1. Jinwowo analysis believes that blockchain mainly solves the trust and security problems of transactions. Once the information is confirmed and added to the blockchain, it will be permanently stored. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of data on a single node cannot be realized. Therefore, the data stability and reliability of blockchain are very high
e to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of each node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system.

2. More and more enterprises join the team of digital transformation, how to effectively protect data security will become the core competitiveness of this era. In 2012, the newly revised "Civil Procere Law" and "Criminal Procere Law" officially included electronic data in the legal classification of evidence, the relevant laws and regulations of electronic data began to be promulgated, and electronic data began to move towards the historical stage
however, in view of the characteristics of electronic data, such as reprocible, easy to tamper, difficult to confirm, difficult to provide evidence and so on, electronic evidence urgently needs a professional, reliable and judicial credible technology to effectively solve the trust problem of electronic evidence
blockchain has the advantages of decentralization, distributed accounting, encryption and traceability, which can ensure the integrity and authenticity of data on the chain. Once it is tampered or forged, it can be found. At the same time, because the blockchain has the characteristics of Distributed Accounting, even if the data on indivial nodes are deleted, other nodes can still save the data completely, ensuring the normal operation of the whole blockchain storage system
in 2018, the supreme law of the people's Republic of China clearly pointed out in the provisions on Several Issues concerning the trial of cases by Internet courts that the electronic data submitted by the parties can be verified by electronic signature, trusted time stamp, hash value verification, blockchain and other technical means of evidence collection, fixation and tamper proof, or by electronic forensics storage platform authentication, The Internet court should confirm. This is the first time that the legal effect of blockchain technology in electronic data is affirmed from the judicial level
based on the above advantages, blockchain is naturally suitable for electronic data storage. The introction of blockchain can effectively solve the authenticity and legitimacy of electronic evidence and make the process of electronic data storage more reliable. By using blockchain technology, easyprotection can solve the whole link trustworthiness problems of electronic data, such as generation, certificate storage, notarization and evidence proof; After being linked, each judicial node in the security chain is used to ensure the credibility and security of the data; In litigation, evidence goes directly to the Internet court to improve the efficiency of rights protection.

3. In one sentence, it is decentralization
blockchain 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
in a narrow sense, blockchain is a kind of chain data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography
broadly speaking, blockchain technology is a new distributed infrastructure and computing method, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data< Advantages:
1) the algorithm is simple and easy to implement
2) there is no need to exchange additional information between nodes to reach a consensus
3) it takes a lot of cost to destroy the system< Disadvantages:
1) waste of energy
2) it is difficult to shorten the block confirmation time
3) the new blockchain must find a different hash algorithm, otherwise it will face bitcoin attack
4) it is easy to generate bifurcation and needs to wait for multiple confirmations
5) there is no finality, and checkpoint mechanism is needed to make up for it.

4. The art instry
ascribe allows artists to declare ownership by using blockchain technology, issue numbered, limited edition works, and target any type of art in digital form. It even includes a trading market where artists can buy and sell through their websites without any intermediary services<
in the legal instry
bitproof is the most advanced of many document timestamp applications emerging in recent years, which will make the traditional notarization method a thing of the past. Bitproof offers more services than free versions including blocksgin and originstaemp, including one for intellectual property. Interestingly, bitproof recently cooperated with an it school in San Francisco to put their students' academic certificates on the blockchain, completely redefining how to handle and use diplomas and student certificates<
development instry
colu is the first enterprise to allow other enterprises to issue digital assets. Many people are impressed that they can "token" all kinds of assets. Although the free bitcoin wallet couperparty also allows simple tokens to be issued and traded among other wallet holders, the tokens of colu can be set with various states and types, can be detached from or returned to the system, and can be stored on BitTorrent's network when the data stored on the blockchain is too large<
the real estate instry
they plan to modernize the whole instry chain process and solve various problems faced by everyone when participating in real estate, including naming process, land registration, agency, etc
viewing blockchain from a financial perspective
the essence of money: money is just a kind of broad value consensus, and it does not have value precipitation
the relationship between assets and currency: currency describes assets
what is digital assets: assets are digital, segmentable and tradable, and the price is determined by the supply and demand market, not by the value intermediary currency<
Internet of things
application scenario analysis [7]
a possible application scenario is: generate corresponding behavior through transaction, assign address to each device, inject a certain fee into the address, and perform relevant actions, so as to achieve the application of Internet of things. Similar to: PM2.5 monitoring point data acquisition, server leasing, webcam data call, DNS server, etc
in addition, with the increasing number of Internet of things devices and the increasing demand for edge computing, a large number of devices need to adopt a distributed self-organization management mode, and the requirement for fault tolerance is very high. The distributed and anti attack characteristics of blockchain can be well used in this scenario
IBM [7]
IBM has continuously invested in the research and development of the Internet of things for decades, and is exploring the use of blockchain technology to rece the cost of Internet of things applications
in early 2015, IBM and Samsung announced their cooperation in developing adept system
logistics supply chain [7]
the supply chain instry often involves many entities, including logistics, capital flow, information flow, etc. there are a lot of complex cooperation and communication between these entities. Under the traditional mode, different entities keep their own supply chain information, which is seriously lack of transparency, resulting in higher time cost and money cost, and it is difficult to trace and deal with problems (false claim, counterfeit goods, etc.)
through the blockchain, all parties can obtain a transparent and reliable unified information platform, which can view the status in real time, rece the logistics cost, and trace the whole process of proction and transportation of goods, so as to improve the efficiency of supply chain management. When disputes arise, the proof and tracing become clearer and easier
this field is considered as a promising application direction of blockchain
for example, the carrier can scan the QR code to prove that the goods arrive at the designated area, and automatically charge the fees agreed in advance. We can refer to how the blockchain changes the supply chain finance and brings transparency to the supply chain
skuchain creates a new supply chain solution based on blockchain to realize the synchronization of commodity flow and capital flow, and alleviate the problem of counterfeit goods
public network service [7]
the normal operation of the existing Internet is inseparable from many nearly free network services, such as domain name service (DNS). Anyone can query the domain name for free. Without DNS, all kinds of websites can't be accessed. Therefore, for the network system, similar basic services must be safe, reliable and low-cost
blockchain technology just has these characteristics. The DNS system based on blockchain will no longer have all kinds of wrong query results, and can provide services stably and reliably
Insurance Instry
in the past two years, the hottest topic in the field of science and technology can not be separated from blockchain technology. This underlying technology, born out of bitcoin, has proved its highly secure and reliable architecture and algorithm design with more than seven years of stable operation. At the same time, with innovative technologies such as distributed ledger and smart contract, it has opened up a huge imagination space for instrial upgrading of many instries. Some instry experts even predict that blockchain technology will set off the second Internet revolution
the financial instry has always been the most sensitive to advanced technology. Traditional banking and securities giants have been investing in blockchain venture capital since 2014. In two years, the total global investment is as high as US $1 billion, and there is no lack of a-round financing such as US $60 million of Dah and US $50 million of blockstream. In addition to capital investment, major companies have personally participated in and promoted specific business applications: for example, the LINQ blockchain equity exchange launched by the Nasdaq Stock Exchange in the United States has started issuing tests at the end of 2015; The R3 CEV alliance formed by 43 multinational banks in the world has been testing and improving the inter-bank clearing alliance chain, with unprecedented speed and participation
although the insurance instry's participation in blockchain technology is relatively conservative, it has been actively exploring and researching in the academic field. At the end of 2014, the 50 page "lifelong chain" special research report launched by the European and American insurance instry forum initiated by the famous Z / yen Group Consulting Group in the UK discussed the innovation and change that blockchain will bring to the insurance instry from many aspects
while studying blockchain technology, I have exchanged with many domestic experts and scholars in the insurance instry, and deeply discussed the specific foothold of blockchain in the insurance business from the perspectives of business process and company management. Now I share with readers some thoughts on credit risk management.

6. Chongqing jinwowo analyzes and solves problems in the following ways:
first of all, by using all data chains in the blockchain for prediction and analysis, the regulatory authorities can timely discover and prevent possible systemic risks. The decentralized characteristics of the blockchain can eliminate the information island in big data risk control, and improve risk control through information sharing
secondly, the distributed database of blockchain can improve the poor quality of big data risk control data, and solve the problems of data format diversification, data form fragmentation, lack of effective data and incomplete data content
finally, blockchain can prevent data leakage. Because the blockchain database is a decentralized database, any node's operation on data will be found by other nodes, thus strengthening the monitoring of data leakage.

[guide] while big data brings great opportunities to all walks of life, it also brings many challenges. Blockchain, with its characteristics of decentralization, distrust, high transparency and no tampering, can be considered that big data is endowed with higher security, transparency and privacy. So what are the effects of blockchain in big data
first, improving 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
IV. 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
data can be stored in the blockchain from every step of collection, trading, circulation, and accounting analysis, 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
the above is Xiaobian's "what is the role of blockchain in big data?" I hope it can help you. In general, with the application of big data in many instries, engineers and developers with big data technology are very popular
