Xiaofeng blockchain and account revolution
Publish: 2021-05-23 02:57:50
1. It's a way to solve many formality problems. blockchain is decentralized and transparent. Now many payment channels are studying blockchain technology, maiteng
2. The first instrial revolution brought steam power and factories. For the second time, there were railways and electricity. The third time has given us the convenience of Internet, digital computer and modern world
these revolutions started and ended with the creation of better and more efficient machines. But the fourth revolution, the instrial Internet of things (iiot) asserts, is coming, and it will not follow in the footsteps of its predecessors
the fourth revolution will not focus on stronger and faster machines: it will focus on machines, processing, sharing and spontaneous information behavior, fundamentally changing our relationship with tools, the world and each other
the data revolution
is not coal, steel, nor silicon. The currency of the fourth revolution will be data
a single gas turbine, coupled to the instrial Internet, generates more than four times as much data in one day as the global Twitter as a whole, but the data we analyze is less than 1%. Bill RUH, chief executive of Ge digital, predicts that digital information will overflow, and today's analysis tools are hopeless
"ten years ago, we might have introced 1TB of data every day." "Today, it's up to about 10000 TB of data," RUH told the Boston Globe. By 2020, we expect to introce about 1 million terabytes of data a day. "
the data generated by future machines is about the same as that of the library of Congress. Imagine reading every book in the library of Congress and then having to summarize what you've learned on 10 pages. The task is not only huge, but also ridiculous
the real miracle of the fourth instrial revolution will not be to proce data, but intelligent machines that can analyze these data and communicate with their peers in the network. Each networked machine will then take action to change its processes to improve efficiency and feed back its changes to the network
I hope these smart machines will bring our world economy to a climax: RUH and Ge believe that in the next 20 years, the smart machines and Internet of things instry will add 10 to 15 trillion US dollars to the global economy. Given that global gross domestic proct (GDP) was about $74 trillion in 2015, this is a huge growth
the foundation of the revolution
for the coming revolution, there are two components that are important and necessary: a centralized, instry-specific Internet communication network, such as predix of General Electric; And systematic, decentralized way, and hinder dishonest communication to promote business development
the specific iiot network must act as a hub for intelligent machines to interact with each other and with human creators. Sensors on the computer collect a large amount of data, and then filter the data in real time. In other words, it can be imagined that it happened on the basis of a machine. However, the investigation results of relay equipment and the decision made without human intervention, in order to truly build an intelligent network, the machine needs a single communication network
imagine that when the aircraft is still in the air, the sensors of the aircraft engine recognize the part that is about to fail, and then communicate with the destination airport. The engine will need maintenance and order replacement parts before landing
this intuitive machine is not a science fiction dream: it's our future
in my opinion, iiot information network is only half the success, and ultimately it is about e-commerce. Seeing it as a public road, millions of autopilot cars will run on top one day.
now, these autopilot cars run on a single system. But how do we ensure that every autopilot will obey the traffic rules? For example, how can we ensure that the vehicle does not send fraud information about its whereabouts at the time of the accident? If there are only two parties involved in the accident, then each passenger will confirm the story of his own car, and there is no way to verify the position claimed by each party
considering that decentralized, satellite based GPS will affect the situation. The system is just and connected to every car. Of course, every car can continue to lie, but it's much easier to verify which side is telling the truth
e to the nature of the GPS system and the nature of its cancellation, the autopilot car has no reason or is tampered with by its owner. This strong incentive for integrity is to promote the trade between autopilot cars, and it is necessary for owners to feel that their investment in these vehicles is safe. Br />GPS technology is for auto driving vehicle, just like network block chain technology for instrial Internet. Of course, self driving cars can run on roads without GPS, but their owners probably will not allow them to do so. Similarly, on a larger scale, machines can communicate on a single, centralized network of the instrial Internet, but only when there is no risk Blockchain is the core part of bitcoin technology. Its function is simple and similar to an account book, recording all transaction data. This account book: 1. It is stored on each bitcoin node of the Internet, and each node has a complete backup; 2. It records all bitcoin transfer transactions since the birth of bitcoin; 3. The ledger is stored in blocks, and each block contains some transaction records. Each block will record the ID of the previous block, forming a chain structure, which is called blockchain; 4. When you want to initiate a bitcoin transaction, just broadcast the transaction information to the P2P network, record your transaction information as a new block and connect it to the blockchain, and the transaction is completed
blockchain has stimulated the revolution in other places
of course, blockchain has promoted the development of e-commerce in the financial instry. But digital information packets are discrete assets like money, and blockchain can create digital records of their existence and transmission. The technology is essentially a unified ledger of records or digital events. The ledger is distributed in the network and shared by different parties, and can only be updated by the majority of these parties. Once a ledger item is created, it can never be erased
blockchain is the missing link in the revolution, because the e-commerce it inspires will define the trust between machines and stakeholders. For example, Volkswagen's recent emissions scandal. VW's tests show that its vehicles emit too much NOx, so it chooses to hide the problem to avoid subsequent inspection
although blockchain will not prevent machines or people from tampering with data, it will create transparent, shared and indelible documents about the original emission data. If this data has been created and shared through the blockchain system, Volkswagen will never embark on the road of fraud, because the difference between the two data sets is obvious
the benefits of iiot are obvious. We have developed machine to machine communication technology; Now, it's the standardization challenge between society and the next revolution. This has driven the development of database technology in the past 30 years, and we have finally seen the momentum of construction
the first mock exam is different from the other enterprises, but if we all want to benefit from the high efficiency brought by the fourth instrial revolution, we must adopt the single mode of machine to machine electronic commerce. And because the communication network has to operate commercially between voluntary participants, we have to integrate the blockchain into this system. In the need to constantly modify the data, and free information trade needs detailed environmental conditions, blockchain is the best path to a new instrial revolution.
these revolutions started and ended with the creation of better and more efficient machines. But the fourth revolution, the instrial Internet of things (iiot) asserts, is coming, and it will not follow in the footsteps of its predecessors

3. What is the most essential difference in economic activities before and after the blockchain comes out
before blockchain, any transaction activity needs an intermediary. Without an intermediary, two strangers can not reach a transaction. Here comes the blockchain, replacing the intermediary with a robot, and using a set of mathematical algorithms to ensure that two strangers complete a transaction
blockchain is a machine of trust, which is its essence
"decentralization" is a result of blockchain. In economic transaction activities, the so-called "decentralisation" is nothing more than these meanings:
first, when we complete a transaction, we no longer need a third party, which is a center
secondly, all the economic activities on the blockchain no longer need the organization and system of "company" to help us complete various transactions
thirdly, when serving for a centralized organization, the centralized organization gives us jobs and wages to encourage us to better serve the cause, but the incentive mechanism on the blockchain is not established by the centralized organization.

4. From now on, the possibility of implementation is relatively small, perhaps because of this
5. One of the three conditions for large-scale implementation of blockchain applications is blockchain 3.0 technology, which can improve the performance, ease of use, operability and scalability of blockchain, and involves new technologies such as side chain, sub chain, cross chain, layering, fragmentation and zoning. According to Xiao Feng's observation, most of these technologies will mature in 2019, and the main network will go online. The launch of these new technologies is the premise of large-scale commercial application of blockchain. So from a technical point of view, after 2019, the large-scale commercial application of blockchain can be expected
the second is that only mature technology is not enough. In order to realize a large number of DAPP and commercial applications on the blockchain, we must be prepared on one hand: that is, the digital currency that can be used as payment tool, exchange medium, value measure and value storage. Xiao Feng said that everyone thinks that bitcoin is a payment system, but the real bitcoin can not meet our demand for payment because its currency value fluctuates too much
for example, he said that a mall sold a bottle of water and accepted bitcoin payment. When he got up the next morning, he found that 20% of the value was gone. So it can't be accepted. After the Japanese parliament made it clear that bitcoin could be used as a payment tool, some Japanese businesses announced that they would accept bitcoin payment. But later found that it caused a lot of trouble for the stability of the company's balance sheet. Your balance sheet is unstable, up or down. This not only affects the value of the things sold, but also affects the credit evaluation of enterprises and the services provided by banks to companies
the third condition is the construction of laws and regulations and supervision system. The digital economy on the blockchain must obtain legal protection and comply with the law. Xiao Feng stressed that there can be no decentralization in this regard
the differences between blockchain and Internet are discussed. He believes that the core difference between the two is that the Internet is a centralized trust mechanism, while the blockchain is a decentralized trust mechanism, and there is no need to trust a third party
the second core difference between the Internet and blockchain is the incentive mechanism, not the digital currency or the ability to issue currency. Economics has been discussing incentive incompatibility. Under the company system and on the Internet, the incompatibility of incentive mechanism has not been solved. However, in the decentralized blockchain, the blockchain achieves complete incentive compatibility. Without shareholders, board of directors and employees, the conflicts of interest between these roles will not happen again.

6. The era of blockchain 1.0 is the era of digital currency, and the technical basis is as follows:
1. Lianzhuang data block structure based on blocks
2. Network wide shared ledger
3. Asymmetric encryption
4. Source code open source
with the popularity of digital currency, many people also have a strong interest and start to speculate in currency, and a series of scams appear at the same time, Therefore, virtual currency is under strict supervision in China, but with the application and deepening of blockchain technology, the era of blockchain 3.0 has come. Behind the operation of all walks of life, we can see the mode of blockchain cooperation. Therefore, blockchain will change the way of human life widely and profoundly, so the whole life service will enter the era of blockchain. In the process of Internet development, blockchain + physical instry, blockchain e-commerce and blockchain community operation can be applied to blockchain technology.

7. 1. The value of bitcoin does not lie in its computing method and encryption algorithm. 2. The calculation and proction of bitcoin need time, equipment loss and electricity cost. 3. The total output of the algorithm is limited. 4. Some foreign and domestic objects have supported bitcoin payment, which makes it have the preliminary property of currency. 5. There is no difference between bitcoin and the legal currency of any country in its own value. A piece of printed paper or PVC does not have actual value. It can not have the characteristics of rare metals like gold. 6. The biggest risk of bitcoin is that no country, bank, military or government can guarantee its credibility. 7. At present, it seems to be just a virtual currency with speculation value. 8. Its circulation value is certainly not as popular as q-coin in China. For example, few people in second tier cities know about bitcoin, let alone let it admit its value.
8. To be sure, No. This is not a low configuration computer. This is the tablet configuration. You can understand it as the tablet with a keyboard,
if you don't know how to ask, please accept if you are satisfied
if you don't know how to ask, please accept if you are satisfied
9. 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. It is a technical way of accounting with the participation of the whole people.
