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. 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

3. 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
4. What can blockchain do? Blockchain, a great technology with the birth of
bitcoin, can greatly rece transaction costs and improve efficiency in the financial field, which is enough to make Wall Street excited. However, this is only the tip of the iceberg, and its potential application prospects are very wide, which will subvert all aspects of our lives in the future. Internet is an information network with 0 and 1 flowing in it. Blockchain is a value network, which plays a role in value transmission, which is different from Internet in data transmission. When it comes to value transfer, there is a very simple scenario, such as payment. I have 100 yuan in hand. I want to transfer to the group by wechat red envelope or wechat transfer. In this transaction process, a third party is required to participate, while the transmission mode of blockchain is point-to-point transmission, without any intermediate node, This is a big difference between blockchain and our existing architecture. When it comes to point-to-point payment, many people think of bitcoin, because most people know about blockchain from bitcoin. What's the difference between blockchain and bitcoin? Blockchain is the technology behind bitcoin; Blockchain is a basic technical architecture. Through a specific data structure and consensus algorithm, an autonomous system with multi-party participation is designed and implemented. A specific data structure is actually the name of the blockchain itself, that is, its data is put in a block of data blocks, and then the data blocks are connected and implemented by a chain“ "Consensus algorithm" is a very important concept in blockchain. Without synchronic algorithm, there will be no blockchain. Introction to Bubi blockchain since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts. It has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically proven distributed consensus technology, fast large-scale ledger access technology Multi Chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely. So far, let's analyze the difference between blockchain and bitcoin? 1. Essential difference. For the world, bitcoin is a
digital currency based on cryptography, while blockchain, as we have just said, is a protocol of value transmission. There is an essential difference between the two, because one is digital currency and the other is a protocol of value transmission. 2. Algorithm. The consensus algorithm of bitcoin is based on a work algorithm called workload proof, pow. There are many different consensus algorithms in blockchain, including bitcoin POW algorithm, POS algorithm and DPS algorithm. 3. Transaction speed. Bitcoin has a maximum of seven transactions per second. Please note that we are talking about the maximum rather than the average, because this is a very strict definition. For blockchain, the number of transactions per second can reach tens of thousands or so, so this is also a major difference between blockchain and bitcoin. Because many people will confuse that the transaction speed of blockchain is seven transactions per second, which is wrong. This is a limitation of bitcoin. Blockchain can achieve very high transaction speed according to its different consensus algorithms and linking methods. 4. Link form. Bitcoin is a blockchain based on the Internet, that is to say, we call it public chain. Blockchain can be in the form of public chain, private chain or alliance chain. 5. Limitations. It is suggested that you do not touch some digital currencies related to blockchain. What is the reason? Bitcoin, as a digital currency, although it has very different characteristics, it does not comply with financial regulation. In other words, the 21 million bitcoins were issued without national authorization and national credit as a multiple. Blockchain also has some limitations. Although it is only a protocol and a technology, it is still a new technology in its infancy. To sum up, blockchain is a relatively low-level protocol and a technical infrastructure, on which there are various consensus algorithms. If the blockchain is 1, the consensus algorithm may be 10 to 20, but there may be 1000 or 2000 applications on it. In other words, bitcoin is only one implementation of many blockchain applications. Therefore, bitcoin and blockchain are not equal. Bitcoin is only a very primary implementation of blockchain. What can blockchain do? What about blockchain? In the bill market, the digital bill based on blockchain technology can become a safer, more intelligent and more convenient bill form. The point-to-point transaction with the help of blockchain can break the existing function of bill intermediary and realize the disintermediation of bill value transmission; The construction and data storage of the digital bill system do not need the central server, which saves the development cost of the central application and access system, reces the maintenance and optimization cost of the system under the traditional mode, and reces the risk of the system centralization; Based on the non tamperability of information in the blockchain, once the bill transaction is completed, there will be no default phenomenon, so as to avoid the behavior of "selling more than one vote" and asynchronous payment and endorsement, and effectively prevent the bill market risk. The securities exchange market is also a promising field of blockchain technology. At present, the traditional securities trading mode has the disadvantages of long trading process, low trading efficiency and high comprehensive cost, and there are strong intermediaries and regulatory agencies, so the rights of financial consumers are often not guaranteed. With the application of blockchain technology, buyers and sellers can directly pair through smart contracts, and the efficiency of transaction execution can be greatly improved. Through the distributed digital registration system, settlement and delivery can be automatically realized. Because the data entered into the block is irreversible and can be copied to each data block in a short time, the information entered into the block chain actually has the effect of publicity, so the occurrence of transactions and the confirmation of ownership will not be controversial. What can blockchain do? What about blockchain? Although at present, there is no mature underlying blockchain technology platform solution, technical problems such as capacity scalability, privacy protection, non net settlement and non recourse need to be solved, and large-scale application of blockchain technology also needs to reset it architecture and reengineer business process, these are only technical problems. The real test of blockchain technology rooted and growing in the financial field is the regulatory agencies and financial institutions. Will the inherent "de supervision" and "de centralization" characteristics of blockchain make the market players have no power to drive technological innovation. However, because the blockchain is a technology based on mathematical algorithm, the establishment of trust relationship between all parties does not need the help of intermediaries or authority centers, and the cost of establishing trust relationship is almost zero (on the premise of the establishment of blockchain financial infrastructure and ancillary infrastructure), and the blockchain code is open-source, no geographical restrictions, and the network pattern is distributed and interconnected, It lays a technical foundation for the establishment and development of Inclusive Finance and shared finance in the future, and creates material conditions for the integration and unification of global finance. From this point of view alone, blockchain technology is bound to establish a core position in the future financial development, and rely on and complement each other with finance, and win-win in the future.
5. 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.
6. 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.
7. 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.
8. What should we do if we can't exchange currency for foreign exchange? You can go to the Bank of China to exchange foreign exchange
