What changes can blockchain bring to data enjoyment?

At present, sharing words and photos on social networking sites and sharing each other's joys and sorrows has become an important part of public life.

With the progress of the times, * * * enjoyment has gradually entered the real society, and a series of * * * enjoyment economic models have emerged, such as * * enjoying bicycles, * * enjoying umbrellas, * * enjoying charging treasures and * * enjoying cars, which have brought great convenience to human life.

As a distributed ledger, blockchain technology seems to be inherently inseparable from * * *, and people in the industry constantly claim that this technology can bring revolutionary progress to * * *.

So, what is the difference between blockchain enjoyment and Internet-based enjoyment? This paper takes data sharing as an example to answer this question.

Blockchain * * * enjoys more than just data.

Data sharing is an innate demand of people, such as talking about life ideals and writing in cafes, which are important ways for ordinary people to exchange information with others.

The emergence of the Internet has broken the geographical and time limitations of data, allowing different people to communicate in different places on the earth. The emergence of e-mail, online instant messaging and other technologies has greatly improved the efficiency of information transmission.

In addition, the Internet can collect massive data, provide a larger capacity than paper documents, and allow users to obtain rich information in a short time.

So, under the blockchain technology, what is the difference between all this?

In fact, blockchain technology is not concerned about * * * enjoying data, but * * * enjoying data control. Permission here mainly refers to the power to modify and increase data, which mainly includes two meanings:

One is who can modify the data.

The second is how to modify it.

In the Internet mode, data reading, writing, editing and deleting are generally accompanied by authentication operations, and only specific people can modify data. In the blockchain mode, especially in the public chain system, anyone can participate in reading and writing data and build an untrusted system in the form of distributed account books. Organizations or individuals involved in reading and writing cannot trust each other, but they can know the final state of the data stored in the system.

Simply put, the essential difference between blockchain * * * and Internet * * * is that blockchain * * * enjoys not only data, but control over data. So, how does blockchain handle data control?

Blockchain controls data through rules.

Before the emergence of blockchain technology, Internet data was usually controlled by a single entity. Since website operators have complete control over the central server, these organizations can edit and process data at will. Although under certain laws and agreements, organizations also need to complete data modification and other behaviors, it is difficult for individual users to enjoy complete control because they are the ones who control resources.

For a simple example, a user uploaded a photo to the website platform, hoping his friends could see it. Excluding some illegal elements, who is the ultimate owner of this photo?

Obviously, from the user's point of view, this photo belongs to himself, but in fact, these social networking sites are the real controllers. They can modify it at will, but users have no choice.

That is to say, under the existing Internet system, as long as you master the operation right of the website platform, you can completely control the data on the platform.

Under the blockchain system, data is not controlled by any authority, and its authority is controlled by rules. The main goal of these rules is to specify what kind of information is valid, and also how participants should feedback this information.

These rules are usually predetermined, and participants who join the blockchain network must abide by these rules. Of course, technically, participants can ignore some rules and construct some invalid data according to their own interests. However, due to the existence of blockchain knowledge mechanism, other participants can exclude these invalid data from the network according to predefined rules.

For example, in the blockchain blacklist platform system launched by Suning Financial, there are many such rules-you can't query any data without points, and only this institution has the right to modify its data, and so on. Once the institution has done operations outside the rules, these operations will be regarded as invalid transactions and prohibited from happening.

Generally speaking, the blockchain regulates the writing behavior of data according to the technical rules system, while the Internet controls data through power and resources, which is the fundamental difference between blockchain * * * enjoyment and Internet-style * * * enjoyment.

Blockchain rules are maintained by participants * * *

Although there are some rules in the internet environment, it is difficult to avoid black-box operation because the rules are completely maintained by the authorities. In the blockchain system, the rules are maintained by all participants, and each participant will independently verify the data according to the rules.

In this process, we can't assume that all participants can completely abide by the rules. Therefore, each participant will independently verify the received data and judge whether it violates the rules. If the data is verified to be valid, the participants will accept the data and forward it to others, otherwise, they will directly reject the data.

In the blockchain network, new data can only be regarded as valid data after the consent of relevant participants, and added to the final blockchain enjoyment account book.

According to the construction method of blockchain, the data confirmation method is quite different. For example, in the public chain, most participants need to agree on the validity of data, while in the alliance chain or private chain, only a few participants need to agree.

In this way, the participants themselves are managers, which is the core embodiment of blockchain decentralization: no organization is superior and has complete data control.

Blockchain is in the form of permission sharing, so that each participant can be a data provider, verifier and user at the same time, and * * * maintain the security and effectiveness of blockchain data.

Since the blockchain has become hot, everything can be said that blockchain seems to be an advertising word in the industry, especially some data sharing applications will be considered as excellent cases of blockchain.

In fact, the emergence of the Internet has solved the problem of * * * sharing of data to a certain extent, and the blockchain has realized the * * * sharing of permissions, which is the most revolutionary change that blockchain has brought to the industry.
