Core advantages of blockchain
broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
as we all know, blockchain technology is an independent underlying architecture from bitcoin system. From the perspective of architecture model, it is a set of distributed ledger, which is naturally used for bookkeeping
in the blockchain technology, if you want to generate accounting records, you need to have the transaction and flow of funds. Therefore, in the initial blockchain technology, the cryptocurrency corresponding to the main network is used as circulation goods, and the circulation transaction records of cryptocurrency between the accounts of the main network of the blockchain will be recorded on the main network
different from other transaction record databases, transaction records on the main network of blockchain technology will be recorded on all block nodes (i.e. all data blocks) in the main network, which is the so-called decentralization principle. That is to say, in blockchain technology, there is no central database to store all records, Every block on the chain has the transaction data of the whole chain, that is to say, every data block is the center
another feature of blockchain technology is that it can't be tampered with, because every transaction on the blockchain will be recorded in all blocks on the chain, so no single data block can change the record. Even if you change it, all other data blocks will also record real data, and each group of data can be traced back to the first time
because of these characteristics of blockchain technology, after the advent of bitcoin, blockchain has also attracted a lot of attention, and many people also began to want to use blockchain technology to make a centerless, traceable and unchangeable data, so as to ensure the credibility of the data
however, blockchain technology also faces many problems, such as single application scenario, non modifiable original error data, non recoverable currency stolen by hackers, etc.
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
take trading activities as an example. In the past, the two sides who did not trust each other usually chose an intermediary to guarantee a transaction. In the mobile Internet era, we chose Taobao shopping because Alipay provided us with an intermediate guarantee. We chose to drop dripping because it provided us with information matching.
however, these intermediaries are centralized and have their own interests. Sometimes they are not so reliable and trustworthy. Theoretically, Alipay's centralization of accounting has been artificially falsified. Part of the reason for Didi's troubles is that they only think from their own standpoint
what blockchain does is the machine of trust, which replaces the role of trust intermediary with code, ensures the fairness and justice of the whole system through consensus mechanism and distributed accounting, and provides a trust without trust
for example, in the future, people can abandon the intermediate platform and realize point-to-point docking and free trading through blockchain. Shopping does not need to go through an intermediary, and taking a taxi does not need to go through Didi. In this way, we can really achieve "no middleman to earn the price difference" and rece the cost.
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain< Second, openness:
the foundation of blockchain technology is open source. In addition to the private information of all parties to the transaction is encrypted, the data of blockchain is open to all. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent< Third, independence:
based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention< Fourth, security:
as long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily controlled and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes
5. Anonymity:
unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transmission can be carried out anonymously
Digital China is the first major development strategy explicitly put forward in the report of the 19th National Congress of the Communist Party of China. The application of digital technology represented by cloud computing, big data and mobile Internet is no longer limited to the economic field, but widely penetrated into all aspects of public services, social development and people's life, which requires macro coordination, overall control and integrated development
with the deepening of a new round of scientific and technological revolution and instrial change, the tide of digital economy in the world is unstoppable. The development of digital economy has become a global consensus, known as the key to the fourth instrial revolution
adhering to the connotation of the University of nice's world inclusive humanistic spirit, always embracing change, standing up to the tide, conforming to the development trend of the digital economy era, and integrating the essence of Chinese and Western cultural thinking, the University of nice's doctor of blockchain and digital economy management (DDE) came into being
based on this, we can enable the managers of digital economy instry to have global vision and global integration thinking, integrate knowledge, operate digital economy intelligently, promote the sustainable development of the instry, and contribute to the community of human destiny. Therefore, DDE project will cooperate with colleagues in the field of digital economy

In recent years, financial fraud, accountant audit failure and other risk events occur from time to time in the capital market, which brings legal risk and reputation risk to commercial banks, and has attracted the attention of the leaders of the State Council
on December 18, the "bank letter blockchain service platform" was officially released, which was launched by China Banking Association and China Institute of certified public accountants to actively implement the document requirements of the notice on further standardizing the work of bank letter and reply letter, study and promote the digital construction of letter, and improve the standardization level of letter business
"we hope that the future bank letter blockchain service platform can play a role in preventing and resolving risks, promote the improvement of letter quality and efficiency, strive to build a demonstration digital platform with high security, strong public welfare, convenience and efficiency, and make e contributions to improving the construction of social credit system and strengthening financial services for the real economy." Liu Fushou, chief lawyer of CIRC, said at the press conference
Pan Guangwei, full-time vice president of China Banking Association, said that in the future, China Banking Association will work with relevant institutions to promote the transformation and upgrading of letter business towards the direction of intensive operation and management, electronic path, standardized business process and refined data governance, improve the quality of accounting information and audit, promote the construction of social credit system and help the high-quality development of banking instry
three core advantages
bank letter and reply are the process in which the certified public accountant, after obtaining the authorization of the audited unit, directly sends the confirmation letter to the banking financial institutions, inquires about the authenticity of the audited unit's bank deposit, bank loan, guarantee, financial management and other information, and the bank inquires, checks the relevant information and provides the reply
According to pan Guangwei, letter confirmation is one of the core proceres of independent audit, which is crucial to identify errors and frauds in financial statements. For the whole financial market, letter work is related to the quality and efficiency of audit work, the quality of accounting information and the authenticity of capital market data, which is very important to prevent financial risks 
"the bank letter blockchain service platform adheres to the construction concept of authority, fairness and public welfare, follows the principles of marketization, openness and graalness, and graally promotes the transformation and development of bank letter to the direction of intensification, electronization, standardization and refinement, with three core advantages." Pan Guangwei said
one is platform target location. The platform has changed the offline decentralized letter reply mode to online centralized processing, which can complete the whole process of bank letter application, authorization, sending and reply online, speed up the letter processing efficiency, effectively solve various disadvantages of traditional paper letter mode, rece the degree of manual intervention of accounting firms, banks, audited units and other related parties, and enhance risk control, Rece the risk of data error and fraud
Second, in terms of platform security. The platform only retains the information of the letter transmission process, not the letter data information, and pays attention to the information isolation and confidentiality, so as to ensure the data security of banks and offices. The platform has a financial level security protection environment, which can realize 7 * 24-hour system safe operation
The third is the platform technical support. The platform chooses "ICBC Xi chain" as the underlying blockchain technology. ICBC Xi chain not only has significant technical advantages, but also has completely independent intellectual property rights. It has passed the authoritative certification of trusted blockchain of MIIT, and has many mature application projects100 banks have applied for access
at the press conference, pan Guangwei also said that after confirming that the bank letter platform takes blockchain as the underlying technology, the working group has carried out on-site communication with a number of technology companies with blockchain technology and scene application one by one. After experts' evaluation, the blockchain technology is selected to be independent and controllable, safe and reliable, and the business connection and scene application are improved ICBC technology, which has more advantages in later operation and maintenance, is the project contractor
it is understood that as the underlying blockchain technology, "ICBC Xi chain" participated in the trusted blockchain evaluation of China Academy of information technology in 2019 and 2020, and passed five technical evaluations of function, baas, performance, security and password with 100% passing rate. It is the first blockchain proct in the financial instry to be certified by an official authoritative evaluation institution
"with the strong support of instrial and Commercial Bank of China and instrial and Commercial Bank of China technology, the system development work was officially completed on October 26, and joint debugging and testing work was being carried out with a number of banks and accounting firms. At present, 100 banks and dozens of accounting firms have clearly signed up to apply for access to the platform. We will actively connect with banks and accounting firms to be connected to the platform, and provide solutions and training according to the needs of all parties. " Pan Guangwei said
Zhang Wenwu, vice president of ICBC, said at the press conference that ICBC has always paid attention to the quality of bank letter work, and ICBC technology company has further innovated and improved on the basis of ICBC's original letter e-letter, spared no effort in platform construction, and realized the platform's proction and online on schele“ The signing of the cooperation agreement will be taken as an opportunity for the first batch of banks to actively cooperate with the construction of the platform, promote the interconnection between e-letter and the platform, and fully support the use of the platform through the practice of centralized letter and certificate at the bank end. "
At the press conference, Liu Fushou also said that it is necessary to promote the construction of the letter certification platform in a safe and orderly manner, adhere to the principle of safety, prudence and risk control, adhere to the principle of pilot first and steady progress, and adhere to dynamic adjustment and continuous improvement
