1. What's the difference between the Internet of things, blockchain and big data
in the near future, the number of devices in the Internet of things will explode, which may be hundreds of billions or trillions. If such a huge network is still managed in a centralized networking mode, the infrastructure investment and maintenance of the data center should be incalculable
in essence, big data belongs to a small branch of database, so this problem is attributed to the relationship between big data and database. Database is a very old research field in software, Internet and it. From the initial file system to ER model, to the three achievements of traditional database, which are known to all, relational model, transaction processing and query optimization, to the rise of NoSQL database after the popularity of Internet, database technology is constantly developing and changing, Then it also includes semi-structured data processing represented by XML and unstructured data processing such as text and voice
it seems that the relationship between blockchain and database is actually such a relationship. From the evolution process of database technology, we can find that it always comes from how to meet new business requirements and then create new data processing technologies. For example, from the beginning of the file system, why do we need the ER model? It is because with the development of the financial instry, people have further requirements for these fast accounting, high concurrency data writing and access, which leads to the emergence and rapid development of the entity relationship model. Why did NoSQL database appear later? It is because the rapid development of the Internet puts forward higher requirements for updating the database, so in essence we think that the whole Internet is a big database
things are always developing. Of course, after we solve the problem of massive real-time data processing on the Internet through NoSQL database and cloud storage, the next problem must come, that is, how to solve the authenticity and effectiveness of data in a large-scale way
for example, it may be related to our diet, from the problem of food and clothing at the beginning, to the problem of nutrition structure, and then to the problem of food safety that everyone is concerned about. The development of database is the same. When we can solve these problems of data storage and data access through ER entity relationship model and NoSQL database, Next, we need to care about and solve the problem of authenticity and effectiveness
so at this stage, these technologies, represented by blockchain, must be a new starting point and new requirements for the authenticity, validity, unforgeability and tamper resistance of data compared with the current database. We can clearly feel that the trend of database and blockchain integration is actually very close and irresistible, just like the movie just mentioned, the procers of content begin to develop in the direction of virtual reality and augmented reality; From the perspective of database, blockchain is a new way of data organization. We believe that big data and blockchain are integrated.

2. I don't know when the Internet of things has been deeply related to the blockchain, and it has become more and more intense this year. Whenever the Internet of things is mentioned, blockchain will follow; When it comes to blockchain, we must also bring the Internet of things into the topic. The public can't help but wonder whether the Internet of things rubs the heat of blockchain, or does the blockchain pull the Internet of things hard to block the "bullet"? Now let's explore
the term "Internet of things" is mentioned almost every day in today's life. Some data show that in 2017, there were about 8.4 billion intelligent devices connected to the Internet, such as thermostats, cameras, street lamps and other electronic procts. According to foreign McKinsey & company data, this number may reach 25 billion by 2025, and the scale of the whole economy will reach 6 trillion US dollars
are you dazzled by such a huge number? Although the Internet of things technology has been widely used all over the world, its defects are graally highlighted
according to the traditional mode, the data center (server) of the equipment manufacturer often collects the information of all connected devices, which determines that the server needs to have strong operation and storage capacity. Moreover, with the geometric growth of Internet of things equipment, the cost of server maintenance will also increase greatly, which makes it difficult for small and medium-sized enterprises to maintain
at the same time, in terms of communication compatibility, the global Internet of things platforms are lack of a unified language, which is easy to cause communication obstacles between multiple Internet of things devices. This is e to the obvious fragmentation of the Internet of things instry, whether it is smart home, smart home appliances, robots, smart cars, etc., the networks they connect are fragmented and closed. In addition, the status quo of the Internet of things instry is still full of mountains, and their influence is relatively limited, so it is difficult to reach a unified standard in a short time
based on this, the standard chain team, after accumulating the previous experience from the Internet of things, combined with the characteristics of blockchain, proposed the concept of Internet of things

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. The blockchain system must be applied to the blockchain technology, but now some of the digital currencies connected to the blockchain are also known as the blockchain system, which needs to be studied; It has the characteristics of blockchain technology, that is, decentralization, irreversibility, distributed storage, transparency and openness; Shengshi Huacai is very professional in blockchain, which is worth recommending
5. There is no essential difference between the two majors. The content of Internet learning is more general, and the content of Internet of things learning is more specialized (involving sensors, wireless networking, etc.). In fact, the protocol for truly realizing interconnection is the same
