1. What is the role of blockchain in big data

[Introduction] While big data brings great opportunities to all walks of life, it also brings Many challenges. Blockchain, with its decentralization, trustlessness, high transparency and non-tampering characteristics, can provide higher security, transparency and privacy to big data. So, what are the effects of blockchain in big data?

1. Improving data quality

The essence of blockchain is to remove Centralized distributed ledger. It can also be understood as an tamper-proof, fully historical, distributed database storage technology. Therefore, blockchain technology can liberate more data. The trustworthiness, security, and non-tamperability of blockchain technology fundamentally bring about the improvement of data quality and the enhancement of data verification capabilities.

2. Dealing with the data island problem

Big data has a very serious data island problem, and a lot of data is currently inaccessible. Blockchain is expected to solve this problem. The reason why I say this is mainly because the blockchain is not only a distributed ledger, but also has the characteristics of decentralization and openness. As the maintainers of order 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 issues

In essence, the blockchain is actually a decentralized database. Therefore, if data from a certain node in the blockchain is If there is a change, other nodes will discover it as soon as possible, so the possibility of data leakage will be greatly reduced. Only in the form of a private key can the identity information of each node in the blockchain be successfully obtained, and only the data owner can know the private key.

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

As for the valuable data assets of individuals or organizations, they can be registered using the blockchain, and the transaction records are recorded on the entire network. Recognized, transparent and traceable. Clarifying the source, ownership, use rights and circulation path of big data assets is of great value to the sale and purchase of data assets.

5. Traceability of blockchain

Every step of data collection, transaction, circulation, and accounting analysis can be recorded on the blockchain, thus making Data quality has received unprecedented strong trust endorsement. At the same time, it also ensures the accuracy of data analysis results and the effectiveness of data mining.

The above is all the content that the editor compiled and sent to you today on "What is the role of blockchain in big data?" I hope it will be helpful to everyone. As the saying goes, you won’t fight an unprepared battle if you don’t do it. Generally speaking, with the application of big data in many industries, engineers and developers with big data technology capabilities are very popular.

2. What is the relationship between blockchain and big data?

Blockchain and big data are both hot topics. Many people put them together to discuss and hope to get more hot

points conflict. Big data has become a huge industry long before the development of blockchain. Although blockchain is in the early stages of the

industry, many technologies and business models are still being explored.

In view of the relative maturity of the big data industry, we use big data as a starting point to study how blockchain technology interfaces with all aspects of the big data

industry.

The big data core industry chain can be roughly divided into the following three parts:

Product part: Including big data software product-related industries such as big data basic software and big data application software.

Data part: including data sources (data collection, data provision), data circulation (data transactions, data sharing

) and other industries directly related to data.

Services: related to big data infrastructure services (data storage, data transmission, data cleaning, data desensitization

, etc.), big data analysis services and big data application services services.

01 Product Section

The combination of software products and blockchain should be based on technology. Big data technology and blockchain technology have similarities: they

are distributed architectures.

But they also have obvious differences: the use of distributed technology in big data technology is computing resources - utilizing the computing resources of multiple

machines and will not be used by a single machine Processing tasks are distributed among multiple computers, each

machine. By processing different tasks, it integrates multiple computing resources to form powerful data processing capabilities.

Using distributed technology in blockchain allows multiple entities to trust each other. Each mainframe participates in the operation of the entire blockchain through the computers it controls

. Each computer runs basically the same task, and the entire blockchain

can achieve mutual trust between multiple entities through repeated redundant calculations.

From a technical perspective, big data technology uses trust to exchange computing resources, while blockchain technology uses computing resources to exchange trust. Due to the differences between the two, it is technically difficult to find a suitable collision point between big data and blockchain.

02 Data Part

In the various formats of the data part, the blockchain can find its place.

The chain is of little significance. However, if multiple entities are involved in data collection and data provision, blockchain can

come into its own.

In order to solve the trust problem between multiple entities, each entity broadcasts its own collected data to all consumers

and the hash of that data Values ​​are stored in the blockchain. Based on the hash value on the blockchain, each subject in the blockchain

can verify whether the complete data it received has been tampered with. Blockchain traceability and non-repudiation

make data provided by multiple parties more credible. At the same time, this method also helps maintain the integrity of big data

.

In the data circulation industry, blockchain can play a greater role. In the big data circulation industry, big data itself

is a digital asset. The transaction of digital assets can be realized through the blockchain. Additionally,

decentralized big data transactions implemented on the blockchain can reduce raw data connections. In a decentralized trading platform, only buyers and sellers

have access to the original data; on a centralized trading platform, the data intermediary serving as the trading center usually has access to the original

data. This increases data leakage and assets. Risk of Loss.

03 Service Part

In big data services, the service capabilities as digital assets are the same as the concepts of data and assets in data transactions

and Can be traded.

Blockchain can play an important role in the trading of such digital assets. At the same time, there are many new technologies that are constantly changing the blockchain, such as homomorphic encryption. Homomorphic encryption is an important technology that combines blockchain and big data services

. Homomorphic encryption can truly transform data service functions into digital assets without requiring the big data service provider to copy the original data in the service. risk.

3. How to use big data to promote the development of the blockchain industry in the future

The future regional economic development will focus on four aspects including industrial agglomeration development to further promote the health of the city's blockchain industry Develop rapidly to better serve the digital transformation of the economy and society.

01. Industrial agglomeration development

The blockchain industrial park will be scientifically planned, the park construction will be intensified, the supporting service system will be improved, and the degree of industrial development agglomeration will be enhanced.

02. Increase the introduction and cultivation of blockchain enterprises

Will targetLeading and well-known enterprises in the quasi-international and domestic blockchain field will accelerate the introduction of a group of blockchain companies with strong innovation capabilities and great development potential, support them in setting up R&D centers, project headquarters, etc. in Chongqing, and further gather industrial resources through leading efforts.

03. Promote the completion of demonstration applications of blockchain in key areas

We will strengthen the research and development of key core technologies of blockchain, focusing on breakthroughs in key technologies such as consensus mechanisms, cryptography technology, and smart contracts. .

04. Actively build a good ecosystem for the blockchain industry

We will promote the establishment of a public service platform for the blockchain industry to provide investment and financing, supply and demand docking, etc. for blockchain companies. One-stop service.

4. What is the relationship between blockchain and big data analysis

The relationship between blockchain and big data storage is as follows:

1. Data security: Blockchain allows data to truly flow "with confidence"
With its trustworthiness, security and non-tamperability, blockchain allows more data to be liberated. Let’s use a typical case to illustrate how blockchain promotes the generation of gene sequencing big data. Blockchain sequencing can use private keys to limit access rights, thereby circumventing legal restrictions on individuals' access to genetic data, and utilize distributed computing resources to complete sequencing services at low cost. The security of blockchain makes sequencing an industrialized solution, enabling global-scale sequencing, thus promoting the massive growth of data.
2. Data openness and sharing: Blockchain ensures data privacy
The government holds a large amount of high-density and high-value data, such as medical data, population data, etc. The openness of government data is a general trend and will have an immeasurable impetus to the development of the entire economy and society. However, the main difficulty and challenge in data openness is how to open data while protecting personal privacy. Blockchain-based data desensitization technology can ensure data privacy and provides a solution for data openness under privacy protection. Data desensitization technology mainly uses encryption algorithms such as hashing. For example, the Enigma system based on blockchain technology can calculate data without accessing the original data, which can protect the privacy of data and eliminate information security issues in data sharing. For example, company employees can safely open access to their salary information and jointly calculate the average salary within the group. Each participant is informed of his relative position within the group but not of the compensation of other members.

3. Data storage: Blockchain is an immutable, full-historical, strongly endorsed database storage technology. Blockchain technology is shared by all nodes in the network. Participating in calculations and mutually verifying the authenticity of their information to reach a consensus across the entire network, it can be said that blockchain technology is a specific database technology. So far, our big data is still at a very basic stage. Trusted blockchain data based on the consensus of the entire network is non-tamperable, full history, andThis enables the quality of data to gain unprecedented trust and endorsement, and also brings the development of databases into a new era.
4. Data analysis: Blockchain ensures data security
Data analysis is the core of realizing data value. When conducting data analysis, how to effectively protect personal privacy and prevent core data leakage has become the primary consideration. For example, with the popularization of fingerprint data analysis applications and genetic data detection and analysis methods, more and more people are worried that once personal health data is leaked, it may lead to serious consequences. Blockchain technology can prevent such situations through multi-signature private keys, encryption technology, and secure multi-party computing technology. When the data is hashed and placed on the blockchain, digital signature technology is used to allow only authorized people to access the data. The private key ensures data privacy and can be shared with authorized research institutions. The data is uniformly stored on the decentralized blockchain, and data analysis can be performed without accessing the original data. This can not only protect the privacy of the data, but also safely provide it to global scientific research institutions and doctors for sharing. The basic health database will bring great convenience to solve sudden and difficult diseases in the future.
5. Data circulation: Blockchain protects data-related rights and interests
For individuals or institutions’ valuable data assets, blockchain can be used to register them, and transaction records are recognized and transparent by the entire network. , traceable, clarifying the source, ownership, use rights and circulation path of big data assets, which is of great value to data asset transactions.
On the one hand, blockchain can eliminate the threat of intermediaries copying data and help establish a trustworthy data asset trading environment. Data Chunxin is a very special commodity, which is essentially different from ordinary commodities. It mainly has characteristics such as unclear ownership and "it is owned after seeing it and copying it". This also determines that the transaction method using traditional commodity intermediaries cannot satisfy the data requirements. sharing, exchanging and trading. Because the intermediary center has the conditions and ability to copy and save all the passing Pazhoulun data, this is extremely unfair to the data producers. This threat cannot be eliminated by relying on promises alone, and the existence of this threat has also become a huge obstacle to the flow of data. Based on decentralized blockchain, it can eliminate the threat of data copying by intermediary centers and protect the legitimate rights and interests of data owners.
On the other hand, blockchain provides a traceable path and can effectively solve the problem of data verification. The blockchain jointly participates in the calculation and recording of data through multiple nodes participating in calculations in the network, and mutually verifies the validity of their information. It can not only prevent information counterfeiting, but also provide a traceable path. By stringing together the transaction information of each block, a complete list of transaction details is formed. The ins and outs of each transaction are very clear and transparent. In addition, when people have doubts about the "value" of a certain block, they can easily review historical transaction records to determine whether the value is correct, and identify whether the value has been tampered with or recorded incorrectly.
Everything is guaranteed on the blockchain, and big data will naturally be more dynamicJump up.
The tokens of the crowdfunding projects on the Biying China platform are all developed based on blockchain technology, and relevant information will be recorded on the blockchain.

5. What is blockchain and what is big data

1. Blockchain: It is a computer technology based on distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. New application models. The so-called consensus mechanism is a mathematical algorithm that establishes trust and obtains rights and interests between different nodes in the blockchain system.

Blockchain is an important concept of Bitcoin. The currency jointly released the "2014-2016 Global Bitcoin" by the Internet Finance Laboratory of Tsinghua University PBC School of Finance and Sina Technology. "Coin Development Research Report" mentioned that blockchain is the underlying technology and infrastructure of Bitcoin [2]. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. The blockchain is a series of data blocks generated using cryptographic methods. Each data block contains information about a Bitcoin network transaction and is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

2. Big data: refers to a collection of data that cannot be captured, managed and processed within a certain time range using conventional software tools. It requires new processing models to have stronger capabilities. Massive, high-growth and diversified information assets with decision-making power, insight discovery and process optimization capabilities.

6. How to use big data technology in blockchain technology

Decentralized big data transactions implemented on the blockchain can effectively reduce the number of contacts of the original data. , fundamentally ensuring data security. In the future, Jinwowo will focus on promoting the legal circulation and commercial application of big data using blockchain technology.

7. How do you think big data and blockchain technology may help decision-making?

How big data and blockchain technology may help decision-making:
1. Big data and blockchain technology can help decision-makers analyze data more accurately and make more accurate decisions.
2. Through big data and blockchain technology, market trends can be more accurately understood and more efficient decisions can be made on market conditions.
3. Through big data and blockchain technology, user behavior and big data can be collected more quickly to provide more timely decision support.
4. Through big data and blockchain technology, business processes can be more effectively managed and controlled, resulting in more effective decision-making.

8. What is the relationship between blockchain and big data?

Blockchain and big data are both hot topics. The development of big data precedes the development of blockchain. Chain has now become a huge industry, and combining the developing blockchain technology with big data will produce different effects. From a technical perspective, big data technology exchanges trust for computing resources, while blockchain technology exchanges computing resources for trust, so the combination of the two has set offThe 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 professionally provide blockchain as the underlying technology. big data services.
