Will blockchain cause waste

1. No
although the currency circle is in a bear market, blockchain is not useless without cryptocurrency
the blockchain instry has developed rapidly in recent years, and more and more blockchain technologies appear in front of people. More and more blockchain applications are landing, blockchain e-invoice, blockchain traceability, blockchain finance and so on. Talents in the blockchain instry are also very scarce. Many colleges and universities in China have set up blockchain courses to provide talents for the blockchain instry
the development of a new technology will inevitably encounter setbacks, and the blockchain instry will grow stronger in the future.
2. Blockchain technology will not affect efficiency and waste computing power. The key is to see how to innovate in a mode and how to use blockchain technology efficiently to achieve the effect of the mode
blockchain is essentially an encryption algorithm, which is based on the principle of hash 256 bit algorithm to achieve information security; The application of modern information will become more and more global and universal. Besides the basic requirements of anti tampering, anti repudiation and trustworthiness, the protection of privacy needs to be strengthened. The blockchain technology is proced because of the development of modern cryptography. The cryptography used today is the result of cryptography 20 years ago, Therefore, in order to apply the blockchain technology to more participation scenarios, especially in the Internet economy, more verification is needed to verify whether the existing encryption technology can meet the demand, and more in-depth integration of cryptographic frontier technology and continuous innovation are needed
as long as we use blockchain to make innovations in accounting methods based on our own mode, it will not affect efficiency and waste computing power, but will shorten the time and improve efficiency.
3. Blockchain is a technical solution to collectively maintain a reliable database through centralization and distrust. This technical solution allows any number of nodes in the participating system to calculate and record all the information exchange data in the system in a period of time to a data block through cryptography algorithm, and generate the fingerprint of the data block for linking the next data block and checking. All participating nodes in the system jointly determine whether the record is true
blockchain can improve the way of data recording in audit. In the current network audit, although there is an early warning mechanism, it still needs auditors to judge and handle the abnormal records manually; Blockchain can automatically process the abnormal records through whether each node verifies and approves the block and the transaction information in it, whether the network node is attacked, and whether the account book of each node is complete, so as to make real-time audit possible. Auditors can directly access and query the effective information on the blockchain, judge whether the processing is reasonable and make corrections. In the blockchain, timestamps are used to record various transactions and operations, which can achieve historical traceability and tracking, and greatly improve the quality and efficiency of audit
blockchain can change the storage mode of audit data. In traditional audit, data are stored in an audit center server, which not only has the problems of high load and slow running speed, but also is vulnerable to attack; The blockchain audit system is a typical distributed storage, each node has the same backup, which can not only save the high cost and maintenance costs of the server, but also ensure the integrity of the data
semi public private chain can be used for audit. Blockchain can be divided into three forms: public chain, semi open private chain and full private chain. Considering the characteristics of audit instry, it is appropriate to adopt semi open private chain mode. For the audited units and enterprises, some trade secret information is not disclosed, but the pre selected nodes within the group decide the generation of the block. External suppliers can participate in the transaction but not the accounting process. Externally, it provides a third-party query node to query through the open API. In this way, it can not only ensure the internal privacy of the enterprise, but also enable the external auditors to implement real-time audit query.
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. Hello, of course.
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block. In fact, the original English version of bitcoin white paper [1] does not use the word blockchain, but uses the word chain of blocks. In the earliest Chinese translation of bitcoin white paper [2], chain of blocks was translated into blockchain. This is the earliest time when the Chinese word "blockchain" appeared.
6. Qihuan not only provides power exchange, but also provides maintenance services. Qihuan app uses blockchain technology to track the data of trams, batteries and power exchange cabinets to provide services!
7. What platform is this? Click recharge generated after the two-dimensional code is the recharge address, you transfer your digital currency to change the address can recharge success.
8. With the combination of 5g and robot technology, new consumer electronics procts are emerging. AI solves the problem of machine understanding the world and human-computer interaction. 5g expands the mobile boundary of the robot, and provides more computing power and storage space for the robot (cloud cooperative robot)< According to the IFR classification method, robots can be roughly divided into instrial robots and service robots. Traditional instrial robots are mainly used in automobile and parts, electronic manufacturing, metal and machinery, food processing and so on. Its main feature is to complete the specified action along the specified path according to the predetermined procere. How can AI / 5G enable robots

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

pencil recommendation:

after two years of rapid development in 2017 and 2018, the number and amount of financing in the artificial intelligence instry will show a precipice like decline in 2019, capital will be concentrated in the head enterprises one after another, and small companies will have a hard time surviving. 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

I. foreword

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.
9. 1、 Property law is the gospel of property owners

Article 12 of the constitution of the people's Republic of China stipulates that "socialist public property is sacred and inviolable", "no organization or indivial is allowed to occupy or damage state and collective property by any means", and Article 13 stipulates that "citizens' legitimate private property is inviolable", "The state protects citizens' private property rights and inheritance rights in accordance with the law.". The second paragraph of Article 73 of the general principles of civil law stipulates that "state property is sacred and inviolable" Article 4 of the property law stipulates: "the property rights of the state, the collective, the private and other right holders shall be protected by law and shall not be infringed by any unit or indivial." It can be seen that the equal protection of public property and private property in the property law actually improves the relative legal status of private property and establishes the principle that private property and public property have the same civil status, which lays the foundation for the legal restoration of the universal equal civil relationship between state-owned and non-state-owned property rights, Moreover, combined with the fact that the income and wealth of Chinese citizens have generally increased since the reform and opening up, the "property owners" protected by the property law have covered the actual interests of the vast majority of the Chinese people< Second, the property law is about the legal appreciation of RMB.


in the legislative explanation and deliberation report, the property law has made positive explanations or provisions on the right to contracted management of rural land, the right to use homestead, the right to use urban commercial residential land and other major property rights involving the vital interests of the masses, It fully reflects the principle of respect and retroactive protection for citizens' real right in fact. For example, Article 149 of the property law stipulates: "if the term of the right to use residential construction land expires, it will be automatically renewed." This is not only a supplement and improvement to the unreasonable legal provisions in the past from the perspective of social stability, but also a concrete manifestation of respecting citizens' factual rights to "things" -- the vital interests of the overwhelming majority of the people are the most important social public interests, and the law, as a form of protection, should only adapt to it rather than become a system shackle, The legislative practice of property law vividly implements the basic principles of "seeking truth from facts", "respecting facts" and "people-oriented". In terms of "automatic renewal of the right to use residential construction land" only, the property law dispels the huge interest ambiguity and injects huge future economic expectations for the real estate instry, which occupies an important proportion in the national economy. In other words, through the property law, the real estate instry has the right to use residential construction land, After the expiration of the term of the right to use residential construction land, the huge rights and interests of the state owned by the original provisions are clearly retained by the original property owner according to the fact of possession of the "property", which is actually a huge, clear and legally guaranteed social investment for the real estate economy through legislation. From the above point of view, the property law opens up the operation space for the legal appreciation of the important social universal property rights, which is not only beneficial to the asset appreciation of the related instries and fields involved in the rural land contractual management right, the right to use homestead, the right to use urban commercial residential land, but also a legal appreciation of RMB< Thirdly, the economic significance of the property law is underestimated by the society.

at present, we need to further study the economic significance of the property law and look for the significant impact of the implementation of the property law on the real estate economy, financial economy and rural economy. We must pay attention to that this is an objective fact, What's more, it is an important effect that will continue to play a role in the future, or it is a far-reaching event that touches all fields of China's social and economic life. A realistic suggestion is that it is necessary for the economic instry and the general market people to explore the strategic influence from the property law in combination with their own reality, so as to obtain specific and practical strategic enlightenment
10. Seven misunderstandings about blockchain
blockchain based systems have broad prospects in the future, but we need to be very clear about what blockchain can do. Imagine the blockchain technology in the next 20 years, its impact may be as big as the Internet
however, it is shocking that we mainly see today that the project seems to be based on decentralized design, but in fact there are some misconceptions about blockchain
if we want technology to continue to move in the right direction, we need to turn this craze into proctive and realistic expectations, so as to rece the possibility of the supply chain falling to the bottom. Once it falls to the bottom, it may be abandoned in the corner with meaningless proof of concept
let's take a look at the seven misconceptions of unrealistic expectations for blockchain:
misconception 1: highly scalable
compared with traditional (server based) trading methods, blockchain deployment does not have real scalability, and the current trading time depends on the slow party. They are only scalable for certain types of transactions, such as transactions with small payloads and transactions close to certain limits. You can't just pile up information on the blockchain
Myth 2: it is absolutely secure
although the blockchain is based on encryption standards, the method to ensure privacy is completely outside any blockchain standards and implementation. Only encryption experts can really understand and verify blockchain integration. However, each implementer has the responsibility to ensure security, so this approach is largely the same as the management of financial transactions in the old era
mistake 3: trustworthy
the blockchain ensures the integrity of transactions and information, otherwise anything stored in the blockchain cannot be trusted. You need to make sure that the parties that store the facts in the blockchain are trustworthy and that the facts are true to determine that they are truly trustworthy. This governance model allows multiple parties to be jointly and severally liable for the infrastructure, and requires secure access to store facts in the blockchain
myth 4: you can put anything in the blockchain
blockchain is a protocol represented by code, which is not defined according to any standard. There is no standard body to provide rules or guidance for the implementation of sanctions
generally, you can only handle small payloads, and you still need to reach an agreed standard among all participants so that anyone can understand what is stored
myth 5: you can express anything in a smart contract
although this is technically feasible, in practice, blockchain is limited to simple and easy to understand use cases. Smart contracts are very complex in nature. By design, once released, you cannot modify or repair them. They contain very complex interactions and irreversible results
myth 6: if you don't like public chain, please choose private chain
private chain is not a channel to obtain privacy or access restricted information. In fact, you can even think that private chain should not be an open option. Nevertheless, enterprise blockchains may not be able to realize any inherent advantages of blockchain technology, and privately developed blockchains may lack the community and academic review necessary to ensure their attributes
myth 7: the size of the community doesn't matter
the blockchain procts promoted by the community are being forked by private players in all aspects, and they strengthen their role in various ways. However, a large community composed of users, users, scholars and implementers is the only force to ensure the validity of password attributes. Only the open source blockchain with the largest community and installation base will last. The rest can be regarded as experiments in the laboratory, of which 99.9% will die
a smart technician will move forward based on use cases and a set of first principles in his mind. First, there may never be a blockchain to manage all of them. Two different use cases require different blockchains. Some participants are many, some are few, some need strong privacy around facts, and some are fully transparent
considering all the above, what we can do together now is to innovate, tackle real business problems, and initiate and promote proof of concept to better understand the power of blockchain.
