blockchain
In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner according to time sequence, and cryptographically guarantees a distributed ledger that cannot be tampered with and cannot be forged.
Broadly speaking, blockchain technology is to use block chain data structure to verify and store data, use distributed node consensus algorithm to generate and update data, use cryptography to ensure the security of transmission and access, and use automated script code. A distributed infrastructure composed of smart contracts to program and manipulate data.
I have looked at the articles on the Internet, and there are roughly three categories. One is the opinions and opinions of people with technical backgrounds, the other is the opinions of the investment community and stakeholders, and the third is the cacophony of people who eat melons. . I mainly just look at the opinions of big names with technical backgrounds. Blockchain is just a technology, and the focus is on application scenarios. Stakeholders are mainly kidnapped and fooled by interests. The melon-eating crowd followed and booed blindly.
artificial intelligence
The core is to use linear algebra, probability theory and mathematical statistics to do some work, and make predictions based on some existing data.
Internet of Things
The Internet of Things is the application expansion of the Internet. The data of the Internet is put up by people, and the data of the Internet of Things is automatically collected by sensors. Technically, it is divided into perception layer, network layer and application layer.
cloud computing
It is the application of supercomputers in general fields, which concentrates computer resources through the construction of computer rooms. Supercomputer is the industry's best technology. Cloud computing is general system integration, mainly driven by business. For ordinary users, it saves costs. For related operators, it also saves costs. Inside, some are built in the bomb shelter, and some are built under the lake.
Big Data
Some "bricks" , those who study phenomena, engage in propaganda, talk about a few Vs of big data , and how many Ps are there , these things are useless to operators and ordinary users. For ordinary users, "run at most once" is useful. For commercial operations and practical applications, there are mainly three aspects: relevance, completeness, and multi-dimensionality. Correlation is to downplay the causal connection. These are aimed at operators. For individuals, the causal connection is still the most important connection. ". Doing good deeds and being a good person is more important than anything else.
