Blockchain and Banking

1. The word subversion is a description of media's unscrupulous and eye-catching behavior. The correct posture is that blockchain will help the banking instry improve its security and efficiency
traditional banks are centralized account books, and regulators have a general ledger in their hands. We need to use a sum of money. The general ledger records the information about the change of money. If the general ledger server is hacked, or someone who has the right to modify the account book has done something wrong, then our deposit data will be wrong. That's why some customers' deposits have disappeared
the blockchain is a distributed ledger. On the blockchain, the synchronized ledger is stored on the global nodes. If it is to be modified, the technical rules of the blockchain force that more than 51% of the global server nodes must be modified. The theory is feasible, but the fact is not
banks close down at 16:30 p.m. every day. One of the things they have to do is to centralize and exchange transaction data among banks. With blockchain, this link is saved. Direct point-to-point real-time exchange
when you go to the bank to open an account and do business, the information is repeatedly provided again and again. If the user uploads the instrial and commercial data and personal data to the blockchain, a two-dimensional code can download the user's information, which is more secure and accurate, saves a lot of trouble, and greatly improves the security and efficiency

2. 1. Weizhong bank uses blockchain technology for loan clearing
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.

3. Blockchain is a technology that can completely change the underlying design of the financial system, because it can realize the undifferentiated record between the ownership of all assets in the market and the transaction records of all market participants, so it can completely eliminate the intermediate links of clearing and trusteeship, which are used to confirm the ownership before, ring and after the transaction; In addition, as an electronic information record, blockchain can be combined with computer algorithm to realize the automation of transactions, that is, intelligent contract. There are many derivative applications of blockchain combined with other financial technologies, each of which can replace a kind of market intermediary. Blockchain is to financial services what TCP / IP is to the Internet: once the underlying standards are recognized and popularized, specific applications like bitcoin and R3 will appear in every corner of financial services. Bitcoin uses blockchain technology to query and record. For example, if I register an account in haobtc and transfer the money, I need to query the status in the block browser in the account or the block browser in BTC. In this way, the blockchain technology helps me solve the problem of daily transfer currency query.

4. Now is the information age, no good technology is difficult to stand in the society,
now the rapid growth of computer technology, every company needs computer talents, you can go to learn computer professional,
there is still a lot of development space in this field, as long as you study hard, the future prospects are unlimited.

5. This can be directly checked on the Internet. There should be a detailed ranking list on the Internet. As hkongex is so good, it should also be in the ranking list.

6.

Yes, the current deception is not surprising. In short, you should be more careful

with the rapid development of mobile communication, online dating has become a widespread form of communication, but there are some sweet traps set by outlaws. How to avoid being cheated in the complicated virtual space, so as to avoid unnecessary property losses

for example, he said that in his uncle's home in Taiwan, he sent a table of food, enlarged the picture, and you can see the logo of the drink, which is obviously a mainland brand, which needs to be seen carefully

7. There are two roles and four moles in the cross-border payment solution based on euz. The two main roles are the gateway and customer participating in the euz payment. They are as follows:
the first role is gateway, which can be bank, market maker, liquidity provider, etc. The main function of the gateway is to let the legal assets in reality enter the blockchain payment and settlement network
the second role is customers, which can be all kinds of international trade customers. Customers are the parties involved in the blockchain payment transaction, and jointly participate in the confirmation of transaction information. In the process of transaction, once either party does not confirm the transaction, the transaction cannot be formally effective. Through this common verification, the risk of information opacity is greatly avoided, and the risk of cross-border payment in international trade is reced
the four functional moles in blockchain payment and settlement are the core business logic moles in cross-border payment
the first function mole is network connector. It is a tool to help all kinds of institutions access blockchain payment network as gateway. Network connector is a "plug and play" function mole, which can be integrated with the existing international payment and settlement system, so that banks can process cross-border payment business through blockchain. The mole is connected with the remitting bank and the receiving bank to exchange personal information, expenses, delivery details, payment details, etc. After the system confirms the transaction information of both parties, the mole connects the blockchain payment ledger for settlement processing, and notifies all parties to confirm the transaction
the second function mole is blockchain payment ledger. Banks, market makers, etc. access blockchain payment books as nodes
the third function mole is the market maker client. The market maker submits digital assets to the blockchain payment account book, and the settlement platform can realize the function of market maker through internal exchange settlement or integration into the blockchain payment network through this mole
the fourth function mole is transaction client. Customers can directly operate blockchain payment settlement through the client.

8. With the advent of "digital era" and the development of financial technology, the environment that banks are facing is more complex, and the pressure of "financial disintermediation" is further increasing. The operation of commercial banks is faced with such transformation and development issues as data capitalization, service scenario and flat architecture. Blockchain can effectively promote the transformation of traditional business forms of banks, rece losses, enhance trust and efficiency, and help banks to establish a more flat structure and more agile mechanism. In fact, not only banks, but also other instries can apply blockchain. The blockchain service platform project launched by Changsha high tech Zone is a blockchain + public service mode, and enterprises are being recruited to join the chain. In the future, relevant enterprise affairs and government affairs can cooperate on the chain.

9. Blockchain... Is the way to integrate resources. It doesn't make much sense. Don't listen to some people's nonsense.
