1. blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is 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
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected 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 nodes 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.

2. The definition of Chongqing jinwowo analysis blockchain technology is as follows:
1. Blockchain is a distributed database (system) placed in a non secure environment
2. The blockchain uses cryptography to ensure that the existing data cannot be tampered with
3, the blockchain uses consensus algorithm to reach consensus on new data
the system with the above three properties is blockchain.

3. A brief review of the origin of blockchain
blockchain is the underlying system of distributed ledger in bitcoin. Bitcoin ledgers are built in a distributed and spontaneous way. Anyone can generate new currency blocks by performing specific cryptographic calculations, so as to obtain a digital "currency" that can be used for transactions. Bitcoin's impact on the world monetary system can be said to be subversive, which is also an important reason why it has attracted a lot of people's strong attention since it came out. After that, there were dozens of similar electronic currencies such as
"lightcoin". The abstract extraction of distributed digital currency technology from bitcoin forms a "blockchain" technology, which can be used in more fields
the basic idea of blockchain is to establish a network-based public ledger (data block), each block contains the information of a network transaction. All the participating users in the network work together to keep accounts and check accounts. All the data are open and transparent, and can be used to verify the effectiveness of the information. In this way, the authenticity and non tamperability of information can be guaranteed at the technical level without the central server as the trust intermediary
the significance of blockchain lies in "decentralization", which can fundamentally solve the fraud and rent-seeking phenomenon in value exchange and transfer by building a more reliable network system. With the popularization of blockchain technology, the digital economy will be more authentic, and the economic society will become more fair and transparent
not only digital currency, but also blockchain technology is infiltrating into more innovative fields.
virtual digital currency such as bitcoin is just an application scenario of blockchain technology. Theoretically speaking, based on the characteristics of blockchain technology, human beings can create a very rich form of services and procts, such as finance, government, enterprises, etc There are a large number of scenarios suitable for blockchain technology in cross instry and other fields, with broad prospects. At present, many countries around the world have started the research of blockchain technology, and a series of instry organizations and alliances have been established. However, as blockchain technology is a brand-new technology, which subverts the traditional centralized mode, major institutions are still in the research stage, with only a small number of actual projects landing, and the great development of the instry has just begun
now, blockchain economy is on the eve of outbreak. The exploration of financial instry is ahead of others, while the application of other instries is developing rapidly. The obvious advantage of blockchain instry application is to optimize business process, rece operation cost and improve collaborative efficiency. This advantage has been graally reflected in financial services, Internet of things, public services, social welfare and supply chain management
as the backbone of emerging technologies, blockchain is not only used in the field of virtual currency, but also in other fields such as finance, medical care, intellectual property certification, etc. a large number of excellent enterprises have emerged in China to explore or enter the blockchain instry. According to the in-depth analysis report on business model innovation and investment opportunities of blockchain instry released by foresight Instry Research Institute, as of the end of 2016, there were 105 blockchain related enterprises in China, 80% of which were concentrated in eastern coastal cities, including Shanghai, Hangzhou and Taipei
from the perspective of global blockchain technology application development, as of April 2017, financial service companies accounted for 55.43% of the 267 blockchain venture capital companies; From the perspective of the Chinese market, 34 of the top 50 blockchain venture capital companies in 2016 are involved in financial services, mainly in cross-border payment, bill discounting and financial service platform<
analysis of the development trend of blockchain
the combination of blockchain and cloud computing is more and more close, and baas is expected to become a public trust infrastructure
cloud computing is the general trend. We believe that the combination of blockchain and cloud is also an inevitable trend. There are two modes for the combination of blockchain and cloud, one is blockchain in the cloud, the other is blockchain in the cloud. The latter, namely baas, blockchain-as-a-service, refers to that the cloud service providers directly provide blockchain as a service to users. In the future, more and more cloud service enterprises will integrate blockchain technology into the ecological environment of cloud computing. By providing baas function, they can effectively rece the deployment cost of enterprise application blockchain and rece the initial threshold of innovation and entrepreneurship
the security problem of blockchain has become increasingly prominent, and security protection needs the overall consideration of technology and management
blockchain system is almost perfect mathematically, with the advantages of openness and transparency, difficult to tamper, reliable encryption, anti DDoS attack, etc. However, from the engineering point of view, its security is still restricted by infrastructure, system design, operation management, privacy protection and technology update iteration. In the future, we need to consider the overall situation of technology and management, strengthen basic research and overall protection, so as to ensure the application security
the competition of blockchain is becoming increasingly fierce, and patent competition has become an important field of competition
with the increase of participants, the competition of blockchain will become more and more fierce, and the competition is all-round, including technology, mode, patent and other dimensions. We believe that in the future, enterprises will strengthen the layout of blockchain patents. Since 2014, the number of blockchain patent applications has grown explosively. Blockchain patents are mainly distributed in the United States in North America, the United Kingdom in Europe, China and South Korea in Asia, and this pattern will be maintained in the future. The patent gap between China and the United States is narrowing, and the number of applications in China in 2016 has surpassed that in the United States. It can be predicted that the patent competition of blockchain will become increasingly fierce in the future
with the acceleration of domestic policy process, the development of the instry ushers in a new opportunity
blockchain has attracted attention from all walks of life e to its core advantages of high performance, high security, high-speed access, efficient operation and so on. In the context of the rapid development of blockchain, China conforms to the needs of globalization, closely follows the international pace, and actively promotes the research, standardization and instrialization development of domestic blockchain related fields
trustworthiness is the core requirement of blockchain, and the importance of standards and specifications is becoming increasingly prominent
in the future value delivery network based on blockchain, we will completely use algorithms and software to build the trust foundation. However, we believe that this is far from enough, and we need the standard to increase the credibility of the blockchain. In the future, the standard of blockchain will standardize the technology and governance of blockchain from the perspective of users, business oriented, and from the dimensions of smart contract, consensus mechanism, private key security, and authority management, so as to enhance the credibility of blockchain and add weight to the trust of blockchain.

4. 1) First of all, it defines the technical value and positioning of the blockchain. As I said at the beginning, the positioning of the blockchain should take the blockchain as an important breakthrough for core technology and independent innovation
2) blockchain, Internet and artificial intelligence should be regarded as technologies of the same height, and blockchain should formally enter our hard science and technology development category
3) pointed out the development and application direction of our blockchain, including the speech that the technology of blockchain has extended to many fields, such as digital finance, Internet of things, intelligent manufacturing, supply chain management, digital asset trading, and so on. In terms of application, there will inevitably be some regulatory or legal problems in the process of application, What are the instructions in this speech? He mentioned that we should implement the rule of law in the management of blockchain, and promote the safe and orderly development of blockchain
4) in the more important point of application and development, it is mentioned that the blockchain is from virtual to real, enabling entity, improving people's livelihood, obtaining instrial advantages, and better serving the development of the whole instrial economy. In fact, through the study of blockchain technology, from one side or the signal released, we express our attitude towards the innovation and leadership of blockchain. We hope that in the development of blockchain, we can first have our own core technology, and we should be a leader in today's fierce international competition
5) it is to enhance the market confidence of the whole blockchain instry, especially for the application and development of the whole blockchain technology. With a great increase in market confidence, it is bound to attract more people in the next period of time, including the capital market and for example, more talents and research applications will enter this field. More capital, more manpower and more other social related aspects, including the rule of law and legislation, will positively promote the application and landing of the whole blockchain technology. These are my four points of view or summary of blockchain technology learning
if you have been concerned about blockchain for a long time, in fact, from the national level, including the 13th five year plan, blockchain technology has been written into the 13th five year plan, which is developed as a parallel technology with artificial intelligence, big data and cloud computing. It has been introced in the second half of 2018, and the office of network information technology has put the blockchain application service on record, From all aspects, it is actually a positive guidance or protection for the development of the whole blockchain
of course, when it comes to blockchain, you may also say that blockchain always thinks of money speculation and so on. In fact, digital currency is only a relatively narrow field in the field of blockchain. We now include support from the mainstream of modern society or the national level, and more support for the application of blockchain technology in the real instry, The core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in the distributed system without mutual trust by means of data encryption, timestamp, distributed consensus and economic incentives, so as to solve the common high cost and low cost problems 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.

7. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block
it can be used in practice:
virtual currency: for example, bitcoin, etc.
Digital Rights: it can authenticate works, prove the existence of text, video, audio and other works, and ensure the authenticity and uniqueness of ownership
public welfare: the relevant information in the public welfare process, such as donation projects, collection details, capital flow, feedback from recipients, can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision.

8. With the increasing maturity of blockchain, more and more enterprises begin to look forward to using this technology for innovation. So, what is the impact of blockchain on enterprises? What can it bring to enterprises<
Renren blockchain technology services
blockchain has the ability to innovate trade, transaction and business processes
the two basic concepts supporting blockchain are "business network" and "account book" -- it is thanks to these two concepts that blockchain can become a wise and unchangeable way of trade, transaction and business process execution
network members exchange various assets through an account book that can be accessed by all members. When the network synchronizes the account book, all members need to confirm the transaction of tangible or intangible assets. This shared view helps to establish legitimacy and transparency, even when the parties are not familiar with each other
blockchain can improve visibility and trust in business
by providing visibility to all participants, blockchain can rece transaction settlement time from days or weeks to seconds. The technology can also eliminate the intermediate third party that is usually needed to verify transactions in the past, so as to rece the excessive cost
because blockchain is built on the concept of trust, it can help enterprises rece the risk of illegal behavior on the payment network, thus helping to rece fraud and cyber crime
speed, cost, efficiency and transparency are the most important advantages of blockchain within enterprises and in the company ecosystem where trade activities are carried out. It is precisely because of such advantages that far sighted enterprises are more looking forward to using blockchain technology to innovate infrastructure and better carry out business
the value of blockchain development lies in the growth of the ecosystem
as a business network, blockchain can accommodate a variety of different types of participants. According to the number of participants in the blockchain network, the value of the assets exchanged, and the need to authorize members with different credentials, the adopters of blockchain technology should pay attention to the differences between "licensed" and "unlicensed" blockchain networks
when these business networks continue to expand, the real value of blockchain will be realized. With a strong ecosystem, business networks can reach critical scale more easily, enabling users to build new business models and innovate transaction processes.

9. Development trend:
1. Development trend of core key technologies
from the point of view of the current technology and application of blockchain, its core is distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other existing computer technologies. With the deepening of blockchain application, new and higher requirements will be put forward for these core technologies. The research results in consensus mechanism, security algorithm, privacy protection and other related technology fields will play an important role in the leapfrog development of blockchain technology and application, and will be very critical to the continuous innovation and breakthrough of these technologies
(1) the development trend of consensus mechanism
in the public chain, the common consensus mechanism has the disadvantages of low performance and high energy consumption“ The "side chain" technology can only solve some problems under certain conditions. At present, most of the mainstream consensus mechanisms in alliance chain are based on pbft and its variants. Although access control can greatly improve the performance, it also sacrifices the efficiency, constraints, fault tolerance and other aspects of the consensus. It can be predicted that consensus algorithms and decision-making with universality and better performance for some typical scenarios will continue to appear
(2) the development trend of security algorithm
security is particularly important for financial application systems. On the one hand, most of the traditional security algorithms currently used have potential "backdoor" risks, which need to be replaced by more secure national security algorithms, and the strength of the algorithms also needs to be upgraded; On the other hand, we should also prevent some new technologies, such as quantum computing, from impacting or even subverting the traditional security algorithms
(3) development trend of privacy protection
at present, the privacy protection related to blockchain is still relatively weak. Especially for sensitive data, we need to balance privacy protection and compliance supervision. Information privacy protection technology, such as zero knowledge proof, homomorphic encryption, is also an important direction of follow-up development
the above core technologies tend to be low-level computer technologies, and their development requires considerable personnel and time investment, which will be a progressive process. The research achievements and cooperation of related enterprises, scientific research institutions and colleges and universities in these fields are very important for the development of blockchain technology
2. Development trend of general development platform
at present, many IT enterprises, consulting companies, communities and technology alliances have invested in the application research and development of blockchain, established and improved the general development platform, which has a great role in promoting the application of the whole blockchain technology
similar to IAAs (infrastructure as a service) and PAAS (platform as a service) of cloud computing, the blockchain general development platform is composed of infrastructure support layer, blockchain core component service layer, and corresponding development test suite, which can provide one-stop, low-cost technical services for building and deploying blockchain applications. At present, there are some such platforms. With the rapid development of blockchain applications and the strong investment of relevant participants, its service coverage, R & D convenience, operation and maintenance intelligence, as well as high stability, large capacity and low cost are the predictable development direction.

The research achievements and cooperation of related enterprises, scientific research institutions and colleges and universities in these fields are very important for the development of blockchain technology
2. Development trend of general development platform
at present, many IT enterprises, consulting companies, communities and technology alliances have invested in the application research and development of blockchain, established and improved the general development platform, which has a great role in promoting the application of the whole blockchain technology
similar to IAAs (infrastructure as a service) and PAAS (platform as a service) of cloud computing, the blockchain general development platform is composed of infrastructure support layer, blockchain core component service layer, and corresponding development test suite, which can provide one-stop, low-cost technical services for building and deploying blockchain applications. At present, there are some such platforms. With the rapid development of blockchain applications and the strong investment of relevant participants, its service coverage, R & D convenience, operation and maintenance intelligence, as well as high stability, large capacity and low cost are the predictable development direction.
10. To tell you the truth, I don't understand this block key technology, but I think it's pretty good.
