Specific application of Internet of things plus block chain

1. First of all, we need to know exactly what both are before we can combine them

blockchain, which appeared in front of you when bitcoin was born a few years ago, is essentially a distributed data account book. We can see blockchain technology as an underlying code system in the Internet, which is decentralized, open, transparent, anonymous, user-friendly and user-friendly It can't be tampered with. Blockchain basically solves most of the trust problems in the weak trust environment, and has a wide range of applications. It can be combined with almost all fields, and even change the proction relationship of our three proction factors
the Internet of things, literally means "the network connecting things", its core is actually based on the data communication between the Internet and offline sensor devices. The Internet of things can be said to be the proct of the Internet extending offline. If the previous Internet era is a pure online information era, then the Internet of things will bring a new network era of Online + offline combination. All things are interconnected, which will greatly change our proction and life, improve and improve proctivity
then, how can blockchain and Internet of things be combined? Maybe there are different application scenarios in different instries. Recently, I saw a technology company called chaincmop chain computing, which has a smart farming management scheme that uses IOT equipment to monitor farm conditions + blockchain system in agricultural breeding, which is very enlightening. For example, in the future, you can use the Internet of things devices to detect the temperature, humidity and seed status of granary seeds in an all-round way, and these data can be synchronized and encrypted by using the distributed and encrypted features of the blockchain, so that the monitoring data can be more efficiently transmitted to each node, and the monitoring data can be well protected, To avoid tampering in the process of transmission.

2. In the future, jinwowo group will focus on promoting the legal circulation and commercial application of big data with blockchain technology
today's very popular blockchain technology can establish low-cost connections between devices in the Internet of things, and also improve the security and privacy of the system through decentralized consensus mechanism
at the same time, the superposition of blockchain technology and smart contract can turn the internal devices into self maintenance and self-regulation network nodes, which can exchange information, verify identity and trade with strangers on the basis of pre-defined.

3. 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.

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
