Big data on 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. 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.

3. 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.

4. Blockchain technology brings new growth possibilities to these fields. For example, in the insurance field, combined with blockchain technology, we can see growth opportunities for reinsurance in the future; In the field of health care, the integration of medical data and file management can also be realized through distributed ledger technology; The combination of supply chain and blockchain technology will create more financing opportunities
all of the above are potential application fields of blockchain technology, but if the first large-scale application field of blockchain technology, I think it will be in the fields of insurance and health care
because the current data in these two fields are very scattered and chaotic, they can be integrated systematically through blockchain technology. In the future, a lot of business opportunities can be found after specific analysis of these data
some excellent digital currencies have begun to appear in China, such as Puyin, a tea standard digital currency launched by Puyin group. Puyin is a high-quality Tibetan tea asset that is stored, identified, evaluated and authorized by three parties, and a standard digital currency that is issued through encryption and digitization.

5. 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.

6. The relationship between blockchain and big data storage is as follows:
first, data security: blockchain makes data flow "at ease"
with its trustworthiness, security and non tamperability, blockchain liberates more data. A typical case is used to illustrate how blockchain promotes the generation of big data for gene sequencing. Blockchain sequencing can use the private key to limit access rights, so as to avoid the legal restrictions on indivial access to gene data, and use distributed computing resources to complete the sequencing service at low cost. The security of blockchain makes sequencing an instrialized solution, realizing global scale sequencing, thus promoting the massive growth of data< Second, data open sharing: blockchain guarantees data privacy
the government has a large number of high-density and high-value data, such as medical data, population data, etc. The opening of government data is the general trend, which will have an inestimable impetus to the development of the whole economy and society. However, the main difficulty and challenge of data opening is how to open data while protecting personal privacy. Data desensitization technology based on blockchain can ensure data privacy and provide a solution for data opening under privacy protection. Data desensitization technology mainly uses hash processing and other encryption algorithms. For example, enigma based on blockchain technology can protect the privacy of data and eliminate information security problems in data sharing by computing data without accessing the original data. For example, employees of a company can safely open the path to access their salary information and jointly calculate the average salary within the group. Each participant can know his or her relative position in the group, but he or she knows nothing about the salaries of other members< The schematic diagram of data hash desensitization processing
3. Data storage: blockchain is a kind of database storage technology that can not be tampered with, full history, strong endorsement
blockchain technology, through all nodes in the network participate in the calculation together, and verify the authenticity of their information to achieve the consensus of the whole network, it can be said that blockchain technology is a specific database technology. So far, our big data is still in a very basic stage. The data based on the consensus of the whole network and the reliable blockchain data are tamperable and historical, which makes the quality of the data gain unprecedented strong trust endorsement, and also makes the development of the database enter a new era< Data analysis: blockchain ensures data security
data analysis is the core of realizing data value. In data analysis, how to effectively protect personal privacy and prevent core data leakage has become the primary consideration. For example, with the application of fingerprint data analysis and the popularization of genetic data detection and analysis, more and more people worry that once personal health data is leaked, it may lead to serious consequences. Blockchain technology can prevent this kind of situation through multi signature private key, encryption technology and secure multi-party computing technology. When the data is hashed and placed on the blockchain, the use of digital signature technology can enable those authorized people to access the data. The private key not only ensures the privacy of data, but also can be shared with authorized research institutions. The data is stored on the decentralized blockchain and analyzed without accessing the original data. It can not only protect the privacy of the data, but also provide it to the global scientific research institutions and doctors for sharing. As the basic health database of all mankind, it will bring great convenience to solve the sudden and difficult diseases in the future
v. data circulation: blockchain protects the rights and interests related to data
for valuable data assets of indivials or institutions, blockchain can be used to register them. Transaction records are recognized, transparent and traceable throughout the network, making clear the source, ownership, use right and circulation path of big data assets, which is of great value to data asset transaction
on the one hand, blockchain can break the threat of intermediary ing data, which is concive to the establishment of a trusted data asset trading environment. Data is a very special commodity, which is essentially different from ordinary commodities. It is mainly characterized by unclear ownership and "being owned after seeing and ing", which also determines that the traditional commodity intermediary transaction method can not meet the needs of data sharing, exchange and transaction. Because the intermediary center has the conditions and the ability to and save all the flowing data, it is extremely unfair to the data procers. This threat can not be eliminated only by commitment, and the existence of this threat has become a huge obstacle to the flow of data. Based on the decentralized blockchain, it can break the threat of ing data in the intermediary center and protect the legitimate rights and interests of data owners
on the other hand, blockchain provides a traceable path, which can effectively solve the problem of data right confirmation. Through multiple nodes participating in the calculation in the network, blockchain can participate in the calculation and recording of data together, and verify the effectiveness of their information. It can not only carry out information anti-counterfeiting, but also provide a traceable path. The transaction information of each block is strung together to form a complete detailed list of transactions. The context of each transaction is very clear and transparent. In addition, when people have doubts about the "value" of a block, they can easily trace back the historical transaction records, and then judge whether the value is correct, and identify whether the value has been tampered or recorded incorrectly
with the protection of blockchain, big data will naturally become more active
the tokens of crowdfunding projects on coin Ying China platform are all developed based on blockchain technology, and relevant information will be recorded on the blockchain.

first, improve data quality

the essence of blockchain is a decentralized distributed ledger. It can also be understood as a non tampering, full history, distributed database storage technology. Therefore, blockchain technology can liberate more data. The trustworthiness, security and non tampering of blockchain technology fundamentally improve the quality of data and enhance the ability of data inspection

Second, dealing with the problem of data island

big data has a very serious problem of data island, and a lot of data cannot be obtained at present. Blockchain is expected to deal with this problem. This is mainly because blockchain is not only a distributed ledger, but also has the characteristics of decentralization and openness. As order maintainers in the financial market, regulatory organizations can also predict and analyze possible dangerous problems through the data chain in the blockchain

3. Dealing with data leakage

in essence, the blockchain is actually a decentralized database. Therefore, if the data of one node in the blockchain changes, other nodes will find it at the first time, so the possibility of data leakage will be greatly reced. Only in the form of private key can the identity information of each node in the blockchain be obtained successfully, and only the data owner can know the private key

4. Blockchain can protect the relevant rights and interests of data

for valuable data assets of indivials or organizations, blockchain can be used to register them, and transaction records are recognized, transparent and traceable throughout the network. The source, ownership, use right and circulation path of big data assets are clear, which is of great value to the transaction of data assets

v. traceability of blockchain

every step of data collection, trading, circulation, and accounting analysis can be kept on the blockchain, so that the data quality can obtain unprecedented strong trust endorsement. At the same time, it also ensures the correctness of data analysis results and the effect of data mining
