Therefore, from the perspective of employment direction, blockchain technology talents can choose to work in different types of units such as financial institutions, technology companies, innovative enterprises, government agencies, etc., and engage in blockchain technology Development, application research, technical support, project management and other related work. At the same time, you can also expand your career development path through entrepreneurship and other methods.

C. What applications can blockchain technology have in the field of higher education and natural science research?

What applications can blockchain technology have in the field of higher education and natural science research?

Blockchain applications have a large number of application software, and the same is true for the education and training industry. Over the past few years, blockchain companies and enthusiasts have been researching and improving solutions for the higher vocational education industry. Here are some of the ways that blockchain technology can bring global innovation to the education sector around the world. One of the biggest applications of record storage blockchain technology in the education industry is the intelligentization of educational certificates, including bachelor's degrees, qualification certificates, academic qualifications, etc. This type of record storage can significantly increase the security of credentials, ensuring that no intermediaries are needed to verify these credentials. In addition, blockchain applications can be used for verification of training institutions.

A new operating model is not only concerned with improving the efficiency of record storage, reliability and test cases. There are also some blockchain applicationsDevelopment potential available as education board. One of the pioneering uses of blockchain technology is to build a new business model. Following this strategy, Woolf University aims to become the first boundaryless university powered by blockchain technology. The university was founded by a group of experts and scholars from the University of Cambridge and Cambridge University. The non-profit organization will be based on blockchain and smart contacts. This will become the prerequisite for the relationship between teachers and students.

D. What is Blockchain

In the simplest terms, blockchain is a distributed ledger.

To understand what this means, we first have to look at its opposite: a centralized ledger. Because blockchain technology started with finance, we will also introduce it below using banks as an example.

The following is our process for using bank debit card transactions:

You can swipe your card to purchase goods in stores.

The merchant sends a statement to your bank for the agreed upon amount.

Your bank will verify that you may have authorized the purchase.

The bank sends the money to the merchant.

Finally, the bank records this information in its ledger.

There’s a lot of technology involved here, but that’s basically it. The last step is important - the bank records all transactions made by the customer. This ledger goes all the way back to the first transaction the bank made.

This ledger is kept, maintained and regulated by the bank. You can read it in your online bank account, but you can't change it. The bank has complete control. If it decides to make a change, there's nothing you can do about it.

Crucially, if hackers were able to access a bank’s ledger, that could cause a lot of problems. They can change the account balance to make it look like certain transactions never occurred, etc.

This is why distributed ledgers are so cool.

Blockchain Network Visualization

If a bank operates on a distributed ledger, each member of the bank will have a copy of the ledger, and whenever any member of the bank When they make a purchase, they tell every other member of the bank.

Each member will validate the transaction and add it to the ledger (the added records are called "blocks"). This has some important benefits, as there is no centralized authority that can manipulate records. Hackers accessing one ledger won't be a big problem because other ledgers can easily verify it.

On the other hand, it requires a lot of work. In short, the second system is blockchain (at least in financial scenarios).

As mentioned above, blockchain is a decentralized list of transactions. likeIf I send Xiao Ming 2 Bitcoins, I send a message to everyone in the network saying "I am sending Xiao Ming 2 Bitcoins" and they all record the transaction.

The future of blockchain, how will it change our lives?

One thing that is important about blockchain is that it is a public resource and no one really owns it because everyone owns it.

Blockchain is not just science fiction. We don’t need to understand the mechanism behind this technology, but you do need to understand that it may completely change our lives in the next 20 years.

This may sound bold, but remember, 20 years ago we were browsing the Internet on Netscape, using state-of-the-art Motorola flip phones, and buying our first DVD players. At that time, if we imagined that a computer could be held in our hands and that we could buy cars, make payments, and watch movies, it would have been considered a fantasy.

Although the impact of blockchain may not be as obvious as the Internet, nor as tangible as mobile phones, blockchain will effectively solve many worries in daily life. Such as intermediaries cheating people, transaction delays, etc. In our current lives, middlemen are everywhere and we take them for granted as a part of life. If one day these intermediaries cease to exist, you will find that the world will become a different place.

Imagine that by 2040, blockchain may become a mature and widely used technology. When one day you can't live without the blockchain just like you can't live without the Internet now, you will be surprised to find that this decentralized accounting technology has simplified the complexity and become a part of your lifestyle

E. Is blockchain technology easy to learn? Can I learn it if I don’t have a high degree of education?

Blockchain technology is a very complex technology. Of course not too studious. Because if it is very good, it will not be so valuable if it is empty. But people with low academic qualifications can also learn, because learning like this also relies on talent.
Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
Characteristics of blockchain technology.
Decentralization. Blockchain technology does not rely on additional third-party management agencies or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes self-verification, transmission and management of information through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain.
Openness. The foundation of blockchain technology is open source. In addition to the private information of the transaction parties being encrypted, the data of the blockchain is open to everyone and anyone can pass it.The public interface is used to query blockchain data and develop related applications, so the entire system information is highly transparent.
Independence. Based on consensus specifications and protocols (similar to various mathematical algorithms such as the hash algorithm used by Bitcoin), the entire blockchain system does not rely on other third parties. All nodes can automatically and securely verify and exchange data within the system without the need for any human intervention.
Security. As long as you cannot control 51% of all data nodes, you cannot manipulate and modify network data at will. This makes the blockchain itself relatively safe and avoids subjective and artificial data changes.
Anonymity. Unless required by legal regulations, technically speaking, the identity information of each block node does not need to be disclosed or verified, and information transfer can be done anonymously
