The lowest price of blockchain technology market
in the Internet era, there is a database behind every system. This database can be regarded as a large account book. In the past, the person who maintained the system was responsible for managing the database and recording the user's behavior, that is, bookkeeping. However, the blockchain is "decentralized", which allows every member of the system to participate in it, not only everyone bookkeeping, but also through links, Everyone can have a complete account book
"blockchain is essentially a collective recording mode. What's special is that it adopts a set of techniques in an ingenious way to realize the authenticity and credibility of the recorded results, which is difficult to destroy and tamper with. " Zhang Xiaorong said, "first, everyone has the right to record and authenticate with each other to distinguish the true from the false, which is called consensus mechanism; Second, no one can tamper with the records, because there are cryptographic signatures; Third, everyone has a , so even if some account books are damaged, the whole will not be affected. This is called distributed storage. The information recorded in this way is presented in block mode according to the time chain, so it is called blockchain. "
various cryptocurrencies represented by bitcoin are originally an application of blockchain technology, which can be described as blockchain version 1.0. However, around 2014, the instry began to realize the important value of blockchain technology. Blockchain graally separated from digital currency and applied to various economic and social fields other than digital currency
it has broad application prospects
blockchain technology is considered as a disruptive innovation after steam engine, electric power and Internet. If the steam engine and electricity liberate the proctivity, and the Internet has changed the way of information transmission, the blockchain, as a machine for building trust, may change the way of value transmission
for example, in the financial field, the cost of reconciliation, clearing and settlement between financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. The application of blockchain technology can help rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing speed and efficiency of payment business, It also makes small cross-border payments possible. In December 2017, China Merchants Bank completed the RMB position transfer business from Hongkong Wing Lung Bank to Shenzhen Branch of Wing Lung Bank. This is the world's first interbank cross-border RMB clearing business based on blockchain technology
in addition, according to the white paper 2016 on China's blockchain technology and application development issued by the Ministry of instry and information technology of China, the application of blockchain has been extended to medical and health, ecation, charity, social management and other fields. Taking the cultural instry as an example, the low cost of reproction, the high cost of safeguarding rights, and the difficulty of providing evidence make the protection of intellectual property rights a pain point for the instry. With blockchain, the proction, dissemination and transaction records of cultural procts are true, transparent and reliable, and the problem can be solved
Zhang Xiaorong said that blockchain technology has solved two major problems in the era of Digital Economy: one is the visible flow direction, and the other is zero trust cost. In the past, the circulation of physical paper money was invisible, but the flow of all digital assets had a "chain" to check. Yang Yanchao, a researcher at the intellectual property center of the Chinese Academy of Social Sciences, also believes that the biggest advantage of blockchain is that it has truly completed the credit construction in an anonymous society, bringing new opportunities to many fields, thus making various innovative applications possible
there is a long way to go in the future development
in terms of technology promotion, there is no big barrier to blockchain, which has been confirmed in the global practice of bitcoin, and its main resistance comes from the obstacles in concept and implementation
"on the one hand, the society may be very concerned about the" naked "state in the blockchain. Blockchain has built a "Skynet" for the commercial society. The company's economic activities are all recorded, so there is no secret to speak of. In this way, some business strategies may not be implemented under the blockchain. "
"on the other hand, the current legal system lags behind the development of information technology, so how to put the emerging blockchain technology under the legal supervision needs to be studied." Duan Yongchao said
the core of blockchain is decentralization, which will have an impact on the long-standing central management model. In addition to the law, how to establish a regulatory environment that can promote the application of blockchain technology, so that the technology can benefit the society and not be used to do evil, is also an urgent problem to be solved.
There is no doubt that blockchain has development prospects, and the necessary condition for development prospects is to enter the mainstream market
North America blockchain infrastructure the oan (former aion network) founder and CEO Matt spoke published an article entitled "in order to successfully enter the mainstream market, blockchain projects must" eat dog food "in Forbes on July 24, in which Matt mentioned his views on how blockchain should enter the mainstream market - & quot; Eat dog food
in the science and technology circle, there is a jargon called & quot; Eat dog food Dogfood (also known as eating your own dog food) refers to companies using their own procts and becoming users of their own procts. Many high growth companies (such as Microsoft, Facebook, Amazon, apple, Netflix and Google) also test their procts by "eating dog food" or help build credibility“ "Eat dog food" is often used to find and fix bugs, but it has another value: to create reliable use cases for the company's procts
this is worth learning from blockchain projects, because blockchain projects often hold & quot; Once built, they (users) will come naturally, which habitually leaves the responsibility of creating new and interesting blockchain applications to a third party
this attitude is very common, even the well-known blockchain summit consensus 2019 also held a conference entitled & quot; Once built, they (users) will naturally come: to build a global blockchain Center & quot; To discuss how governments around the world can make efforts to attract blockchain projects while balancing regulatory, investment and innovation needs
to be fair, this strategy may be effective for blockchains that only focus on people in the currency circle. For the security token, especially for the exchange represented by the transaction, it makes more sense - "supply creates demand" is the usual idea here, especially considering that the realization of these transactions requires the construction of complex infrastructure
in contrast, "eat dog food" is more likely to be adopted by blockchain project developers who seek mainstream audiences (such as those in financial instry, manufacturing and supply chain, identity management, etc.). If blockchain technology wants to enter these mainstream fields, blockchain companies must first "eat dog food". This can not only clearly prove that blockchain technology is feasible outside the coin circle, but also highlight that blockchain can not only optimize existing use cases, but also create new use cases
and the oan team has been adhering to this concept, and relying on the oan and aion's technology stack built over the years, it has developed a financial technology platform moves for independent workers
Matt said that in the development and development of moves, the team hopes that the relevant functions of the OAN blockchain network can be brought into full play, so it will focus on the following three aspects:
1. How to use the OAN blockchain network to improve the credit efficiency of the proct there are two main considerations to improve credit efficiency: 1) can we use the mechanism of the defi market to rece the cost of capital; 2) Can the blockchain technology be used to increase the external trust in the credit process of moves. Here, moves will form a mechanism of "pooling wisdom", so that everyone can contribute to recing credit risk and increasing the credibility of credit process, and may even develop a micro guarantee mechanism in the future. Therefore, users will be able to participate in the market established by the platform as borrowers, lenders or guarantors
specifically, by connecting moves with the oan network, and with the help of digital asset aion, a relationship of interest consistency is formed between procts and users, so that users can personally experience the success of moves procts and directly participate in the oan, a blockchain network supporting moves
3. How to create the first open system of financial reputation data with moves
this open system may become a substitute for traditional credit scores or related mechanisms. Over the years, banks and financial institutions have been using Equifax, Fico or other similar institutions' scores as risk indicators, and the moves team believes that the procts they are building will be a good start - the beginning of a more perfect and modern financial reputation system. This is a long-term goal
moves supports North American mainstream carpooling, take out and other casual work economic platforms, and will be the flagship open application developed by the oan on its blockchain network. In June, moves expanded its operations from Ontario to Alberta and British Columbia into western Canada
all the initiatives of the oan team adhere to the spirit of "eating dog food" and strive to make blockchain technology enter the mainstream market as soon as possible. Blockchain is not for the minority, but for the mainstream. In addition to the oan team, many projects and institutions in the blockchain instry are also aiming at this goal. Can you say that such an excellent and targeted blockchain has no development prospects
blockchain technology has the following four ways to make money:
1. Hardware and infrastructure. A typical one is mining machinery proction and distribution chain, where you can make money by buying mining machinery and digging
2. The underlying platform of blockchain and common technologies, such as Ethereum and other public chains, and the privacy protocol nucypher, where you can make money by investing in its token, building applications on the chain, and providing services for users
3. Various vertical applications, such as supply chain traceability and Finance Based on blockchain, right confirmation and trading, can be used or invested to make money
Service facilities, such as digital asset exchange and wallet, media procts, etc., you can make money by making your own exchange
{rrrrrrr}
extended data:
type of blockchain
1. Public blockchain
refers to: any indivial or group in the world can send transactions, and the transactions can be effectively confirmed by the blockchain, Anyone can participate in its consensus process
public blockchain is the earliest and the most widely used blockchain. The virtual digital currencies of bitcoin series are all based on public blockchain, and there is only one corresponding blockchain in the world
2. Consortium block chains: multiple preselected nodes are designated as bookkeepers within a group, and the generation of each block is jointly determined by all preselected nodes (preselected nodes participate in the consensus process), and other access nodes can participate in the transaction
3. Private blockchain
private blockchain: it only uses the general ledger technology of blockchain for bookkeeping. It can be a company or an indivial, and only enjoys the write permission of the blockchain. This chain is not very different from other distributed storage schemes
Original title: China's blockchain instry market status and development trend analysis in 2019, widely used to accelerate the construction of Digital China. Basically, a relatively mature instrial chain has been formed. With the promotion of national policies and the increasing demand of downstream application fields, the market scale of China's blockchain instry is constantly developing, the regional concentration is high, and the instrial cluster effect is obvious. With the increasing maturity of blockchain technology, the blockchain instry is entering the 3.0 stage as a whole. It has a good performance in finance, logistics, right protection and other fields, and has made great contributions to promoting China's digital construction and accelerating the process of Digital China
instrial chain analysis of blockchain instry: there are many downstream application fields with huge development potential
from the perspective of instrial chain, China's blockchain instry includes upstream hardware, technology and infrastructure; Midstream blockchain application and technical services
application fields of downstream blockchain. The upstream hardware, technology and infrastructure mainly provide the necessary hardware, technology and infrastructure support for blockchain application. The hardware equipment includes mining machinery, ore pool, chip manufacturer, etc; General technologies include distributed storage, decentralized transaction, data service, distributed computing and other related technologies
the downstream application fields include the combination of application blockchain technology and existing instries, mainly including financial instry, logistics instry, right protection, medical health, instrial energy and many other fields. As an emerging technology, blockchain has many downstream application fields and great development potential
the application and service of midstream blockchain includes the construction of infrastructure platform and the provision of technical service support. The construction of infrastructure platform is divided into general infrastructure chain and vertical domain infrastructure chain; Technical service support includes technical support and service support. Similar to upstream technology, technical support is responsible for providing buyers with a series of technical support based on blockchain procts, such as blockchain security protection; Service support includes a series of services such as digital asset trading place, digital asset storage, media community, etc
instry chain analysis of blockchain instry Most of 360 and other enterprises use their own financial companies to apply blockchain technology to launch a new mode of blockchain + finance and broaden the application scenarios of blockchain technology
With the continuous development of China's blockchain technology and the continuous expansion of blockchain application fields, China's blockchain instry will become the forefront of global technology development and open up a new international competition track in the future2. 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
4. Blockchain creates a new platform economy and opens a new era of sharing economy
5. Blockchain accelerates the process of "credible digitization" and drives finance to "move from virtual to real" to serve the real economy
The blockchain supervision and standard system will be further improved, and the instrial development foundation will continue to be consolidated1. The "load" in dispatching is the electric quantity, unit: degree, also is kilowatt hour, kW & 8226; h;
load is not a constant value, but a variable value with time. Because the electrical equipment does not run at the same time, even at the same time, not all can reach the rated capacity. In addition, the working system of each electrical equipment is different, including long-term, short-term and repeated short-term
2. "Load" used in power flow calculation refers to the outgoing power flow of a node, which is the power
S=P+jQ
where p is active power
unit: W, kW, MW
q is reactive power, unit VaR, kvar, Mvar
s is complex power, unit VA, KVA, MVA
in design, if the capacity of each electrical equipment is simply added up as the basis for selecting conctor, cable section and electrical equipment capacity, the equipment will be under loaded, resulting in a waste of investment and non-ferrous metals; If it is too small, overload operation will occur
the result is either uneconomic, or overheating insulation damage and line loss increase, which will affect the safe operation of wires, cables or electrical equipment, and even cause fire accidents. Therefore, the load calculation is only close to the actual capacity
the total load of power system is the sum of the total power consumed by all electrical equipment in the system; By adding the power consumed by instry, agriculture, posts and telecommunications, transportation, municipal administration, commerce and urban and rural residents, the comprehensive power load of power system can be obtained; The power of comprehensive power load plus network loss is the power that each power plant in the system should supply, which is called the power supply load (power supply) of power system; The power supply load plus the power consumed by each power plant itself (i.e. auxiliary power) is the power that should be generated by each generator in the system, which is called the generation load (generation capacity) of the system
the load is a random change, every time the electrical equipment starts or stops, the corresponding load will change, which can be found to have a certain regularity to some extent. For example, some loads change to a certain extent with seasons (summer and winter) and enterprise working system (one shift or shift operation). The regularity of its change can be described by load curve: the so-called load curve refers to the graph of active and reactive load changing with time of electrical equipment in a certain period of time, which constitutes active load curve (P) and reactive load curve (q) respectively
By the end of 2019, the number of blockchain research institutions in China has reached 97. In addition, domestic colleges and universities have arranged blockchain technology research, strengthened theoretical knowledge innovation of blockchain technology, and improved their blockchain technology R & D capability. By the end of 2019, there are 24 colleges and universities in China participating in strengthening blockchain technology R & D. The core technologies are mainly distributed in consensus algorithm, cross chain, underlying architecture and multi chain
in 2020, the blockchain instry will be further standardized
in 2020, China's blockchain policy will continue to be favorable, the standards and specifications will be more perfect, the instrial scale will continue to grow, the technology will continue to innovate and develop, and the application demonstration effect in key fields will accelerate. At the same time, according to the problems existing in the development of China's blockchain in 2019, CCID blockchain Research Institute puts forward six suggestions: accelerating the formulation of top-level design, establishing and improving the regulatory system, accelerating the innovation and development of core technologies, promoting the third-party evaluation and certification, strengthening the cultivation of professional talents, and accelerating the implementation of applications in various fields
