To answer this question, we need a good brain hole.

Let me briefly talk about the characteristics of blockchain technology:

Data security is high, and it is almost impossible to tamper with data using blockchain technology.

Data cannot be changed after being recorded.

Data can be highly transparent and everyone can see it.

Distributed nodes, data is not recorded on a single central server, but distributed on each distributed node.

What changes will these technical features bring to our future life?

Let's imagine the life of an ordinary person after the blockchain technology is highly popularized 30 years later.

First of all, introduce our hero Xiao Yu: Xiao Yu, 30 years old, student, freelance writer and photographer. Who lives in Happiness Lane, Dongdaqiao Road, Chaoyang District, Beijing ... What, Xiaoyu is a local tyrant?

No, Xiaoyu is just an ordinary person.

Why can ordinary people afford a house in happiness?

In fact, in the blockchain era 30 years later, both cities and companies have been decentralized. Most people don't have to serve others through the company, but only need to provide services on the blockchain. So most people don't need to work in companies concentrated in urban centers. People began to move out of the city and live in satellite cities around the city. Or simply move to a rural town with the same facilities. House prices in the city center will naturally fall.

In fact, the house in the center of Beijing is not more expensive than the villa in the surrounding satellite city after 30 years. Xiaoyu bought this house only for the convenience of taking pictures in Beijing.

Xiaoyu got up early in the morning and took out the milk and bacon bread bought in the refrigerator last night to make a breakfast. In fact, 30 years later, food safety has been forgotten. Because every can of milk is recorded from the health status of dairy cows to the packaging and transportation of factories. The entire industrial chain has always been transparent and updated in real time, and every transparent blockchain will be supervised by artificial intelligence AI. 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 problem that has plagued people for many years has been solved.

After breakfast, Xiaoyu started a day's work. His working hours are about two hours a day, ranging from three to four days a week. The main content of my 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 social media of the platform.

Every uploaded photo will be encrypted by the blockchain, and users can read Xiaoyu's articles and view photo thumbnails for free. But if you want to download the high-definition map, you must pay Xiao Li's account to download it.

In fact, when the whole network is a blockchain, piracy is a very difficult thing. Because users want to make a profit with Xiaoyu's photos, they must pass Xiaoyu's authorization. Otherwise, once the user uploads the picture to the network, it will be recorded by the blockchain. When the responsibility is investigated in the future, every penny earned by the pirate through piracy can be found out and investigated for responsibility.

Thirty years later, the popularity of blockchain completely solved the problem of piracy. Therefore, an individual photographer like Xiaoyu can earn a good income by relying on the copyright of his own photos.

After work, I had lunch. Xiaoyu remembers that she had an appointment with the dentist this afternoon. After 30 years of going out to take a taxi, taking a taxi is no longer through a company's taxi software. But you can pay on the taxi platform. The smart contract of blockchain will automatically match the car rental driver after receiving the payment. So Xiaoyu just said to her cell phone before going out: I'm going to see a dentist. Put the money in the taxi driver's e-wallet. When I went downstairs, the taxi was already waiting there.

At the dentist's office at the appointed time, Xiaoyu doesn't have to show any cases. Just use your private key to unlock your own case record blockchain dentist. The dentist will judge and treat according to the last case record. Then set a new record in the blockchain.

Coming out of the dentist's office, Xiaoyu sat down in the nearby automatic cafe and ordered a cup of coffee with her electronic wallet. There is also going to the blockchain community to see the progress of various photography projects-Xiaoyu has planned many photography plans for herself, including going to the Antarctic photography plan and going to the Amazon rainforest. But these plans need more funds and a working team including planners, photographers and local route planning experts. This is beyond Xiaoyu's ability.

So Xiaoyu packaged these plans and ideas and put them in the blockchain community: raising funds for the project and finding like-minded partners and colleagues. And attached their own blockchain information.

Every netizen in the world can see these projects and Xiaoyu's personal credit report. If they think this project or this person is reliable, they can make any money from their e-wallet to Xiaoyu's account, donate money or participate in the project. Interested and like-minded people can also express their willingness to go together. Xiaoyu can find suitable participants according to the credit information of those who are willing and the blockchain of their resumes. Set up a temporary working group to finish the project.

Obviously, improving the blockchain credit system is promising. We don't even have to go through the bank for financing and borrowing. The way people organize production has also gone beyond the scope of the company.

This is some details that I can think of that blockchain technology can change our future life. It's not very comprehensive I hope my friends will give me more advice and open my own brain by the way. Imagine that.

Blockchain technology is a revolutionary technology that is very optimistic at present. Although it hasn't completely landed yet. But I believe that with the passage of time, it will gradually develop and mature. And bring subversive changes to our future.
