1. What are the classifications and applications of blockchain projects

From the current mainstream blockchain projects, blockchain projects mainly fall into four categories: First Category: Currency; Category 2: Platform Category; Category 3: Application Category; Category 4: Asset Tokenization.

Coins mainly serve as the "medium of exchange" in the field of blockchain assets. The medium of exchange refers to general equivalents, such as gold and silver notes in the past. (Trade blockchain assets on "Bihui Exchange")

Platform projects refer to the establishment of technology platforms to meet the development of various blockchain applications, which can reduce the cost of developing applications on the blockchain. threshold.

The scope of application projects is relatively wide, covering many fields such as finance, social networking, games, property rights protection, etc. It is also the fastest growing field of blockchain assets.

The asset tokenization project refers to the blockchain mapping of physical assets, that is, the physical assets are put on the chain. Currently, there are no more than 10 varieties.

01 Currency

The first category is currency projects, which are also the earliest blockchain projects. Currency projects mainly include projects such as Bitcoin and Litecoin. In addition, there is another type of asset that has the characteristics of anonymity. Its main functions include realizing payment while protecting the privacy of both parties. The well-known ones include Dash, Monero and Big Zero that use zero-knowledge proof. Coin (Zcash), etc. Currency mainly serves as the "medium of exchange" in the blockchain asset field. The medium of exchange is the general equivalent that you use to exchange for goods. For example, in the past, gold, silver, and banknotes could be used as media of exchange. There are currently more than 2,100 types of digital assets in the world, and the number of currency blockchain projects has grown rapidly recently. As of June 2018, Bitcoin still has the largest market value.

02 Platform Category

The second category is platform blockchain projects. The main function of platform blockchain projects is to establish a technology platform to meet the needs of various blockchain application development. The required technical requirements; simply put, platform applications allow developers to directly issue digital assets on the blockchain, write smart contracts, etc. A smart contract is a computer program that runs on a blockchain database and can be automatically executed under conditions set by its source code.

For example, if you develop a smart contract based on a house rental agreement on the blockchain, when the owner receives the rent, it will trigger automatic execution and give the apartment's security key to the tenant.

The main function of platform blockchain projects is to establish an underlying technology platform to allow developers to develop applications on the underlying technology platform. A considerable number of platforms are still under development. As of June 2018 , the one with the largest market value is Ethereum.

03 Application Category

The third category is application blockchain projects. Application projects are developed based on blockchain development platforms (such as Ethereum) and can solve various problems in the real economy. Blockchain projects that address many issues in the field.

For example, the blockchain-based prediction platform Augur, based on the blockchainGolem, a computing power trading platform, VeChain, a luxury goods traceability platform based on blockchain, and OmiseGo, which provides asset exchange and transfer services based on blockchain. Using blockchain technology, these projects can better solve trust issues, cross-border circulation and other issues. At the same time, using smart contracts and tokens on the blockchain, automatic execution can be better realized, greatly improving the efficiency of social and economic activities. efficiency. The scope of applied blockchain projects is relatively wide, covering many fields such as finance, social networking, games, property rights protection, etc. It is also the field where the market value of blockchain projects is increasing the fastest.

04 Asset Tokenization

The fourth category is asset tokenization blockchain projects. Asset tokenization refers to linking blockchain assets to physical assets such as gold and U.S. dollars. , is a blockchain mapping of physical assets. As of February 2018, there are no more than 10 varieties. The more typical representatives are USDT, which is benchmarked against the US dollar, and Digix Dao, which is benchmarked against gold. Each DigixDAO token represents 1 gram of London gold. Silver Market Association certified gold. Asset tokenization has the advantages of convenient transactions and safekeeping. First, asset tokenization makes transactions easier. Because blockchain assets can be split, they have better liquidity.

For example, currently the real estate needs to be transferred as a whole. If the real estate can be tokenized, it can be purchased in pieces, making transactions more convenient. Secondly, tokenization of physical assets is more conducive to safekeeping. In physical transactions such as gold, it is easy to cause wear and tear and cause losses. However, after tokenization of physical assets, there is no need for physical transfer, which is more conducive to the custody of physical assets.

2. What will happen to the world when blockchain meets cloud computing?

Blockchain meets cloud computing, just like a fish meets water, the world will become like a fish. A new door will be opened, and human civilization will advance further. Clouds are like network points, and clouds are like network nodes, which eventually converge into the sky. Chains are like connections that cannot be broken. They can tightly string together clouds. The combination of the two forms a huge data sharing. platform.

1. The principle of cloud computing is fractional computing, which decomposes huge data calculation processing programs into countless small programs, and then returns these data processing results to the user. A huge computing project is directly handed over to Cloud computing saves users time and energy; blockchain is a new application model such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is also a docking and storage node, and its functions are similar to those of cloud computing. Complementing each other, the birth of these two major technologies in the information age will definitely shock the world.

3. What is the future of IPFS?

IPFS—also known as "Interstellar File System". To put it simply, it is a peer-to-peer distributed file system (the same as Bitcoin technology). Through the underlying protocol, files stored on the IPFS system can be quickly accessed anywhere in the world without being affected by firewalls. (No network proxy required). The Internet protocols we use today areCalled - Hypertext Protocol HTTP. This protocol has hyper-centralized characteristics.

In other words, when you download files from the Internet or browse the web, you can only get the information you need from one data center at a time. If this data center fails, is restricted or attacked, there will be problems such as file loss or web pages that cannot be opened. For example, the data you have stored in a certain cloud disk suddenly cannot be downloaded, or the webpage you want to browse cannot be opened due to some policy reasons.

The purpose of IPFS is to solve these problems. In some ways, IPFS is similar to the Web. You can also link to Internet addresses based on IPFS. But IPFS is decentralized, and it does not have the main network failure problem of the Web. Therefore, it is not a fantasy for IPFS to completely replace HTTP!

Compared with computing power mining, memory mining is intensive farming. Not only is operation and maintenance particularly important, but due to the particularity of storage, mines are basically arranged in IDC computer rooms. Temperature, humidity and dustproofness must be well controlled, and power outages and network outages must be prevented, and 24-hour operation is required. Hours of real-time monitoring by operation and maintenance personnel. It's like a flower in a greenhouse, unable to withstand the wind, sun and rain.

Moreover, the income from Cunli mining is also related to the area where the mining machine is located, especially areas with high network traffic, that is, big cities. For example, if you participate in the retrieval market and your mining machine is located in a sparsely populated place, no matter how fast it is, the output will not be high. Therefore, mining pools should be established in places with high population density, such as first- and second-tier cities and provincial capital cities.

In the era of the Internet of Things, artificial intelligence, blockchain, cloud platforms and edge computing, computing and storage have always been the foundation for the Internet of Everything. Today's well-known cloud service providers, such as Amazon's AWS, Google Cloud, Microsoft's Azure, Alibaba Cloud, Dropbox, etc., have a combined market value of more than one trillion US dollars. As a star project of distributed storage, IPFS&Filecoin is likely to replace these cloud service provider giants in the future and open a new era of storage mining.

The prospects of IPFS are very promising, and it is currently a project that many investors are optimistic about.

InterPlanetary File System IPFS (InterPlanetary File System) is a globally oriented, point-to-point distributed version of the file system. The goal is to supplement or even replace the Hypertext Transfer Protocol (HTTP) that currently dominates the Internet, integrating all Computing devices with the same file system are connected together.

I believe everyone knows that Bitcoin has a lowest price of US$0.0025 and a highest price of US$20,000, with an increase of up to 8.031 million times. Early Bitcoin miners used computers to mine thousands of bits.currency, now equivalent to nearly 100 million yuan. This is what is often referred to in the industry as the “first mine bonus.” Filecoin was first publicly issued in 2017 and raised more than $250 million, making it the largest ICO in history.

I want to try the best hosting, because the main factors of IPFS mining are bandwidth and location, so I can grab orders. In fact, home mining machines cannot get orders at all, so there is naturally no profit. At present, the ipfs mainnet has just been launched, so it is basically in the promotion stage now. It is a time period with high cost performance, and future benefits are worth looking forward to.

After looking at many of the answers, they were all given a long time ago. Let me give a brief introduction to the current situation.

Domestic situation: Domestic blockchain projects are not optimistic. It is in a gray area and is now subject to some control and expulsion by the country. However, IPFS and Filecoin, the incentive layer of IPFS, have not yet been affected or affected.

The main reasons are: 1. The IPFS project does not consume enough energy. Large, it will not affect the current carbon neutrality and carbon peak; 2. IPFS has practical application prices, not only at the personal application level, but also corporate information and national information security are guaranteed. The country and domestic Internet giants are laying out corresponding IPFS construction , is also being developed as a new national infrastructure; 3. One of the advantages of IPFS is to reduce the cost of storage, which is needed by both enterprises and countries. Embracing new technologies and reducing costs is what everyone is pursuing; 4. IPFS In order to become a leading blockchain project, it will only be developed as a king-level project for blockchain distributed storage.

The above four points are some of the reasons why the IPFS project can still operate normally in China so far. Similarly, we also need to see clearly the risks that exist in the future. In the future, after IPFS stands on the cusp of the WEB3.0 era, It is bound to meet various challengers and regulators. Whether it can cope with the regulators' policies and regulations is a big problem. For now, at least the IPFS project IPO has been legally certified. This is the current comparison. The good news is that the challenger SWARM project is still coming fiercely before the mainnet goes online, and it is bound to kill IPFS. However, after the SWARM project goes online, everyone finds that the SWARM project still cannot shake IPFS in the distributed storage world. As ordinary people, after understanding the IPFS project, we can think about it. The entire plan of IPFS and the economic model of Filecoin are in line with the current trend of Internet development. Can challengers establish more advanced plans? These are the crises that IPFS needs to face if it can be implemented smoothly.

In summary, IPFS will be an important engine leading the development of WEB3.0 now or in a few years. The future is promising, and IPFS is bound to create a new Internet era

You must know that IPFS aims to build an open storageThe storage market protects the storage and security of data through copy certificates and space-time certificates. During the data storage process, you only need to submit a copy certificate, and then submit a space-time certificate every 30 minutes, 48 ​​times a day, through a series of complex Proof mechanism to ensure that the storage is saving data for users, and has a complete and very strict penalty mechanism.

As technology continues to develop and information content continues to enrich, our requirements for storage are getting higher and higher. As far as the storage market is concerned, with the huge amount of data, storage has a broad market space. Existing centralized storage faces bottlenecks such as high costs and vulnerability to attacks, and data storage is more free. IPFS distributed storage was born to solve this problem. It is more secure and reliable. In the traditional storage market, IPFS has great advantages and opportunities for us to seize and get our share of the pie.

1) DAPP and other related application software

If you are interested in the official event Slingshot, you can check out the many different applications based on IPFS, such as cloud disks, videos, music, There are many other implementation examples such as medical imaging cloud system. At the same time, there will be many tools for IPFS.

2) Integration with other blockchains

ChainX previously announced that it would bridge with IPFS, which is an ecological expansion for IPFS.

3) IPFS officials have also announced

In the future, a decentralized lending platform for the Ethereum ecosystem will be built. In this case, the economy of IPFS will be promoted with the help of the Ethereum ecosystem. cycle.

In essence, IPFS is the most basic storage tool, which enables the free flow of data and value transfer through IPFS. There are many implementations based on IPFS, whether it is DAPP, smart contracts, or combined with other blockchains, they are all implemented in different ways. Therefore, the business prospect of IPFS is to use the value transformation brought by distributed storage technology to become a broad blue ocean of value.

The IPFS mainnet has just been launched, which is a new beginning. The development of IPFS will also face various opportunities and challenges. Ecological development is a key factor that determines whether the IPFS vision can be realized. First, from the perspective of commercial implementation, slingshot is actually a manifestation of the protocol laboratory's encouragement of commercial application development. Now a single spark can start a prairie fire, but it still depends on the subsequent construction of the business ecosystem.

In addition, there is real data storage, which is also an important aspect of whether IPFS can develop healthily in the long term. At present, there is still a certain amount of junk data in the IPFS network. Due to reasons such as the increase in storage computing power, the proportion of actual data in later development will definitely continue to increase, so that IPFS will be in a relatively healthy state.Health's development status.

The IPFS ecology in China is divided into four major parts:

The first is the application ecology, which is mainly about the discovery and implementation of the application level;

The second is It is a community ecology, mainly maintaining the open source community, and hopes that more enthusiasts will join;

The third is the knowledge output ecology, because the IPFS system is too complex and needs someone to explain and export knowledge. , At present, there are not many people in China who can truly export knowledge;

The fourth is the IPFS ecosystem, and the time is ripe.

As a decentralized big data system, it will change the governance mechanism of the Internet, and community governance is also an important aspect. Whether the community develops well and healthily and whether it is guided by positive energy is crucial to the development of IPFS. The governance of the entire community will be closely related to every participant. Every member of the community is crucial and needs to work together to maintain the development of the community, including you and me.

IPFS is currently in its preliminary stage, and it still lacks many roles in its ecosystem, such as data markets, c-side entrances, etc. Developing the ecosystem is a long and arduous process. Nowadays, we can see the official attention of IPFS in this field, and we can also see some good tools.

We must believe that the prospects and future of IPFS are bright, and it will continue to move forward in the Web3.0 era that leads distributed storage to the future.

Through the above content, I believe you are no longer unfamiliar with IPFS, and its future and value are obvious to all. The completion of a project cannot be accomplished overnight. It is impossible to complete this vision in a short time. This is a long-term process. I am optimistic about it. Are you as optimistic as me?

p>

I don’t know if this is what you are talking about. IPFS is a set of file protocols that can achieve distributed storage and network sharing. This is still a very new thing, but p2p is now strictly regulated by the country. For decentralized file sharing like this in China, I think the supervision will be very strict. When he said that the files will be saved permanently, I think there is a question mark. For specific technical details, you can ask students with professional and technical backgrounds.

As mentioned in the previous video, IPFS is the underlying protocol that benchmarks HTTP. It solves the current problems of poor data transmission security, high cost, and low availability. It is currently based on IPFS There are already many applications, such as Firefox, Google Chrome, and Opera browsers have all launched browser-based extensions., supports viewing resource information of IPFS nodes. Netflix, the world's largest streaming media platform, has also cooperated with IPFS to integrate peer-to-peer services and other technologies in the IPFS system into Netflix tools, using IPFS technology to accelerate cloud construction, design and testing.

On the other hand, with the launch of 5G and the explosion of short videos, the storage requirements of the entire Internet will further increase. Traditional storage methods can no longer meet the increasing data levels. According to research on the world's second largest market According to the analysis of the agency Markets and Markets, global network data will usher in a 500% growth in 5 years. In 2017, the entire network data was on the order of 40 ZB; in 2022, the data will reach 170-200 ZB. Faced with huge storage needs, IPFS allows us to break through more technical impossibilities.

In general, IPFS, as a new generation of data storage solutions, is very promising. It will make up for the shortcomings of traditional storage methods and bring safer, lower cost, and larger storage space. , but IPFS still has a long way to go before it can be widely used around the world. This is also the direction that many of our distributed storage companies will work hard in the future.

The prospects are very promising, but at present, the main network is real first. The best way for ordinary investors to participate is mining, cloud nodes, not affected by bandwidth, Noah Cloud Mining Pool, Safe, efficient and cost-effective.

Capital is all about profit. Once the Filecoin mainnet is launched, it will definitely be a hot topic, and the first batch of miners will definitely earn good profits.

If you need IPFS mining machines and hosting services, please contact me.

The currency price has exceeded 200U, think about it yourself

4. How to enter the Metaverse

The Metaverse is built by humans using digital technology. A virtual world that mirrors or transcends the real world and can interact with the real world, and a digital living space with a new social system.
From the perspective of time and space, the Metaverse is a digital world that is virtual in the space dimension and real in the time dimension; from the perspective of authenticity, there are both digital replicas of the real world and creations of virtual worlds in the Metaverse From the perspective of independence, the Metaverse is a parallel space that is closely connected to the external real world and highly independent; from the perspective of connectivity, the Metaverse is a sustainable space that includes networks, hardware terminals and users. A virtual reality system with wide coverage.
To be precise, the metaverse is not a new concept. It is more like the rebirth of a classic concept. It is a conceptual embodiment under new technologies such as extended reality (XR), blockchain, cloud computing, and digital twins. change.
The word "Metaverse" is more of a business symbol. It does not itself have any new technology, but integrates a large number of existing technologies.technique.
Parallel to the real world, reaction to the real world, and integration of multiple high technologies are the three major characteristics of the future metaverse. The Metaverse is essentially a process of virtualization and digitization of the real world, which requires a lot of transformation of content production, economic systems, user experience, and physical world content. However, the development of the Metaverse is gradual. It is finally formed by the continuous integration and evolution of many tools and platforms under the support of shared infrastructure, standards and protocols. It provides an immersive experience based on extended reality technology, generates a mirror of the real world based on digital twin technology, builds an economic system based on blockchain technology, closely integrates the virtual world and the real world in the economic system, social system, and identity system, and allows Each user performs content production and world editing.

5. The "Metaverse" is popular, what is this thing?

The Metaverse is linked and created using technological means. A virtual world that maps and interacts with the real world, a digital living space with a new social system. [12]
The Metaverse is essentially a virtualization and digitalization process of the real world, which requires a lot of transformation of content production, economic systems, user experience, and physical world content. However, the development of the Metaverse is gradual. It is finally formed by the continuous integration and evolution of many tools and platforms under the support of shared infrastructure, standards and protocols. [23] It provides an immersive experience based on extended reality technology, generates a mirror of the real world based on digital twin technology, builds an economic system based on blockchain technology, and closely integrates the virtual world and the real world in the economic system, social system, and identity system. , and allows each user to perform content production and world editing. [23]
The term metaverse was born in the 1992 science fiction novel "Snow Crash". The novel depicts a huge virtual reality world where people use digital avatars to control and compete with each other to improve their status. , so far it seems that it still describes an advanced future world. [1] Regarding the "metaverse", the more recognized source of thought is the American mathematician and computer expert Professor Verno Vinci. In his novel "Real Names" published in 1981, he creatively conceived a brain-computer system. Interface to enter and gain sensory experience in the virtual world.

6. Is Spacetime Cloud IPFS reliable?

Is IPFS reliable?
IPFS is a technology that changes people’s lifestyles. It can effectively solve the current data storage dilemma, significantly reduce data storage and transmission costs, and improve data security. IPFS is just a concept and is innocent in itself. Whether it is IPFS technology or IPFS incentive layer FIL, there is nothing right or wrong in itself. It can even be said that it was originally invented to serve mankind.
Let’s see where its roots are and what are its roots? There are nothing more than two, one is technologically advanced and the other is safe and reliable. Let’s talk about IP firstFS technology, IPFS assigns a unique hash value to each file (file fingerprint: created based on the content of the file). Even if the contents of two files differ by only one text, their hash values ​​are different. Therefore, IPFS is based on file content addressing, rather than domain name addressing like the traditional HTTP protocol.
IPFS removes duplicate files from the entire network content and establishes version management for files. This means that each file has a historical record and you can easily return to the historical version of the file for query. When querying a file, search based on the hash value of the file (unique in the entire network). Let’s talk about the advantages of IPFS:
1. Fast download speed. IPFS is a distributed storage protocol system. When downloading relevant data, it will be downloaded from multiple nodes at the same time. Compared with HTTP, it is faster to download from the central server. a lot of.
2. Storage space is cheap. IPFS is a blockchain technology that uses filecoin to encourage resource storage contributors to share their hard drives and remove redundant storage from the entire network, greatly saving network storage space and making IPFS very popular. Cheap.
3. Security, centralized servers are currently difficult to resist DDOS attacks, and IPFS has the ability to resist such attacks, because all access will be dispersed to different nodes, and even the attacker himself is one of the nodes. To some extent, IPFS can even withstand quantum computing attacks.
4. Openness. We all know that Bitcoin is a decentralized and anonymous digital currency. These characteristics make Bitcoin unable to be controlled and transactions cannot be tampered with because IPFS is built on a decentralized distributed network. , so IPFS is difficult to be centrally managed and restricted, and the Internet will be more open.
When we look at a project, we not only have to look at whether its technology is advanced, but also what value its technology can bring in reality and what advantages it has compared to its predecessors. It is not difficult to see that IPFS is not only technologically advanced but also brings application value. IPFS is one of the few reliable projects in the currency circle.
How to participate in ipfs mining?
The way to participate in IPFS mining is to cooperate with high-quality miners. After purchasing a storage server, host your storage equipment in their IDC computer room, sign the purchase contract and hosting contract, and the rest is to purchase the pledge coins yourself. Deposit the GAS fee and GAS fee into the APP account for packaging, and then check the income.

7. Can OKEX contracts be opened long and short at the same time?

There are two different types of long and short contracts.
In the "isolated position" mode: For the same contract, if you open a long position, you can only have a position of 10 times or 20 times; if you open a short position, you can only have a position of 10 times or 20 times. If you have opened a short position contract with 10 times leverage, you can also choose to open a position with 10 times or 20 times leverage for long positions. This means that you can have up to 2 positions under the same contract: -10 (20) times more, Empty -10 (20)times.
For example: For example: 10 times more + 10 short or 20 short, or 20 times more + 10 short or 20 short. In the cross position mode, you can only choose one leverage multiple for each currency. For example, if the BTC contract is opened more than 10 times for the week, it can only be opened 10 times short.

8. What is the core of a smart city? What is the difference between a smart city and informatization? Who has a smart city fooled?

Smart cities. Currently, smart cities around the world have developed from the concept and model stage to the planning and The construction phase is still in the exploratory period. Blockchain is also a hot technology in the exploratory stage, and many people are flocking to it.

Smart cities based on blockchain technology have gradually emerged. In order to meet user needs, Huixin Cloud Platform has hired several product managers in the field of smart cities. In order to accelerate the layout in the field of smart cities, Great progress has been made in financial systems, audit systems, supply chains, energy and power, smart park management systems, smart transportation applications and other fields.

New smart cities are mainly built around big data and blockchain technology. By combining "one center, four platforms, multiple applications, and unified chain", a multi-dimensional smart city solution is formed.

The so-called "one center" is a city-based big data center in various dimensions. The “four platforms” are the smart government comprehensive information service platform, the smart urban management comprehensive information service platform, the smart people’s livelihood comprehensive information service platform, and the smart economy comprehensive information service platform. "Multiple applications" includes various types of smart applications. Finally, the “unified chain” is a trustworthy smart city information ecology based on blockchain.

Based on the presentation of the overall smart city solution, it is analyzed according to four dimensions: perception layer, network layer, platform layer and application layer.

Perception layer: including various Sensors, RFID electronic tags, hardware gateway equipment and Internet equipment for various professional networks. These perception layer hardware mainly support our various networks.

Network layer: This layer is a carrier network that supports communication and data constructed from various hardware devices in the perception layer. Generally speaking, we include three categories: Internet of Things, communication network and Internet.

Platform layer: The platform layer mainly consists of various information platforms built on the carrier network. These information platforms provide basic information services for our subsequent construction of various applications. Common ones include data center platforms, credit reporting center platforms, IT center platforms, etc.

Application layer: The application layer mainly involves all aspects of special services in the smart city component process, such as smart government affairs, smart transportation, smart human society, smart finance, smart security, smart Internet of Things, Intelligent assets, intelligent supply chain, intelligent carbon emissions, etc.

How are smart cities on the blockchain different?

In recent years, local governments and industry giants have made efforts to develop smart cities. The Innovation Energy City is built on the blockchain. How is this different from the past?

Unlike previous smart city projects, the Innovation Energy City does not build on existing urban objects.Instead of adding an "intelligent application layer" to management and IT facilities, infrastructure that supports technologies such as the Internet of Things and blockchain is deployed from the bottom up, starting from the planning and construction stages. The two major characteristics of the innovative energy-gathering city are distributed thinking and open collaboration.

Distributed construction method

Use distributed construction method to build cities. A city is a large and complex system with dense population, business ecology, scenes, and enterprises gathering together. “Blockchain smart cities do not have to have a complete top-level design, and do not have to consider how each part must be done, but will consider in advance how each part will be done. It will be part of the blockchain network. Specifically, blockchain technology should be integrated during design, and the implicit openness of the integration allows for the flow of data between different projects."

A major role of blockchain is It lies in breaking down data silos. However, previous smart city and smart city management projects still encountered the problem of data islands. It may not be possible to connect smart transportation and smart energy systems made by different companies, but the interconnection of different systems can be achieved on the blockchain, and new applications can be built on the interconnected level and continuously improved in practice. Distributed energy storage technology is the need of the future

Prospects of smart cities based on blockchain

A city is a complex comprehensive system with dense population and various scenarios gathered together. It is destined that building a smart city is a systematic project that requires the help of various existing technologies. Blockchain technology is not a disruptive technology, but it reshapes the trust mechanism based on existing Internet, big data, cloud computing and other technologies, so that the network not only realizes the dissemination of information, but also realizes the transfer of value.

The application of blockchain technology in building smart cities, including smart parks, smart Internet of Things and other point-to-point communication mechanisms that use blockchain technology to reduce operating costs, popularize IoT devices, and use its asymmetric encryption Features protect user privacy and reshape trust mechanisms. Smart assets use blockchain technology to digitally prove physical assets, accelerate the circulation of traditional assets, shorten investment cycles, and reduce transaction costs. The smart supply chain enables traceability of food and industrial products and reduces the risk of counterfeit goods. At the same time, it can break information silos, promote upstream and downstream interactions in the supply chain, and reduce time and economic costs.

In addition, blockchain technology has many other applications in the construction process of smart cities, such as smart transportation, e-government, legal applications and other fields, which have broad prospects. With the help of a buzzword in the blockchain field - the future is here but not popular yet, the future of smart cities based on blockchain technology is promising.
