Understanding of big data and blockchain

1.

1. blockchain: it is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

blockchain is an important concept of bitcoin. According to the 2014-2016 global bitcoin Development Research Report issued by the Internet Finance Laboratory of Wukou School of finance, Tsinghua University and Sina Technology, blockchain is the underlying technology and infrastructure of bitcoin [2]. In essence, it is a decentralized database, as well as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

2. Big data: refers to the data set that cannot be captured, managed and processed by conventional software tools within a certain period of time. It is a massive, high growth rate and diversified information asset that needs new processing mode to have stronger decision-making power, insight and discovery power and process optimization ability

2. It's not the same thing
big data refers to the technical difficulties caused by too much data, mainly 4V, large amount of data, fast data generation, diverse data formats and low data value
there are many corresponding technical problems to be solved
blockchain is a technical term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance".

3. The decentralized big data transaction realized on the blockchain can effectively rece the contacts of the original data and fundamentally guarantee the security of the data
in the future, jinwowo will focus on blockchain technology to promote the legal circulation and commercial application of big data.

4. The relationship between Chongqing jinwowo analysis blockchain technology and big data is as follows:
the relationship between blockchain and big data is not very big. The main purpose of big data is to manage massive data, and the core of blockchain is to achieve high security and high reliability of data without centralized intermediary accounting
therefore, blockchain and big data do not conflict with or replace each other. They are completely different solutions for data in different scenarios.

5. Chongqing jinwowo analysis: with its trustworthiness, security and non tamperability, blockchain liberates more data and promotes the massive growth of data.

6. Blockchain and big data are hot topics. The development of big data is earlier than that of blockchain. At present, it has become a huge instry. The combination of developing blockchain technology and big data will bring about different effects. From a technical point of view, big data technology exchanges computing resources with trust, while blockchain technology exchanges computing resources with trust, so the combination of the two sets off a new wave of information security. Based on the characteristics of blockchain distributed data storage, decentralization, non tampering, traceability and trustworthiness, Chongqing jinwowo network technology group has established a strong blockchain research team to provide big data services with blockchain as the underlying technology.

7. Big data is a huge data group collected from many sources in multiple forms, often with real-time. In the case of business to business sales, the data may come from social networks, e-commerce websites, customer visit records, and many other sources. These data are not the normal data group of the company's customer relationship management database. From a technical point of view, the relationship between big data and cloud computing is as inseparable as the positive and negative sides of a coin. Big data can not be processed by a single computer, so it must adopt distributed computing architecture. It is characterized by massive data mining, but it must rely on cloud computing distributed processing, distributed database, cloud storage and / or virtualization technology. The meaning of big data is accompanied by the increasingly popular network behavior of human beings. It is collected by relevant departments and enterprises, and contains the real intention and preference of data procers. It is non-traditional structure and meaning of data.

8. If you don't understand this, don't do it. It's all virtual things. When the landlord asks questions, it's deceptive. It's obvious that those who advertise on this platform value your principal

9. As the two major trends in the development of the Internet, blockchain and big data not only have a strong driving force for the rapid development of enterprises, but also play a great positive role in reshaping the social integrity system

through the blockchain, jinwowo Group believes that the blockchain can not only trace the source of every commodity on the platform, ensure the quality of commodities, but also record the real behavior of every user on the platform, so as to enhance the integrity constraints of online behavior; Moreover, these behavior data can be reasonably and legally applied through the characteristics of blockchain itself.
