2. A few days ago, I saw an article on the official account of Zhang Ji's block chain, which is just about this. For example, after a thing is proced, its unique identification will be written into the blockchain, and then all logistics links and logistics status will be written into the blockchain together. If you want to buy this proct, you can query the information of each link of the proct in proction, logistics, sales and so on through the blockchain in advance. Combined with the Internet of things, only the manufacturer of this proct has the authority to link the proction information, and you can avoid buying fake goods from the source. This method can also be applied to all kinds of right

3. Blockchain is a technical solution to collectively maintain a reliable database through centralization and distrust. This technical solution allows any number of nodes in the participating system to calculate and record all the information exchange data in the system in a period of time to a data block through cryptography algorithm, and generate the fingerprint of the data block for linking the next data block and checking. All participating nodes in the system jointly determine whether the record is true
blockchain can improve the way of data recording in audit. In the current network audit, although there is an early warning mechanism, it still needs auditors to judge and handle the abnormal records manually; Blockchain can automatically process the abnormal records through whether each node verifies and approves the block and the transaction information in it, whether the network node is attacked, and whether the account book of each node is complete, so as to make real-time audit possible. Auditors can directly access and query the effective information on the blockchain, judge whether the processing is reasonable and make corrections. In the blockchain, timestamps are used to record various transactions and operations, which can achieve historical traceability and tracking, and greatly improve the quality and efficiency of audit
blockchain can change the storage mode of audit data. In traditional audit, data are stored in an audit center server, which not only has the problems of high load and slow running speed, but also is vulnerable to attack; The blockchain audit system is a typical distributed storage, each node has the same backup, which can not only save the high cost and maintenance costs of the server, but also ensure the integrity of the data
semi public private chain can be used for audit. Blockchain can be divided into three forms: public chain, semi open private chain and full private chain. Considering the characteristics of audit instry, it is appropriate to adopt semi open private chain mode. For the audited units and enterprises, some trade secret information is not disclosed, but the pre selected nodes within the group decide the generation of the block. External suppliers can participate in the transaction but not the accounting process. Externally, it provides a third-party query node to query through the open API. In this way, it can not only ensure the internal privacy of the enterprise, but also enable the external auditors to implement real-time audit query.

4. Blockchain technology is to use computers to solve some propositions that can't be calculated by human brain. Generally, these propositions can't be judged by backstepping. They can only be tested one by one, so this is our legendary mining. So the stronger the computing power of the computer, the easier it is to try to get the right number, which means that we have succeeded in mining
this is totally different from the operations in accounting. Most of the operations in accounting are floating-point operations, which are totally different.

5. From my understanding, blockchain is a kind of "consensus" implementation technology. Through blockchain, all transactions between the Internet can be recorded, which can be witnessed by users of blockchain to achieve "consensus", and the information content on the chain "cannot be tampered with". This "non tamperability" increases the cost of malicious tampering through the existence of multiple copies in the system. In the case of bitcoin, all the highlights in the figure below represent a consistent set of books. Therefore, when all the records are publicized, the problem of "two tables are not measurable" in real life is solved. The reason why the two tables can't be measured is that there is no center and the values of the two tables are different. But the center is not necessary. When there are multiple tables, and the majority pointer points to a time, the minority is subordinate to the majority, the viewer will know. Therefore, a problem to be solved by blockchain is that "the minority is subordinate to the majority". The existence of the minority may be the error of data generation or malicious tampering content. That is to say, if you want to tamper successfully, you must change 51% of the copies in the system [that is, 51% attacks], from a few to a majority. It can be imagined that the cost of tampering is huge in terms of technical difficulty, time consumption and personnel use. At the same time, another key combination of blockchain is the combination with smart contract. Because the former has achieved the "original" of the contract content, the latter has become the "Observer" to execute the contract by machine, which has eliminated the breach of contract and interruption of execution. From the earliest payment to the high development of financial derivatives, financial activities are all behind the signing and execution of contracts. At the same time, the vast majority of financial innovation is to ensure the implementation of the contract and default payment. If the signing of the contract becomes flat and implemented, the whole process will be more concise and efficient, which is a premise that blockchain will be valued by the financial sector.

6. The distributed architecture and tamper proof features of blockchain technology help to solve the problems of bill authenticity and information opacity. When participants need to check whether the bill has been tampered or transferred, blockchain can provide indisputable proof of consistency
digital currency also makes use of this feature of blockchain. Puyin is a kind of tea standard digital currency developed based on blockchain technology.

7. View the usage of mod, and add it in mod option (main interface).

8. Blockchain is an effective way to enhance the authenticity and reliability of financial information.

9. The prevention of financial and accounting fraud can be carried out from two aspects of ecation and system:
first, constantly improve the ecation of accounting professional ethics

honesty and law-abiding is the basic requirement for every accountant and even every citizen. The professional quality of an accountant will directly affect the quality of his work, In order to improve the authenticity of accounting information, we must first improve the professional ethics of accountants. Therefore, we should establish the system of accounting professional ethics and constantly strengthen the ecation of accounting professional ethics, so that all accountants can abide by the law and discipline, and take a disdainful and disdainful attitude towards accounting fraud< Second, strengthen the implementation of centralized accounting
the implementation of centralized accounting and accounting can grasp and supervise each fund activity of each unit in an all-round and whole process, and can provide guarantee for the orderly and planned capital expenditure of each unit. The accounting center should select full-time accountants with high professional quality to be responsible for the daily fund revenue and expenditure, and check the fund revenue and expenditure regularly to prevent accounting information distortion caused by false accounting. At the same time, it should establish clear expenditure standards, standardize the expenditure channels, and seriously deal with the phenomenon of comparing with each other and abusing money and goods, In addition, we should also introce some computerized accounting systems to improve the efficiency of accounting staff and the quality of accounting information.

10. Separation of money and account. That is what we usually say, the accountant does not care about the money, the cashier does not care about the account. Money and account should be separated and balanced. The cashier is responsible for registering the cash and bank journal. After recording, he will transfer the documents to the accountant. The accountant will register the bookkeeping voucher according to the original voucher, usually half a month or a month. The accountant and the cashier need to check the cash and bank account, that is, the balance of the cashier's journal should be consistent with the balance of the accountant's financial account, and, The cash on hand of the cashier should be equal to the balance of the financial account. This is called the fact that the account is consistent with the fact

separation of account and reality, that is to say, people who manage physical objects can no longer manage accounts. This is similar to the separation of money and account. People who manage physical objects only need to keep a good record of their own physical accounts. They can't manage both physical objects and accounts, which is prone to fraud

to check the cash cashier and the physical goods warehouse regularly, the financial department needs to add a supervisor to check the cash and physical goods regularly. Verify whether the account is consistent with the actual situation, if not, find out the reason in time, and put forward the handling opinions.
