❶ With 1,400 crypto companies such as Binance and Huobi settling in, what is Dubai’s attraction?

Cailian News Agency | Blockchain Daily (Hangzhou, reporter Xu Cihao) , Recently, Saudi Arabia announced that it will invest US$6.4 billion in the Metaverse and blockchain technology.

In fact, the United Arab Emirates, also a major oil country, has always been one of the countries in the world that supports and embraces blockchain the most, and Dubai in the United Arab Emirates has become one of the gathering places for blockchain companies.

According to local news reports in the UAE, the digital economy contributed a total of approximately 100 billion dirhams ($27.25 billion) in 2021, accounting for 4.3% of the UAE’s GDP. The country is home to more than 1,400 blockchain and crypto startups with a combined valuation of AED 90 billion ($24.5 billion). More than 90 investment funds and 12 business incubators are also supporting the country's digital industry, according to government data.

Industry insiders analyzed to the reporter of "Blockchain Daily" that blockchain, as a new technology, is treated differently in different parts of the world; and Dubai has attracted global blockchain companies through its open policy. and talents, taking the lead in the future development of the blockchain industry.

1,400 crypto companies have settled in

The United Arab Emirates, referred to as "UAE", is a country consisting of Abu Dhabi, Dubai, Sharjah, Fujairah, Umm Al Quwain, A federal state composed of seven emirates, Ajman and Ras Al Khaimah. The United Arab Emirates is known as the flower in the desert due to its rich oil production.

But oil countries also have a sense of crisis, that is - oil resources are not inexhaustible, and the flowers in the desert will wither. They must find new opportunities for wealth.

The blockchain and encryption industries represented by Bitcoin have given some small countries, including the United Arab Emirates, Saudi Arabia, and El Salvador, new vitality.

Dubai, in the United Arab Emirates, is on its way to becoming a Bitcoin trading center. Binance, ALPEX, Metahero and hundreds of companies (including more than 90 investment funds and 12 business incubators) have chosen Dubai as their operation center.

In 2021, China has launched a round of rectification of virtual currency mining and trading. Many Chinese blockchain and crypto-asset companies have also moved to Dubai to seek compliance operations there. These include Huobi Exchange, Hufu Exchange, coinw Exchange, etc., which have completed the withdrawal of users in mainland China by the end of 2021.

A reporter from "Blockchain Daily" learned from relevant sources in Huobi that Huobi currently has an office in Dubai, which has domestic employees and local employees.

"Dubai has always been very active in its policies towards blockchain companies." The above-mentioned Huobi official told reporters.

In addition, on December 20, 2021,Cryptocurrency exchange Binance has signed a cooperation agreement with the Dubai World Trade Center Authority (DWTCA) to jointly promote the establishment of a new international crypto-asset ecosystem in Dubai.

An anonymous exchange insider told the "Blockchain Daily" reporter that in view of Dubai's current open policy for exchanges, they are also actively seeking Dubai's virtual asset trading license. The timing Operations will be moved there when mature.

Due to the UAE’s open policy towards cryptocurrency, it has attracted many companies to settle here. According to local news reports in the UAE, the digital economy contributed a total of approximately 100 billion dirhams ($27.25 billion) in 2021, accounting for 4.3% of the UAE’s GDP. The country is home to more than 1,400 blockchain or crypto startups with a total valuation of AED 90 billion ($24.5 billion).

Dubai's open policy

"Blockchain Daily" reporter learned that the supervision of Dubai's cryptocurrency is governed by FRSA (Financial Services Regulatory Authority), SCA (UAE Securities and Commodities Authority) ) and DFSA (Dubai Financial Services Authority) completed.

In order to provide encryption services in the UAE or Dubai, a license is required from the SCA or FRSA (depending on the location of operations). Trading of cryptocurrencies is regulated by the SCA and FRSA, and licenses may be granted depending on the cryptocurrency nature of the transaction.

At the end of 2020, the UAE Securities and Commodities Authority (SCA) issued the "Decision No. (21/RM) of 2020 of the Chairman of the Authority on the Regulation of Crypto-Assets".

The regulation aims to establish a clear licensing regime for any provider wishing to provide crypto-asset services in the UAE. This includes initial token issuances, exchanges, marketplaces, crowdfunding services based on or utilizing crypto-assets. financing platform, custody services and related financial services.

The Crypto Regulatory Decision states that providers wishing to offer crypto asset services (or any related services) must be based in the UAE or in one of the UAE’s financial free zones (i.e. Dubai International Financial Center or Abu Dhabi than the global market) and must obtain a license from the SCA. As part of the process, applicants must demonstrate that they will strictly comply with the UAE’s anti-money laundering and counter-terrorism financing laws, cybersecurity compliance standards and data protection regulations.

Dubai’s Blockchain Layout

Marwan Alzarouni, CEO of Dubai Blockchain Center, told the media that the UAE, especially Dubai, has always been forward-looking and proactive in any future technology. Rapidly evolving, cryptoassets and blockchain are no exception.

As early as 2013, the UAE launched the "Smart Dubai Initiative" (Smart Du initiative). The core part of the plan is to improve government efficiency through the use of blockchain technology, including using its own actions toActively promote the development of blockchain from 1.0 (payment tools) to 2.0 (financial industry applications), and then to the 3.0 stage (applications in other industries and government affairs management), and strive to make Dubai a global leader in this field.

In 2016, Dubai established the Global Blockchain Council, which currently has more than 30 members, including government entities, international companies and blockchain startups. Technology giants such as Microsoft, SAP, and Cisco are all members of this committee.

The Global Blockchain Committee held an industry theme meeting in 2016 and announced 7 new blockchain proof-of-concepts, including: medical records, secured jewelry transactions, ownership transfers, business registration, digital wills, Tourism management, improved freight transport. It can be said that Dubai is currently the blockchain R&D center in the Middle East.

In 2017, the Dubai government announced that Emcredit, a subsidiary of Du Economy, would cooperate with the US-based startup Object Tech Grp Ltd to create an encrypted digital currency called emCash.

In 2018, Dubai Prime Minister Sheikh Mohammed announced that the Dubai government will use blockchain technology in half of its government businesses by 2021.

In 2020, in line with the vision of "Du Blockchain Strategy 2020", Smart Dubai (Smart Du) fulfilled its promise of establishing a prosperous blockchain ecosystem in Dubai, Launched numerous use cases, a joint blockchain platform and Dubai blockchain policy. Government and private sector agencies are working on 24 blockchain use cases. These use cases cover eight sectors, namely finance, education, real estate, tourism, business, health, transportation and security.

The UAE has reportedly completed a digital KYC project called Emirates Pass, which will enable users to interact with all aspects of the legal process from remote locations, and is already building on its judicial notarization and Blockchain technology is used in authentication services.

The UAE has also proposed a plan to transform Dubai into the world's first city driven entirely by blockchain technology - the "Dubai Blockchain Strategy", making Dubai the happiest city on earth.

Hu Jie said that blockchain, as a new technology, is still in the stage of exploration and accumulation around the world. Dubai has adopted an open policy to attract blockchain companies and talents from around the world. In the future, blockchain Taking the lead in the development of the chain industry.

❷ Learn from the Chinese version of the "Messi Conference", can foodies in mainland China become real gold

< br />

"Macy Conference"

The "Macy Conference" may not be well-known to the public, but in the eyes of academic circles, it is a conference of great significance in the history of science , known as the "Third Scientific and Technological Revolution Pioneer Conference". 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, which has provided the basis for almost all scientific research in the second half of the twentieth century to this day. 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 -On the 18th, the Chinese version of the "Messi Conference" - Blockchain Mathematical Sciences 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, among Go and chess, the mostEventually machines will surpass humans, it’s just a matter of time.

But if it becomes incomplete information, such as playing cards, whether it is four-person bridge or four-person mahjong, computers are not at all The reason for human opponents lies in incomplete information. The same is true for decision-making. If your decision-making is based on complete information, machines will definitely surpass humans. But if you make decisions with incomplete information, then computers are still far behind humans. But unfortunately, all decision-making scenarios have incomplete information, and actual decision-making scenarios are all human. ”

As a senior catering project, Chihuahua Mainland has industry information advantages. No matter how powerful the algorithm is, it cannot be dismantled if it does not know the true cost operation information of the industry. Solve the correct game strategy. Based on this understanding, the Chihuahua Continental team is quite pleased that the algorithm we designed is at least operable.

But we Still not satisfied, we long for ourselves to be better!

Only mathematicians can do mathematics? Economist Zhu Jiaming emphasizes the value of professionals in applied fields

p>

Zhu Jiaming, Dean of the Digital Asset Research Institute

Professor Zhu Jiaming pointed out at the beginning that mathematics gave birth to the development of blockchain. From a practical perspective, Professor Zhu Jiaming also said that blockchain has the possibility to extend the branch of applied mathematics. However, academic discussions have always been cutting-edge. When it comes to practice, Professor Zhu also admitted: "At this moment, what new technologies are there?" Mathematical tools can be effectively combined with blockchain, which is a difficult topic to draw conclusions on. ”

The development of blockchain applied mathematics is not something that only mathematicians can do. There are many precedents in history for professionals in application fields to enter the field of mathematics.

p>

Professor Zhu Jiaming gave an example: "For example, when physicists, aerospace engineers, geologists, biologists, and economists encounter practical problems, they Mathematical tools are input into their research fields, or some new mathematical methods are invented.

Here is an example that seems far away from us but is instructive., which is the combination of biology and mathematics. The combination of the two gave rise to 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, and biomathematics uses mathematical methods in biology. and form new mathematical methods. ”

It can be seen that the path of exploring applied mathematics in blockchain also requires the efforts of people in the industry. Encouraged by Professor Zhu Jiaming, Foodie Mainland As an explorer of the catering blockchain industry, I have finally found another historical mission to improve myself - exploring mathematical methods for catering blockchain applications.

Young people can be fearless. Wang Feiyue, an expert from the Chinese Academy of Sciences, tells you how invincible human imagination is. ···

Wang Feiyue, Director of the State Key Laboratory of Complex System Management and Control, Chinese Academy of Sciences

We are fearless because of our youth, but our excited hearts have not yet calmed down. Teacher Wang Feiyue’s views on imagination are so amazing that we want to go against the grain.

Wang Feiyue, director of the State Key Laboratory of Complex System Management and Control of the Chinese Academy of Sciences, gave us a vivid walk through the history of science. When he came to artificial intelligence, he quoted the "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, human language. The intelligence that can be expressed is far smaller than the intelligence we imagined. This is consistent with the Tao in the Tao Te Ching. Later, archaeologists discovered that, alas, it was actually not two sentences, but three sentences, "Tao, Tao, Very Tao", which happened to correspond to these three levels. ”

The Chihuahua Mainland team deeply agrees that we have always had a consensus, that is, under the myth of technology, it seems that there are no people in the world except machines. Generally, 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 computing intelligence, it is already possible In the era of "self-learning" through "raw data input", the more important role of human beings is:Go beyond 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 observation of experiments, 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 mechanism" 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.

❸ Block What are the application examples of chain in the tourism industry

1. Consumption points management
Leou online cultural tourism platform is the world’s first to cover the six major areas of food, accommodation, transportation, travel, shopping and entertainment. The blockchain tourism platform in the field of tourism transforms the original old points system of the enterprise to a certain extent and converts it into new points independently issued by the enterprise with blockchain as the underlying technology, realizing the free trading and exchange of points, and maximizing the Make full use of the services and functions of points to help service providers attract customers and help travel consumers gain greater benefits.

In addition, Singapore Airlines (SIA) also announced in 2018 that it would launch a blockchain-based customer loyalty KrisFlyer program for flyers.
4. Track pilots’ professional certificates and qualifications

France’s Airbus, a participant in the Hyperledger Blockchain Alliance, is also exploring the possibility of blockchain applications. The test project is to use zone Blockchain tracks pilots’ professional certificates and qualifications, among other things.
5. Credit consumption management
On the Airbnb platform, reputation is extremely important. Users whose credit reaches a certain level can rent specific types of houses. Airbnb uses blockchain technology to better establish a reputation platform for merchants and travelers, and to effectively store identity information.
6. Digital Identity Authentication
Joanne Zen, the founder of Backpack Chain in New Zealand, is leading the team to create the BTA system, using underlying blockchain technology combined with Internet applications to create personal electronic digital identity authentication. When a user registers on the Backpack Chain APP, in addition to the regular registration process, the user's passport also needs to be scanned and facial recognition information uploaded, thus generating unique mobile personal ID information in the world. Each ID information owner will have a key, which is known only to the information owner.
7. Verify house information
Airbnb provides more than 2 million house information in 191 countries and has received 60 million customers. The P2P hotel website has achieved certain success in optimizing the one-stop process of hotel rental. It is also exploring the verification of house information, establishing a text message communication system to allow customers to communicate with landlords, and improving the payment experience.
8. Electronic identity management
In Estonia, blockchain technology has been used to develop electronic identity projects. It is reported that the country allows non-Estonian residents to apply to become e-citizens, similar to a permanent residence permit or identity card, which enables these residents to enjoy a range of services provided by the country. Currently, Estonia uses this program to encourage talented people from all over the world to start businesses in the country. Such plans would provide a significant boost to tourism in some destinations. You can follow bitmom for more

❹ When will the New York Bitcoin Conference be held

According to foreign media reports, although the price of Bitcoin has fallen sharply this year, the cryptocurrency conference is still a A big deal.

This week, the well-known Bitcoin news website CoinDesk will hold a three-day New York Bitcoin Conference in New York City. The ticket price is about US$2,000. It is expected that 4,000 people will attend this conference, which is a lot more than last year's 2,700 participants. Therefore, ticket sales for this conference will reach at least $8 million.

In the few days that the New York Bitcoin Conference was held, there were 20 other conferences held at the same time.The ticket prices are also very high. Three years ago, when the Consensus conference was first held, only 400 people attended. The conference is now a major feature of Blockchain Week NYC events.

Around the time of the Consensus conference last May, the price of Bitcoin soared to about $2,000. Of course, this is also the result of the first-ever TokenSummit Summit and Ethereal Summit.

Since then, the price of Bitcoin has soared, successfully attracting the interest of Wall Street, and surpassing $10,000 for the first time after the Consensus Invest conference in November. In December last year, the price of Bitcoin reached its peak, exceeding $19,000. However, its price has dropped by more than half since then.

Strong speaker line-up

This year’s speaker line-up demonstrates that the cryptocurrency industry is taking important steps towards the mainstream. Jack Dorsey, co-founder of the microblogging site Twitter, is preparing to give a speech at the Consensus conference on Wednesday. His mobile payments company Square also launched a bitcoin transaction service this year. Other conference panelists include government officials and startup leaders.

“The Consensus conference is very famous. If you give a speech at the conference, it means that you are also very famous.” Michael Oved, co-founder of cryptocurrency exchange AirSwap )explain. He was also the organizer of the Fluidity Blockchain Conference held last Thursday.

He said he deliberately lowered the price of tickets to the Fluidity conference he held, pricing them at $150-$250. Because he thought it was a "good opportunity for us to communicate what we're working on." Oweide said the Fluidity conference had about 700 attendees and generated about $140,000 in ticket sales.

“The irony is that organizers charge high fees but never pay speakers. These speakers are the ones who care most about the development of the blockchain community and are the most enthusiastic People who share new updates,” she posted on Twitter on April 28.

She will speak on stage at the Ethereal Summit and Consensus conference held this week. “I was not paid to speak at either conference,” she said. She also added that "online live streaming is a good way for the public to watch the content of the meeting."

"There are too many meetings, it's crazy"

Various meetings have become very popular, It’s also very lively, but we don’t know whether they ultimately help startups, especially those that are not well managed.

“It’s crazy how many meetings there are now,” Oweed said.In the San Francisco Bay Area, there is a conference about blockchain every week. We can easily get distracted by these meetings. "

However, some people are convinced that these meetings will eventually be the catalyst for Bitcoin's price recovery.

"After each Consensus meeting, the price of Bitcoin will rise. This fact strongly supports our view that Bitcoin’s price has bottomed this year. Tom Lee, co-founder of market research firm Fundstrat Global Research, said in a research note on May 7, “During each session, the price of Bitcoin will increase by 10-70%. "

He also added, "Given the significant increase in attendance, we believe that all cryptocurrencies will see similar price increases. ”

❺ Why blockchain investment must not just listen to “actors”

Yesterday, the Boao Asia Blockchain Forum attracted widespread attention. It is not technology research and development and application design that have achieved success. Important results, just because the performances of special actors on the forum have been criticized.

For investors, although blockchain technology will have better development in the long term prospects, but if you want to invest in the blockchain, you still have to fully consider the corresponding risks.

Ordinary investors who follow the trend of investment need to pay attention to that many so-called investment projects are actually just If ordinary investors enter the MLM scam in the name of "blockchain" rashly, they are likely to end up either being "cut off leeks" or falling into the MLM scam.

Blockchain Investment must not just listen to the "actors".

❻ Can Huobi be used in Puerto Rico?

Yes. Global in the field of digital currency Competition is intensifying, and whether they are traditional powers or a corner of the world, they have all made positive statements.

The Caribbean is becoming a global region with friendly regulatory policies and a high proportion of cryptocurrency usage. Star regions in the blockchain industry and cryptocurrency field, including countries (regions) such as Jamaica and Puerto Rico, are actively embracing blockchain and cryptocurrency with practical actions to support the development of the industry. A large number of companies and institutions in the blockchain and cryptocurrency industry have also Actively deploying in this area.

TRON founder Justin Sun is naturally indispensable in this craze. From Grenada to Dominica, the Caribbean region that Sun is deeply involved in is becoming an important part of the development of TRON and Huobi. Breakthrough.

Deeping in the Land of Promise

A survey released this year by the international payment giant Mastercard stated that as many as 51% of Latin American and Caribbean (LAC) consumers Respondents reported completing at least one cryptocurrency-related activity in the past 12 months. More than one-third of respondents in Latin America or the CaribbeanVisitors choose to use stablecoins to pay for “daily life.”

For Caribbean countries, historical and practical needs have led them to actively participate in the research and development and application of cryptocurrency.

Developing cryptocurrencies is one of the ways Caribbean countries are coping with high inflation rates. According to a study by Cornell University, many Caribbean countries face high inflation and the actual purchasing power of local currencies fluctuates greatly. Many residents choose to store their wealth in assets such as gold and U.S. dollars, and are relatively more willing to use cryptocurrencies as storage. means of assets. At the same time, the region's political landscape is relatively volatile, and many residents prefer to store some of their wealth in assets that are difficult to seize and track. Bitcoin is a popular digital currency that reached a high of approximately $19,500 in December 2017, but its roller-coaster ride is not unfounded. This "demon coin" suffered another setback this week, once again falling back below $8,000.

At a blockchain conference this week, cryptocurrency experts and entrepreneurs are betting their fortunes on Puerto Rico as the next hot spot for doing digital currency business. Puerto Rico government officials have also said they will support the nascent industry. Puerto Rico’s Minister of Economic Development and Commerce Manuel Laboy announced on Thursday (March 15) that an advisory committee will be established to enable the growth of blockchain business locally. Even the United States provides tax incentives for related U.S. companies in Puerto Rico.

For Puerto Rico, which has been plagued by population loss and debt crisis for many years, the local economy is sluggish, and the referendum to join the United States to become the "51st state" has been repeatedly frustrated, it is necessary to find industries suitable for experienced people as soon as possible. The breakthrough point is crucial, especially after the Caribbean island suffered a "devastating" hurricane disaster last year. In order to achieve a magnificent turnaround as soon as possible, the local government has decided to embrace the popular emerging industry of virtual currency.

The above approach is a win-win situation for investors, Laboy said in an interview with reporters at a three-day blockchain conference in San Juan, the capital of Puerto Rico, this week. . For its part, Puerto Rico is eager to be part of the expanded cryptocurrency market. He said that many existing blockchain development positions are unfilled, but currently there appears to be only one qualified candidate for the job.



Puerto Rico is looking for ways to get relevant companies to spend money on it

Brian Kelly, chairman of BKCM, a digital currency asset management company, said, Cryptocurrency is a new business. The government of Puerto Rico is looking for new ways to attract investment from relevant companies. FX678 reported that Kelly said during the "Fast Money" program that he had previously found countries such as Singapore and Switzerland to be suitable for conducting cryptocurrency businesses.The place. Now it is discovered that Puerto Rico is also a place where you can expand your cryptocurrency business and open a store to operate cryptocurrency business there. He said: “Now what we want to think about is, how to expand the digital currency business in Puerto Rico?”

As regulators are worried about Bitcoin, Google will follow Facebook to ban its The cryptocurrency market has been in trouble recently due to advertisements for digital currencies and initial coin offerings (ICOs) being placed on search systems and advertising networks including YouTube. Over the past week, the prices of Ripple, Ethereum, Bitcoin, and Litecoin have all fallen due to panic selling. Patrick Moynihan, chairman of Blockchain Instries, said this may be a concern for people in the industry.

Puerto Rico may be the next place to get rich in cryptocurrencies. Why?

A number of crypto millionaires and billionaires have purchased properties in the Caribbean island of Puerto Rico. Puerto Rico has become a utopia for the digital currency world. Puerto Rico is happy to provide a safe haven for those looking to protect their crypto assets. The island charges no personal income tax or asset income tax, and also offers business tax concessions. What's even more tempting is that U.S. citizens and their capital industries can freely enter and leave the island without cumbersome customs clearance procedures.

As industry leaders debate whether cryptocurrencies are just a bubble, can Puerto Rico become the next place to get rich in digital currencies, as some hope? ? Let us wait and see.

❼ How blockchain empowers digital city construction | Blockchain Classroom

Cities are actively embracing digital technologies such as blockchain, the Internet of Things, and artificial intelligence to accelerate urban economic growth and improve the quality of urban life and the sustainable development of the environment. The digital transformation of cities also provides a good experimental field for the value mining and application of blockchain technology.

The construction of a digital city not only requires city-wide coverage of connected devices, but also needs to consider the collection of full-process data and automation of decision-making. The data on the blockchain has the advantages of being difficult to tamper with, safe and trustworthy, and can help the construction of digital cities in the following aspects:

The blockchain adopts a distributed storage structure, so each node in the system All data on the system is stored, making the data open, transparent and easy to manage. At the same time, cryptographic technologies such as privacy computing integrated in the blockchain can achieve safe sharing of data without leaking data privacy, or by setting access permissions, authorized nodes can obtain the corresponding data, thereby ensuring that the dataSafety.

Thanks to the distributed network structure, even if a single or a small number of nodes fail, the entire blockchain network can still operate normally, greatly reducing the risk of system failure due to network attacks or technical problems. Compared with traditional cities, digital cities rely more on technology. Improving system stability will also help maintain the normal operation of digital city life.

Digital city innovation case empowered by blockchain

Dubai’s digital city project integrates blockchain, Internet of Things, artificial intelligence Smart and other new digital technologies are committed to making Dubai "the happiest city in the world".

A major innovation in Dubai Digital City is to strive to realize the on-chain operation and management of all government data transactions in 2021, and realize the electronicization of an average of 100 million paper-based processes per year. This blockchain-enabled digital reform is expected to save process management costs worth US$1.5 billion, save 25 million hours of process processing time, and reduce 114 million tons of carbon emissions. In addition, the Dubai government is actively cooperating with many blockchain companies, focusing on key areas and implementing multiple blockchain application cases.

The European Commission also recognized the importance of blockchain in reforming government services, and established the European Blockchain Partnership in 2018, covering local law enforcement agencies, national governments and the private sector in Europe. enterprise. The Commissioner of the European Commission’s Department of Digital Economy and Society is also confident in the value of blockchain technology in digital city construction and stated: “We believe that all public services in the future will be built on the infrastructure of blockchain.”

For example, the government of South Tyrol in Italy has used blockchain technology to digitize citizen data. Residents only need to register basic personal information once to enjoy services provided by different government departments, streamlining government affairs processing procedures, reducing costs and increasing efficiency.

At the same time, based on blockchain technology, Estonia has built a national health information electronic system. Through this blockchain platform, doctors can easily query patients' blood tests, recent treatments, X-ray examinations and other related data with authorization. Patients can also clearly check their medical records, prescriptions issued by doctors and other information. The characteristics of data on the blockchain, such as being difficult to tamper with and fully traceable, can ensure the security and integrity of the data on the platform.

Wanxiang Blockchain has also begun active exploration in blockchain-enabled digital city construction, using blockchain to integrate new digital technologies such as the Internet of Things and artificial intelligence to build a safe and trustworthy digital base. And through technologies such as private computing, knowledge graphs, digital twins, and distributed business incentives, we can manage production and life in a more refined and dynamic way, forming an intelligent, low-carbon, and comfortable resilient city with technology integration, comprehensive application, and high-end development.city, helping to build a harmonious urban ecology with economic prosperity, job happiness, and sustainable development.

Wanxiang Blockchain is committed to building a digital city that “truly understands you”. Through the integration of blockchain and new technologies, a trusted digital base is built to allow every resident to have an exclusive digital avatar. Truly gain data sovereignty and enjoy a safe and comfortable urban life without having your privacy protected from prying eyes.

❽ The largest Mediterranean smart city project uses blockchain technology platform

According to the Huobi Blockchain Application Research Institute, the MENA headquarters of Locus Chain Foundation (LCF) and the largest The Tunisian Economic City (TEC), a Mediterranean city project, signed a strategic cooperation agreement to use Locus Chain blockchain technology as its settlement currency and service platform.

Locus Chain is the foundation of a next-generation blockchain platform headquartered in Singapore, with technology offices in South Korea and Japan. Locus Chain Foundation CEO Lee Sang Yoon and Tunis Economic City General Manager Dr. Riadh Khalifa Toukabri signed the agreement at the LCF Singapore headquarters in the presence of senior officials from both parties.

Jointly owned by Tunisia and Saudi Arabia, TEC is a large-scale project on the eastern peninsula of Tunisia. It covered a total area of ​​90 square kilometers and cost US$50 billion during its first ten years. The city consists of 14 large-scale thematic districts and is expected to become an international business and technology center connecting Europe, Africa and Asia. It will also serve as Africa's gateway to Europe and complement the economic growth of the GCC countries.

This cooperation agreement aims to apply the blockchain platform to entire urban construction projects as the basic technology and settlement currency for various industries such as finance, communications, medical care, shopping, autonomous vehicles, artificial intelligence, etc. The upcoming new collaboration is a gathering place for startup giants and fourth-generation tech gurus. It aims to digitize the business and public sectors by realizing a large-scale economic and urban development project on Tunisia's east coast.

Lee Sang Yoon said: "TEC is one of the most advanced smart city projects the world economy has ever experienced. When applying the 'Locus Chain' blockchain platform to the TEC project, it will be used It will provide an ideal management and service system to ensure high transparency and security in the entire industry."

The daily closing line has stood above it for 12 consecutive trading days. It shows that the trend at this level is still strong; at the 4-hour level, the moving average system (5, 10, 20) presents a bull arrangement pattern, with a limited upward slope, and the MACD indicator continues to shrink compared with the green column representing the energy of the bulls; at the 1-hour level, the moving average system continues to Wrapping around, MA60 still shows a clear upward trend, and the divergence between volume and price is relatively obvious.

Industry aspects OKCoin has learned that the Dubai government has established a partnership with British startup ObjectTech to bring blockchain-level security to the emirate’s airports. ObjectTech said this week that it is working with the Dubai Immigration and Visa Department on research and development A digital passport that significantly reduces manual verification at Dubai International Airport.

Through blockchain technology, the startup said the digital passport will be able to integrate a feature called "autonomous identity management" aimed at achieving privacy protection. With this feature, travelers can decide which departments or individuals have the right to view their passport information.

ObjectTech co-founder and CEO Paul Ferris mentioned in a blog that the goal of this project is to speed up the border process and provide a safer environment for entry and exit personnel. In addition, Travelers also have full control over their electronic data. The pilot project is expected to be ready by 2020, but the detailed timeline for the project has not yet been made public.

This project is part of the commitment of the Dubai government, which states that it will be 10 years ahead of the rest of the world in public services.

As part of achieving its goals, the Dubai government has launched the second round of the Dubai Future Accelerator Program. Currently, 28 innovative companies have signed up to participate in project research and development, involving public sectors such as healthcare, education and public utilities. cause.

❿ After reading this article, you will have a thorough understanding of the blockchain

In this article, all the content I introduced is about the blockchain in today’s world. The fact that the blockchain field has already happened is not some imagination or opinions about the blockchain. I think that as long as you read this article carefully, you will easily have a basic and accurate understanding of blockchain.

The main content of understanding blockchain in just ten minutes is divided into four sections. 21 topics and 4 sections are:

The first national blockchain strategy.

Second, Bitcoin and its literal representation involve four topics.

Third, blockchain and its technical logic involve 13 topics.

Fourth, blockchain empowers the economy and society, involving three topics.

Let’s first look at the first part of the blockchain national strategy, the first part of the blockchain country. Everyone knows that we humans have experienced six information revolutions. Seven or eight years ago, the first information revolution created primitive language, social tacit understanding, and the second information revolution saw the emergence of writing. The third information revolution in feudal society invented papermaking and printing, and the fourth information revolution in the late 19th century invented radio.

In the fifth information revolution of the 20th century, television appeared again. So, nowComputers and the Internet appeared in the sixth information revolution. The emergence of computers and the Internet has given rise to the rapid development of various new technologies. Especially in 2020, the digital economy has experienced epoch-making development.

Why do you say that? The characteristics of high bandwidth, low latency and large connections in the 5G era have enabled the implementation of the four major technologies of ABCD.

What are the four major ABCD technologies

The a here refers to Artificial Intelligence, which is artificial intelligence technology.

B refers to Blockchain, blockchain technology.

C refers to cloud computing cloud computing technology

D refers to big data technology.

The word blockchain is now completely popular all over the country. On October 25, 2019, the Political Bureau of the Central Committee of the Communist Party of China announced the development of blockchain technology. The current situation has been collectively studied, so the requirement of this meeting is to use blockchain technology as the core technology.

As an important breakthrough for independent innovation, it is necessary to accelerate the innovative development of blockchain technology and industry. On April 20, 2020, the National Development and Reform Commission officially included blockchain into new infrastructure. Blockchain, why do you think it is so awesome? Let us say that blockchain is not an extension of the Internet, it is a subversion of the Internet. In the future, many, many technologies will grow on this blockchain and realize blockchainization.

So, how can we accurately learn and understand the blockchain?

We found that among the four major technologies of ABCD, only the block is naturally built-in It's financial. Therefore, we must learn and understand blockchain from the IT perspective and the financial perspective, and even learn and understand blockchain from the level of national governance. If you only study and understand blockchain from an IT perspective, it is impossible to understand the huge influence and influence of this technology. Then, your understanding of this will be biased. Even more, you may disapprove of blockchain technology. In addition, in the process of learning about blockchain, you should also pay attention to the fact that it has many new terms, so you need to concentrate on understanding it step by step.

Let’s first understand blockchain from a financial perspective.

Bitcoin and its birth performance

To understand the blockchain, it involves Bitcoin, and the birth of BitcoinWell, it is inseparable from the evolution of currency. We know that currency is a special commodity that is separated from commodities and serves as a fixed general equivalent. In fact, we humans have used a lot of currencies, including physical currency, weighing currency, paper money, accounting currency, etc. As for accounting currency, it includes electronic currency and digital currency. Electronic currency itself is not a currency. It is just used to represent the same amount of currency. It is a token.

Then the total amount of his tokens will not increase due to the increase of electronic currency. Alipay, WeChat, payment, and online banking are typical electronic currencies. As for digital currency, it is itself a legal currency. The total amount of this fiat currency will increase with the increase of digital currency. We know that when it comes to physical currency, we humans have actually chosen many things as general equivalents.

Weighing currencies are some heavy metals. Later, people chose gold among the heavy metals. Why choose gold? Because gold has the characteristics of rarity, divisibility, and the most stable chemical properties. What needs to be noted here is gold. It is not issued by any country. It is provided by nature. of. Your country's total amount is as much as nature provides. Therefore, the country does not need to provide credit guarantees for the value of gold.

However, as for gold, it has some flaws in its use, and it is difficult to carry when you go out again, so there are descendants. Paper money appeared in the Northern Song Dynasty. At that time, paper money was not currency in the current sense. The currency at that time was still gold, but we used paper money to represent gold. We called it the gold standard. The gold standard is the gold standard, which is a monetary system with gold as the standard currency. The core essence of the gold standard is that how much currency a country issues should be decided based on how much gold your country has. It does not mean you can issue as much currency as you want.

At that time, the Great Depression of the United States reached January 10, 1934. On this day, the newly elected President of the United States made a very important decision to abandon the gold standard and issue 3 billion US dollars. Think about it, abandoning the gold standard, in theory, means that he can issue as much currency as he wants. Even if there is no gold in the treasury, he can issue banknotes as long as he wants to. Then someone will ask, if you issue so many words, can you still exchange them for gold of equal value?

Look at the banknotes at this time, they have been separated from gold, and national credit has emerged. , this, we call it currency guaranteed by national credit. Now, when mainstream countries issue currency, they also issue it with national credit as a guarantee.

What’s goodWhat's the advantage? The advantage is that it can regulate the economy. When the economy is not doing well, a little more power can drive economic development. The increase or decrease in this variable will cause a chain reaction of the entire economic aggregate. This is the multiplier effect in economics. Once a country masters this thing, some countries will be fascinated by it. But if it is not well controlled, it will lead to national credit bankruptcy. As a result, many people began to reflect. This reflection is, when issuing currency, is it better to use national credit as a guarantee, or is it better to stick to the gold standard based on the total amount of gold. This question involves the birth of Bitcoin
