Disadvantages of blockchain Distributed Accounting

1. That's a good question. Let me give you an example. For example, when I deposit 100 yuan in the bank, the data of this deposit is only recorded in the bank's database, which can't be obtained by others, namely "central bookkeeping". The blockchain is a distributed accounting, a new information recording technology, and it is "encrypted" and "distributed". The data does not exist in a center, but is stored once on the computer of the whole network. For example, if I transfer 100 yuan to you, I will shout to all the computers in the whole network. Let's record the accounts together, that is, "Distributed Accounting".

2. Bookkeeping means mechanisms such as distributed bookkeeping, collective agreement and intelligent consensus. Blockchain technology presents information processing characteristics such as centralization, open sharing, authenticity and reliability, which has aroused increasing attention and application in the financial field, especially in the field of Internet finance. There are many blockchain system development companies. Blockchain technology development enterprises like Renren chain are reliable. You can learn more about them

3. For the benefits, jinwowo feels that the biggest benefit is to obtain great security. First of all, there is a central ledger, so it cannot be destroyed. As like as two peas, each node is only part of the system, and each node has the same rights. Destroying some nodes has no effect on the system at all. Secondly, you can't cheat, because unless you can control most people's computers in the system to make changes, the system will refer to the opinions of most people to decide what is the real result. As a result, it will find that it is totally meaningless to modify your own account book (because others don't admit it). Secondly, since there is no centralized intermediary, making everything run automatically through preset proceres can not only greatly rece costs, but also improve efficiency. Since everyone has the same account book, it can ensure that the process of account book recording is open and transparent.

4. Blockchain technology will not affect efficiency and waste computing power. The key is to see how to innovate in a mode and how to use blockchain technology efficiently to achieve the effect of the mode
blockchain is essentially an encryption algorithm, which is based on the principle of hash 256 bit algorithm to achieve information security; The application of modern information will become more and more global and universal. Besides the basic requirements of anti tampering, anti repudiation and trustworthiness, the protection of privacy needs to be strengthened. The blockchain technology is proced because of the development of modern cryptography. The cryptography used today is the result of cryptography 20 years ago, Therefore, in order to apply the blockchain technology to more participation scenarios, especially in the Internet economy, more verification is needed to verify whether the existing encryption technology can meet the demand, and more in-depth integration of cryptographic frontier technology and continuous innovation are needed
as long as we use blockchain to make innovations in accounting methods based on our own mode, it will not affect efficiency and waste computing power, but will shorten the time and improve efficiency.

5. 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.

6.

Distributed accounting technology is a database distributed on multiple nodes or computing devices. Each node can and save a ledger, and each node can update independently. Its feature is that the ledger is not maintained by any central organization, and the update of the ledger is built and recorded by each node independently

The

node can vote on these updates to ensure that they are in line with the majority opinion. This kind of voting is also called consensus, and consensus is automatically reached through the algorithm. Once a consensus is reached, the distributed ledger will update itself, and the latest agreed version of the ledger will be saved on each node

distributed accounting technology solves the problem of trust cost, which is less dependent on banks, government and Justice Department, and the data is all on nodes. At the same time, it also solves the problems of consumer rights, financial integrity and transaction speed

extended data:

distributed ledger is a kind of database shared, copied and synchronized among network members. Distributed ledgers record transactions between network participants, such as the exchange of assets or data. This shared ledger eliminates the time and expense of mediating different ledgers

distributed ledger (also known as shared ledger, or distributed classification technology) is a replication consensus, sharing and synchronizing digital data geographically distributed in multiple websites, countries, or institutions. There is no central administrator or centralized data storage.

a point-to-point network is required, and consensus algorithms are used to ensure replication at nodes. A form of distributed classification design, blockchain system, can be public or private

but not all distributed accounts must use chain blocks to provide security and effectively realize distributed consensus: blockchain is just a type of data structure, which is considered as a distributed ledger. In 2016, many banks tested the balance of payments account

the participants in the network restrict and negotiate the updating of the records in the account book according to the consensus principle. There is no intermediate third-party arbitration institutions (such as financial institutions or clearing houses) involved. Each record in the distributed Ledger has a time stamp and a unique password signature, which makes the ledger an auditable history of all transactions in the network

7. For example. The enterprise will record its income and expenditure in its own account book. There are two problems in using traditional bookkeeping methods. First, the enterprise will tamper with the account book, so there will be a series of external constraints, such as audit and taxation, to ensure that the enterprise does not make false accounts. The second problem is that the backup number of traditional account books is limited. If all these account books are lost, it will be a great blow to the enterprise. In the world of blockchain, every transaction and every data will be backed up by tens of thousands. In this way, the problem of account loss will not occur. Moreover, when someone wants to tamper with the account book, they need to tamper with thousands of account books, which is very difficult.
