The industrial revolution led by new materials of blockchain
the most valuable part of blockchain is not technology, but the idea behind it.
no technology is omnipotent, so is blockchain technology. As a trust connector, the greatest value it brings to the times is the concept of openness, openness and transparency behind it, and the spirit of building a business with trust and honesty. Based on this spirit, the blockchain technology is like the most impartial machine judge, so that every information in its hands can exist permanently in the world and be tested by future generations.
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.
With the rapid development of science and technology, our society has been greatly changed. In the historical process of human development, we have experienced several instrial revolutions, each of which will be a great change. Many people will ask, which technology is most likely to lead the fourth instrial revolution? The answer to this question is most likely to be the new computer system and artificial intelligence. Let's analyze it in detail
The social security bureau goes to work at 8:30 in the morning, 12:00 at noon, 2:30 in the afternoon and 5:30. The Social Security Bureau doesn't work on Sunday, so we have to go to the local medical insurance center to apply for the new medical insurance certificate. And to bring ID card or household register and other valid documents
there are differences between medical insurance center and Social Security Bureau in concept and function:
first, concept
Medical Insurance: medical insurance is medical insurance, which is included in social insurance
Social Security: social security is social insurance, including pension social insurance, medical social insurance, unemployment insurance, work-related injury insurance and maternity insurance
Medical insurance: medical insurance mainly provides medical security for the insuredSocial Security: social security is a government action, which is mandatory and provides five kinds of economic security for the insured
extended data
social medical insurance is a social insurance system established by the state and society according to certain laws and regulations to provide basic medical needs for workers within the scope of insurance
the composition of social overall medical insurance: the payment base is m: employee wage income + allowance. The unit pays 8% m every year; Employees pay 2% m per year
characteristics of medical insurance:
it has the characteristics of "low level and wide coverage". The payment is subject to the expenses that the vast majority of low-level units and indivials can bear. It covers all units and employees in cities and towns, and employees of different types of units can enjoy the right of basic medical insurance. The insured can enjoy it for life after completing the payment period. Secondly, the basic medical insurance has the characteristics of "the burden of both sides, the combination of unified accounts"; It is based on the principle of "determining expenditure by revenue and balancing revenue and expenditure"
in China, social insurance is an important part of the social security system, and it plays a core role in the whole social security system. In addition, social insurance is a kind of payment social security, the funds are mainly paid by employers and workers themselves, and the government financial subsidies and bear the ultimate responsibility
However, only when the workers fulfill the legal payment obligations and meet the legal conditions, can they enjoy the corresponding social insurance benefits The function of social security: first, social insurance system as an important tool of demand management plays a positive role in the economy; Second, the effective use of social insurance fund can promote the sustained prosperity of economy; Third, social security has become the basic condition for enterprises to attract talentsThe working unit of the medical insurance center is an institution. The working hours of the staff are the same all over the country. They leave work at 12 o'clock in summer and go to work at 3 o'clock. It's 12 o'clock in winter and 2 o'clock in winter. Now I still commute in winter, so I go to work at two o'clock
Working hours of Shanghai social security centers from Monday to Friday: 9:00 am to 11:30 am; 13:30-16:30 p.m; In addition, only consulting business is accepted from 11:30 to 13:30
I also go to work on Saturday, 9:00-16:30, but only accept personal business, including policy consultation, maternity insurance benefits application, personal online password application, etc. I don't go to work on Sunday

Medical insurance card reissue, social security center on the same day to do, generally can take the same day
social medical insurance card is short for medical insurance card or medical insurance card, it is a special card for personal accounts of medical insurance, and personal identification card is used as identification code, and detailed information about personal ID number, name, gender, account money, and consumption situation is stored, which is equivalent to ID card and social security card. Therefore, the holder must take good care of the medical insurance card
at present, some local social security cards in China have the function of medical insurance and can be used as medical insurance cards. However, some areas still need to hold a medical insurance card to see a doctor. If the insured accidentally loses the medical insurance card, he must report the loss in time

After the information is confirmed by the relevant personnel of the medical insurance center, the loss report is successful, and the settlement of the card can be stopped through the medical insurance network within 1 hour
if you can't remember the consultation number clearly, another way is to report the loss by calling the consultation service number of the issuing bank of the medical card, which is similar to that of the bank< (2) report the loss of medical card in writing through the medical insurance center:
if the information provided is wrong, resulting in unsuccessful report of loss by telephone, the insured should go to the relevant medical insurance center to report the loss of medical card in time.
