1. With the development and integration of artificial intelligence, big data and computing power, the three have been organically integrated into an intelligent whole. Its connotation and denotation tend to be diversified, and the applications in various subdivision fields are also rich and superimposed. You have me and I have you. The difference and boundary between artificial intelligence, big data and computing power are more and more blurred
at this stage, the application of artificial intelligence and big data has penetrated into various fields such as instry, agriculture, medicine, national defense, economy, ecation and so on, and the commercial and social value generated is almost unlimited. With the development of artificial intelligence and Internet of things, cloud computing is no longer limited to storage and computing, and has become an important driving force for the development and transformation of various instries. You can learn more about AI, big data and computing power on the 10th power computing power platform.

2. With the emergence of blockchain technology, although we have taken many steps towards this futuristic vision, we are still far from achieving the ideal goal. Some key limitations are listed as follows:
1. Lack of mainstream blockchain network specially developed for IOT devices (Note: as of the time of writing, no blockchain system can be called "mainstream")
2. The device manufacturer has not yet embedded the encryption key into all hardware, nor established the compatibility with blockchain as a general standard
3. The software encryption method used to guarantee the privacy protection algorithm is extremely inefficient and impractical [1], while the hardware solution needs to be based on the complete trust of the manufacturer and the whole manufacturing supply chain. Therefore, it is difficult to prevent data piracy
4. Artificial intelligence is not precise enough to realize this highly autonomous decision-making behavior in equipment
5. In order to further eliminate the risk of transaction on the chain, it is necessary to establish the corresponding legal means, but only a limited number of countries and regions [2] recognize that the on chain smart contract has the same legal binding force as the off chain contract
but even if there are these limitations, blockchain still has the potential to provide a wide range of value-added applications, which can solve many of the technology problems faced by the Internet of things. First of all, let's have a deeper understanding of the current progress of blockchain technology and what we can do to improve the existing technology
blockchain network developed for IOT devices
considering all the synergy between blockchain and IOT, what characteristics will a blockchain network that can perfectly meet the needs of IOT have? Although many blockchain technologies are fundamental in nature and will not focus on specific applications obviously, at the level of public ledger, there are many design and optimization choices that can reflect the application stack considered by designers in the development process
the characteristics of IOT devices and their impact on the design of blockchain network
when talking about the IOT, especially when comparing it with the nodes running on the existing blockchain network, we need to be clear: at present, all blockchain networks rely on powerful and always connected servers to perform all record preservation and consensus tasks. At present, it is obvious that the limited and unique characteristics of most Internet of things devices, or even smaller, sometimes mobile devices, are not suitable for the above situation<
"IOT" is basically used to refer to any device connected to the Internet. We can make some summary statements on the characteristics of these devices:
large scale: [3] according to some statistics, the number of IOT devices has exceeded the world population and will continue to grow at a faster speed
limited computing power: [4] even compared with the processing power of ordinary laptops, the computing power of Internet of things devices is often not ranked in the order of magnitude
limited storage space: the original intention of most IOT devices is not to store information locally, but to simply relay information (such as uploading to the cloud), so their storage space is very limited
limited bandwidth and network connectivity: many IOT devices operate in the wild environment without reliable network connection, and the networking cost is high (for example, satellite network deep in the forest)
energy consumption limit: many IOT devices use batteries or operate through energy collection mechanism, which seriously limits their energy consumption
What are the key indicators that need to be met to design a blockchain network that is most suitable for IOT devices
1. The network needs to be scalable: considering that there may be billions of devices connected to any specific blockchain network, the network must be able to expand its ability to process transactions and requests
2. The network needs to support the discovery and transaction of general assets: there are many tradable digital assets and resources (such as data) on the Internet of things devices, not just currency. So there is also a need to find ways to access these assets
3. The network needs to support selective storage: considering all the limitations of IOT devices, they can only participate in a small subset of the network, and the content stored and processed by each device must be carefully selected
4. The network can not only rely on "work" to maintain security: network security can not be simply based on solving complex password problems, which will make it difficult for IOT devices to perform blockchain transactions
5. The network needs to support the de trusted light node: the current IOT devices are not enough to support the operation of the whole node, but they still need to maintain their independence on the blockchain network, so the "light" node running on the IOT devices can not be too naive (that is, blindly trust another whole node), And there should be a way to verify the network state and state transition
6. The network needs to support point-to-point transactions: many transactions between IOT devices are highly localized, that is, devices are adjacent to each other, and it is impossible to wait for the delay caused by the whole network verification every time
to sum up, even though there are still many limitations in the combination of blockchain and Internet of things, on the basis of meeting the above key indicators, we can design the blockchain network which is most suitable for Internet of things devices, so as to better enable the ecology of Internet of things.

The disadvantages of the Internet of things are:
1. Security: the Internet of things systems are interconnected and communicate through the network. Despite any security measures taken, the system hardly provides any control, and can trigger a variety of network attacks
2. Privacy: the Internet of things system can provide the most detailed personal data even if it does not actively participate in users
Complexity: it is quite complex to design, develop, maintain and support large-scale technology to Internet of things system 
the advantages of the Internet of things:
1. Efficient resource utilization: if you understand the function and working mode of each device, you can improve the effective utilization of resources and monitor natural resources
2. Minimize manpower: when IOT devices interact with each other and communicate with each other and complete a large number of tasks, they can minimize manpower
Save time: because it reces manpower, it definitely saves time. Time is the main factor that can be saved through the Internet of things platform4. Enhance data collection: network and collect relevant data
5, improve security: the system can connect all these contents, then it can make the system more secure and efficient
4. Cloud computing big data of Internet of things. Cloud computing refers to the delivery and use mode of IT infrastructure. It refers to obtaining the required resources (hardware, platform, software) on demand and easy to expand through the network. The network that provides resources is called "cloud"“ In the view of users, the resources in "cloud" can be expanded infinitely, and can be obtained at any time, used on demand, expanded at any time, and paid by use. This feature is often referred to as using it infrastructure like hydropower. Cloud computing in a broad sense refers to the mode of service delivery and use, which means to obtain the required services on demand and easy to expand through the network. This kind of service can be it and software, Internet related, or any other service
2. Internet of things
simple understanding: the Internet of things, that is, the Internet of things. Internet of things is also known as sensor network in the world, which is another wave of information instry after computer, Internet and mobile communication network. Everything in the world, from watches and keys to cars and buildings, can be "automatically spoken" as long as a micro sensor chip is embedded to make it intelligent. With the help of wireless network technology, people can "talk" with objects and "communicate" between objects, which is the Internet of things. With the development of information technology, the application of Internet of things is growing. Such as: intelligent transportation, environmental protection, government work, public safety, safe home, intelligent fire control, instrial monitoring, elderly care, personal health, flower cultivation, water system monitoring, food traceability, etc. The big ideal is the smart earth. At present, the smart cities existing in real life and under construction are the concept of Internet of things
3. Big data
big data is the proct of real data aggregation with many kinds, large flow, large capacity, high value and fast processing and analysis speed. Big data, or massive data or massive data resources, refers to the information that is too large to be captured, managed, processed and sorted in a reasonable time by current mainstream software tools to help enterprises make more positive decisions
4V features of big data: volume, velocity, variety and veracity
that is: volume, diversity, velocity and veracity
4. The relationship between big data, cloud computing, Internet of things and mobile Internet
the Internet of things corresponds to the sensory and motor nervous system of the Internet. Cloud computing is the collection of the core hardware layer and core software layer of the Internet, and it is also the sprout of the Internet central nervous system. Big data represents the information layer (data ocean) of the Internet and is the basis of Internet wisdom and awareness. Including the Internet of things, the traditional Internet, mobile Internet in a steady stream to the Internet big data layer to gather data and receive data. Cloud computing and Internet of things promote the development of big data.

5. The concept of Internet of things was put forward in 1999. The Internet of things is "the Internet of things", its English name is Internet of things. This has two meanings: first, the core and foundation of the Internet of things is still the Internet, which is an extended network based on the Internet; Secondly, its client extends to any item to exchange information and communicate with each other. Therefore, the definition of the Internet of things is a kind of network that connects any item with the Internet according to the agreed protocol through radio frequency identification (RFID), infrared sensors, global positioning system, laser scanners and other information sensing devices to exchange and communicate information, so as to realize the intelligent identification, positioning, tracking, monitoring and management of items. The Internet of things is known as the third wave of the development of the world information instry after the computer and the Internet. It is the application expansion of the Internet. It is not so much the Internet of things as the business and application based on the Internet.
6. The Internet of things is an important part of the new generation of information technology, and also an important development stage of the "information" era. Its English name is "Internet of things (IOT)". As the name suggests, the Internet of things is the Internet of things. This has two meanings: first, the core and foundation of the Internet of things is still the Internet, which is an extension and expansion network based on the Internet; Second, its client extends to any goods and goods, information exchange and communication, that is, mutual information. The Internet of things is widely used in the integration of networks through intelligent sensing, identification technology and pervasive computing and other communication sensing technologies, which is also known as the third wave of the development of the world information instry after the computer and Internet. The Internet of things is the application development of the Internet. It is not so much a network as a business and application. Therefore, application innovation is the core of the development of the Internet of things, and Innovation 2.0 with user experience as the core is the soul of the development of the Internet of things.
