1. As a kind of decentralized database, blockchain has the characteristics of openness, distribution and irreversibility. As an electronic data storage platform, blockchain has the advantages of low cost, high efficiency and stability. At present, blockchain has been applied in many fields and has brought many changes to our life. Now many electronic contract platforms, such as Fada This kind of blockchain technology has been applied in the chain of evidence, and the blockchain technology has also been accepted by the court
2. 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.
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.
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. 1. What is blockchain? In a word
A: blockchain is an encrypted database chain, that is, the transaction data in multiple timestamps / events are encrypted and linked together, and the data can not be tampered with or shared
2. Performance and logic:
A. external operation forms: bank deposit and withdrawal, remittance, account in and out, shopping, currency issuance, capital transaction, etc
B. internal logic processing (software program): after human operation, the data will be encrypted first and then stored in the database. After the program, the data will be divided into regions, such as the data in the event and time stamp will be classified and put together into a region. Multiple events and data in timestamps are associated to form a blockchain. The encrypted data can be shared, but not tampered with
C. forms of sharing: querying personal information, auditing, etc. Query permission / sharing permission: different permissions can query different data. For example, the bank can query the information of all people, and the indivial can only query the indivial
3. Most of the examples are different, but the logic processing ideas are the same, but the implementation methods and operations are different
4. Blockchain: it has the characteristics of encrypted data, tamperable data and shared data
5. Blockchain Technology: the technology of encrypting, partitioning and sharing data with editing programs
there are suggestions for guidance
application fields: finance, it, commodity sales, online shopping, etc.

5. Personal social security can only be paid in the place where the account is located. Go to the local social security account and bind the bank card. Non local indivials can not pay, only through the company
6. Blockchain has a high degree of technical security and broad technology prospects. It is still in continuous development, improving enterprise efficiency and recing operating costs, and will graally be promoted and applied in other fields and instries
Renren chain is an enterprise level platform service based on mainstream blockchain technology, which can help you quickly build a more secure and stable blockchain environment, rece challenges in blockchain deployment, operation and maintenance, and development, and enable you to focus more on core business innovation, so as to realize fast business on the chain
in the current enterprise management mode, no matter customer relationship management, project management, procurement management, human resource management, there are data security and reliability problems to some extent. For example, sometimes transaction data under the market mechanism is untrue / fake / deleted and changed, and some problems such as making ill considered decisions e to data resource blocking occur, In the long run, it will cause harmful business impact on enterprises. Moreover, some enterprise systems are lack of real-time tracking in the process of the project, which is prone to data disorder and lag, resulting in the inability to timely monitor the project and track the responsibility, low management efficiency and so on, which can be avoided in the early selection of enterprises!

7. To answer this question, let's first introce the core technology of blockchain and the current insurance instry<
Introction to the core technology of blockchain
blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
the first one is called distributed ledger, which is that transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, Therefore, they can participate in the supervision of the legitimacy of the transaction, but also can jointly testify for them. Different from the traditional centralized accounting scheme, no single node can record accounts separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. On the other hand, because there are enough accounting nodes, in theory, unless all nodes are destroyed, the accounts will not be lost, thus ensuring the security of the account data
the second is called symmetric encryption and authorization technology. The transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
the third mechanism is called consensus mechanism, which is how to reach a consensus among all accounting nodes to determine the validity of a record. This is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes to join the blockchain, this is basically impossible, thus eliminating the possibility of fraud
the fourth technical feature is called smart contract, which is based on these trusted and tamperable data and can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts<
risk management of policyholders
in the current insurance business, disputes between insurance companies and policyholders occur from time to time, either the policyholders provide false personal information to defraud insurance, or there are differences in the determination of exemption clauses when settling claims. The key to these problems lies in the lack of a real and reliable data collection and storage means for the personal information of the insured
with the advancement of national systematic projects such as medical information digitization and personal credit system, more and more authoritative data sources appear. If these data can be introced and stored on the blockchain, it will become the digital identity of everyone. The data above is authentic, can't be tampered with, real-time synchronization and life-long validity, It will bring great benefits to the risk management of the insured
the first is to get through the data between different companies and refer to each other, so as to discover the information of repeated insurance and historical claims in time, and discover high-risk users in time
secondly, introcing data from different instries into the blockchain can improve the accuracy and efficiency of underwriting and claims verification. For example, if you can query all the medical records of the insured, even the medical records of the immediate family members, on the blockchain, you will have first-hand information about the current physical condition, disease history and family history of the insured, effectively eliminating the insurance with diseases
for example, at present, China's first network mutual aid platform using blockchain technology as the core is concentric mutual aid. On the basis of traditional mutual aid platform, with the help of blockchain technology, it realizes decentralized information sharing, innovates and realizes comprehensive and transparent operation, and builds a fair, just, open, safe and efficient open mutual aid information service platform for the public.

8. I choose Chinese currency! Low operation delay, idle can also save money mining EOS, very suitable.
9. 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.

10. To answer this question, let's first introce the advantages and disadvantages of network mutual assistance and the advantages of applying blockchain technology
advantages of online mutual assistance:
online mutual assistance is actually a variant of foreign mutual insurance (or mutual insurance) in China. It inherits the characteristics of some modes of mutual insurance, such as organizational form and management methods. It also makes some changes according to the characteristics of China's insurance market and the current regulatory environment
Internet Mutual Aid relies on the Internet's efficient information matching ability, convenient payment service and low entry threshold, Therefore, network mutual aid has the ability to gather a large number of members in a short time
low cost
at least 50% ~ 80% cheaper than the traditional security scheme
high participation
the value provided by network mutual aid is easily accepted by users
flexible security
flexible procts, It can launch mutual aid procts for all kinds of people
shortcomings of online mutual aid:
operation is not transparent
there may be problems such as platform fabricating mutual aid events to obtain users' funds
user privacy
the general carrier of online mutual aid platform is technology company, which lacks supervision and public trust endorsement, Therefore, it is easy to be questioned
inefficient
compensation process is slow
Application of blockchain technology
we think that the emergence of blockchain technology provides solutions to these problems. The network mutual aid application based on blockchain platform can maximize the absolute security of funds, protocols and information, and improve the risk control ability
the flow of funds is transparent
all the details of the flow of funds are recorded on the blockchain, and the data can not be forged or tampered to ensure the authenticity and validity of the data. All regulatory units, public media and ordinary users can view and supervise the implementation of the rules at any time
the rules are efficient
all the funds are transferred according to the open and tamperable smart contract, Once determined, it can be executed accurately, no one can intervene, no legal person can misappropriate or intervene, which improves the efficiency of rule execution
user information security
all personal sensitive information is highly encrypted and stored, unless authorized by the user, Other people can't access and steal
the service will never be down
the network mutual assistance running on the public chain does not depend on whether a central server is online, which can ensure that the service provided will never be down
in the current insurance business, disputes between insurance companies and policy holders occur from time to time, or the policy holders provide false personal information to cheat insurance, Or there are differences in the determination of the exemption clause when settling the claim. The key to these problems lies in the lack of a real and reliable data collection and storage means for the personal information of the insured
with the advancement of national systematic projects such as medical information digitization and personal credit system, more and more authoritative data sources appear. If these data can be introced and stored on the blockchain, it will become the digital identity of everyone. The data above is authentic, can't be tampered with, real-time synchronization and life-long validity, It will bring great benefits to the risk management of the insured
the first is to get through the data between different companies and refer to each other, so as to discover the information of repeated insurance and historical claims in time, and discover high-risk users in time. Taking the 40 million accident insurance fraud in March this year as an example, Zhou of Yangzhou took out insurance in more than ten life insurance companies, which was not found out until the manual underwriting. If every insurance information is recorded in the blockchain, it can be found and timely measures can be taken
secondly, introcing data from different instries into the blockchain can improve the accuracy and efficiency of underwriting and claims verification. For example, if you can query all the medical records of the insured, even the medical records of the immediate family members, on the blockchain, you will have first-hand information about the current physical condition, disease history and family history of the insured, effectively eliminating the insurance with diseases
at present, Tongxin society is the first network mutual aid platform with blockchain technology as the core in China, so blockchain technology is also one of the effective technical means for in-process supervision.

the first is to get through the data between different companies and refer to each other, so as to discover the information of repeated insurance and historical claims in time, and discover high-risk users in time. Taking the 40 million accident insurance fraud in March this year as an example, Zhou of Yangzhou took out insurance in more than ten life insurance companies, which was not found out until the manual underwriting. If every insurance information is recorded in the blockchain, it can be found and timely measures can be taken
secondly, introcing data from different instries into the blockchain can improve the accuracy and efficiency of underwriting and claims verification. For example, if you can query all the medical records of the insured, even the medical records of the immediate family members, on the blockchain, you will have first-hand information about the current physical condition, disease history and family history of the insured, effectively eliminating the insurance with diseases
at present, Tongxin society is the first network mutual aid platform with blockchain technology as the core in China, so blockchain technology is also one of the effective technical means for in-process supervision.
