Application prospect of blockchain in crowdfunding industry
blockchain classification:
1 private chain
refers to the blockchain with certain centralized control. Only the general ledger technology of blockchain is used for bookkeeping. It can be a company or an indivial who enjoys the exclusive write permission of the blockchain. This blockchain is not very different from other distributed storage schemes. The participating nodes are only users themselves, and the access and use of data have strict authority management. Due to the existence of centralized control, alliance chain can also be considered as a private chain
features: because the user has the final say, the data inside can not be changed, and there is not much protection for the third party. Generally used for internal audit. The vice president of fire coin technology believes: there are indeed a large number of scenarios in the private chain that can meet the needs of the real world. Limited decentralization makes it easier to reach a consensus, which can make the transaction faster and more efficient, and can provide more controlled functions. Decentralization is the core value of blockchain technology. If the private chain can not make full use of the decentralized trust base constructed by the public chain in practice, its development space will be limited
2public chain
public blockchain is the earliest blockchain and the most widely used one at present. It refers to a completely decentralized blockchain like bitcoin blockchain, which is not controlled by any organization. Any indivial or group in the world can send a transaction, and the transaction can be effectively confirmed by the blockchain, and anyone can participate in the consensus process. Participants in the consensus process maintain database security through cryptography and built-in economic incentives
features: completely open, uncontrolled, rely on encryption technology to ensure security
3 alliance chain
multiple preselected nodes are designated as bookkeepers within a certain group. The generation of each block is jointly determined by all preselected nodes. Other access nodes can participate in the transaction, but not the bookkeeping process (in essence, it's still managed bookkeeping, but it's just distributed bookkeeping. How many preselected nodes are there, How to decide the bookkeeper of each block becomes the main risk point of the blockchain). Anyone else can make limited query through the open API of the blockchain
the nodes participating in the blockchain are selected in advance, and the nodes are likely to have good network connections. Other consensus algorithms without workload proof can be used on such a blockchain. For example, a blockchain has been established among 100 financial institutions, and more than 67 institutions must agree to reach a consensus
Prospect:
the development of blockchain technology has also brought changes in the operation concepts of various instries. New technologies and new concepts have promoted the new development of various instries. This driving force has a huge impact on society and the promotion of economic activities. Many new instrial phenomena will occur one after another, and the public will wait and see, It is expected that this new technology will be used by all instries and benefit all instries better
Five aspects of blockchain instry growth potential promote the healthy development of Technology Virtual reality and other technologies are another emerging technology that will have a significant impact on the future, which is expected to promote human beings from the era of information internet to the era of value Internet
some countries and regions in the United States, Japan and the European Union have promoted the development of blockchain as an important national development strategy, and vigorously promoted the development and application of blockchain technology. China also attaches great importance to the technological innovation and instrial development of blockchain.

Support eligible blockchain enterprises to enjoy the preferential tax policies of the state to support the development of software instry and small and medium-sized enterprises
the instrial scale is small, but the growth potential is huge
the blockchain economy is on the eve of the outbreak period. The financial instry is relatively widely used, and the application of other instries has also entered the stage of exploration and development. It is estimated that from 2017 to 2022, the direct market value of blockchain will increase from US $410 million to US $7.68 billion, with a compound annual growth rate of 79.6%. It is estimated that all kinds of extended business based on blockchain will reach US $100 billion in 2020
instry application areas continue to expand
the financial instry takes the lead in the application of blockchain technology, and many financial applications have been implemented; Medical instry is an important area of blockchain application, which can better protect privacy, improve service quality and management efficiency; The demand of social authentication for blockchain is rising rapidly to solve the proof problem caused by information asymmetry; The application of blockchain technology in communication, supply chain and other fields is expanding rapidly
the blockchain instry is in the stage of rapid development
China's blockchain instry is in the stage of rapid development. According to the data of the "in-depth analysis report on business model innovation and investment opportunities of blockchain instry" released by foresight Instry Research Institute, by the end of March 2018, the number of blockchain companies with blockchain business as the main business in China has reached 456, from upstream hardware manufacturing, platform services, security services to downstream instrial technology application services, To ensure the development of the instry investment and financing, media, talent services, companies in various fields have been basically complete
according to the classification of application scenarios of top 20 enterprises in the ranking list, in addition to 13 enterprises focusing on the infrastructure and platform construction of blockchain such as underlying platform and blockchain hardware, the application scenarios of blockchain have graally enriched. According to the distribution of instry segments, there are 7 instry application companies, mainly Internet companies (Alibaba, Jingdong, Tencent) used in public welfare and commodity traceability, and innovative financial technology applications evolved by financial enterprises (Ping An, CMB, BOC), such as supply chain finance, bills and transaction clearing
as the blockchain can realize the non tampering of information, the possibility of data falsification is eliminated from the root, especially in the financial instry, which has high requirements for real data, it will embrace the blockchain more actively

Second, blockchain has become a new hot spot for innovation and entrepreneurship, and technology integration will expand new application space
3. Blockchain will be widely implemented in the real economy in the next three years and become an important support for the construction of Digital China
fourthly, blockchain creates a new platform economy and opens a new era of sharing economy
fifthly, blockchain accelerates the process of "credible digitization" and drives finance to "move from virtual to real" to serve the real economy< Sixth, the blockchain supervision and standard system will be further improved, and the instrial development foundation will continue to be consolidated
in addition, as an emerging technology, there are still many technical difficulties in the application of blockchain in the actual proction environment of the financial instry, such as throughput, scalability, consensus mechanism, privacy and security, manageability, etc
technological innovation such as blockchain is of great significance to the financial instry, which is expected to accelerate the process of "credible digitization" and continuously drive the financial instry to "move from virtual to real".
From District TV network Share: in 2018, blocklink bar AI has become the most popular technical term, and more and more technology companies have announced to enter the blockchain market. In the Internet, Xunlei, Renren, Fengfeng, Tianya and other companies have blockchain related actions. These companies share the same fate. They have all experienced prosperity, but after the impact of Internet entrepreneurship tide, they began to go downhill. Then they rubbed against the hot spots of blockchain and began to try to counter attack
Global blockchain instry investment is hot
according to the data of the "in-depth analysis report on business model innovation and investment opportunities of blockchain instry" released by prospective instry research institute, as of the end of April 2017, there were 455 blockchain companies in the world, with a total financing amount of US $1.947 billion. Among them, the total investment and financing of us blockchain related companies reached US $1.252 billion, accounting for 64.3% of the global market; The total financing amount of China's blockchain emerging enterprises is about US $114 million, accounting for 5.86%, ranking second in the world after the United States, and growing rapidly
at present, the overall survival status of blockchain is good, with a survival rate of 87.25%. Among all the invested companies, 47 have been closed, accounting for about 10.51%, and the other 10 have been acquired. Due to the change of competition pattern in bitcoin market, some companies have been forced to shut down. Meanwhile, some coin circle companies are graally transforming to chain circle companies.
exploration at the national level has also begun. On March 23, the information technology and Software Services Department of the Ministry of instry and information technology announced that it will study and explore the application of blockchain in the instrial field. Previously, the Ministry of instry and information technology said that it was preparing to establish a National Technical Committee for standardization of blockchain and distributed accounting technology to explore the formation of a complete blockchain standard system to better serve the development of blockchain technology instry
The application prospects of blockchain are mainly in the fields of finance, Internet of things and logistics, public services, digital rights and insurance
1. Blockchain has great potential applications in international exchange, letter of credit, equity registration, stock exchange and other financial fields. The application of blockchain technology in the financial instry can eliminate the third-party intermediary link and realize the point-to-point direct docking
2. Blockchain can also be naturally combined in the field of Internet of things and logistics, which is considered as a promising application direction of blockchain. The establishment of credit resources in the blockchain can double improve the security of transactions and improve the convenience of Internet of things transactions. It can save time and cost for the application of intelligent logistics mode
3. Blockchain is closely related to people's proction and life in public management, energy, transportation and other fields. The decentralized and fully distributed DNS service provided by blockchain can realize the query and resolution of domain name through the point-to-point data transmission service between nodes in the network
4. Through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership. After the works are confirmed on the blockchain, the subsequent transactions will be recorded in real time to realize the full life cycle management of digital rights, and can also be used as a technical guarantee in judicial evidence collection
5. In terms of insurance claims, insurance institutions are responsible for fund collection, investment and claims settlement, and often have higher management and operation costs. Through the application of smart contract, there is no need for the applicant to apply or the insurance company to approve. As long as the claim conditions are triggered, the automatic claim settlement of the policy can be realized
extended data:
the core technology of blockchain
1. Consensus mechanism, through the voting of special nodes, completes the verification and confirmation of transactions in a very short time; For a transaction, if several nodes with unrelated interests can reach a consensus, it can be considered that the whole network can also reach a consensus. The goal of blockchain consensus mechanism is to make all honest nodes keep consistent blockchain views
2. Asymmetric encryption requires two keys for encryption and decryption, which are public key and private key. The public key corresponds to the private key. The public key is used in the process of data encryption, and only the corresponding private key can be used to decrypt; On the contrary, the private key is used to encrypt the data, and only the corresponding public key can be used to decrypt the data
a day ago, Sheng Songcheng, counselor of the people's Bank of China and executive vice president of China Europe Lujiazui Institute of international finance, also said that the future of blockchain is to serve the real economy“ If blockchain and virtual currency are combined, and blockchain is mainly focused on virtual currency, I don't think blockchain will have a future. " Sheng Songcheng said
Li Lihui, head of the blockchain research working group of China mutual Finance Association and former president of Bank of China, believes that the future development direction of blockchain is large-scale application. In his view, how to achieve large-scale application depends on four factors: efficiency, cost, reliability and safety, and system
Zhu Min, former vice president of Bank of China, central bank and IMF, and now president of National Institute of finance of Tsinghua University, said at the Boao Forum: "when talking about blockchain, we should first separate blockchain from bitcoin, which is not a concept. As a technology, blockchain is revolutionary and unlimited in the future. Blockchain technology will have great application prospects in the future, and the future is very good. "
"the combination of blockchain and virtual currency has no future"
as early as 2014, Sheng Songcheng published an article in an authoritative journal, explaining that virtual currency is not currency in essence from the origin and essence of currency
in his view, if virtual currency overflows, monetary policy can not be implemented, and monetary policy is one of the main means of macroeconomic regulation and control in the world
according to him, when virtual currency first came out, the attitude of central banks was not unified“ But up to now, we have basically unified our views, at least we do not recognize it as currency, because it will hinder the implementation of the whole monetary policy. " Sheng Songcheng said< As early as November 20, 2013, Yi Gang, who was also vice president of the people's Bank of China, first talked about bitcoin at a forum. At that time, he said that from the perspective of the central bank, it was impossible to recognize the legitimacy of bitcoin in the near future. However, he also believes that bitcoin trading, as a kind of trading behavior on the Internet, ordinary people have the freedom to participate
at that time, Yi Gang's statement was interpreted as good news by some bitcoin investors. They believed that although the regulatory authorities did not recognize the legitimacy of bitcoin, they did not characterize it as illegal and would not directly interfere in the trading of bitcoin. But unexpectedly, the price of bitcoin fell to 4150 yuan the next day.
the favorable development prospect of blockchain will drive the overall rise of a shares and become the focus of investment institutions. The rapid development of blockchain will bring new changes to the global personal payment mode, Global trade settlement system, global currency issuance mechanism, and improve the operation efficiency of instrial chain
I. The personal payment method has been subvertedthe future development prospect of blockchain will be connected with global commercial banks and Payment institutions to solve the multi-party communication in cross-border remittance, participate in the transmission of documents and newspapers, and realize the cross regional and cross time synchronous coordination and processing of all parties' information, which can greatly improve our original serial processing among institutions, Efficient processing of global personal payments{ RRRRR}
