financial institutions. It not only solves the problem that the transaction amount of digital bills is confidential to the unrelated parties, but also ensures that the regulatory parties such as the exchange have the mechanism of seeing through when necessary
5. Ant financial services blockchain application
in August 2017, ant financial services blockchain technology tested water insurance and helped Xinmei mutual insurance company to launch the first love rescue account in the domestic insurance instry. Blockchain technology makes every capital flow open and transparent, the data of every capital flow can not be tampered with, and the whereabouts and uses of every capital can be traced. In November of the same year, ant chain was used in food safety traceability and traceability of genuine procts. At present, the milk powder proced in Australia and New Zealand and Moutai in China, users can only know if they are genuine procts by scanning Alipay.
there are many other successful cases at home and abroad, all of which indicate that the application of blockchain technology is graally promoted, and is favored by various instries. Accompanied by the emergence of many blockchain technology companies, they want to take a share in this field. However, after the people's Bank of China and other seven ministries and commissions issued the "notice on preventing the financing risk of token issuance"), with the increasing difficulty of registration, there are more empty shell companies in the intermediary instry chain, and few companies have practical applications
in addition, the security technology of blockchain has always been concerned and controversial. Nowadays, blockchain mainly faces five security problems: the security of underlying code, cryptographic algorithm, consensus mechanism, smart contract and digital wallet.
At present, companies in medical, government, transportation, technology, manufacturing, entertainment, games and other fields are already using blockchain technology. As shown in the figure below, blockchain has proved to be very useful in various fields. Currently, the listed companies using blockchain include Facebook, Alibaba group, Microsoft, Siemens, Ford Motor Company, etc
the second is that only mature technology is not enough. In order to realize a large number of DAPP and commercial applications on the blockchain, we must be prepared on one hand: that is, the digital currency that can be used as payment tool, exchange medium, value measure and value storage. Xiao Feng said that everyone thinks that bitcoin is a payment system, but the real bitcoin can not meet our demand for payment because its currency value fluctuates too much
for example, he said that a mall sold a bottle of water and accepted bitcoin payment. When he got up the next morning, he found that 20% of the value was gone. So it can't be accepted. After the Japanese parliament made it clear that bitcoin could be used as a payment tool, some Japanese businesses announced that they would accept bitcoin payment. But later found that it caused a lot of trouble for the stability of the company's balance sheet. Your balance sheet is unstable, up or down. This not only affects the value of the things sold, but also affects the credit evaluation of enterprises and the services provided by banks to companies
the third condition is the construction of laws and regulations and supervision system. The digital economy on the blockchain must obtain legal protection and comply with the law. Xiao Feng stressed that there can be no decentralization in this regard
the differences between blockchain and Internet are discussed. He believes that the core difference between the two is that the Internet is a centralized trust mechanism, while the blockchain is a decentralized trust mechanism, and there is no need to trust a third party
the second core difference between the Internet and blockchain is the incentive mechanism, not the digital currency or the ability to issue currency. Economics has been discussing incentive incompatibility. Under the company system and on the Internet, the incompatibility of incentive mechanism has not been solved. However, in the decentralized blockchain, the blockchain achieves complete incentive compatibility. Without shareholders, board of directors and employees, the conflicts of interest between these roles will not happen again.
