Blockchain Bank Technical Cooperation Mode

1.

As a traditional financial institution, banks are the most active Pathfinder in the field of blockchain. In recent years, many banks at home and abroad have applied blockchain technology to credit, clearing and other fields. The unique trust mechanism of blockchain is regarded by banks as a key technological breakthrough in innovating risk management and simplifying transaction process. However, as an emerging technology, blockchain ecology is still in the process of establishment, and its application is very limited. Many problems still need to be solved graally in the development

"at present, blockchain can't run high-frequency and concurrent transactions, and network speed and computing power can't support it. For example, in the field of payment, if it is online shopping, it can be realized; If it's high-frequency futures trading, it can't be done. " Huang Zhen said

JIANG Peng said that at the beginning of designing the blockchain system, China CITIC Bank carefully demonstrated the business links suitable for the use of blockchain

"from the global experience, it is not suitable to use blockchain to build a large and complex system. Instead of trying to solve all problems with blockchain, we should focus on solving the core problems. It's time-consuming to build a too complex system. The technology is developing so fast that before the old system is finished, it will face the iteration of new technology. " Jiang Peng said

the idea of "only solving core problems" ensures that after the blockchain goes online, the relevant business operations of branches of China CITIC Bank can be upgraded without process transformation

Fan Bin said frankly that it will take time for banks to fully apply the blockchain, and IBM's investment in the blockchain open source community will continue, on the one hand to cultivate the market, on the other hand to compete for the commanding height of the blockchain platform. With the rapid iteration of blockchain technology itself, there is still a lot of imagination for financial institutions to use this new technology

Blockchain technology has the advantages of being difficult to tamper with and easy to trace. It can play a role in identity information management, trust mechanism construction, and credit information chain of small and micro enterprises

here is an example of a bank in Nanping:

e to the outbreak of online business, the original offline signing method has been unable to meet the needs of the rapid change of the banking business, and the bank's digital construction is imminent, but the bank's risk control department has strict compliance requirements:

< UL >

online business data sensitive privacy, Is the transmission secure

does the electronic signature have legal effect

can electronic evidence be accepted by the court

< / UL >

these concerns have become obstacles for banks to introce e-contracts and carry out business digital transformation

after adopting the unique ENA initiative forensics patent technology of the "real hammer" trusted electronic evidence platform, a bank in Nanping, through the clean server of the notary office, online carries out real-time preservation, storage and certification of the electronic data of the target system, records the whole process of the electronic data from generation, transmission to storage, and finally the notary office issues the forensics preservation report with official seal, The effectiveness of the documents is notarial documents, which can be directly accepted by the court. Because the report is issued by the notary office, it has more credibility than the self certification of the third-party E-contract platform, which solves the concerns of the risk control department of the bank at one stroke. The whole process is online and automated, and the front-end customer operation has no perception

at the same time, combined with the back-end case system of "real hammer" and the outsourcing execution service, the bank realized the rapid dispute resolution of Internet business. It not only ensures the compliance and effectiveness of the electronic contract signing process, but also solves the problem that the bank cases are scattered all over the country and the cost of legal business trip is high; The litigation cycle is long and there is no efficient disposal channel

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.

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

5. 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.

6. Chongqing jinwowo analysis: blockchain also comes with the technology of transaction confirmation. To realize the automatic confirmation of movable property rights for all participants in the supply chain, and form a common non tamperable record on the block chain, so as to solve the pain points in the existing right registration and right realization.

7. A: 1. The most common methods of cost accounting in commercial enterprises are purchase price method and selling price method
2. Purchase price accounting, also known as "purchase price bookkeeping, inventory and sales", is an accounting method that controls the purchase, sales and inventory of goods by the person in charge of the physical object (or counter group) based on the total amount of purchase price. Its accounting features are: after the purchase of goods, register the sub ledger of goods in stock set by the person in charge of the goods, only recording the amount of purchase price, not the quantity; After commodity sales, credit the "commodity sales revenue" account according to the actual sales revenue, do not carry forward the cost of commodity sales at ordinary times, conct regular physical inventory, find out the actual quantity, and calculate and carry forward the cost of commodity sales with the final purchase price method. This method is suitable for selling bulk commodities with large unit value. The disadvantage is that it's troublesome
3. Supermarkets and department stores usually use the "selling price method" to calculate the cost of goods. Price accounting method is suitable for retail businesses with complicated commodities, but the premise is that the price is uniform (indivial price changes also need to go through relevant proceres), the cost of sales is carried forward according to the price in each period, the price difference rate between purchase and sale is calculated at the end of the month, and then the price difference between purchase and sale of the sold commodities is obtained, and then the cost is adjusted. This accounting method is not applicable in today's market economy.

8. In theory, blockchain can subvert banks, but in fact, there is still a long way to go
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
blockchain is just a technology, which can be applied to many instries, such as logistics, crowdfunding, law, stock and securities. Nasdaq, eurocrowdfunding, Wal Mart, Wanda, Tencent and so on.

9. It's said that there is cooperation. In the future, it may be on the blockchain platform for loans...
