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

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 technologythe content comes from Xinhuanet
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. 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.

5. 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.
6. From the published R & D results, there have been some significant progress in the core basic technology fields of blockchain, such as "consensus algorithm", "encryption algorithm", "smart contract situational test". The feature of complete "decentralization" of blockchain is not applicable in the financial field, and distributed and polycentric is expected to become a realistic choice. Blockchain, known as a disruptive technology, will become the key infrastructure of Internet Finance and even the whole financial instry. At present, capital and institutions at home and abroad are speeding up the layout of blockchain technology. Experts said that the rapid development of blockchain technology is becoming a hot spot for investment. This year, the financing amount of blockchain venture projects has exceeded 1.4 billion US dollars
in recent years, the investment field has been paying more attention to blockchain. Since the beginning of bitcoin, blockchain technology has been explored in many application fields. Nasdaq, New York Stock Exchange, Citibank and other overseas financial institutions are also trying to carry out business innovation of blockchain finance, and the development of blockchain technology is also a major focus in China., For reference only!
