㈠ Peking University Jade Bird Design Training: The Element Architecture of Blockchain Technology

With the continuous development of the Internet, more and more people have learned about blockchain Some characteristics and usage of technology. Today we will introduce to Huisun what some elements of blockchain are in Guizhou.
Composition of Blockchain Blockchain consists of blocks and chains.
Each block contains three elements: data, hash value, and the hash value of the previous block.
The first element of the block is data.
The data stored in the block is related to the type of blockchain.
For example, blocks in the Bitcoin blockchain save relevant transaction information, including sellers, buyers, and the amount of Bitcoin traded.
The second element of the block is the hash value.
Each block contains a hash value, which is used to identify a block and all the content it contains.
Once a block is created, its hash value is calculated accordingly.
Changing something in the block will cause the hash value to change.
So in other words: hashes are helpful when you want to detect changes to content in a block.
If the fingerprint of a block changes, it is no longer the same block as before.
The third element of the block is the hash of the previous block.
This element allows links to be formed between blocks and makes the blockchain very secure.
For example, suppose we have a blockchain containing 3 blocks.
Each block contains its own hash value and the hash value of the previous block.
Block No. 3 points to Block No. 2, and Block No. 2 points to Block No. 1.
But block No. 1 is a bit special, it cannot point to the previous block because it is the first block.
We call block 1 the genesis block.
So, now let's assume you tampered with the second block.
This will cause the hash value of the second block to change, so the data stored in block No. 3 will be wrong and illegal.
Once the data stored in block 3 is illegal, the following blocks must also be illegal.
So if a person wants to tamper with any block in the blockchain, it must modify this block and all blocks after this block.
This will be a heavy task.
Blockchain's Proof of Work However, the method of using hash values ​​alone is not enough to prevent users from tampering with blocks.
Because today's computer computing speed is powerful enough and can calculate thousands of hash values ​​per second.
java course http://www.kmbdqn.cn/ suggests that you can completely tamper with a block and recalculate the hash values ​​of other blocks, thus making your block legal again.

㈡ Blockchain Case｜Being like a rat with Peking University on your back—difficult!

The story starts with the blockchain project.We know that many of the founders of blockchain capital have backgrounds in prestigious universities, especially Peking University, Qingdao University and top foreign universities. This is not an accident. As far as I know, entrepreneurs or partners are more diligent than you think. Of course, most of them have a good educational background and will naturally pay attention to trends.

However, a small number of capitalists like to use their educational background to sugar-coat their jobs in Gaofu.

Why? I believe you and I both know it clearly but have not said it or it is difficult to explain it.

Today, let’s take the Hero Entertainment Chain, which has been widely infamous in the chain currency circle for more than half a year due to air currency, as an example:

The Hero Chain public account has been suspended for more than a year.

"In May of this year, CCTV News directly named the Hero Chain project, accusing it of committing false fraud in the name of tokens. As the sales director of Hero Chain, Peking University talent Liu Hongyuan became the target of public criticism after the incident. .

After the incident, Liu Hongyuan ran away to Singapore, and Hero Chain CEO Gao Zhun also led his team to Cambodia." - The little monster next door.

What is the Hero Entertainment Chain? Who are the people on the platform?

"Hero Chain (HEC) was launched in January this year. It is a gambling game platform that supports digital cryptocurrency. The project CEO is Micro Motion."

Hero Chain White Paper:< br />
Who is Liu Hongyuan, and how did he get involved in the hero chain?

Liu Hongyuan, former president of Peking University Venture Capital Research Association. As an angel investor, Chen Manli had an educational background at Tsinghua University that could easily connect with college students. She took a fancy to Liu Hongyuan, who was anxious about starting a business.

“In addition to Liu Hongyuan, people who participated in proxy investment include Wang Dapao, Mr. Bai, Bit Wu, etc. These people have contributed to the sales of Hero Chain.”
< br />As can be seen from the white paper, Hero Chain tokens are stipulated not to be circulated within one year and will be locked. Funds raised are used for development.

The manipulator behind the Hero Chain Entertainment Chain is actually Hash Capital Chen Manli.

So, who is Chen Manli?

She works in ten companies including Dream Peak Technology Co., Ltd., and holds senior management positions. There is also Tsinghua Macquarie Master of Applied Finance, which can connect university students as teachers.

Hash Capital where Chen Manli works - background introduction

Hash Capital is a digital asset investment research institution co-founded by Mr. Deng Deyan and Mr. Nick.Fu (Fu Xiaoming). The founder, Deng Deyan, holds a master's degree in applied finance from Tsinghua Macquarie. He was a foreign exchange analyst at a well-known Australian financial institution and has many years of experience in securities foreign exchange and spot trading. Mr. Fu holds a bachelor's degree in Law from Renmin University of China and Communications Engineering from Wuhan University of Technology.Bachelor of Science.

Hash Capital and Asia-Pacific Blockchain Business Applications

Hash Capital has raised 3 funds since its establishment, totaling tens of millions of dollars, focusing on the Asia-Pacific market Blockchain business applications and digital asset-related projects. The projects invested by Hash Capital have gradually formed a coverage of the entire blockchain industry chain, including smart contracts, securities transaction settlement, identity certification, distributed accounting, e-commerce, data API and blockchain infrastructure and other fields. Investments include IPTChain, KTrade, Loopring, Qcash, CoinMeet, Halal Chain, Nuls and many other high-quality digital assets.

Comments on mutually reinforcing each other:

Long titles are normal among project founders. After all, blockchain projects do not necessarily require an actual company, and a chocolate office like the Newton project is acceptable. How founders make themselves known to investors is a problem. Therefore, the founders of each project party will have separate titles. People who have experience leading projects are more likely to win the trust of investors.

Create a conversation that is not a joke:

"What do you have?"

"I have a Title."

This shows the importance of titles in the blockchain industry. Dialogue is dialogue, and the founders of the project are still very capable and have professional knowledge background.

From the perspective of covering the entire investment industry, it gives people a professional and grand feeling. It is such a tall-looking organization that hides Chen Manli, the manipulator behind the Hero Chain Entertainment Chain.

Being like a rat with Peking University on your back—difficult!

Why do Chen Manli and other small capitals like to station themselves in Gaofu and sugar-coat things? !

Peking University has administrative status and potential value in the consciousness of the Chinese people

When talking about Peking University, do you feel the same inexplicable heat in your chest as I do now? You have not received its blessings, but you seem to have received them. Surrounded by great benefits. I want to say more but I'm afraid I won't be able to say enough. Peking University Peking University adheres to the principle of freedom of thought and embraces inclusiveness. Probably because Peking University belongs to the Chinese people, not you and me.

1. Taking Peking University as an example, its administrative status makes it more than just an institution

.

Peking University once held the status of the capital, starting from the position when Peking University was founded. By definition, it is the only school established as the country’s highest institution of higher learning in modern China. Initially, it was also the country's highest educational administrative agency, exercising the functions of the Ministry of Education and overseeing national education.

It can be seen that the administrative functions of Peking University have historical origins.

Even if you and II don’t remember, I think he was just an ordinary student or teacher. But some things are really subtle, and many people and rural parents have a brand-like influence on their subconscious minds, just like the widely spread Nainai Temple.

2. Even if the Chinese people’s feelings about the Peking University and the Qing Dynasty are not deep, they are not shallow either

As a normal Chinese child when I was a child, I believe that everyone was the same. In childhood, I must have been instilled with different cultural backgrounds. But the same meaning was expressed in the eulogy of Peking University, Qingda University, Renmin University of China and other Beijing universities. It is undeniable that I also have feelings for Peking University and Qing Dynasty. These feelings are often for people because the masters gave speeches at Peking University. I don’t have many impressions of Peking University, but it’s not shallow either. This influence was so great that when the top scholar in science in Sichuan Province wanted to describe himself as a three-dimensional person rather than a learning machine, he still chose to write "Peking University is my beautiful and shy dream". In human terms, it was for Peking University. As a PR person, I am well aware of the issue of Peking University’s status in the hearts of Chinese people.

Therefore, it is understandable that Peking University is uneasy at this moment.

She, Chen Manli, is still the same, with the same appearance, a teacher title on her head, and the Global University Blockchain Entrepreneurship Leaders Alliance (the launching ceremony of the Global University Blockchain Entrepreneurship Leaders Alliance is July 25 From 14:00 to 16:00 in the afternoon, the Blockchain Leaders Event (Blockchain Leadership Event) Consulting Mentors was held in Room 601, Building C, Mingde Building, Renmin University of China, No. 59 Zhongguancun Street, Haidian, Beijing, once again targeting students from Peking University and other universities.

If today’s entrepreneurial teachers and students hold Peking University’s back and want to be like a rat, it’s hard!!!

Because of the rat shit in the Beijing University, Liang Hongzhi, Shi Ping, Zhang Zongxiang, etc. Aren't they just ordinary people? !

If you ask some old alumni of Peking University who are also managers, are they involved in blockchain? Is it true?
