Block not on the chain
compared with developed countries, China's insurance instry has developed for a short time, and the coverage rate of indemnificatory business, especially insurance types such as accident, serious illness, fixed life insurance and family property, is low, which makes it difficult for low indemnificatory and special groups to seek risk protection procts. In this reality, as a supplement of social security and commercial insurance, network mutual assistance can provide a group heating option for the low security group, which has a positive insurance inclusive effect. Yang Yong said, "blockchain technology can be applied to all aspects of social innovation. Our vision is to provide low-cost and adequate personal and property protection for the people who need protection most in China, so that insurance can benefit the public. After that, we are willing to open up this technical solution, so that more fields can benefit from the popularization of blockchain technology. "
Let's suppose villagers Lao Wang and Xiao Li. Lao Wang borrowed some money from Xiao Li, who wrote it in an IOU signed by both parties. A few days later, Lao Wang denied the existence of borrowing money and claimed that Xiao Li forged the paper. Xiao Li can't argue because he finds it difficult to prove that Lao Wang actually owes him money
in this example, Lao Wang and Xiao Li are two nodes
now assuming the same scenario, there are many pairs of people trading with each other in the village. The only evidence for each pair is the IOU. If one party fails, it will be difficult to do so. Seeing this scene, the village head came up with a solution. He suggested using a common notebook for the whole village to record all the transactions. Due to the high prestige of the village head, the villagers unanimously decided to let the village head keep this important transaction book. Each transaction, the villagers go to the village head's home, let the village head witness and record, each transaction is written into a notebook, and then safely saved. That notebook can be called a database
because this notebook is very important, the village head locked it in the safe. However, there are always some problems. Sometimes, the village head will accidentally sprinkle ink on the paper, making some transaction records illegible. This is called a single point of failure. The thief knows that there is an important notebook in the safe of the village head's house. He tries his best to steal it. This is called hacking
until one day, the village head's son owed others a lot of money, so the village head secretly deleted his son's debt entry. In this way, the village head's son "does not owe money."
when the villagers knew this, they began to question the fairness and authority of the village head. So some people put forward a new idea:
abolish the power of the village head, which is called decentralization. Let all villagers keep a notebook, and the transaction records are copied and distributed, which is called distributed database. Therefore, if there are n people in the village, there are n notebooks, that is, n nodes. Every time there is a trade between any two people, all the people in the village get together and record it in their notebooks. And no one can cover the sky. This is called decentralization
they also decided that they would never delete the mentioned transactions from their notebooks, which is irreversible. For example, Lao Wang borrowed a sum of money from Xiao Li before, but in the twinkling of an eye, he wants to return the money. Then the transaction book will not delete the previous borrowing record, but write a new repayment record, so there are two records
next, let's try to break this rule. What if we bribe Lao Wang to change his notebook? It's not feasible, because the next time the villagers meet, they find that Lao Wang's notebook is different from everyone else's, so the villagers notice that Lao Wang may be engaged in an indescribable transaction, and decide to abolish Lao Wang's transaction record and kick Lao Wang out of the organization
What if you try to bribe all the villagers? It's too expensive
the characteristic of this model is that greedy people need to pay a lot to attack the rules. He will find it more profitable to follow the rules
a smart child in the village suggested that each transaction data be called "block" and linked into a "chain" in chronological order, which is called blockchain
Musk's main purpose is to promote bitcoin better. He has promoted bitcoin to the outside world many times before it is well known that musk likes bitcoin. He not only uses his own money to buy bitcoin, but also uses bitcoin as the reserve capital currency of his company. This time, musk changed his nickname to currency master, obviously in order to better promote bitcoin. Musk also said earlier that it would consider receiving bitcoin to trade Tesla in the future. It is also driven by musk that the price of bitcoin has been rising since last year, reaching record highs repeatedly
for example, when you are hospitalized and discharged from a hospital, you need to queue up to go through a lot of proceres, such as printing the flow details ring hospitalization, for example, going through the discharge settlement proceres, for example, going through the medical insurance settlement, and so on. Without half an hour, these proceres can't be completed. Because once you go through the discharge proceres, in fact, it is equivalent to the end of the hospital proceres. When it comes to medical insurance settlement, it is not only the hospital system, but also the medical insurance system. At present, the data systems of the two departments can not be directly connected, so they need to queue up to handle it by themselves
the blockchain can provide a distributed accounting mode. Under the protection of cryptography knowledge, you can not only share data with other companies, systems and departments, but also ensure that the data is owned by you. Through distributed accounting, you can achieve cross department cooperation and real-time settlement
after being linked, all information is open and transparent, and any information can be found in the block.
the application of AI Artificial Intelligence has given birth to service robots. Service robot covers a wide range, including medical, logistics, agriculture, commerce, civil and other aspects. Through the use of AI technology, through data collection, analysis and calculation, service robot can learn human behavior, understand human intention and cooperate with human< According to IFR calculation, the global robot market in 2017 reached US $23.2 billion, of which the instrial robot market reached US $14.7 billion, with 85 robots per 10000 people. The rest is the service robot market, with a market size of US $8.5 billion
by 2030, the robot market is expected to reach 102.8 billion US dollars, about 20% of the smartphone market. Service robots will reach US $56.1 billion, maintaining a compound annual growth rate of 16%, which is faster than that of instrial robots. After two years of rapid development in 2017 and 2018, the number and amount of financing in the artificial intelligence instry in 2019 showed a precipice like decline, capital concentrated in the head enterprises one after another, and the survival of small companies was difficult. Even the head companies have encountered obstacles on the way to listing, and the news of layoffs is constantly shrinking. From the external environment, everyone's life is not easy
cheetah global think tank believes that the future of artificial intelligence is not always full of flowers and applause. If artificial intelligence really wants to lead the next decade, it must be that practitioners abandon the flashy valuation, focus on procts, take root in technology, and strive for the realization of the scene overnight

if you want to establish a biography for artificial intelligence, 2019 is destined to be a different year of seeking normality. Difficult and awkward, rooted and stick to, multiple complex emotions interweave in this year
difficult! After two years of rapid development in 2017 and 2018, the number and amount of financing in the artificial intelligence instry in 2019 showed a precipice like decline, capital concentrated in the head enterprises one after another, and the survival of small companies was difficult. Even the head companies have encountered obstacles on the way to listing, and the news of layoffs is constantly shrinking. From the external environment, everyone's life is not easy
awkward! 2019 is also a year of disillusionment. Artificial intelligence was once seen as the next opportunity to create a 10 billion dollar giant after the mobile Internet. But in 2019, before the arrival of general artificial intelligence, it is not as versatile as people think. The public's enthusiasm for artificial intelligence has also decreased a lot. How many people are still concerned about the man-machine battle between Li Shishi and Korean go AI "Han Dou" in December this year<
we should cultivate grain, build high walls and become king slowly. Cheetah global think tank believes that the future of artificial intelligence is not always full of flowers and applause. If artificial intelligence really wants to lead the next decade, practitioners must abandon the flashy valuation, focus on procts, take root in technology and seize the day in the scene
next, cheetah global think tank will comprehensively scan the development of artificial intelligence in 2019 from the aspects of policy, capital, technology, intelligent service robots, AI application scenarios, etc., trying to show you a more comprehensive commercialization of artificial intelligence in 2019.
thanks to the soaring bitcoin. Those who held bitcoin a few years ago are now laughing; People who don't have bitcoin in their hands are envious at the price of bitcoin
experts tell us that bitcoin is a virtual currency based on blockchain technology. But to ask what blockchain is, at most some people will answer: This is a kind of smart contract. And then? Little is known
but it doesn't seem to get in the way of people's attention and enthusiasm. At one time, a variety of virtual currencies and procts based on blockchain were born. People were chasing each other, and they didn't have time to know whether they were real or not. "Get on the bus first, and you won't have a chance later." this is the attitude of many people in the face of blockchain
in fact, blockchain is a decentralized distributed ledger database. Moreover, the impact of blockchain has long gone beyond the scope of virtual currency. Open a conference activity website, the number of meetings and activities about blockchain has increased significantly, "blockchain finance", "blockchain energy", "blockchain advertising"... In just a few months, blockchain seems to have reached the point of being able to cover everything
the role and value of blockchain are getting more and more recognition. However, has the blockchain really been able to exert such a great influence? Many people in the instry said that the current blockchain is still in its infancy, and many aspects need to be improved
therefore, we should be alert to following suit and hyping the concept of blockchain. In the current development stage of blockchain, not all fields can realize "blockchain". It is necessary to prevent new bottles of old wine, especially the behavior of touching the regulatory red line
before, there was a company that divided the property right of the house and put it on the blockchain platform to allow investors to trade through token. The investors bought a share of the property right. Although this business model has well applied the idea of blockchain, because token is suspected of illegal financing, which seriously disrupts the financial order and touches the red line of supervision, it has been stopped
the development of everything needs to be graal. Take big data, which became popular a few years ago, for example. Up to now, there are still some places that simply believe that the development of big data is to buy more and more servers. It can be seen that the development of big data still needs time, needless to say the newly emerging blockchain
at first glance, it is technology that brings the world to a better distance. Behind it must be people. In order to play its e role, blockchain must first have "people" to make some constructive attempts and explorations. But in terms of the current development of blockchain, we still need to do a lot of preparatory work.
