Smart city blockchain Technology

1. blockchain is also a kind of technology, just like mobile Internet technology, it can realize smart city, and there are many special characteristics. Blockchain application is very hot now. There is a SMIC blockchain service platform project initiated by Changsha high tech Zone, which is blockchain + public service mode, and enterprises are being recruited to join the chain.

2. Talk about my understanding. Blockchain and the Internet of things are very hot now. There are many articles about trends. Yesterday, I reviewed the articles a few years ago, and some of them grasped the trends very well. To get back to business, I personally think it's a process from point, line, surface to three-dimensional. No matter the blockchain or the Internet of things, they connect things that were not closely related in the past through technological innovation, and become a whole of mutual connection and interaction. Connecting to the whole, you can do whatever you want. I hope it will help you.

3. Virtual reality game, English name "virtual reality game", as long as you turn on the computer and put on the virtual reality helmet, you can enter an interactive virtual scene, not only the current scene, but also the past and future. Understanding the virtual reality, the concept of virtual reality game is not difficult to understand, put on the virtual reality helmet, you see the world of the game, no matter how you turn your eyes, you are in the game.

Smart city, the global smart city from the concept and model stage to the planning and construction stage, is still in the exploration period. Blockchain is also a tuyere technology in the exploration stage, and many people flock to it

the smart city based on blockchain technology has graally emerged. In order to meet the needs of users, Huixin cloud platform has settled in several proct managers in the field of smart city. In order to speed up the layout in the field of smart city, Huixin cloud platform has established a number of procts in the fields of financial system, audit system, supply chain, energy and power, and smart park management system, Great progress has been made in the application of intelligent transportation

the new smart city is mainly built around big data and blockchain technology. Through the combination of "one center, four platforms, multiple applications and unified chain", a multi-dimensional smart city solution is formed

the so-called "one center" is a big data center based on various dimensions of the city“ "Four platforms" are intelligent government affairs integrated information service platform, intelligent urban management integrated information service platform, intelligent people's livelihood integrated information service platform and intelligent economy integrated information service platform“ "Multi application" includes all kinds of intelligent applications. Finally, the "unified chain" is a trusted smart city information ecology based on blockchain

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

perception layer: including hardware gateway devices and Internet devices made up of various sensors, RFID tags and networks. These sensing layer hardware mainly support our various networks

network layer: this layer is a carrier network supporting communication and data from various hardware devices of the perception layer. Generally speaking, we include three categories: Internet of things, communication network and Internet

platform layer: the platform layer is mainly through various information platforms built on the carrier network. These information platforms provide basic information services for our subsequent component applications. Common such as data center platform, credit center platform, it center platform and so on

application layer: the application layer is mainly involved in all aspects of special services in the process of smart city components, such as smart government, smart transportation, smart human society, smart finance, smart security, smart Internet of things, smart assets, smart supply chain and smart carbon emissions

what is the difference between smart cities on blockchain

in recent years, local governments and instry giants have made efforts to build smart cities. Innovative energy gathering city is built on the blockchain. What is the difference from the past

different from previous smart city projects, innovative energy gathering city does not add an "intelligent application level" to the existing urban physical and it facilities, but starts from the planning and construction stage, and deploys infrastructure supporting Internet of things, block chain and other technologies from the bottom. The two characteristics of innovative energy gathering city are distributed thinking and open cooperation

distributed construction mode

use distributed construction mode to build city. The city is a complex large system with dense population, business ecology, scenes and enterprises gathering. "The blockchain smart city does not need to have a complete top-level design, and does not need to consider how each part must be done. It only considers in advance that each part will be a part of the blockchain network, and specifically integrates the blockchain technology in the design, The implicit openness of integration allows data flow between different projects. "

A major role of

blockchain is to break the data island. In the past, smart city and smart city management projects still encounter the problem of data island. It may not be able to connect the smart transportation and smart energy systems made by different companies, but it can realize the interconnection of different systems on the blockchain, and build new applications at the level of getting through, so as to continuously improve in practice. Distributed energy storage technology is the future demand

prospect of smart city based on blockchain

City is a complex integrated system with dense population and various scenes gathered together, which determines that the construction of smart city is a system engineering and needs to be built with the help of various existing technologies. Blockchain technology is not a disruptive technology, but based on the existing Internet, big data, cloud computing and other technologies to reshape the trust mechanism, so that the network not only realizes the dissemination of information, but also realizes the transfer of value

the application of blockchain technology in the construction of smart city includes smart Park, smart Internet of things, etc. Smart assets, the use of blockchain technology for digital proof of physical assets, accelerate the circulation speed of traditional assets, shorten the investment cycle, rece transaction costs and so on. Smart supply chain can trace the source of food and instrial procts and rece the risk of counterfeit goods. At the same time, it can break the information island, promote the interaction between the upstream and downstream of the supply chain, and rece the time and economic costs

in addition, there are many other applications of blockchain technology in the process of smart city construction, such as smart transportation, e-government, legal application and other fields, which have broad prospects. With the help of a popular saying in the field of blockchain - the future has come, but it is not yet popular. The future of smart city based on blockchain technology can be expected

5. No, bitcoin is tens of thousands of RMB each

6. As an emerging technology, blockchain has great potential in many fields of new smart city. In terms of infrastructure, the application of blockchain technology can explore the efficient exchange of data and information between information infrastructure devices, and enhance the collaborative ability of information infrastructure. In terms of data resources, it is expected to break the original barriers of data circulation and sharing and provide high-quality data sharing guarantee with the help of the characteristics of the blockchain's own data that can not be tampered with and traceable. In terms of intelligent applications, relying on the more reliable cooperation environment provided by the blockchain, a number of bright applications such as "just run once", "data multi run", "accurate service" have emerged
