Block chain eliminates Taobao

1. As a kind of decentralized database, blockchain has the characteristics of openness, distribution and irreversibility. As an electronic data storage platform, blockchain has the advantages of low cost, high efficiency and stability. At present, blockchain has been applied in many fields and has brought many changes to our life. Now many electronic contract platforms, such as Fada This kind of blockchain technology has been applied in the chain of evidence, and the blockchain technology has also been accepted by the court

2. Blockchain is not broken. Blockchain itself is a kind of decentralized database, which can be accessed but not tampered with. Therefore, it is a very secure data chain

3. I'm very responsible to tell you that blockchain is definitely not a scam. First of all, the most talked about blockchain is digital currency. Here I want to state that there is no digital currency out at present. As you know, bitcoin, Ethereum, reborn, etc. are all digital encryption codes, and they don't have full purchasing power. At present, they are only in the stage of speculation. Blockchain is widely used in the future It will certainly overturn the existing economic model and affect the way of human life. Compared with the Internet, it will have a qualitative leap. Loser poor want to become a billionaire. This is the best shortcut. If you want to know more, you can continue to ask questions

4. The disappearance should be temporary, just as newspapers are still there after Internet news. However, the new technology will certainly bring some impact or even impact. Blockchain may affect the following 12 instry regions:
1. Banking
as a digital, secure and anti-interference account, blockchain realizes the core function of Banking: the safe storage and transfer center of value. In other words, in the next few years, a wave of companies based on blockchain technology may affect the banking instry. Indeed, UBS, a Swiss company, and baecelays, a British company, are trying to use blockchain technology to improve payment terms. Some other banking companies even said blockchain technology could save $20 billion in intermediate costs

therefore, it is not surprising that banks, as financial service giants, have become the growth force of blockchain venture. Payment and transfer
recently, the world economic forum wrote in Forbes magazine that decentralized payment technology, such as bitcoin, may change the "business structure" of the transfer instry that has not changed for more than 100 years. Blockchain technology can avoid complex systems and create a more direct payment process between the payer and the payee. Whether it is domestic transfer or cross-border transfer, this method has the characteristics of low price, fast speed, and no intermediate fees. Abra (above) is a start-up enterprise that uses blockchain technology for global bitcoin and blockchain based transfer
3. Network security
although the system of blockchain is public, advanced encryption technology is used in the process of data exchange such as verification and transmission. This technology not only ensures the correct source of data, but also ensures that the data will not be intercepted in the intermediate process. If the application of blockchain technology is more extensive, the probability of being attacked by hackers may also decrease. Therefore, people think that blockchain system is more secure than traditional system. One of the reasons why blockchain system can rece the traditional network security risk is that it relieves the demand for middleman
"eliminating middlemen not only reces the potential security risk of hacker attacks, but also reces the possibility of corruption," Goldman Sachs wrote. Guardtime (above) is an Estonian start-up company, which mainly studies instrial network security solutions based on blockchain technology
4. Academic record and academia
holbertson school, a California software skills program, announced that it will use blockchain technology to identify academic credentials. This will ensure the authenticity of holbertson school students in course identification. If more schools adopt such transparent certificates, transcripts and diplomas, academic corruption will be greatly reced, not to mention the labor verification time and paper document cost
5. Elections
at the University of West Virginia, the student union is considering whether to use a voting platform based on blockchain technology to conct school elections. If such a platform is used, students can vote with mobile devices, and the voting results will be included in the public system, so the voting is completely safe. One student who supported this way explained that the vote "can never be modified or deleted by us - programmers, school administrators or students."
Agora voting, a Spanish software project, uses encryption technology to improve the security of online voting. Several of their systems have also been tested in Spain. Recently, the leader of this project proposed several ideas to turn bitcoin and blockchain technology into voting applications, which are far from experimental
6. Car rental and sales
later last year, visa and DocuSign announced a cooperative plan to create specific solutions for car rental by using blockchain technology. In the future, car rental can be completed in three steps of "click, sign and open". The specific operation is: customers choose the car they want to rent, and then the transaction will be uploaded to the public account of the blockchain; Then, the customer signs a lease agreement and an insurance agreement from the driver's seat, and the blockchain will upload the information in real time. It is not hard to imagine that this leasing model may also be applied to the field of car sales and car registration
7. Network communication and Internet of things
IBM and Samsung are working together to realize an idea called adept. Adept uses blockchain technology to build the pillar of decentralized Internet of things. Coindesk said that with adept, the decentralized P2P automatic telemetry system, the blockchain can become a public system for many devices, and there is no need for a central hub to mediate the communication of various devices. After removing the central control system and identifying each other, the devices can automatically communicate with each other, manage software updates, bugs, or energy consumption
other companies are also committed to integrating blockchain technology into the Internet of things platform. For example, filamen, which uses blockchain technology to build a decentralized network for sensor communication, announced that they have obtained US $5 million investment in round a financing, with the participation of Verizon ventures and Samsung ventures
8. Smart contract
a smart contract is actually a computer program that functions on the action of another object. Like ordinary computer programs, intelligent contracts are also an "If then" function, but blockchain technology realizes the automatic filling of these "contracts" without human intervention. This kind of contract may eventually replace the core business of the legal instry, that is, the business of drafting and managing contracts in the commercial and civil fields
for example, mortgage loans can be completed through blockchain technology and automatically executed every year according to the terms of the contract. Ethereum, a crowdfunding platform based on blockchain technology, not only provides decentralized applications, but also provides smart contracts. Some users have married with their smart contracts. Another company, hedgy, received $1.2 million in seed round investment from Tim Draper, Marc Benioff, boost.vc and sand hill angels earlier this year. The company uses smart contracts to build a platform for users to discuss the value of bitcoin
9. Prediction
blockchain technology may shake the whole research, analysis, consulting and prediction instry. Aug, an online crowdfunding platform, hopes to make a profit in a decentralized forecasting platform. The company said it would offer a service that looked like a gaming swap. The whole process will be decentralized, and the AUG platform will not only provide users with sports and stock gambling services, but also provide election and natural disaster gambling services. This idea actually goes beyond sports gambling and creates a "forecasting market"
10. Online music
many musicians are choosing blockchain technology to improve the fairness of online music sharing. Billboard reports that two companies are automatically solving licensing problems by paying artists directly and using smart contracts. Peertracks, which is still in its infancy, wants to create a new music streaming platform where users can pay artists directly without middleman's intervention. Peertracks also hopes to create more direct interaction between artists and users
ujo music, led by entrepreneur Phil Barry, claims that they are rebuilding the music instry on the blockchain. Ujo also hopes to solve the problem of streaming music and artist payment. In addition to streaming music, it is also expected that ujo will be able to better classify the artists and creators behind the songs by using intelligent contracts as the autonomous brain of the song list
11. Travel sharing
Uber and other travel applications seem to be on the opposite side of decentralization. This company is like a deployment center, using its algorithm to control its drivers and their charges. According to the report of blog, Israeli venture LA & # 39; Zooz wants to "go against Uber.". The company invented its own patented digital currency, which, like bitcoin, can be digitally recorded using blockchain technology. Different from the centralized network, users can call in LA & # 39; Find people with similar itinerary on zooz, and then use LA & # 39; Zooz's currency pays the taxi fare. These coins can be used for car hailing in the future. Users can get LA & # 39 as long as they allow the app to track their location; Zooz's digital currency
12. Stock trading
for many years, companies have been trying to simplify the process of stock purchase, sales and trading. Emerging blockchain technology makers believe that they can go beyond the past, realize the automation of the whole process, and improve security and efficiency. Overstock's subsidiary T & # Com wants to use blockchain technology to realize online trading of stocks. Overstock is already using blockchain technology to issue public shares, wired reported. At the same time, chain, a blockchain technology maker (mentioned above), is working with NASDAQ to realize the share trading of private companies through blockchain technology.

5. Man, you're not technology, are you; There are too many. All kinds of ghosts and ghosts come to evaluate the blockchain. Often, these people's understanding of blockchain is just superficial, even nonsense. I used to learn a little bit about technology development, but later I was afraid of being bald and started working in the media instry, although I found that there was still a risk of being bald after I joined the instry
to get down to business, let me analyze the routine of media platform from the perspective of media. A company needs a certain public opinion environment when it needs to develop, especially in emerging instries. What kind of things will media do for emerging instries? They will publish false reports and even malicious remarks about the instry. It's often the work of small media companies, so why do they do it? It's very simple to earn traffic. The most eye-catching is often the heated comments. This kind of articles can easily incite netizens' emotions and increase their reading volume. In this way, the flow of cash is a very simple thing, then the capital of advertising will become higher. The more vertical reports the article has, the more valuable the vertical ads will be. For example, if I am a we media practitioner and I have been making untrue comments about the blockchain instry, then one day a blockchain company wants to send a report to me, then I can ask for a price
most of the untrue comments on the Internet can be divided into several categories: the spread of falsehoods between small websites and small media. Rumors start from taking out of context and making up, and then they will be further upgraded. The first wave of taking out of context and making up articles will be used to intercept part of the evidence to spread the upgraded version of rumors. When many stars or company leaders see this, their first reaction is: when did I say this&# 160; The second reaction is to laugh. The media, alas, is normal. More helpless, spend money to find the media to explain it, another group of people said you wash white. Don't make a statement and say you acquiesce. This vicious circle wave after wave, some companies are not so destroyed? In view of the above content, I give the questioner a clear way to distinguish, first: pay attention to check the level of the media that issued the article, and be happy with what the small media say, but don't take it seriously. Second: is it released from its official platform? If not, no one knows so much inside information
from the perspective of technology, what's wrong with blockchain technology? It's just an emerging technology. In fact, it can't be counted. It was first applied to bitcoin. It's just that there is a delay for the general public to come into contact with these, just as it will take a few years for the routine model of big cities to develop into small cities. Columbus cat does have a certain strength in the technical circle, and its technical reserves are quite sufficient. Just want to achieve comprehensive business development, it will certainly need a long march. For example, we may have developed the online payment system long before Taobao came out, but the technology can not be applied immediately. First of all, you have to convince others to believe you, so that you can really apply it. Father Ma succeeded in persuading Chinese women, so he succeeded. Blockchain itself is a cross era technology. To better promote it, more dedicated entrepreneurs need to work together.

6. 1. First of all, different brands and different series of procts have different characteristics and advantages. There are obvious differences in proct design, after-sales warranty service and many other aspects
2. It is recommended to select the motherboard suitable for indivials according to the actual use needs, use environment, actual budget, and proct comparison of physical stores or online stores
3. It is recommended to consult the local entity dealers or other major e-commerce websites about the description and specific price of the corresponding plate type, and make a comprehensive judgment and selection according to their own needs. As for which proct is better, there is no unified standard.

7. This is theoretical, that's why people ask questions about mining with galaxy, but it's hard to be true! The difficulty of mining will graally increase, and it will be found that the input and output are not very different.

8. Yesterday passed away silently with memory, today came quietly with hope, and tomorrow is shining for people. Some people are immersed in memories, they are attached to yesterday; Some people inlge in dreams, they look forward to tomorrow, these two kinds of people, forget that the most precious is today
today is a short day, isn't it? I will study hard from tomorrow. Today, isn't it just 24 hours? I'll start working hard tomorrow. Today is 1 / 365 of a year? My friend, why do you put what you want to do tomorrow and start from tomorrow? The sun and the moon are in a hurry. When tomorrow comes, tomorrow becomes today, and after every today there is an endless tomorrow. So, when will your determination and your ideal turn into action and reality
if farmers do not pull weeds, fertilize and kill insects in time today, how can they have a good harvest in the golden autumn? If the doctor does not rescue and treat the patients in time today, how can people be healthy in the future? If the cleaners don't clean the garbage in time today, how can the city be clean day after day? If the PLA soldiers are not fully armed and well prepared today, how can there be permanent peace for thousands of families
"tomorrow will be tomorrow, and there will be so many tomorrow; My life is waiting for tomorrow, and everything will be done in vain. "Just a few lines of poetry are the crystallization of the life experience of our ancestors after thousands of songs and hardships! The ancients had a sense of this, so they had the stories of "hanging the beam to stab the stock", "Ying Ying Ying snow" and "digging the wall to steal the light". Now that our conditions are superior, we should cherish today and seize every minute of it
to grasp today is to grasp the knowledge today; To seize today is to seize the possibility of invention and creation. Smart, diligent and ambitious people deeply understand that time is life, even more precious than life. They will never waste today's precious time on tomorrow. Edison, the great inventor, always cherished his time. He used his spare time to sell newspapers in the car to do experiments. When he was thirsty, he drank cold water; Hungry, chew a piece of bread; Sleepy, lying on the table to take a nap. Newton, Madame Curie, Einstein... This is true of all aspiring and successful people. They never inlge in wasting their time yesterday, destroying the light of life; Make efforts in time to open up the way of thinking. Friends, don't wallow in yesterday, don't wait and see tomorrow, everything starts from today! Today is the starting point of struggle!
