Industrial brain blockchain

1. 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.

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.

2. The core of blockchain lies in consensus. Successful blockchain projects need to be recognized by more people. Therefore, the development of blockchain ultimately benefits the people, and the real significance of blockchain technology is to make people live more conveniently and simply. Hangzhou shimai Technology Co., Ltd. is such an innovative company, which applies blockchain technology in practice and benefits the general public.

3. This year, 47, nearly 50, the average daily programming time is six to eight hours. I'm not as fit as young people. When I was 30 years old, I could program for more than 20 hours in a row. People often see me in the company on the first day of work and I'm still in the company on the second day. Older, obviously easy to fatigue, work to two after, also can't write anything. Once the physical condition is also very poor, allergic rhinitis, cervical spondylosis, scapulohumeral periarthritis, periodic upset stomach and so on. Last year, I began to go to the gym and see a rehabilitation doctor for posture correction. After a few months, these problems were obviously improved, rhinitis was basically controlled, cervical spondylosis was no longer committed, and occasionally discomfort could be quickly adjusted by oneself.

4. Why digital transformation? The reasons are as follows:
1
2
3. The homogenization of enterprise's goods and services is becoming more and more serious, and the difficulty of innovation and technological breakthrough is becoming more and more difficult
4. With the transparency of information, the demand of users is more and more demanding, and the demand for personalization is higher and higher. Enterprise data upgrading can make enterprises accurately understand the needs of users, provide customized services for users, and retain users. At the same time, digitization can help enterprises optimize decision-making and improve resource allocation. It plays a significant role in recing costs and improving competitiveness
digital transformation is an arous challenge, but successful transformation can bring immeasurable value to enterprises. Now the world economy is in a period of great transformation from instrial economy to digital economy. Our country's enterprises have their advantages, such as huge talent pool, complete instrial system and complete Internet ecosystem. However, there are also some challenges, such as weak foundation, insufficient innovation and rigid organization and management. How to make full use of advantages and avoid disadvantages, and realize the smooth transformation and upgrading of enterprises, also need the cooperation between enterprises
information digitization generally includes three stages: sampling, quantization and coding
sampling
the function of sampling is to sample the continuous analog signal according to a certain frequency to obtain a series of finite discrete values. The higher the sampling frequency is, the more discrete values are obtained and the closer the original analog signal is<
quantization
the function of quantization is to divide the range of sample values after sampling into a limited number of segments, and to represent all sample values falling into a certain segment with the same value. It is a mapping operation that uses a finite discrete numerical quantity to replace an infinite continuous analog quantity. The higher the quantization number is, the more precise the sample size is
coding
the function of coding is to convert discrete numerical values into binary codes, that is, digital signals, according to certain rules
sometimes the digital process also includes data compression.
