区块链生活改变的原因,区块链生活改变了什么

A. What is blockchain technology? What impact may blockchain technology have on our lives?

Blockchain technology has not yet had a major impact on our lives. , but the future impact is estimated to be great

B. What changes can blockchain plus the service industry bring to life?

Although Bitcoin, as a representative of blockchain, has performed well this year There has been a significant reduction in market value, but this does not mean that the blockchain has lost its future. Perhaps in the long run, this is just the beginning.

I once translated an article explaining blockchain. I think it is easy to understand and I quoted part of the translation as a reference.
If someone came to you in 1992 and said, "Hey, this thing is called the Internet. Let me explain how you can create billions and billions of dollars of value in a whole new business model," how would you react? "Well, maybe you think you have the foresight to see the future of the Internet, but most people? The blockchain (truly decentralized) industry is in the same nascent stage, and the opportunities are huge.
Appeared in the article An architectural diagram about the blockchain. Because it is in English, I made a Chinese translation and conversion.

Many people say that the blockchain is “just a database”, which is true. . It is a distributed database (rather than centralized) where each entry in the ledger is timestamped and cryptographically secure, and linked to the previous and next set of entries in a "block" of transactions.
This connection forms a series of transactions. Therefore, the "blockchain" is not like the centralized institution itself claiming that "here is the state of the ledger", but the participants in the blockchain network maintain a consensus. Rejected anything that wasn't a good fit.
Having a distributed database is great in and of itself, but you don't always need one, and there's no real opportunity to create value (and monetize) it.
Blockchain is not just the foundation of digital currency. In fact, it is another system that will be different from the Internet in the future. It has its own philosophy, its own concepts, its own structure, and its own economic performance. If it is different from the Internet, The combination of service industries may show new economic manifestations. Taking Uber taxi (Uber Taxi, there is a similar Didi Taxi in China) as an example, Uber's economic model is like this:
In the Uber model, You join the network, and as more users/drivers join, the utility of the network increases. As the utility of the network increases, the value of Uber increases because they are actually the protocol (the rule setter), connecting buyers and sellers. In In this case, Uber represents a value appreciation to the owner of the "protocol".
If we define a blockchain taxi model and call it La'Zooz, its economic model is like this:
> La'Zooz created a token(They own the system token, it's called zooz) and provide it to network members.
Marketing issues aside, here’s what happens:
In order to pay for a ride, riders need Zoozs. Drivers receive Zoozs in return for driving. Since currencies have a finite amount (or predictable inflation by definition) based on protocol rules — (even though they are digital, so they can be cost-effectively divided into multiple decimals), each zooz The value of increases as the demand for them increases.
Let’s think about it simply:
There are 100 Zoozs coins in the blockchain.
Each Zooz is worth $1.
There are 100 network participants. 50 drivers and 50 passengers.
Each ride costs 1 Zoozs.
Assuming La’Zooz is cheaper than Uber, more people want Zoozs. Therefore, they exchange USD or Bitcoin for Zoozs, which increases the price of Zoozs to $2. So now everyone has a value of $2 instead of $1.
Purchasing power has been doubled, so you can use 1 Zoozs for 2 rides. So you sell half the Zoozs to someone who needs them, and let the other person ride them too.
Drivers who have been awarded 1 Zoozs now see the value of the driving services they have provided in the past going from $1 to $2 and are more inclined to accept Zoozs because they want more people to join the network. In effect, by acquiring these tokens, you gain value today and gain value in the future.
In this model, it is not Uber that gains profits, but the owners of the network (token holders)!
This is what happens in all types of networks: identity networks, credit networks, social networks
Consumers are not just consumers, they are also part of the producers, and the blockchain brings the right to use value and unified service income rights. Every consumer becomes a producer in the business system. Programming benefits into an automatic distribution mechanism becomes an autonomous economic system.

We still need to maintain an attitude of awe towards the development of science and technology, and we need to keep a cool head towards the craze of capital. In the future, I believe there will be more technologies to change our lives.

C. What effect does blockchain have on real life?

Blockchain is essentially a disintermediated database that uses a blockchain data structure to verify and Store data, use distributed node consensus algorithm to generate and update data, use cryptography to ensure the security of data transmission and access, and use automated script codeA new distributed infrastructure and computing method composed of smart contracts to program and operate data. In layman's terms, blockchain is a distributed accounting technology, which has the characteristics of decentralization, non-tampering, and node consensus mechanism. Although it sounds a bit obscure, it can actually bring tangible benefits to our daily lives:
First, blockchain technology can be used to establish a traceability mechanism for food and vegetables, completely eliminating source pollution of food and vegetables, and providing the common people with Safe and hygienic green food and vegetables allow everyone to buy and eat with confidence;
Second, blockchain technology can be used to store various ownership certificates and notes and transcripts, completely eliminating fake certificates, fake files, fake academic records, fake medical records, fake transcripts, etc. Fraudulent incidents occur;
Third, blockchain technology can be used to conduct community election voting, completely eliminating fake votes and truly achieving openness, fairness and impartiality. Build a democratic community and achieve democratic governance.
In addition, blockchain technology can also be used in many aspects of daily life such as charity fundraising and commodity anti-counterfeiting.

(4) Blockchain Life Changes Extended Reading:

Blockchain is far more than just a technology, behind it involves " The spirit of multi-party collaboration. In modern society, many things must rely on everyone's cooperation to achieve the effect of 1+1>2, but in cooperation, we need to try our best to avoid problems such as "information asymmetry."

Therefore, alliance members jointly keep accounts, share data, and make everything public to eliminate "information asymmetry" to protect everyone's interests and allow the business environment to develop healthily. If you do things honestly, you will get the benefits you deserve. If you cheat, it will be known to everyone and criticized by thousands of people. Technology is the foundation that helps realize this model. This is the more important "blockchain thinking".

E. What changes can blockchain bring to data sharing

What changes can blockchain bring to data sharing
Currently, text sharing on social networking sites Taking photos and sharing each other's joys, sorrows and joys have 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 and provide more information than paper archives.Larger capacity allows 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 organizations also need to complete data modification and other behaviors under certain laws and agreements, because they are the party that controls the resources, it is difficult for individual users to enjoy 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 there is an organizationIf an operation outside the rules is performed, 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 method, the participants themselves are the managers, which is the core expression of blockchain decentralization: no institution is superior to others and has complete control authority 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.

F. Under the Internet of Everything, what does the blockchain bring to us

The transmission of Internet information is used in business reception, culture and education, diagnosis and treatment, finance, industry and agriculture, etc. The field has been widely used and developed in depth, driving the integration of many stages such as manufacturing, sales, operations, and management methods. At the same time, it has promoted the progress of online games, IT, news media, tourism and other related industries. The overall information management solution combined with the network has also demonstrated positive significance in the fields of public security agencies, securities, transportation and travel.

Internet technology has become an indispensable part of everyone's daily life. Internet technology is widely used in real life. On the Internet, everyone can chat, play games, view items, etc. More importantly, on the InternetYou can also advertise and buy things online. Internet technology brings great convenience to our daily lives. On the Internet, people can search for their academic and career needs in the data knowledge base system to assist them in their work and study. Computers can be used for multimedia learning, playing games, watching TV series, reading information, and searching for information. But if you overdo it, there will be disadvantages, just like I am still at home online and not sleeping at night.

G. What is the mystery of blockchain technology and what impact will it have on people’s production and life?

Bitcoin was invented in late 2008 and early 2009 Virtual currency, he published an article "Bitcoin: A Peer-to-Peer Electronic Cash System". Blockchain technology is a technology he uses. In other words, Bitcoin is the world's first "decentralized" digital currency. In order to invent it, Satoshi Nakamoto created a new technology and named it "blockchain". In 2019, the country placed great emphasis on accelerating the development of blockchain technology and industry in collective learning. An important characteristic of blockchain is that it is decentralized, cannot be tampered with, and cannot be forged.

Blockchain technology will definitely have great potential in the future. Now it is a new technology, and people may not be familiar with it, so their acceptance is not high. However, with the support of national policies, the advantages of blockchain technology have become more prominent, and the fields of application will be more extensive in the future.

H. What earth-shaking changes will blockchain bring and how will it change life?

In addition to being used in the financial industry, blockchain is also used in other fields. In fields such as law, retail, Internet of Things, and medical care, blockchain can solve trust problems, no longer rely on third parties to establish credit information sharing, and improve the operating efficiency and overall level of the entire industry. Extremely high productivity will connect all people and machines in this society into a global network, and mankind will accelerate towards an era where goods and services are almost free. Perhaps by the second half of the 21st century, capitalism will decline and areas The decentralized collaborative sharing model of the blockchain will replace it and become the new model that dominates economic life.

Blockchain is the best technical means for this new collaborative sharing model. The infrastructure of blockchain allocates global resources in a decentralized manner, making blockchain an ideal technical framework for promoting social and economic development. The operational logic of blockchain lies in its ability to optimize peer-to-peer resources, global collaboration, and the sensitivity that fosters and encourages the creation of social capital in society. Establishing various platforms for blockchain can encourage a collaborative culture to the greatest extent, which complements the original shared model and will make it the decisive economic model of the 21st century.

I. How will the blockchain affect the food, clothing, housing and transportation of ordinary people in the future

How will the blockchain affect the food, clothing, housing and transportation of ordinary people in the future
To answer this question we need to open up our minds a bit
Let’s talk briefly firstNext Characteristics of blockchain technology:
Data security is high, and data using blockchain technology is almost impossible to be tampered with.
Data cannot be changed after being recorded.
Data can be highly transparent and can be seen by everyone.
Distributed nodes, data is not recorded in a single central server, but distributed among various distributed nodes.

What changes will these technological features bring to our future lives?
Let us imagine the life of an ordinary person, Xiaoyu, after 30 years when blockchain technology is highly popularized.
First of all, let’s introduce our protagonist Xiaoyu: Xiaoyu is 30 years old and is a freelance writer and photographer. I live in Xingfuli, Dongdaqiao Road, Chaoyang District, Beijing... What, Xiaoyu is a rich man?
No, Xiaoyu is just an ordinary person.
Why can ordinary people afford a house in Xingfuli?
In fact, in the blockchain era 30 years later, both cities and companies have been decentralized. Most people do not have to work through a company to serve others, they only need to provide services on the blockchain. Therefore, there is no need for most people to work in companies concentrated in urban centers. People began to move out of the city and live in satellite towns around the city. Or simply move to a rural town with equally well-equipped facilities. Housing prices in the city center have naturally dropped.
In fact, a house in the center of Beijing will not be more expensive than a villa in a surrounding satellite city 30 years later. Xiaoyu bought this house just to facilitate his photography and collecting in Beijing.

Xiaoyu got up early and took out the milk and bacon bread bought last night from the refrigerator to make a breakfast. In fact, food safety issues have been forgotten after 30 years. Because every can of milk, from the health status of the cow, to factory packaging, to transportation, is recorded in the blockchain. The entire industry chain has been made transparent and updated in real time, and every transparent blockchain will be supervised by artificial intelligence. Once there is a problem in a certain link, artificial intelligence will immediately issue an alarm.
Within three years after the operation of this blockchain recording + artificial intelligence supervision system, the food safety problems that have troubled people for many years will be solved.
After breakfast, Xiaoyu started his day's work. He works about two hours a day, three to four days a week. The main content of the work is to upload the photos I took during this period to the blockchain platform, write a travel experience to introduce my photos, and spend some time communicating with my fans on the platform's social media.
Every uploaded photo will be encrypted by the blockchain, and users can read Xiaoyu’s articles and see photo thumbnails for free. But if you want to download high-definition pictures, you must pay to Xiao Li's account to download.
In fact, when the entire network is blockchain-based, piracy will become a veryDifficult things. Because if a user wants to make money from Xiaoyu’s photos, they must obtain Xiaoyu’s authorization. Otherwise, once the user uploads the image to the network, it will be recorded by the blockchain. When accountability is held in the future, every penny this pirate makes through piracy will be traced and held accountable.
30 years later, the popularity of blockchain has completely solved the problem of piracy. Therefore, individual photographers like Xiaoyu can make a good income by relying on the copyright of their own photos.
After work, we had lunch. Xiaoyu remembered that he had made an appointment with his dentist in the afternoon. Get ready to go out and take a taxi. Thirty years later, hailing a taxi will no longer be through a certain company’s taxi hailing software. Instead, just pay on the taxi-hailing platform, and the smart contract in the blockchain will automatically match the car rental driver after receiving the payment. So Xiaoyu only needs to say to his mobile phone before going out: I want to go to the dentist. And just transfer money to the taxi driver's electronic wallet. When we got downstairs, the taxi was already waiting there.
When we arrived at the dental clinic at the appointed time, Xiaoyu didn’t need to show any medical records. Just use your private key to unlock your case record blockchain and give it to the dentist. The dentist will make judgment and treatment based on the last case record. Then make a new record in the blockchain.

After coming out of the dentist's office, Xiaoyu sat down at a nearby automatic cafe and ordered a cup of coffee using his e-wallet to pay. And go to the blockchain community to see the progress of his various photography projects - Xiaoyu has planned a lot of photography plans for himself, including a photography plan to Antarctica and a photography plan to the Amazon rainforest. But these plans require more funding and a working group that includes planners, photographers, local route planning experts, etc. It is beyond Xiaoyu's ability alone.
So Xiaoyu packaged these plans and ideas and put them in the blockchain community: raising funds for the project and looking for like-minded partners and colleagues. And attached his own blockchain information.
Every Internet user in the world can see these projects, as well as Xiaoyu’s personal credit information. If they feel that this project or this person is reliable, they can transfer any amount of money from their e-wallet to Xiaoyu's account to donate or invest in the project. Interested and like-minded people can also express their willingness to go together. Xiaoyu can find suitable participants based on the credit information of the willing people and the personal resume blockchain. Form a temporary working group to complete the project.
Obviously, there is a future for improving the blockchain credit system. We no longer need to go through banks for financing and borrowing. The way people organize production has also broken away from the scope of the company.
These are some of the details that I can think of that blockchain technology can change our lives in the future. The writing is not very comprehensive. I hope friends who read it will give me more opinions and open up your own imagination.
Blockchain technology is currently a very promising revolutionary technology. Although currentlyIt hasn't quite hit the ground yet. But I believe it will slowly develop and mature over time. And bring disruptive changes to our future.

J. What changes will blockchain technology bring to our lives

Don’t promote blockchain technology too much. To put it bluntly, it is a distributed accounting system. It's not a new technology. If there were no Bitcoin, people might never pay attention
