Although everyone needs their own efforts to acquire wealth, they should also combine the development of the times and never work hard. In the end, they found themselves in the national army for 49 years. So sometimes look up at the world and you may find your own opportunity.
Many people have heard of the words bitcoin, blockchain technology, centralization and decentralization, and the country is also vigorously promoting the development of blockchain technology.
If you want to understand blockchain, you must first understand what decentralization is.
Baidu Encyclopedia is introduced like this:
I believe many people are confused when they see this introduction. What is a node? What is a high degree of autonomy? What is structure? What is nonlinear causality?
Next, I will introduce my understanding of decentralization with the simplest example.
Let's talk about centralization first. A very simple example of centralization is the bank. Whether you deposit money or withdraw money, you must go through the bank. The bank is our centralized institution for depositing and withdrawing money.
Similarly, when we shop online, buyers and sellers shop through Taobao, and then conduct currency transactions through Alipay. As a third-party payment platform, Alipay is also a centralized institution.
Decentralization means that I don't want banks or third-party payment platforms, and I trade directly with sellers.
Why do you want to decentralize?
The biggest advantage of decentralization is to save transaction costs.
Before shopping through Taobao and Alipay, your ID card information, mobile phone number, home address, frequently purchased items, spending power and other information need to be completely handed over to a third party. Third-party organizations can draw your portrait according to your information, and will continue to improve it according to your consumption habits. Finally, the third party may know you better than yourself.
In fact, you just want to buy something, take a fancy to the goods, give the seller money, take the goods, and it's over. Where did it come from?
There are many problems in the centralization of shopping scenes, and information security is only one of them. Different scenes in life will have problems more or less because of centralization.
In order to avoid the problems brought by centralization, people put forward decentralization, but decentralization is not necessarily perfect.
For example, in decentralized transactions, when I paid the seller, he not only refused to deliver the goods to me, but also said that he sent them to me. I can't seem to defend my rights without a third party.
This problem can be clearly arranged by the seller through blockchain technology.
