『一』Big Data and Blockchain

This story still has to start with Bitcoin

Bitcoin, an electronic cash system, is also Disintermediation (electronic cash between individuals does not require the intervention of a trusted third-party intermediary) and decentralization (maintained by an institution) (both parties to the transaction can complete transactions without establishing a trust relationship) < br />
Hash function: Convert an arbitrarily long string into a fixed-length output (the calculation process cannot be too complicated). As long as the input string changes slightly, the output of the hash function will be completely different.

Blockchain: Divide large things into many blocks for storage. As long as one thing is tampered with, the data below will be different and it will be discovered

Uses blockchain (data structure hash function) to ensure that the ledger cannot be tampered with, uses digital signature technology to ensure that only you can use your own account, and uses p2p network and POW consensus mechanism to ensure decentralized operation.

Blockchain is a method that uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access security. A new distributed infrastructure and computer paradigm.

Three elements:

The essence of blockchain is a distributed ledger, a kind of database. The blockchain uses a hash algorithm to ensure that information cannot be tampered with, uses public keys and private keys to identify identities, and collectively maintains a reliable database in a decentralized and disintermediated manner.

The differences between big data and blockchain are mainly reflected in the following aspects.

(1) Data volume. Blockchain technology is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithms. The amount of data processed by the blockchain is small and has a meticulous processing method. Big data manages massive amounts of data, which requires breadth and quantity, and the processing methods will be rougher.

(2) Structured and unstructured. Blockchain is a block with a rigorously defined structure. The chain composed of pointers is a typical structured data, while big data needs to process more unstructured data.

(3) Independence and integration. In order to ensure security, the blockchain system's information is relatively independent, while the focus of big data is the integrated analysis of information.

(4) Direct and indirect. Blockchain is a distributed ledger, which is essentially a database, while big data refers to in-depth analysis and mining of data, which is a kind of indirect data.

(5)CAP theory. C (Consistency) is consistency, which refers to anyA read operation can always read the result of a previously completed write operation, that is, in a distributed environment, data at multiple points is consistent. A (Availability) refers to availability, which refers to obtaining data quickly and returning operation results within a certain time. P (Tolerance of Network Partition) is partition tolerance, which means that when a network partition occurs (that is, some nodes in the system cannot communicate with other nodes), the separated system can also operate normally. CAP theory tells us that a distributed system cannot meet the three requirements of consistency, availability, and partition tolerance at the same time. It can only meet two of them at the same time. As the saying goes, "You can't have your cake and eat it too." Big data usually chooses to implement AP, and blockchain chooses to implement CP.

(6) Basic network. The underlying infrastructure of big data is usually a computer cluster, while the infrastructure of the blockchain is usually a P2P network.

(7) Source of value. For big data, data is information, and value needs to be extracted from the data. For blockchain, data is an asset and the inheritance of value.

(8) Calculation mode. In the big data scenario, one thing is assigned to multiple people. For example, in the MapRece computing framework, a large task will be decomposed into many subtasks and assigned to many nodes for calculation at the same time. In the blockchain scenario, multiple people are allowed to do one thing repeatedly. For example, many nodes in the P2P network record a transaction at the same time.

『2』 Do artificial intelligence, big data, cloud computing, Internet of Things, and blockchain exist independently?

They are not independent entities. Artificial intelligence, big data, cloud computing, the Internet of Things and blockchain are all important development directions in the field of modern information technology, and they are interrelated and mutually reinforcing. Big data provides rich data resources and analysis methods for artificial intelligence, cloud computing and the Internet of Things. The combination of the Internet of Things with cloud computing, artificial intelligence and other technologies can also bring more application scenarios to the industry. Blockchain can provide a more secure and reliable data exchange and management method for the Internet of Things, big data and other fields. These technologies are interdependent and mutually supportive, and their development will have a profound impact on the future development of the entire information technology field.

『三』 Rapid changes in big data, blockchain, cloud technology and other information technology environments have led to changes in auditing that have had an impact on auditors

The impact is as follows:
Replacement of big data auditing Traditional auditing is the general trend. Based on the introduction of technologies such as artificial intelligence and big data, this article proposes five major trends in big data auditing, namely: audit intelligence, audit platformization, multi-dimensional audit information, transformation from sampling audit to detailed audit, and audit visualization. At the same time, this article also points out the five major challenges faced by big data auditing, namely: big data acquisitionThe cost is high, it is difficult to change concepts and habits, talents are scarce, the complexity of the audit business and the design of the big data audit system are complex. The research conclusions of this article have certain reference significance for big data audit practice.
