『一』What changes can blockchain bring to data sharing

What changes can blockchain bring to data sharing
Currently, on social networking sites Sharing words and photos on the Internet, as well as sharing each other's joys, sorrows, sorrows and joys, has become an important part of public life.
With the progress of the times, sharing is gradually entering the real society. A series of shared economic models such as shared bicycles, shared umbrellas, shared power banks, and shared cars have emerged, bringing great convenience to human life. .
As a distributed shared ledger, blockchain technology seems to be inherently inseparable from sharing, and industry insiders continue to claim that this technology can bring revolutionary progress to sharing.
So, what is the difference between blockchain-based sharing and Internet-based sharing? This article takes data sharing as an example to answer this question.

Blockchain shares more than just data
Data sharing is an innate need of human beings. For example, talking about life ideals in a cafe, writing text, etc., these are all An important way for ordinary people to communicate information with others.
The emergence of the Internet has broken the geographical and time limitations of data sharing. It allows different people to communicate instantly in different locations on the earth. The emergence of email, online instant messaging and other technologies has greatly improved the efficiency of information transmission. efficiency.
In addition, the Internet can collect massive amounts of data, providing a larger capacity than paper archives, allowing users to obtain rich information in a short period of time.
So, how is all this different under blockchain technology?
In fact, blockchain technology is not concerned with the sharing of data, but the sharing of data control permissions. The permissions here mainly refer to the power to modify and increase data. It mainly contains two meanings:< br />One is who can modify the data
The other is how to modify it.
In the Internet model, data reading, writing, editing and deletion are generally accompanied by identity authentication operations. Only specific people can modify the data. In the blockchain model, especially the public chain system Under this system, anyone can participate in reading and writing data, and a trustless system is built in the form of a distributed ledger. The various organizations or individuals participating in reading and writing can not trust each other, but can store the final status of the data in the system. Reach a consensus.
To put it simply, the essential difference between blockchain-based sharing and Internet-based sharing is that blockchain shares not just data, but the control of data. So, how exactly 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 the website operator has complete control over the central server, these organizations can edit and process the data at will. Although the organization also needs to complete data modification and other actions under certain laws and agreements, because it is the party that controls the resources,It is difficult for individual users to have complete control.
To give a simple example, a user uploads a photo to the website platform and hopes that friends can see the photo. Excluding some illegal elements, who has the final control over this photo?
Obviously, from the user's point of view, this photo belongs to them, but in fact, these social networking sites are the real controllers. They can modify it at will, but users have nothing to do.
In other words, under the existing Internet system, as long as you have the right to operate the website platform, you can completely control the data on the platform.
Under the blockchain system, data is not controlled by any authoritative party, and its authority is controlled by rules. The main goal of these rules is to stipulate what kind of information is valid, and also stipulates How participants should provide feedback on it.
These rules are usually pre-defined and participants joining the blockchain network must abide by the rules. Of course, technically speaking, participants can ignore certain rules and construct invalid data based on their own interests. However, due to the existence of the blockchain consensus mechanism, other participants can exclude these invalid data from the network based on predefined rules.
For example, in the blockchain blacklist sharing platform system launched by Suning Financial, there are many such rules-no data can be queried without points, only the organization has the authority to modify the data of this organization, etc. Once an institution performs an operation outside the rules, these operations will be regarded as invalid transactions and are prohibited from occurring.
In general, blockchain regulates data writing behavior based on a technical rule system, while the Internet controls data through power and resources. This is the foundation of blockchain-style sharing and Internet-style sharing. sexual distinction.
Blockchain rules are jointly maintained by participants
Although there are some rules in the Internet environment, because the rules are completely maintained by the power parties, it is difficult to avoid black-box operations and other behaviors. In the blockchain system, the rules are jointly maintained by all participants, and each participant will independently verify the data according to the rules.
In this process, we cannot assume that all participants can fully comply with the rules. Therefore, each participant will independently verify the data it receives and determine whether it violates the rules. If the verification data is valid, then the participant will accept the data and forward it to others, otherwise, it will be rejected directly.
Within the blockchain network, new data can be considered valid data and added to the final blockchain shared ledger only when relevant participants agree.
Depending on how the blockchain is constructed, there are big differences in how data is confirmed. For example, in a public chain, most participants need to agree on the validity of the data, while in a consortium chain or private chain, Only a few participants need to agree.
In this way, the participants themselves are managers, which is the districtThe most core expression of blockchain decentralization: no institution is superior to others and has complete control over the data.
Blockchain is a form of permission sharing, allowing each participant to serve as a data provider, verifier and user at the same time, jointly maintaining the security and validity of blockchain data.
Since the popularity of blockchain, blockchain for everything seems to have become the advertising slogan of the industry, especially some data sharing applications are considered to be excellent examples of blockchain.
In fact, the emergence of the Internet has solved the problem of data sharing to a certain extent. Blockchain realizes the sharing of permissions. This is the most revolutionary change that blockchain has brought to the industry.

『二』What are the most profitable investments?

The most profitable investment projects are: specialty snack bars, greenhouse cultivation, farmhouses, vehicle repair shops, and comprehensive canteens.

1. Farmhouse

It is possible to make money by opening a flavor shop and selling farmhouse dishes in the urban-rural fringe area. First, country-style stores can attract urban consumers. Nowadays, many city people are tired of the dishes often found in restaurants, and would like to taste farm-style dishes.

2. Greenhouse cultivation

In the new century, the awareness of green, pollution-free and organic food is deeply rooted in the people. Producing green and organic vegetables to protect the health of consumers has become the consensus of the majority of vegetable farmers.

5. Comprehensive canteen

In every village, there are several canteens, and this is the one with the largest flow of people every day. Since rents are cheap in rural areas, daily necessities, school supplies, tobacco, alcohol and food, and sometimes groceries are all available, making it convenient for villagers to purchase. This small business still has great potential for development.

Investment Notes:

1. Determine whether the project requires financial investment or strategic investment

Generally speaking, financial investment mainly provides funds for the invested enterprise. Money is the main thing; in strategic investment, in addition to investing money in the invested company, it will also establish business contacts and resource assistance with the company.

2. Communicate with the investment company about the project and other investment companies

In the process of finding an investment company, entrepreneurs should not be limited to one investment company or one investor. But for those who are interested in investing, we will take multiple measures to capture the situation.

『三』Is the blockchain economy the real "sharing economy"?

Recently, some people have been questioning the sharing economy.

First of all, some people questioned Didi, saying that after Didi acquired Kuaidi, Uber China and other online ride-hailing companies, because one company has become the dominant one, There is no need to grab users, so we simply cancel the subsidy. This leads to a reduction in the income of a large number of drivers. Slowly, many drivers quit the Didi platform.

Or think about how to digitize all these idle resources and how to connect them to the blockchain system!

『四』 The following itemsAmong the projects, which ones belong to the "Internet +" new technology projects

1. Zhejiang University Yunwang Zaoxiang "Blockchain" project
2. Huazhong University of Science and Technology's "Zhuge IO" project
3. Peking University’s “OFO” shared bicycle project
4. Insta360 panoramic camera
Junyuyanque belongs to the “Zaobo Internet+” new technology project

『五』 How to integrate blockchain with the sharing economy

In general, grasping the essence of blockchain should be weak control, decentralization, autonomous mechanisms, network architecture and coupled connections. The essence of blockchain should be a new social structure in the information society era that is completely different from industrial society. The five core points about blockchain have something in common with the sharing economy. The essence of the sharing economy is to abandon the old development mechanism and no longer emphasize concentration. Instead, use decentralized social resources in a peer-to-peer manner to allow participants to participate and contribute in different ways. to gain.
Blockchain and sharing economy, two mutually relevant Internet hotspots, happen to have ample "space for cooperation." From theory to practice, there have been many bold explorations in the industry, and there have even been some phenomena that challenge traditional business models. In this way, the sharing economy tied to the blockchain will be a brand new business model and a new subversion of interpersonal relationships. I plan to invest in the blockchain industry. After all, in the Internet era, I searched for Guangzhou Xuanling Technology Co., Ltd. and looked at the web page. They are a company that develops software blockchain smart contracts. There are many cases developed and the team is strong.

『Lu』 New opportunities for blockchain development, the future under the new sharing model

1. After equipped with blockchain, the "new sharing" of computing power candy Power Candy has taken shape< br />
The sharing economy is booming in the Internet environment, but in the current sharing model, "physical sharing" is still the mainstream model, such as shared bicycles, shared charging, shared luggage, shared hotels, etc.

It is true that the contradiction between idleness and lack of physical resources in different projects is the most obvious. For example, people often face traveling without a car or do not want to drive. Therefore, the physical sharing model emerged as the times require. In addition, technological simplicity also allows the most direct application of sharing physical objects to be implemented first.

In fact, blockchain is consistent with the sharing economy in terms of technical applications and business models. The POC computing power candy + sharing economy model launched in 2018 has catalyzed the "new sharing" There is a realized application foundation and long-term prospect planning, which may help the new sharing economy get out of the fog and keep the blockchain away from the hustle and bustle.

The key to the problem becomes how to establish mutual trust with the participation of multiple parties, and decentralization ensures that there is no interest control. This coincides with the concept of POC computing power candy. The launch of POC super nodes is undoubtedly the inevitable result of computing power candy realizing "new sharing" with the help of blockchain technology.

Referring to the concept of the white paper, a series of application scenario settings of POC are also in line with the two-way catalytic relationship between blockchain and "new sharing". This may be the reason for the announcement amidst the clamor of blockchain public opinion. The reason why the POC at the meeting was still confident.

2. "New Sharing" + Computing Candy POC Jumps to the Technical Level

First of all, it is the catalytic effect of computing power candy technology on "New Sharing", which is more reflected in On a technical level.

(1) This new sharing feature is actually decentralization, the concept of "weakening platform ownership and strengthening shared management rights", which again coincides with POC computing power candy, using new It is inevitable for technology to achieve new shared decentralization. The principle is that the computing power candy platform does not need to participate in the transactions between users, and these "rights" are owned by the super nodes, and POC has countless nodes, thus achieving decentralization and new sharing by super nodes. Model principles.

(2) "To own but not to possess", both have the same vision of decentralization. There are multiple stakeholders in the new sharing of POC computing power candy, which essentially follows the "own but not possess" characteristic of the sharing economy: all participants can enjoy the resources in the system equally and efficiently, but no one can possess the system. Seek extra personal gain of your own. Each user has the right to become a super node, perform their obligations under the supervision of the entire network, and independently obtain super node benefits.

3. Power Candy + "New Sharing" to realize the Internet of Value

(1) The goal of Power Candy is ultimately to return to how to deliver value . Although when it comes to blockchain, public opinion talks about keywords such as decentralization and trust mechanisms. From the practice of POC, we can also see that these characteristics have obvious technical and commercial value, but in terms of computing power candy For Power Candy itself, decentralization, trust, etc. are just the means to achieve its ultimate goal of value Internet. This meansThis means that the participants in the POC project must transfer value to each other through it rather than traditional information. This has also become one of the criteria for identifying those "pseudo-blockchains".

(2) The combination of POC and blockchain is the appropriate practical field for the value Internet

The value of the value Internet in the computing power candy Power Candy means not only monetary value, Rather, it generally refers to resources that can produce utility. In POC planning, these values ​​realize direct flow, rather than needing to be translated from information into value (for example, WeChat's payment is essentially sending instruction information and then the transfer is executed by Tencent's backend).

In addition to reliable digital currency projects, POC is undoubtedly the most suitable blockchain application field for value flow. According to IHS forecasts, the global installed base of IoT devices will reach 20.7 billion in 2020 and 75.4 billion in 2025. In such a huge network, there are a large number of value (computing power, storage, bandwidth, scenario analysis, identity authentication, payment authentication, etc.) flow requirements.

4. As the performance increases and the loss decreases, there are more possibilities for new sharing

Whether it is from new sharing to POC computing power candy, or from POC computing power candy to New sharing, both are mutually beneficial processes. In a situation where digital currencies have copied mining models as incentive mechanisms and are widely questioned, the combination of the sharing economy and POC computing power candy shows that blockchain can reversely reduce social costs. Resource consumption, performance improvement paradigm.

In any case, in today's world of constant quarrels about blockchain, under the new sharing concept, the POC computing power candies tied to the sharing economy provide a solution that is not objectionable either at the logical level or at the intuitive level of the public. Blockchain practical cases, new sharing will have more application possibilities.
