① In the era of digital economy, innovative application scenarios of blockchain continue to expand
In the era of digital economy, blockchain, as a new driving force for economic growth, is leading a new round of global technology Revolution and industrial change. At present, blockchain is developing rapidly and penetrating into all areas of our country's economy, which not only strengthens the resource allocation capabilities of the digital economy, but is also of great significance for promoting high-quality economic development and improving the modernization of the national governance system and governance capabilities.
Blockchain is the new engine driving digital development
As the role of blockchain in the digital economy grows, its innovative applications continue to expand. According to the "China Mobile Internet Development Report (2021)", "There were nearly 2,000 blockchain projects across the country last year, and the blockchain market size exceeded 3.2 billion yuan."
China Academy of Information and Communications Technology Industrial Internet and Liu Yang, deputy chief engineer of the Internet of Things Research Institute, once said that blockchain is a trust infrastructure necessary for the development of economic activities. It provides inclusive public services for finance, agriculture, industry, energy and other industries and the public. It is also a Collaboration tools, transforming production relations, and integrating with the real economy will improve collaboration efficiency and reduce costs.
In fact, blockchain is called "the next generation of Internet-level technology" because of its disruptive innovation, and is considered the most revolutionary among strategic emerging technologies. In October 2019, blockchain was elevated to a national strategic level. In April 2020, blockchain was included in the new infrastructure and was listed as one of the seven "key digital economy industries" in the "14th Five-Year Plan". In the future, blockchain will usher in new opportunities for innovation and development.
However, Zhang Chao said that currently, data governance on the blockchain is still a huge challenge at a global level. First, data governance requires a clear regulatory subject, but in blockchains or distributed ledgers (or public chains) other than alliance chains, a relatively clear object may not be found as a regulatory subject; secondly, due to the The data on the chain cannot be easily tampered with, which means that during the data governance process, the rights of the data owner to modify and delete the data may not be fully protected.
Blockchain innovative application scenarios continue to expand
Driven by favorable policies and market demand, blockchain innovative application scenarios continue to expand. In recent years, in addition to the two major outbreak scenarios of finance and government affairs, there is even more promise in empowering the field of rule of law. On the one hand, the multi-faceted and multi-field application of "blockchain + rule of law" can effectively improve the efficiency of rule of law construction; on the other hand, blockchain technology can also help public prosecutors and law enforcement agencies crack new criminal cases.
Industry insiders believe that based on the analysis and tracking of massive on-chain data, blockchain technology provides governments, enterprises and users with on-chain data monitoring, transaction maps and on-chain addresses.analyze. For suspected criminal activities such as virtual currency, the blockchain browser provides on-chain data tracking to combat virtual currency crimes, safeguard national financial security, and provide "blockchain power" for the construction of Digital China.
② Why is Bitcoin rising now?
Because it has fallen too much. There is no one that can only fall but not rise or only rise but not fall. It is like a cycle. At a certain stage, it will will be reversed.
③ What exactly can blockchain bring to us
I don’t quite understand this. After all, I’m only a student and haven’t had a deep understanding of this aspect. If you If you want to know, you can check online. It will be good for you to learn more.
④ Blockchain technology and applications: a technological revolution in the future
Blockchain technology originated from "Bitcoin: A Peer-to-Peer Electronic Cash System" proposed by Satoshi Nakamoto 》, where "block" means that each information block contains a timestamp. Information blocks containing timestamps are connected to each other, and the chain of information blocks formed is a "blockchain".
Blockchain is a technical solution that collectively maintains a reliable database in a decentralized and trustless manner. From a data perspective, blockchain is a distributed database in which a single node or multiple nodes cannot intentionally change data records. Its distribution is reflected in the distributed storage and distributed recording of data. From a technical perspective, blockchain technology is an emerging technological achievement resulting from the integration of multiple technologies. After the development and improvement of a combination of multiple technologies, it forms a more efficient way of recording, storing and expressing data.

⑤ Learn from the Chinese version of the "Messi Conference", can foodies in mainland China become real gold?
< br />
“Macy Conference”
“Macy Conference” may not be It is well known to the public, but in the eyes of academic circles, this is a meeting of great significance in the history of science, known as the "Pioneer Conference of the Third Scientific and Technological Revolution". It is in the regularly held "Massey Conferences" that mathematicians, physicists, sociologists, and semanticists from all over the world have conducted interdisciplinary discussions and cooperation, providing the basis for almost all scientific research in the second half of the twentieth century to the present. Major scientific and technological issues have laid the foundation.
"We are in an era of technological explosion, and human society is gradually approaching the 'technological singularity.'" Inspired by the mission of the times, the famous economist Zhu Jiaming led his Digital Asset Research Institute on December 17 -1On the 8th, the Chinese version of the "Messi Conference" - the Blockchain Mathematical Science Conference was hosted in Beijing. The conference focuses on exploring and dismantling existing blockchain mathematics paradigms, looking for mathematical fields related to blockchain technology, and combining mathematical tools that can introduce blockchain technology.
As a practical application of blockchain in the catering industry, foodie mainland The product uses a set of algorithm mechanisms based on the "incentive compatibility" theory of game theory to mobilize the enthusiasm of all participants to build an ecosystem. Although this algorithm mechanism has been initially verified, in order to make the theoretical foundation more solid, we have been looking for deeper internal scientific principles.
With admiration for science and the desire for "the most perfect mechanism algorithm in the world", the Chihuahua Continental team studied this area extremely seriously. Blockchain Mathematical Sciences Conference.

Can AlphaGo surpass humans? Scientist Zhang Bo said that computers are far behind humans...
Zhang Bo, academician of the Chinese Academy of Sciences
< p>The in-depth analysis of artificial intelligence by Zhang Bo, a computational scientist and academician of the Chinese Academy of Sciences, seems to allow us to see a little bit of the value of "being born as a human being".
Zhang Bo pointed out: "The reason why AlphaGo and Deep Blue can succeed is because chess is a complete information game. If it is complete information, it is It is extremely easy and will definitely surpass humans. Therefore, in Go and chess, machines will eventually surpass humans. It is only a matter of time.
But if It becomes incomplete information, such as playing cards. Now, whether it is four-player bridge or four-player mahjong, computers are no match for humans at all. The reason is incomplete information. The same is true for decision-making. If your decision-making It is complete information decision-making, and machines will definitely surpass humans. But if you are making decisions with incomplete information, then computers are still far behind humans. But unfortunately, all decision-making scenarios involve incomplete information, and actual decision-making scenarios are It’s human.”
As a senior catering project, Chihuahua Mainland has industry information advantages. No matter how powerful the algorithm is, if you don’t know the productionThe industry’s real cost operation information cannot dismantle the correct gaming strategy. Based on this understanding, the Chihuahua Continental team is quite pleased that the algorithm we designed is at least operable.
But we are still not satisfied, we long for ourselves to be better!

Only mathematicians can do mathematics? Economist Zhu Jiaming emphasizes the value of professionals in application fields
Zhu Jiaming, President of the Digital Asset Research Institute
< /p>
Professor Zhu Jiaming pointed out at the beginning that mathematics gave birth to blockchain. From a development perspective, Professor Zhu Jiaming also said that blockchain has the possibility to extend into branches of applied mathematics. But academic discussions have always been cutting-edge. When it comes to practice, Professor Zhu also admitted: "At this moment, it is difficult to draw a conclusion on which new mathematical tools can be effectively combined with the blockchain."
Mathematicians are not the only ones who can develop blockchain applied mathematics. Historically, there are many precedents for professionals in applied fields to enter the field of mathematics.
Professor Zhu Jiaming gave an example: "For example, physicists, aerospace engineers, geologists, biologists, and economists have encountered practical problems. , input mathematical tools into their research fields, or invent some new mathematical methods.
Here is one that seems far away from us but is inspiring An example of this is the combination of biology and mathematics. The combination of the two produces mathematical biology and biomathematics. These are two scenarios where mathematics and biology are combined.
The difference between mathematical biology and biomathematics is that mathematical biology uses mathematical methods to study biological problems, while biomathematics uses mathematical problems in biology to form new mathematical methods."
< p>It can be seen that the path of exploring blockchain applied mathematics also requires the efforts of industry professionals. Encouraged by Professor Zhu Jiaming, Chihuahua Mainland, as an explorer of the catering blockchain industry, finally found another historical mission to improve itself - to explore mathematical methods for catering blockchain applications.

Young enough Fearless, Wang Feiyue, an expert from the Chinese Academy of Sciences, tells you how invincible human imagination is...
Chinese Academy of Sciences Complex System Management and Control Wang Feiyue, Director of the State Key Laboratory
He is fearless because of his youth. This excited little heart has not yet been calmed down. Teacher Wang Feiyue’s views on imagination are amazing. Makes us want to go against the grain.
Wang Feiyue, director of the State Key Laboratory of Complex System Management and Control, Chinese Academy of Sciences, vividly gave us a walk through the history of science. When it came to artificial intelligence, he quoted Tao Te Ching.
He said: "Intelligence is divided into three levels. One is algorithmic intelligence, which is our artificial intelligence. It can be written into a program, but it is far smaller than language intelligence. , and the intelligence that human language can express is far smaller than the intelligence we imagined. This is consistent with the Tao in the Tao Te Ching. Later, archaeologists discovered that, alas, these are not two sentences. , should be three sentences, Tao, Tao, very Tao, which corresponds to these three levels."
The Chihuahua Mainland team deeply agrees, We have always had a consensus that under the myth of technology, it is as if there are no people in the world except machines. This is obviously not the case. Several experts at the meeting also pointed out that imagination is the reason why humans will never be surpassed by machines.
In an era when computational intelligence can already perform "self-learning" through "raw data input", the more important role of human beings is to: transcend perception and discover patterns.
According to the requirements of the conference organizer, all experts at this conference need to propose their own "blocks" Chain Mathematical Conjecture”. Many conjectures are very interesting, such as the “small-scale consensus is vulnerable to attack” and the “two-military problem” proposed by Yuan Yong of the Chinese Academy of Sciences. From an industrial point of view, although these conjectures are relatively metaphysical, they are good thinking training.
It’s exciting when we see new practice-based approaches in the industry. For example, Mr. Jia Ke proposed the "two high characteristics of smart contracts": "too many restrictions and high difficulty" and "can be triggered internally and high risk". through realityThrough empirical observation, they found that blockchain can completely abandon "smart contracts", "the functions and implementation logic required for blockchain applications can be triggered externally", "self-certifying storage mechanisms" and other phenomena. Based on these methods, complex Internet applications without central servers can be developed.
Associate Professor Ding Xiaowei of Nanjing University’s new attempt at financial derivatives also allows us to see the new power of blockchain in reconstructing financial mathematics.
At this conference, we clearly saw that basic theory is the cornerstone of industrial development, and industrial development is the significance of basic theory. Foodie China is changing the catering industry for the better. This is the best result of basic theories such as blockchain mathematics.
⑥ How to get it right Looking at blockchain technology
From a technical perspective, blockchain is likely to be a major technological revolution after the Internet. Currently, major corporate giants around the world are working hard on the research and application of blockchain technology. SAP opened a pilot version of the blockchain project in May last year. Banks in Japan and South Korea have just begun testing blockchain technology. Tencent has registered the trademarks "Ether Lock" and "Tencent Ether Lock". In April 2017, Tencent released the "Blockchain Solution White Paper" and announced that Tencent's blockchain industry solutions with independent intellectual property rights were officially released on the official website. The network launched the blockchain open platform "BaaS", which is a project based on blockchain technology independently developed by the network. It mainly helps enterprise alliances build their own blockchain network platforms.
Xu Weihong, chief economist of AVIC Securities, believes that the concept of blockchain has been proposed for a long time. This round of being touted by speculators in the A-share secondary market originated from Bitcoin. Hype on a global scale. Participants do not care about the technical value of the blockchain, but they care about how much profit and water they can get from the existing "seigniorage" by creating digital currency through the blockchain. Some institutional investors even hope to use their professional judgment and ability to control market sentiment to "cut leeks" from the large amount of blind influx of social funds. In view of the recent rise of the blockchain concept, all parties concerned must remain sober. Financial exchanges and intermediaries must stay awake and reduce unnecessary advertising to mislead small and medium-sized investors, and ordinary people must also stay awake.
