Runhe software has no blockchain

1. Shopping mall shopping mall shopping mall is still in the development stage, and now it is still young. Block chain mall also needs great technical strength and accumulation. Now the frontier is to develop more than a year's online shopping mall, which is also available soon after the official account.

2. 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.

3. Explain blockchain with scientific language --- blockchain is a permanent and irreversible modified record generated by superimposing encrypted data (blocks) in chronological order. Many financial institutions in the world, including JPMorgan Chase, HSBC, Citibank and New York Mellon bank, have also cooperated with blockchain companies to study the application of blockchain technology in the financial market. The person in charge of the blockchain Technology Laboratory of Shanghai Heshu software said that when there is no trusted third party in blockchain, all transaction data will be stored in a data block, and the transaction information will form a complete chain and be included in the blockchain, which is a more reliable ultimate solution than the trusted third party.

First of all, as a kind of underlying technology, blockchain landing is to combine the characteristics of blockchain technology with some fields, so as to give better play to blockchain technology to create greater value. I'll talk about it in detail

< H2 > the meaning of blockchain

in a narrow sense, blockchain is a kind of chain data structure composed of data blocks connected in sequence according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access A new distributed infrastructure and computing method of programming and operating data by using intelligent contract composed of automated script code, the data of the blockchain can not be tampered with, and can be combined with the e-commerce instry. Now there are a lot of fakes, combined with the technical characteristics of the blockchain. Every stage of goods from proction to shelf sales can be "data linked", so every stage of e-commerce can be transparent, which can greatly improve the safety of food<

NMC coin, also known as domain name coin, is a distributed domain name system based on bitcoin technology, with the characteristics of security and non censorship. There are no cheaters. However, e to the relative lack of supervision, digital currency is easy to be pulled up or sold, so it may become rich overnight, or it may lose all the principal overnight. This is the general nature of digital currency, not only NMC currency, but also the derivation and expansion of block chain technology

as a kind of underlying technology, blockchain plays a al role in this society. We must treat blockchain technology with a rational perspective, and we should not blindly trust others to invest, so as to avoid being deceived

5. 1. (1) if both wages and prices can rise in the same proportion, it really has no effect on those with wage income. But if someone does not have a salary, if they have a salary, but the wage increase is less than the price increase
(2) increased money can be released into the economy through bank credit channels, financial markets, etc. there is an objective necessary amount of money
but it is difficult to be constrained under the paper money system
(3) the central bank is the issuing institution of money. Of course, it is printed by the state. It is not certain who will benefit from inflation, such as whether you are a creditor or a debtor
(4) money is called the lubricant of economic wheel. If there is no money, commodity exchange is troublesome
2. The negative correlation between inflation and unemployment originated from the empirical study on the relationship between the change rate of British currency wage rate and unemployment rate by economist Phillips. After that, Samuelson and Solow verified the negative correlation between inflation and unemployment rate with American data, which became an important proposition in economics. However, there is a big debate among economists about whether this relationship holds.
