1. What is the Internet of things

in fact, in a simple way, big data is to assist decision-making by analyzing and mining a full amount of non sampling data

the characteristics of big data

big data refers to the massive, high growth rate and diversified information capital that needs new data processing mode to collect, store, manage and analyze its content for the purpose of serving decision-making

big data has the following essential characteristics:

1. The fundamental purpose is to serve decision-making. Big data can help all kinds of organizations and indivials greatly improve their decision-making ability and make better decisions and judgments

Big data usually refers to the amount of data above 100t, which is difficult to be calculated effectively by traditional calculation methods, but must rely on new calculation methods and data mining tools

3. High frequency, big data is the data generated by user participation and interaction, according to the user's network traces to timely understand the user's relevant data, this kind of data is high-frequency data calculated by day or even hour. But the traditional data frequency is very low, many data are calculated by month or even by year

Big data is real-time data and can react in real time. For example, entering a keyword in the web search box can instantly present it, while the traditional data collection method is seriously lagging behind

5. Always online. Online is the precondition of big data. From this point of view, big data is always online and can be called at any time. By analyzing the traces of users on various network terminals, big data can better analyze users' behaviors, emotions, thoughts, hobbies and needs, so as to make better decisions and analysis

three key points of big data

first, the availability of data. At present, in China, the development of big data is seriously constrained by the lack of publicity of government information, a lot of data is difficult to obtain, leading to the difficulty of real big data mining and analysis, which requires the government to open more data in time to improve the availability of data

Secondly, the scientific model construction. The scientific nature of the model directly determines the quality of data analysis, which requires a high level of modeling, of course, the more data is concive to the reasonable construction of the model

Third, use experts to refine opinions. The original and high-quality viewpoint based on data mining, which provides the basis for decision-making, highly relies on high-quality data interpretation, which reflects the value of instry experts

2. Before the "Internet of things" - billions of years ago, everyday things like refrigerators, bars and lawn sprinklers were silent. According to a recent report entitled "device democracy" from IBM, it is impossible to track and manage these billions of dollars of devices in a centralized way, and such an attempt is not wise; This kind of attempt will make them vulnerable to hackers and government supervision. Distributed registers seem to be a good choice
the Internet of things uses blockchain as a communication bridge between things. In order to achieve this, we can use
the programmability provided by Ethereum, which is not only to let people's property be tracked and registered. It has some new uses. Under various methods and rules, Ethereum blockchain embedded in the car key can be sold or rented to generate a new P2P for renting or sharing cars. Further, some people talk about the application of this technology to make self driving cars a social public resource. Under pre-set proceral rules, such vehicles can store their own digital money to pay for them from renting fuel, repairs and parking spaces.

3. The analysis of Chongqing jinwowo is as follows:
blockchain can also be naturally combined in the field of Internet of things and logistics
through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management
this field is considered as a promising application direction of blockchain.

4. I don't quite understand what cheap means:
first, because the US dollar is relatively "valuable", for example, the current US dollar = 6.6155 yuan, so the base is small when converting bitcoin
Second, there is a price difference between Chinese and foreign bitcoin exchanges, for example, the price of the US exchange is generally 1% - 2% lower than that of China, and even 9% more often, plus the transaction and withdrawal fees, It will also lose part of the value of the currency
because domestic people invest more in bitcoin, and bitcoin is fixed and limited, it is inevitable that the price of bitcoin is high. This does not rule out that makers are pushing up the price. The number of users and trading volume of each exchange are different. The price of bitcoin is caused by many factors, especially for countries with foreign exchange control, The price difference between China and foreign countries will be relatively high--- Wan foreign exchange assistant

5. The application of blockchain in the Internet of things can mainly solve the following problems: solving security risks and protecting user privacy; Rece the operating costs of the Internet of things
in fact, there are many specific applications, but they are all in the process of development and research and development. It can be said that the blockchain technology is not mature. Among many enterprises, Yingtang Zhongchuang has more development and application of blockchain technology, which has a certain impact on the future development of the Internet of things.

6. Take some application scenarios for example: you can intuitively understand smart home, Internet of vehicles, smart grid and new energy vehicles. You can pay attention to SMIC blockchain service platform for real-time understanding of more wonderful application problems
