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 a way to 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, there is no battle without preparation. Generally speaking, with the application of big data in many industries, engineers and developers with the ability to work in big data technology are very popular.

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

Big data can be placed on the word data, which is generated by various social activities. Blockchain is an underlying technologytechnology, just like the Internet. However, it regards the Internet as its bottom layer and builds a blockchain network on the bottom layer of the Internet. Many people also call it the "Internet of Value."
As for the connection, big data can be combined with blockchain technology. For example, blockchain has traceability features. When a big data package is traded on the blockchain network, it can be seen on the entire network. flow direction. Able to confirm and track the data package

3. Big data and blockchain

This story still starts with Bitcoin

Bitcoin, the electronic cash system, is both disintermediated (electronic cash between individuals does not require the intervention of a trusted third-party intermediary) and decentralized (maintained by an institution) (both parties to the transaction can operate without establishing trust). Complete the transaction based on the relationship)

Hash function: Convert any long string into a fixed-length output (the calculation process cannot be too complicated), as long as the input string changes slightly, the hash function The output of the 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. Blockchain system ensures security, 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) means consistency, which means that any read operation can always read the result of the 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 still 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.

4. How Jinwowo combines blockchain and big data

To put it simply, blockchain and big data are hot topics, and the development of big data Earlier than blockchain, it has now become a huge industry. 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 off a new wave of information security.

Based on the characteristics of blockchain distributed data storage, decentralization, non-tampering, traceability, and trustworthiness, Jinwowo Network Technology Group has established a strong blockchain research team. Currently, Jinwowo has applied for 3 blockchain patent technologies. In the future, Jinwowo Group will conduct in-depth research on big data services with blockchain as the underlying technology, and strive to build a platform for communication between individuals and enterprises.Credit relationships, precipitate credit data, provide solutions for enterprise business model design and precision marketing, and promote the development of the Internet and even the entire social credit system.

5. Title: With the help of big data and blockchain, what do you think the future development model of the accounting information system should be?

The connection with other subsystems has been strengthened, and it has become more and more important to enterprise management. Information systems move closer.
With the development of computer technology, big data and blockchain, two of the most eye-catching cutting-edge technologies nowadays, are gradually being applied in practice. As one of the indispensable professions in any industry, accounting is bound to be affected by these two emerging technologies. Big data technology has caused an explosive growth in the quantity of accounting information, and the birth of blockchain technology has improved the accuracy of information. Therefore, the accounting profession will usher in new developments in breadth and accuracy.
With the emergence of paperless accounting, accounting computerization is widely used in various enterprise management and settlement services. Kingdee UFIDA and other similar software came into being. By setting login identities and permissions, and directly entering relevant transaction capital business and other matters on the network management platform, work efficiency is greatly improved. The computerized accounting software uses a large and stable database, and the financial system is constructed in a modular manner, making the accounting more standardized and the management level of the enterprise improved. At the same time, ERP systems also have many shortcomings. However, the upgrading of accounting software is far behind the innovation of computing and computer systems, and the stagnation of accounting software development has largely restricted the further development of the entire financial accounting industry. Second, employees must log in to the accounting information system through encrypted login methods. However, it is still unavoidable that some criminals can steal the operator's login password to conduct illegal operations and forge accounting data, which lacks authenticity during the current operation. Log monitoring cannot effectively prevent this behavior. Third, the professional module processing is not targeted and the operation is too cumbersome. The query and inventory are rough and prone to errors and omissions. Fourth, the calculation method of cost, depreciation and depreciation apportionment is accurate in calculation but in fact the method is extensive and the workload is large. Whether it is manual accounting or computerized accounting, the inability to obtain relatively accurate product costs in a timely manner has not solved the problem of data.

6. 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

We will target leading and well-known enterprises in the international and domestic blockchain field and accelerate the introduction of a group of innovative and developing companies. Blockchain companies with great potential will be supported in setting up R&D centers, project headquarters, etc. in Chongqing, throughThe leading role drives further gathering of industrial resources.

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.

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

There is a common keyword between big data and blockchain: distributed, which represents a The transformation from technical authority monopoly to decentralization.

Distributed storage: HDFS vs. block

Big data needs to cope with massive and rapidly growing storage, which requires underlying hardware architecture and files The system is much more cost-effective than traditional technology and can flexibly expand storage capacity. Google's GFS and Hadoop's HDFS lay the foundation for big data storage technology. In addition, another challenge that big data poses to storage technology is the adaptability of multiple data formats. Therefore, the underlying storage layer of big data is not only HDFS, but also storage architectures such as HBase and Ku.

Blockchain is the underlying technical architecture of Bitcoin. It is essentially a decentralized distributed ledger. Blockchain technology is a continuously growing chain data structure organized into blocks in sequence. Multiple nodes in the network jointly participate in the calculation and recording of data, and mutually verify the validity of their information. From this point of view, blockchain technology is also a specific database technology. Due to the security and convenience of decentralized databases, many people in the industry are optimistic about its development and believe that it is an upgrade and supplement to existing Internet technology.

Distributed Computing: MapRece vs. Consensus Mechanism

Big data analysis and mining is data-intensive computing and requires huge distributed computing capabilities. Node management, task scheduling, fault tolerance and high reliability are key technologies. Google and Hadoop's MapRece are representatives of this distributed computing technology. By adding server nodes, the total processing capacity of the system can be linearly expanded (Scale Out), which has huge advantages in cost and scalability. Now, in addition to batch computing, big data also includes computing frameworks such as stream computing, graph computing, real-time computing, and interactive query.

The consensus mechanism of the blockchain is how all distributed nodes reach a consensus, generate and update data through algorithms, and determine the validity of a record. This is not only a means of identification, but also a way to prevent tampering. s method. Blockchain mainly includes four different consensus mechanisms, which are suitable for different application scenarios and strike a balance between efficiency and security. Taking Bitcoin as an example, it uses "Proof of Work"k, referred to as POW), it is only possible to forge a non-existent record if it controls more than 51% of the accounting nodes in the entire network.

# Seize every opportunity to cooperate with China#

With the development of the economy, the original financial system full of middlemen has Obvious problems have arisen, and inherent flaws and systemic risks in global economic governance continue to expand. Against this background, technological advancements and changes in financial solutions in the digital era provide a new perspective on the transformation of global economic governance.

Blockchain, as a framework underlying technology, can make use of technologies such as encrypted chain block structure, peer-to-peer network, distributed algorithm and data cloud storage, suggesting a more open and transparent , a financial system that is more easily accessible and creates new connection methods and business models.

GG56’s BTour Chain project is based on blockchain technology and is committed to improving the efficiency and effectiveness of the tourism industry, improving the structural problems of the tourism industry, promoting emerging tourism culture and donation culture, and aims to create a A new tourism ecology. Through technological innovation and the perfect integration of "blockchain + big data", GG56 will expand new application areas.

In the blockchain industry, China has always maintained an absolute leading position. On October 24, China’s national leaders emphasized at the 18th collective learning meeting that blockchain should be used as an important breakthrough for independent innovation of core technologies and accelerate the development of blockchain technology and industrial innovation; on October 28, China The central bank took the lead in launching the digital currency DCEP. A series of measures are announcing to the world China’s strength and determination to enter the blockchain industry. We need to seize every opportunity to cooperate with China.

Although blockchain technology can improve the problem of middlemen in the traditional financial model, blockchain data is native and cannot directly receive external data. Between the public chain and the alliance chain, the alliance chain and the alliance chain are like a parallel world, unable to produce fast interactive behaviors, resulting in the inability to transfer value in the blockchain system. This situation has led to new problems - —Blockchain value island.

The problem of value islands has inhibited the development of blockchain technology. How can blockchain technology maximize its financial utility? The emergence of a new hybrid chain architecture is particularly important and urgent. Against this background, GMPC founder Brain proposed the concept of hybrid chains and created the world's first multi-chain compound hybrid chain GMPC. Based on the first MixLink protocol, GMPC delivers traffic and exchanges assets to value islands in the blockchain, and ultimately realizes public chains, alliance chains, and even It is the interconnection of assets between cross-chains, striving to overcome the value island of blockchain and achieve the interconnection of all things.

#GMPC conquers the island of value in blockchain#

GMPC hybrid chain is committed to creating a scalable container, between GMPC and external When the external links interact, the external links do not need to change the original technical architecture. The purpose of interconnection and interoperability is achieved on the premise of respecting the original architecture of Wanlian as much as possible.

GMPC’s core technical architecture mainly includes three technical components: the first core component is the consensus language, which supports Turing complete language, etc.; the second GMPC’s TOKEN economic model and JBFT consensus mechanism are We improved the consensus mechanism based on the BFT consensus mechanism;

The third is the Mixlink protocol, which includes three levels of protocols: the first layer of protocols is the basic application traffic distribution protocol, Many Internet APPs and blockchain DAPPs can be connected to the hybrid chain ecosystem and distributed using the basic traffic distribution protocol; secondly, it also has an interaction protocol with external links, through which assets and information can be reached with external links The purpose of interoperability; the third is the value circulation agreement, which classifies different consensus mechanism external links and then summarizes them into the same multi-command, which can effectively improve efficiency. The third is the Mixlink protocol. This protocol includes three levels of protocols: The first level protocol is the basic application traffic distribution protocol, which can connect many Internet APPs and blockchain DAPPs to the hybrid chain ecosystem and utilize basic traffic. Distribution agreement for distribution; secondly, it also has an interaction agreement with external links, through which the purpose of asset and information exchange can be achieved with external links; the third is the value circulation agreement, which classifies external links with different consensus mechanisms, and then Boiled into the same multiple commands, this can effectively improve efficiency.

#GMPC and GG56 signed a strategic cooperation agreement#

GMPC Hybrid Chain takes promoting the development of the blockchain industry as its own responsibility and promotes the development of the blockchain industry. As its mission to promote the good development of new financial models through chain ecology, GMPC Hybrid Chain’s solid blockchain technology has been highly praised by Han Seung-soo, former Prime Minister of South Korea and Chairman of the 56th United Nations General Assembly.

As the only South Korean project that won the bid under the strategic deployment of the Belt and Road Initiative, GMPC Hybrid Chain will work with the Guangzhou Municipal Government and the International Financial Forum to jointly build Nansha International Financial City and actively promote the Belt and Road Initiative.implement strategic projects to safeguard and develop the economies of China and South Korea.

In the golden age of blockchain development, cooperation can lead to win-win results. On January 4, 2020, the G Pay Global Launch Conference and Cooperation Strategy Signing Conference concluded successfully in Qingdao. GMPC founder Brian CHOI and GG56 China President Shen Zaiyuan were invited to attend the conference and deliver speeches. Witnessed by the guests present, GMPC founder Brian CHOI and GG56 China President Shen Zaiyuan signed a strategic cooperation agreement.
