1. Government management
some countries have shown great interest in the blockchain technology of decentralized data management framework to store public data. For example, essentia is developing an e-government project with the Central Union of agricultural procers and forest owners in Finland, The project will apply blockchain technology to enable urban and rural residents in Finland to query various records, fully meet the needs of residents and employers, and improve the employment rate. In addition, the use of this technology can also improve the efficiency of government operation, so that residents can easily query ecation, public records, voting and other information
waste recycling
for example, an intelligent waste management system in China adopts the RFID technology of waltonchain company. Using this blockchain application of waltonchain, it can effectively monitor the waste level, so as to improve the management and operation efficiency and resource optimization
identity recognition
chug, a Swiss city known as "encryption Valley", has developed an identity authentication system with its partner uport by using blockchain technology, through which citizens can participate in online voting and proof of residence
border control
essentia has been in contact with the Dutch government, hoping to use its blockchain technology to establish a set of border inspection system for the Dutch government to check passengers between Amsterdam and London. At present, passengers of Eurostar high-speed rail between the two countries need to undergo border control checks at multiple locations. Essentia is working on a blockchain based solution that will securely store passenger data so that inspection records from the Netherlands can also be reviewed by UK Border agencies. Blockchain technology will ensure that the data has not been tampered with and is verifiable and accurate
health care
as we all know, medical records are very scattered and prone to errors. Inconsistent data processing process will make hospitals and clinics often forced to deal with some incorrect or incomplete patient records. For example, Medrec, a blockchain electronic medical record system developed by MIT, uses blockchain technology to promote data sharing. At the same time, it can also provide authentication and confidentiality services
enterprise management
as enterprise customers of Microsoft azure applications, they can make use of blockchain as a service (baas), which will enable enterprises to access smart contracts and blockchain applications in a secure hosting environment. According to media reports, Google is also developing a proprietary blockchain project to support its cloud based business. And alpha, Google's parent company, is developing a distributed accounting project that third parties will be able to use to store data related to Google's cloud services
medical data
medical centers that digitize patient records do not store data among multiple devices. They usually store data on centralized servers, which has become the main target of hackers. The wannacry attack on NHS hospital in the UK proves this. But in addition, even if the security risk is ignored, there is still the problem of fragmentation. At present, there are more than 50 different electronic medical record systems (EHR) operating in hospitals in different cities around the world, and there are usually dozens of different medical application systems in the same city. These independent systems can't perform interoperation, and the data of patients in each hospital can only be distributed in different data storage centers
in the case of patients' life and death, the lack of reliable medical data contrast and slow operation efficiency will be fatal. Essentia's application framework solves all these problems by using blockchain based system, which will store all clinical data of patients, and can access these data immediately regardless of geographical boundaries. In this system, the patient's medical record privacy can also be protected, and only the authorized medical personnel can access it in a specific period of time
Music Proction
one of the main advantages of blockchain technology is that it eliminates unnecessary middlemen or middlemen. The music instry is a typical example. In this instry, if artists are inefficient, they will get very low remuneration. At this time, a number of blockchain based projects have emerged to seek a fairer trading and business environment for music creators, such as artbit, a former gunshot rose drummer Matt Soren as director
carbon compensation
as a highly instrialized country, China's environmental change is huge. In March 2017, IBM and energy blockchain labs jointly launched the hyperledger fabric blockchain project to discover China's carbon assets, which not only creates a measurable and auditable system for tracking carbon emissions, but also provides a tradable market for companies seeking to offset energy consumption and stimulate green instrial practice
supply chain management
supply chain management is considered to be one of the better cases of applying blockchain, because it is very suitable for the express delivery of such goods from delivery to receipt or the whole process from manufacturer to store. IBM and Wal Mart have jointly launched a blockchain food safety alliance in China. The project is also jointly operated with Jingdong company, aiming to improve food delivery tracking and safety assurance, so as to make it easier to trace food safety issues
facts have proved that China is a mature experimental base for blockchain projects, and it is also the location of the world's first blockchain for agricultural procts (5.180, - 0.25, - 4.60%). Louis Dreyfus Co, a world-famous food trader, has established a blockchain technology project in cooperation with Dutch and French banks. Using this project technology, the transaction settlement is faster than traditional methods in the process of selling soybeans to China
diamond instry
De Beers Group, the world's most famous diamond company, has its own blockchain company and has started operation. Its purpose is to "establish a digital record for every diamond registered on the platform". Considering the origin of diamonds, the ethical standards of origin, and the risk of diamond quality, blockchain technology is a good choice, because every record of it is indelible, and it will ensure that the electronic data of each diamond is as permanent as itself
real estate transactions
currently, Ukraine is the first country to use blockchain technology to promote property transactions. Michael Arlington, the founder of techcrunch, a famous technology website and cryptocurrency player, remotely purchased and resold a real estate in Kiev through the smart contract of Ethereum blockchain. This transaction was completed by propy, a start-up company specializing in blockchain real estate transactions
fisheries
blockchain technology is now being used to support the development of sustainable fisheries. Illegal fishing is a common problem in this instry. The distributed ledger technology of blockchain provides a proof of the capture source, processing and sale mode. This "net to table" supply chain allows inspectors to determine whether the fish caught came from a human rights violation area or from a country affected by economic sanctions
art paintings
similar to diamond trading, the art instry relies on the provenance and authenticity of art works. Although the blockchain cannot identify whether a painting is an original or a fake, it can be used to prove the identity of the previous owner of the painting. In addition, blockchain technology is now also used as a means to obtain works of art. It can make tangible goods easily traded and exchanged anywhere in the world without physical transfer from a secure storage place
public facilities
in Freemantle, Australia, a project dedicated to distributed energy and water system management is using blockchain technology, and solar panels (3.340, - 0.06, - 1.76%) are being used in sunny areas to obtain electricity, which is then used to heat water and provide electricity, All these energy conversion and use information will be recorded in the blockchain data
in Chile, the National Energy Commission has started to use the blockchain technology as the verification of the country's energy use data, and some sensitive data will be stored in the blockchain. The application of this technology can be regarded as a means for the modernization and safe operation of power infrastructure in this South American country
LGBT rights
blockchain can help build a "pink economy" and help LGBT communities fight for their own rights without revealing people's identities. This is an extremely important issue, because crimes of discrimination against homosexual groups often occur, especially in countries notorious for human rights violations, Homosexuality is illegal, or at least not allowed
catastrophe bonds
catastrophe bonds may be the only hope for victims of earthquakes, tsunamis and other natural disasters. Blockchain allows fast and transparent reconciliation between the parties, and can ensure that the system can continue to operate normally even under unmanned operation. Now, blockchain has been successfully used in the settlement mechanism of catastrophe bonds
tourism
local institutions in Hawaii are studying how to use blockchain technology to improve the economy, such as opening bitcoin and other monetary payment means to facilitate tourists' transaction of local goods and services. In this way, the Hawaiian government hopes to attract tourists, especially those from Asia, to spend more money in the local area and improve the economic development of Hawaii
homeland security
in 2016, the US Department of Homeland Security (DHS) announced a project that will use blockchain technology as a means of secure storage and capture of data transmission. DHS uses Factom's blockchain technology to encrypt and store data captured by security cameras and other sensors. The application of this blockchain technology will greatly rece the risk of data leakage. At present, the project is still in progress
maritime transportation
it is self-evident that blockchain is used to record ship transportation data. At present, some local shipping projects have adopted distributed ledger technology. In the maritime logistics instry, blockchain technology can make the inevitable cumbersome management proceres in international trade more transparent and orderly. Maersk, one of the world's largest shippers, is a pioneer in the use of blockchain. Today, Yixing international shipping company Zim has also made follow-up use of blockchain technology.

2. Blockchain is a public accounting mechanism
blockchain is decentralized, tamper resistant and anonymous
the blockchain system is actually a distributed system
bitcoin system is the earliest blockchain system and the simplest blockchain system
the whole bitcoin system is actually a distributed ledger. This ledger is backed up on each node. When a transaction occurs, it will be broadcast to the network. The miner node (the node solving the problem) in the network will mine (the node solving the problem) to record the transaction. The recorded block will be broadcast to the network, and other nodes will verify and synchronize to their own node's account book.

extended data:
blockchain is far more than a technology, which involves the spirit of "multi-party cooperation". In modern society, a lot of things must rely on everyone's cooperation to achieve 1 + 1 & gt; But we should try our best to avoid the problem of "information asymmetry" in cooperation
therefore, members of the alliance should keep accounts and share data together, and make everything public to eliminate "information asymmetry", so as to protect everyone's interests and make the business environment develop healthily. Honest work will get e benefits, if cheating will naturally be known to all. Technology is the foundation to help achieve this pattern. This is the more important "blockchain thinking"
4. Blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry
taking the tourism instry as an example, blockchain applications mainly focus on tourism travel, tourism community reviews, digital identity management, credit consumption management, tracking pilot's professional certificate and qualification, loyalty plan of hotels and airlines, reservation management and consumption points management. In addition, blockchain also has applications in finance, games, entertainment and other fields.

6. Principle of blockchain: decentralized distributed accounting system
the core of blockchain technology is that all participating nodes jointly maintain the transaction and database, which makes the transaction based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party< br />?
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the blocks of the transactions that have been reached are connected together to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash formed by the previous block, and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All miners compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction
1.1 what is a blockchain
blockchain is a technical solution to collectively maintain a reliable database through centralization and de trust in the past. This technical solution mainly allows any number of nodes in the participating system to generate a series of data blocks by using cryptographic methods. Each data block contains all the information exchange data of the system in a certain period of time, and generates a data fingerprint to verify the validity of its information and link to the next database block< br />?
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems, that is, a big ledger. So it's very important who keeps this account book. At present, whose system is responsible for bookkeeping, the account book of each bank is the account book of each bank, and the account book of each bank is the account book of Ali. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there are new transaction data changes in a certain period of time, everyone in the system can make bookkeeping. The system will judge the fastest and best bookkeeper in this period, write the recorded content into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. As a result, the data becomes very secure. Tamperers need to modify more than half of the system node data at the same time to truly tamper with the data. The cost of such tampering is so high that it is almost impossible. For example, bitcoin has been running for more than seven years, and countless hackers around the world have tried to attack bitcoin, but so far there have been no trading errors. It can be considered that bitcoin blockchain has been proved to be a safe and reliable system< br />?
1.2 why is there blockchain innovation
human beings need to communicate in the process of activities, and communication is based on information. In the past, information circulation was not convenient enough to meet the information needs of market participants, so the intermediary and center were born. This centralized system has the problems of high cost, low efficiency, scattered value, "information island" and unsafe data storage. However, e to technical and environmental factors, this system still continues to operate for many years until the emergence of the Internet. The starting point of the first generation Internet is TCP / IP protocol, which is to implement the open code of peer-to-peer transmission of information in a unified format of all nodes on the network, and to program, protocol and execute the basic values of freedom and equality needed by the global unified market. Internet eliminates the middle chain of low value and high cost, and realizes the low cost and high efficiency of global information transmission by decentralization< br />?< However, the first generation Internet did not solve the credit problem of information. The activities that can be decentralized on the Internet must be those that do not need credit endorsement, and those that need credit guarantee must be those that are centralized and participated by third-party intermediaries. As a result, Internet technology, which is unable to establish global credit, has encountered great obstacles in its progress - people can not participate in any value exchange activities on the Internet in a decentralized way. In order to realize value exchange, people still need the third-party intermediary (such as bank, clearing, exchange) based on credit. There are still some problems in the global centralized credit system, such as high operating cost, low efficiency and vulnerability to attack. For example, the legal currencies of different countries have different credit values and different clearing systems, which increase the cost of Global trade< br />?
therefore, what the second generation Internet must break through is: how to decentralize the establishment of global credit? So that the value transfer is also low-cost and efficient. We need to create a kind of technology in the Internet, which can also engage in value exchange activities on the premise that people can't trust each other, so as to achieve real decentralization and go to the third-party intermediary, and realize the transformation from information internet to value Internet
1.3 application of blockchain
Bubi blockchain has been applied to equity, supply chain, points and other fields, and is carrying out experiments and application tests with exchanges and banks
as an integral application on Bubi blockchain, Shubei Hebao has been launched recently, which is a good demonstration for the landing application of blockchain technology in various instries
1.4 why the financial instry needs blockchain
trust is the foundation of the financial instry. In order to maintain trust, the development of the financial instry has spawned a large number of high-cost, low-efficiency, single point of failure intermediaries, including trusteeship, third-party payment, notaries, banks, exchanges and so on. Blockchain technology uses new encryption authentication technology and decentralized consensus mechanism to maintain a complete, distributed and tamperable account book, so that participants can ensure the security of funds and information through a unified account book system without mutual recognition and trust. This is of great significance to finance. Therefore, global financial giants are exploring blockchain applications one after another. On the one hand, this is to prevent the risk of being subverted; on the other hand, it is also "for our own use" to improve efficiency and rece costs, so as to consolidate, optimize and expand the existing power< br />?
first, blockchain can rece trust risk. Blockchain technology has the characteristics of open source and transparency. The participants of the system can know the operation rules of the system, verify the authenticity and integrity of the account book content and account book construction history, and ensure that the transaction history is reliable and has not been tampered with, which is equivalent to improving the accountability of the system and recing the trust risk of the system. For example, blockchain can avoid the current Internet Financial P2P running, fraud and other events< br />?
secondly, blockchain can improve the efficiency of payment, transaction and settlement. On the blockchain, the process of transaction confirmation is the process of clearing, settlement and auditing. Blockchain uses distributed accounting, all transactions are displayed in real time on a spreadsheet similar to global sharing, real-time clearing, and efficiency is greatly improved. For example, the U.S. securities settlement system is t + 3, but the blockchain can improve the efficiency to the minute level, which can rece the settlement risk by 99%, thus effectively recing the cost of capital and systemic risk< br />?
thirdly, blockchain can rece operating costs. Financial business systems and back office work are often faced with long processes and multiple links. Nowadays, no matter visa, master or all of them operate in a centralized way, money transfer has to go through a third party, which makes the cost of cross-border transaction, currency exchange rate, internal accounting and time cost too high, and brings risks to capital. Blockchain can simplify and automate the lengthy financial service process, rece the interaction between foreground and background, and save a lot of human and material resources, which is of great significance to optimize the financial business process and improve the financial competitiveness. The Bank of Spain believes that by 2022, blockchain technology will help the financial instry rece its bookkeeping costs by $20 billion< br />?
fourthly, blockchain can effectively prevent failures and attacks. The traditional financial model takes the exchange or bank as the center. Once the center fails or is attacked, the whole network may be paralyzed and the transaction will be suspended. The blockchain is supported by many distributed nodes and computer servers on the point-to-point network. The problems of any part will not affect the overall operation, and each node keeps a of the blockchain data. Therefore, the built-in business continuity of blockchain has high reliability and fault tolerance< br />?
fifthly, blockchain can improve the level of automation. Since all files or assets can be represented in the form of codes or ledgers, smart contracts and automatic transactions can be realized on the blockchain by setting the data processing program on the blockchain. For example, a smart contract can write a set of financial terms into the agreement to ensure the automatic execution and default payment of the contract< br />?
sixth, blockchain can meet regulatory and audit requirements. The records stored on the blockchain are transparent, traceable and unchangeable. Any record, once written to the blockchain, is permanent and cannot be tampered with. Any transaction between two parties can be tracked and inquired< br />?
in addition to the above positive effects on existing systems and business models, blockchain can also drive the birth of new business models. On the one hand, the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode. On the other hand, blockchain greatly encourages the innovation and cooperation of the whole society through the opening and cooperation of source code. Of course, there will be a lot of problems and challenges in the application of blockchain in finance. This paper also thinks about the specific application
the working principle of blockchain technology is not difficult to understand. If we focus on the application research of specific blockchain technology, we can find that the working principle of this blockchain technology is ubiquitous.
the core of blockchain technology is that all participating nodes jointly maintain the transaction and database, which makes the transaction based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party< br />?
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the blocks of the transactions that have been reached are connected together to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash formed by the previous block, and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All miners compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction
1.1 what is a blockchain
blockchain is a technical solution to collectively maintain a reliable database through centralization and de trust in the past. This technical solution mainly allows any number of nodes in the participating system to generate a series of data blocks by using cryptographic methods. Each data block contains all the information exchange data of the system in a certain period of time, and generates a data fingerprint to verify the validity of its information and link to the next database block< br />?
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems, that is, a big ledger. So it's very important who keeps this account book. At present, whose system is responsible for bookkeeping, the account book of each bank is the account book of each bank, and the account book of each bank is the account book of Ali. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there are new transaction data changes in a certain period of time, everyone in the system can make bookkeeping. The system will judge the fastest and best bookkeeper in this period, write the recorded content into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. As a result, the data becomes very secure. Tamperers need to modify more than half of the system node data at the same time to truly tamper with the data. The cost of such tampering is so high that it is almost impossible. For example, bitcoin has been running for more than seven years, and countless hackers around the world have tried to attack bitcoin, but so far there have been no trading errors. It can be considered that bitcoin blockchain has been proved to be a safe and reliable system< br />?
1.2 why is there blockchain innovation
human beings need to communicate in the process of activities, and communication is based on information. In the past, information circulation was not convenient enough to meet the information needs of market participants, so the intermediary and center were born. This centralized system has the problems of high cost, low efficiency, scattered value, "information island" and unsafe data storage. However, e to technical and environmental factors, this system still continues to operate for many years until the emergence of the Internet. The starting point of the first generation Internet is TCP / IP protocol, which is to implement the open code of peer-to-peer transmission of information in a unified format of all nodes on the network, and to program, protocol and execute the basic values of freedom and equality needed by the global unified market. Internet eliminates the middle chain of low value and high cost, and realizes the low cost and high efficiency of global information transmission by decentralization< br />?< However, the first generation Internet did not solve the credit problem of information. The activities that can be decentralized on the Internet must be those that do not need credit endorsement, and those that need credit guarantee must be those that are centralized and participated by third-party intermediaries. As a result, Internet technology, which is unable to establish global credit, has encountered great obstacles in its progress - people can not participate in any value exchange activities on the Internet in a decentralized way. In order to realize value exchange, people still need the third-party intermediary (such as bank, clearing, exchange) based on credit. There are still some problems in the global centralized credit system, such as high operating cost, low efficiency and vulnerability to attack. For example, the legal currencies of different countries have different credit values and different clearing systems, which increase the cost of Global trade< br />?
therefore, what the second generation Internet must break through is: how to decentralize the establishment of global credit? So that the value transfer is also low-cost and efficient. We need to create a kind of technology in the Internet, which can also engage in value exchange activities on the premise that people can't trust each other, so as to achieve real decentralization and go to the third-party intermediary, and realize the transformation from information internet to value Internet
1.3 application of blockchain
Bubi blockchain has been applied to equity, supply chain, points and other fields, and is carrying out experiments and application tests with exchanges and banks
as an integral application on Bubi blockchain, Shubei Hebao has been launched recently, which is a good demonstration for the landing application of blockchain technology in various instries
1.4 why the financial instry needs blockchain
trust is the foundation of the financial instry. In order to maintain trust, the development of the financial instry has spawned a large number of high-cost, low-efficiency, single point of failure intermediaries, including trusteeship, third-party payment, notaries, banks, exchanges and so on. Blockchain technology uses new encryption authentication technology and decentralized consensus mechanism to maintain a complete, distributed and tamperable account book, so that participants can ensure the security of funds and information through a unified account book system without mutual recognition and trust. This is of great significance to finance. Therefore, global financial giants are exploring blockchain applications one after another. On the one hand, this is to prevent the risk of being subverted; on the other hand, it is also "for our own use" to improve efficiency and rece costs, so as to consolidate, optimize and expand the existing power< br />?
first, blockchain can rece trust risk. Blockchain technology has the characteristics of open source and transparency. The participants of the system can know the operation rules of the system, verify the authenticity and integrity of the account book content and account book construction history, and ensure that the transaction history is reliable and has not been tampered with, which is equivalent to improving the accountability of the system and recing the trust risk of the system. For example, blockchain can avoid the current Internet Financial P2P running, fraud and other events< br />?
secondly, blockchain can improve the efficiency of payment, transaction and settlement. On the blockchain, the process of transaction confirmation is the process of clearing, settlement and auditing. Blockchain uses distributed accounting, all transactions are displayed in real time on a spreadsheet similar to global sharing, real-time clearing, and efficiency is greatly improved. For example, the U.S. securities settlement system is t + 3, but the blockchain can improve the efficiency to the minute level, which can rece the settlement risk by 99%, thus effectively recing the cost of capital and systemic risk< br />?
thirdly, blockchain can rece operating costs. Financial business systems and back office work are often faced with long processes and multiple links. Nowadays, no matter visa, master or all of them operate in a centralized way, money transfer has to go through a third party, which makes the cost of cross-border transaction, currency exchange rate, internal accounting and time cost too high, and brings risks to capital. Blockchain can simplify and automate the lengthy financial service process, rece the interaction between foreground and background, and save a lot of human and material resources, which is of great significance to optimize the financial business process and improve the financial competitiveness. The Bank of Spain believes that by 2022, blockchain technology will help the financial instry rece its bookkeeping costs by $20 billion< br />?
fourthly, blockchain can effectively prevent failures and attacks. The traditional financial model takes the exchange or bank as the center. Once the center fails or is attacked, the whole network may be paralyzed and the transaction will be suspended. The blockchain is supported by many distributed nodes and computer servers on the point-to-point network. The problems of any part will not affect the overall operation, and each node keeps a of the blockchain data. Therefore, the built-in business continuity of blockchain has high reliability and fault tolerance< br />?
fifthly, blockchain can improve the level of automation. Since all files or assets can be represented in the form of codes or ledgers, smart contracts and automatic transactions can be realized on the blockchain by setting the data processing program on the blockchain. For example, a smart contract can write a set of financial terms into the agreement to ensure the automatic execution and default payment of the contract< br />?
sixth, blockchain can meet regulatory and audit requirements. The records stored on the blockchain are transparent, traceable and unchangeable. Any record, once written to the blockchain, is permanent and cannot be tampered with. Any transaction between two parties can be tracked and inquired< br />?
in addition to the above positive effects on existing systems and business models, blockchain can also drive the birth of new business models. On the one hand, the characteristics of blockchain technology enable it to achieve some business models that are difficult to achieve in the centralized mode. On the other hand, blockchain greatly encourages the innovation and cooperation of the whole society through the opening and cooperation of source code. Of course, there will be a lot of problems and challenges in the application of blockchain in finance. This paper also thinks about the specific application
the working principle of blockchain technology is not difficult to understand. If we focus on the application research of specific blockchain technology, we can find that the working principle of this blockchain technology is ubiquitous.
7. With the innovation and upgrading of blockchain, the deep integration of blockchain technology with more and more real instries plays an increasingly key role in promoting cross regional collaborative development of manufacturing instry, instrial interconnection, intelligent manufacturing, data sharing, and financial empowerment of real economy
the blockchain itself also needs to consider password security. Because blockchain is a kind of additional account book that can encode the effective transactions in the system by using cryptography technology, we must strengthen the security of the password itself. At the same time, the security of blockchain is the same as other important information systems, so the system security must be strengthened
from the perspective of talent supply side, the growth rate of blockchain talents can not meet the market demand. According to the data of LinkedIn in February 2018, the global demand for blockchain talents began to grow in 2015 and experienced explosive growth from 2016 to 2017. However, at present, its proportion in the total demand of the global talent market is still very low. In recent years, the instry with the fastest growing demand for blockchain talents is the computer software instry, followed by the financial services and insurance instry. From 2015 to 2017, the number of talents with blockchain related skills on LinkedIn's archives has increased nearly 19 times, but the total number of talents is still small, which is only about 2% of the global AI talents on LinkedIn's platform
the ecology of blockchain instry chain is graally forming. In 2018, the whole instry status, including hardware and infrastructure, platform and infrastructure, general technology layer and peripheral service layer, has made relevant progress. It has become a subversive and strategic key supporting technology, and also an important technology to promote the integration of digital economy and real economy
to enable the deep integration of digital economy and real economy, blockchain should further increase investment, strengthen basic research, enhance the original innovation ability, strive to occupy the commanding height of innovation and obtain new instrial advantages. In particular, the implementation of blockchain in China faces not only technical problems, but also challenges of market integration, talent training and legal system. At present, the entity enterprises' cognition of blockchain is relatively insufficient, and their awareness of change is not strong, which also restricts the development of blockchain technology in the field of manufacturing
