the digital gold of the future: PI. Mobile phone free dig
the development of the project is divided into four stages:
the first stage is the simulator stage, which is a period of high output and high rate of the whole project. The mining speed is the fastest and the output is the highest. At this stage, KYC (real name authentication) scheme will be tested
this phase will start on March 14, 2019, run for about a year, and will end at the end of March 2020< br />< The above is done & gt
the second stage is the test network stage. In the early stage of this stage, KYC (real name authentication) will be opened in a large range, and applications will be put on the shelves and test nodes will be launched; Later will test the main network, wallet, etc
this phase will start at the end of March 2020 and run for half a year to one year< br />< The above is in progress & gt
the third stage is the main network stage. In this stage, every miner will have his own wallet address, and the PI in his hand can be exchanged freely. Only at this time can PI have real value and price, and you can use pi to shop and exchange for legal money
this stage is expected to start in the second half of 2020 or 2021. In the first half of the year, there will be exchanges online
the fourth stage is after the main network. After the main network, the whole system will no longer be interfered and controlled by the project party or non project party, and will run freely and spontaneously. The specific development situation is immeasurable, which may be tens of millions, hundreds of millions, or even billions of user groups
if you want to see the whole picture of this project, it is estimated that it will take at least three years, that is, 2021
as long as you are patient and ambitious, let's witness together and look forward to your joining!
The most strategic resource of a city is data. The essence of smart city governance should be data sharing and network collaboration. It is reported that Hangzhou, where Alibaba headquarters is located, has opened up 9 networks and more than 50 business systems, and has rapidly integrated nearly 1000pb of data such as Internet traffic data, traffic equipment detection data, government department data and camera video, adding about 12pb a day, more than 80% of which are real-time data. In 2019, urban real-time simulation technology will be in full swing, and more cities will use algorithms to automatically monitor real-time data and analyze the status of all systems in the city in real time
on January 2, the official website of Alibaba Dharma Institute released the top ten technology trends in 2019: Intelligent City, voice AI, AI chip, deep learning, computing system reconstruction, 5g, digital identity, automatic driving, blockchain and data security. Smart city based on urban real-time simulation technology is regarded as the first technology trend in 2019
although the city's intelligent devices are more and more advanced, city managers can't see the city we live in at a glance, it's difficult to deeply understand the real needs of the city's "data ocean" under the water surface, and they can't make efficient decisions in time to make the city operate efficiently
The popularity of "new infrastructure" has been high since the beginning of the year
A few days ago, the Standing Committee of the Political Bureau of the CPC Central Committee held a meeting to clearly emphasize the need to "speed up the construction of 5g network, data center and other new infrastructure". At the same time, local governments have come down one after another, not only listing "new infrastructure" as a key investment plan in 2020, but also investing as much as 40 trillion yuan As a result, the concept of "new infrastructure" (short for new infrastructure construction) is once again on top of the tuyere because of the active deployment of the central and local governmentswhat is "new infrastructure"
different from the "old infrastructure" proposed in 2008, that is, the well-known "tiegongji" (railway, highway, airport, port, water conservancy, etc.), the "new infrastructure" focuses more on highlighting the new direction of instrial transformation and upgrading, reflecting the general trend of accelerating the development of high-end instry, which generally refers to 5g infrastructure, UHV, intercity high-speed railway and urban rail transit New energy vehicle charging pile, big data center, artificial intelligence and instrial Internet
, some traditional instries were hit. The central government focused on the new infrastructure and gave a "reassurance" to the weak economy on the one hand. On the other hand, it also pressed the "accelerator" to the development of the instrial Internet. p>
as the pillar instries of the national economy, automobile and travel have also become the focus of "new infrastructure". As early as before the concept of "new infrastructure" was put forward, bat and other leading technology enterprises had sensed the opportunity and seized the opportunity to enter the automotive instry one after another. Take Tencent for example, although it is not the first one to enter the game, it has already formed its own style of play in the fields of Internet of vehicles, automatic driving 5g vehicle road collaboration, etc
5g -- the key to "new infrastructure construction"
let's talk about 5g first
in the "new infrastructure", 5g is listed as the key "new infrastructure" supporting the digital, networked and intelligent transformation of economy and society, which plays a very important role in the construction of intelligent vehicles, intelligent transportation and smart city facilities
now the focus of deploying 5g is to promote the commercial use of 5g
in February this year, China's 11 ministries and commissions jointly issued the "intelligent vehicle innovation and development strategy", which clearly pointed out that 5g business deployment should be combined to promote the collaborative construction of 5g and the Internet of vehicles. The acceleration of 5g commercial speed can bring huge imagination for the development of automobile instry, especially in the field of vehicle road collaboration, which will be the most important battlefield of 5g commercial
in this invisible battlefield, Tencent took the lead and established the future network laboratory, the first 5g technology and application research team in Chinese Internet companies. In May last year, Tencent future network laboratory officially released 5g open source platform for vehicle road collaboration, focusing on the field of vehicle road collaboration based on edge computing, connecting people, vehicles, roads and cloud, and focusing on solving the instry pain points such as low penetration rate of terminal equipment, lack of mainstream software to reach users, lack of effective connection of road equipment, and fragmentation of road information
at present, Tencent future network laboratory has reached cooperation with Highway Research Institute of the Ministry of communications, National Engineering Laboratory of urban rail transit green and safety construction technology, as well as Intel, Nokia, China Unicom, Neusoft and other enterprises to jointly promote the rapid landing of intelligent networked vehicle applications in 5g era
Internet of vehicles - the "leading geese" of 5g application landing
5g commercial application, we have to mention the Internet of vehicles
in the instry, some people compare the Internet of vehicles to the "leading geese" of 5g, a "key new infrastructure" application. Driven by the three factors of policy, instrial chain and 5g business, it is expected to usher in a comprehensive outbreak from next year. For car companies, if they want to quickly realize digital evolution, the primary task now is to take the lead in the competition of Internet of vehicles
therefore, automobile enterprises also began to actively cooperate with Internet technology enterprises, and in the cooperation, Internet enterprises also have their own clear positioning. Zhong Xuedan, vice president of Tencent smart travel, has repeatedly stressed that Tencent does not touch the hardware or the operating system. It creates the scene and experience of the car on the upper level, connects with the Internet Ecology, and helps the car enterprises connect with users. Based on such a "linker" positioning, what has Tencent done
Tencent's Internet of vehicles layout has been formally launched from the concept. Through Tencent's latest Tai ecological Internet of vehicles, car owners can experience wechat car version and other applications specially designed for driving scenes. While recing the use of mobile phones, they can interact with the real world safely and naturally, and get a seamless experience of getting through the scenes before, ring and after getting on the car. At present, Tencent has cooperated with GAC, Chang'an, great wall, Dongfeng Liuqi and other self owned brands in the aspect of Internet of vehicles, and is also exploring cooperation with BMW and other international brands
In the new infrastructure, 5g, artificial intelligence and big data are widely used in automatic drivingand recently, the action of automatic driving is more frequent in our country. First, the Ministry of instry and information technology, the national development and Reform Commission and other 11 ministries and commissions issued the "intelligent vehicle innovation and development strategy", which specially deployed the work related to automatic driving; Recently, the Ministry of instry and commerce also issued the recommended national standards for vehicle driving automation classification and approval. The first time the classification standard of China's automatic driving vehicle was formulated, and the driving automation was divided into 0 to 5 levels. p>
as early as many years ago, people from all walks of life have paid much attention to automatic driving. With the efforts of the government, the automobile instry and the Internet instry, great breakthroughs have been made in laws and regulations related to automatic driving, high-precision maps, radar technology, 5g / v2x, road testing, etc
in China, Tencent's autopilot team has not only built a high-precision map platform, data cloud platform and simulation platform integrating autopilot R & D, testing, evaluation and verification, but also integrated a complete chain of autopilot technical solutions and inclusive, innovative and sustainable smart city solutions, Assist the development and test of automatic driving, assist the formulation and verification of relevant standards
at present, Tencent automatic driving has joined hands with the national intelligent network automobile (Changsha) test area to build Hunan Province & quot; Intelligent networked Vehicle Simulation Laboratory & quot; The project is dedicated to the realization of safe and efficient intelligent vehicle experiment in the simulation environment. In addition, through the strategic cooperation with BMW China, Tencent is also helping BMW to establish a high-performance data development platform and accelerate BMW's research and development of automatic driving in the Chinese market
at present, the "new infrastructure" policy launched by the state will have a very significant and positive impact on the development of automobile instry and even the construction of smart city in the future. For the "new infrastructure" builders like Tencent, the central government's frequent focus on "new infrastructure" not only brings policy dividends, but also encourages their determination to build. I believe that under the guidance of new policies and new technologies, China's automobile instry will soon embark on the fast track of high-quality development

As a whole, the development of big data in China is still in its infancy. Although the development pattern has basically taken shape, there are many challenges in data open sharing, core technology breakthrough, big data driven development and so on, which need a large number of big data professionals
at present, the development of big data is entering a critical period from concept promotion to application landing. It is very important and necessary to scientifically understand big data and enhance the ability to grasp the development law of big data
big data has good employment prospects. At present, the medical instry, energy instry, communication instry, retail instry, financial instry, sports instry and other instries can generate huge economic value from its data collection, transmission, storage, analysis and other links
learning big data can do a lot of work
for example: Hadoop R & D Engineer, big data R & D Engineer, big data analysis engineer, database engineer, Hadoop operation and maintenance engineer, big data operation and maintenance engineer, Java Big Data Engineer, spark engineer and so on are all jobs we can do! Different positions, the technical knowledge is not the same, need to learn from all directions, one by one break
similarly, the "2016 big data implementation survey" from newvantage partners found that 62.5% of enterprises now have at least one big data project in use, and only 5.4% of enterprises have no plans or implementation of big data projects
researchers said that the adoption of big data technology will not slow down soon. According to the forecast of IDC, the big data and business analysis market will grow from $130.1 billion in 2018 to more than $2030 billion in 2020
"the availability of data, new generation technology and the cultural transformation to data-driven decision-making will continue to drive the demand of enterprises for big data and analysis technology and services." Dan vesset, vice president of IDC's analysis and information management group, said, "in 2015, the global big data market revenue reached $122 billion, and the market revenue increased by 11.3% in 2016. It is expected that the compound annual growth rate of big data market revenue will reach 11.7% by 2020."
although the big data market will grow, enterprises are not so clear about how to use their big data. New big data technologies are entering the market, and the use of some old technologies is also growing
the following are the two major development directions of big data applications in the future< br />
<
01 Internet of things
Internet of things is an important part of the new generation of information technology, and also an important development stage in the "information" era
its English name is "Internet of things (IOT)". As the name suggests, the Internet of things is the Internet of things
it was put forward in 1999: through radio frequency identification (RFID) (RFID + Internet), infrared sensors, global positioning system, laser scanner, gas sensors and other information sensing devices, according to the agreed protocol, any article can be connected to the Internet for information exchange and communication, so as to realize intelligent identification, positioning, tracking, tracking, tracking, etc A network for monitoring and management< The Internet of things has a wide range of uses, including intelligent transportation, environmental protection, government work, public safety, safe home, intelligent fire protection, instrial monitoring, environmental monitoring, street lighting control, landscape lighting control, building lighting control, square lighting control, elderly care, personal health, flower cultivation, water system monitoring, food traceability, environmental monitoring, etc Enemy intelligence investigation and intelligence collection<
02 smart city
smart city (English: smart city) refers to the use of various information technologies or innovative ideas to integrate the constituent systems and services of a city, so as to improve the efficiency of resource utilization, optimize urban management and services, and improve the quality of life of citizens<
the specific definition of smart city is relatively extensive. At present, the definition widely accepted internationally is that smart city is a city form supported by a new generation of information technology and under the environment of the next generation of innovation (Innovation 2.0) in the knowledge society. It emphasizes that smart city is not only the application of new generation of information technology such as Internet of things and cloud computing, More importantly, through the application of Innovation 2.0 methodology oriented to knowledge society, we can build a sustainable innovation ecology characterized by user innovation, open innovation, mass innovation and collaborative innovation
scope of use
uses are divided into ten smart systems, namely: smart logistics system, smart manufacturing system, smart trade system, smart energy application system, smart public service, smart social management system, smart transportation system, smart health insurance system, smart home service system, and smart cultural service system.
