Blockchain discontinuity

1. I transfer bitcoin to you. Do I still have bitcoin in my hand
the fourth feature of blockchain assets is that they cannot be copied. The transmission of information on the Internet is . I sent a very interesting picture to fire coin Niuniu. The network copied the picture in my hand to Niuniu. It wasn't really taken away from me. I still have this picture in my mobile phone
right on the Internet has always been a big problem. Words, pictures and images are easy to , which brings great trouble to their right owners
the reason why blockchain assets can become assets is that they cannot be copied. It can be delivered through encryption rather than ing. When I send a block chain asset worth 1000 yuan to Niuniu, the 1000 yuan asset will be transferred from my account to Niuniu's account, and I no longer own the 1000 yuan asset. Non replicability is an important factor to ensure that it becomes an asset.
2. The information of each block in the blockchain is different, and the generation time and recorded data of each block are different. You can regard the blockchain as a bookkeeping book. Every once in a while, someone will write all the transaction information on the blockchain network to one page of the ledger, page by page, and record all the transactions on the blockchain network in turn according to the time
on the other hand, all nodes (computers in short) participating in the network will store one account book, which is updated in real time. Even if one node fails, the blockchain will not be affected.
3. At present, there are three application deployment types of blockchain: public chain, private chain and alliance chain. What's the difference between them? What are the typical applications<

public chain: open to all, anyone can participate

private chain: open to indivial indivials or entities

alliance chain: open to specific organizations
4. In the future, blockchain will be applied to all aspects through technology. For example, if someone needs to modify the content of an entry, this behavior will be recorded on the blockchain and cannot be eliminated. In addition, the network also released a totem, which is also a blockchain, and is mainly used in the field of pictures to protect intellectual property rights. In fact, there are many application directions of blockchain, such as court judgments, tickets, blockchain tax tickets and so on. This is the trend in the future. It is not advisable to issue virtual currency through blockchain to speculate in currency.
5. Bonus has been temporarily frozen, suspected MLM capital chain rupture, this is a very obvious sign<
the CBRC, the Ministry of instry and information technology, the people's Bank of China and the State Administration for Instry and Commerce suggest that in recent years, in the name of "financial mutual assistance", the behavior of promising high returns and luring the public to invest funds has appeared in many places in China. Its main characteristics include: 1
first, there are many names. Common are: "XX financial mutual aid community", "XX financial mutual aid platform", "XX financial mutual aid financing", "XX charity financial mutual aid platform", "XX financial mutual aid investment", "XX mutual aid community", "XX wealth mutual aid platform", etc< Second, it develops rapidly. Relying on the Internet, through the website, blog, wechat, QQ and other platforms, the publicity has a wide range
thirdly, it is confusing. Under the banner of "overseas celebrities", some claim to "destroy the unfair world financial system, break the control of financiers, and create a community for ordinary people" as the goal. Through the establishment of the so-called "fair, just, mutually beneficial and honest financial platform for people to help others", the public can get more help by subsidizing others. At the same time, he falsely claimed that "after market test, he has been mature in many countries for many years, and has hundreds of millions of members in the world" and so on
4. Strong incement. It claims that the investment threshold is low, the cycle is short and the income is high. For example, after free registration, the investment of RMB 60000-60000 can be withdrawn after 15 days, with daily income of 1%, monthly income of 30%, annual income of 23 times, and no handling charge. In addition, if participants develop others to join, they can also get extra income such as recommendation Award (10% of offline investment) and Management Award (the corresponding proportion is determined according to the membership level). There is no upper limit for development personnel and no upper limit for rebate< 5. Strong concealment. Most of them are controlled remotely by overseas personnel, and the investment funds are often transferred through personal bank accounts or through third-party payment platforms
this kind of operation mode violates the law of value, and it is difficult to maintain the capital operation for a long time. Once the capital chain breaks, investors will face serious losses. The general public is requested to raise their awareness of risks, invest rationally and prudently, and prevent their interests from being damaged. At the same time, we can actively report to the relevant departments the clues we have learned about crimes
bitcoin home and many mainstream media have reported similar virtual money pyramid schemes.
6. Detailed process of mining right price evaluation
1. Copy of the business license (plicate) of the mining enterprise of the evaluation client*
2. The of the mining license * or the approval document for delimiting the scope of the mining area, and the map of the mining area based on the topographic and geological map or geological map and demarcated by rectangular coordinates*
3. Reserve verification report, reserve review record certificate, *
4. Development and utilization scheme / (pre) feasibility study report / preliminary design and its review opinions or approval documents*
5. A complete set of financial statements for the three years before the base date of evaluation, at least providing the statistical table of output and sales price of mineral procts, sales revenue, cost of fixed assets and current assets and other major technical and economic indicators*
6. Basic information of the mine (including the nature of the enterprise, technical personnel, staff, registered capital, historical evolution, evolution of subordinate relationship, acquisition method, time and change of mining right, evaluation purpose and related process of mining right, proction and operation, etc.)
7. Information on the previous evaluation and price disposal of mining rights, including copies of previous evaluation reports, confirmation or filing documents of evaluation results, and documents on price disposal of mining rights (contracts or agreements and payment vouchers)
8. The plan of the nearest roadway project and the plan of reserves of the mine; 9. Copies of the annual mineral proct settlement sheet (main batch) or sales contract or sales invoice on the base date of evaluation
10. Traffic location map of the mining area, comprehensive geological and mineral plan (topographic and geological map indicating the scope of the mining area), reserve calculation map, typical profile of main ore body (exploration line profile), development system plan diagram and mining and beneficiation process flow chart
11. The mining volume of the mine from the deadline of reserves calculated in the geological exploration report / reserves verification report to the base date of evaluation. The appraisal of mineral rights can be divided into three stages, namely, the entrusted appraisal stage, the appraisal stage and the appraisal result confirmation or filing stage
first, the stage of entrusted evaluation. In this stage, the evaluation client and the evaluation institution are the leading ones< The appraisal client and the appraisal trustee can be people with different appraisal purposes, mainly including the administrative authority of the mining right that intends to transfer the mining right, the applicant of the mining right that intends to apply for registration of the mining right, the mining right that intends to transfer the mining right, the transferee of the mining right that intends to transfer the mining right, and the creditor when setting the mortgage of the mining right, Mining right holders who plan to restructure or go public. Generally speaking, anyone can entrust the appraisal of mining right, but if the appraisal result is used as the basis for collecting the price of mining right when the mining right is transferred, the administrative organ that transfers the mining right must be the appraisal principal; If it is necessary to apply for confirmation or filing for the purpose of transferring the mining right of the state funded exploration of the mining origin, the mining right owner must be the evaluation client. In short, there are only the right holders (the administrative organ of mining right transfer and the right holder) who have the right to dispose of the mining right of the proved ore procing area, so the evaluation must be entrusted by the right holders. In addition, it is their own right and choice for the relevant person to entrust to evaluate the mining right, but the follow-up procere will be different from the former
2. Entrustment and entrustment are service economic and legal relations established through the contract signed by both parties or the power of attorney issued by the client. When dealing with the entrusted matters, the client should explain the purpose, object, scope, ownership and investment nature of the entrusted appraisal. The appraisal institution should also explain the relevant provisions of mining right appraisal to the client, ask relevant questions and remind relevant matters. When both parties reach an agreement on the entrustment matters, they can sign the entrustment contract for mining right evaluation, or the entrustment party can issue the entrustment letter. The entrustment contract of mining right appraisal should comply with the general provisions of the contract law of the people's Republic of China. In the contract of entrustment for appraisal, the appraisal object, appraisal scope, appraisal purpose, required items, completion time, appraisal base date, rights, obligations and commitments of both parties, legal responsibilities, etc. shall be specified
Second, the evaluation stage is dominated by the evaluation institution. The main work of this stage is as follows:
(1) the mining right appraisal organization accepting the entrustment should form an appraisal working group to determine a mining right appraiser as the project leader, and the professional composition of the members of the appraisal working group should be suitable for the characteristics of the appraisal object and the appraisal method. The evaluation team went to the client's place for the following preparatory work: (1) listen to the client's detailed introction of the evaluation object, including the registration and change history of the evaluation object, the historical evolution of geological work, and understand the working time, working unit, nature of work, exploration results obtained, nature of investment, amount of investment, etc. It also includes the exploration and mining activities around the assessment object and the relationship with the assessment object 2) We will go to the scene to investigate the situation of mining rights, understand the topography and mining activities, sample some exploration projects, and inspect mining and mineral processing facilities 3) Investigate and collect the market transaction and market price of local mineral procts 4) Draw up evaluation ideas or technical routes and determine evaluation methods. Collect documents, data and drawings related to the assessment 5) Summarize and sort out the data
(2) the appraisers shall exchange opinions with the client on the first draft of the appraisal report and make necessary adjustments, modifications or supplements. After the final draft, submit the formal evaluation report to the client. The necessary information provided by the client includes: assignment evaluation: the area and geographical coordinates of the exploration area or the opinion on delimiting the mining area; Transfer evaluation: exploration license, or mining license, the supporting documents that can explain the nature of exploration investment; Geological reports and maps of each stage; Relevant documents proving the resources / reserves within the scope of exploration license or mining license; Mine enterprise registration, statistics and reported reserves change report. The main data collected by the appraisal institution include: the development and utilization plan of mineral resources or (pre) feasibility study report or preliminary design and relevant approval documents; Mineral processing process and proct plan; Statistical report of actual indicators such as mining recovery rate, ore dilution rate, beneficiation recovery rate, concentrate yield, etc; Statistical report on recovery of associated and symbiotic ores, etc< According to the three regulations of the State Council on the management of mining rights and the provisions of relevant documents of the State Council, the appraisal results of the mining rights formed by state funded exploration, whether the appraisal is transfer or transfer, must be confirmed or filed by the Department in charge of Geology and mineral resources of the State Council. Therefore, the confirmation and filing stage of the evaluation results only corresponds to the broken property rights formed by the state funded exploration; It is a necessary procere and is evaluated by the obligee as the client. In addition, according to the Interim Provisions of the Ministry of land and resources on the administration of the transfer of mining rights, no matter what the nature of the original investment is, the administrative organs of mining rights need to evaluate and confirm or record the evaluation results< (1) the three regulations of the State Council on the management of mining rights have explicitly authorized the Department in charge of Geology and mineral resources of the State Council to confirm the evaluation results of mining rights funded by the state, that is, the Ministry of land and resources. The confirmation of mining right evaluation results can be divided into two forms: direct confirmation by the Ministry of land and resources and entrusted confirmation. The Ministry of land and resources confirmed that the mining right issued by the Ministry of land and resources, the mining right stocks listed, and the proction scale of large and medium-sized enterprises transferred in the form of bidding. Entrustment confirmation: other mining right appraisal and confirmation work other than that confirmed by the Ministry of land and resources shall be entrusted to the mining right administrative organs of all provinces, autonomous regions and municipalities directly under the central government. After confirmation, the mining right administrative organs of all provinces, autonomous regions and municipalities directly under the central government shall fill in the letter of responsibility and submit it to the Ministry of land and resources together with the appraisal report. The Ministry of land and resources shall uniformly number, seal and issue the confirmation letter
(2) according to the three regulations of the State Council on the management of mining rights and the relevant documents of the State Council, the evaluation results of the mining rights formed by state funded exploration, whether it is transfer evaluation or transfer evaluation, must be filed by the Department in charge of Geology and mineral resources of the State Council
1. The Ministry of land and resources records the evaluation report of exploration rights according to the proceres of verification, filing and filing
1) according to Article 14 of the Interim Measures for the administration of the evaluation of exploration rights and mining rights and the requirements of the guidelines for the evaluation of mining rights on the format of the evaluation report of mining rights, the staff responsible for the verification and filing of the evaluation report of exploration rights shall carry out the verification. The specific verification contents include: (1) whether the evaluation report is within the scope of filing. The appraisal report of mineral exploration right transfer within the scope of filing must be: the appraisal is entrusted by the organ of mineral exploration right transfer (the valid certificate is the appraisal power of attorney of the organ of mineral exploration right transfer or the appraisal power of attorney contract of both parties); The appraisal object is the mineral land that has been invested and explored by the state (according to the announcement of the Ministry of land and resources on the mineral land that has been invested and explored by the state). The nature of exploration funds is contributed by the State Finance (Geological Exploration fee, resource compensation fee and special fund) The effective proof document is the mission statement of exploration project. For the newly registered exploration right after the State Council Order No. 240 was issued in 1998, whether the price of exploration right was charged or not at the time of transfer depends on the nature of the exploration fund after this registration, and whether it is within the scope of filing or not, rather than retrospecting the nature of the investment of exploration work before registration. For the exploration rights acquired before February 12, 1998 and extended up to now, it depends on the nature of exploration funds in the whole exploration history.) 2) (3) check whether the format and attachments of the evaluation report are complete and standardized. Whether the evaluation object is an effective exploration right. No problem is found in the above verification, and the next procere will be carried out. In case of any problems found in the above verification, the applicant for record shall be informed in writing, and the evaluation report shall be returned to the applicant for record. The filing applicant shall apply for filing again after solving the problem. If the re verification has met the requirements, enter the next procere
2) the staff responsible for the filing of the evaluation report of exploration right will submit the verified evaluation report together with the approval form for the filing of the evaluation result of exploration right to the director, who will make a decision on whether to approve the filing after review. If the record is approved, the "record verification certificate of prospecting right evaluation report" shall be issued to the record applicant. If the record is not approved, the reasons shall be explained to the applicant in writing, and the evaluation report and relevant documents shall be returned
3) filing: the evaluation reports approved for filing are registered and filed for future reference
2. Evaluation of exploration rights other than those recorded by the Ministry of Geology and mineral resources of provinces, autonomous regions and municipalities directly under the central government.
7. 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.
8. Blockchain "chain" everywhere? Not all fields can achieve the popularity of "blockchain"
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.
