Ⅰ What should I choose for the question Civil Servant? More and more people have become blind followers of the Internet trend. They are afraid that their usual virtual identity will be exposed on a certain network

You Well, civil servants and major Internet companies are both good choices. It depends on personal wishes.

1. Choose between civil servants or Internet companies

Among the major Internet companies, Tencent’s work intensity is at a medium level.

The halo of big manufacturers is high, while the base of the same level is relatively lower. Tencent's 75 general contracting job can break through to Kuaishou Byte and an Internet company like Pinduoduo, which can break 100. It is not a big problem to change jobs and go to Microsoft Research Asia to get a 50 RMB general contracting job. Microsoft is 965, work life balance.

Programmers from large factories who meet 1 of the above 4 points can consider "hometown" or "hometown capital" or "work place" or "Guangzhou, Shenzhen, Hangzhou, Ningsu" For civil servants, people from Zhejiang can additionally consider Ningbo, people from Jiangsu can add Xichang, and people from Guangdong can add Foshan Wanzhongzhu. To be honest, I don’t recommend the rest. Stay tuned to learn more.

The 2020 "5G Applications and New Internet Infrastructure" report pointed out that technologies such as 5G, cloud computing, big data, and blockchain have become important representatives of new infrastructure. At the same time, IT technical talents are also the IT technical talents that major Internet companies such as Tencent, Alibaba, and Huawei are competing for. It can be said that they are the current hot spot and are not inferior to civil servants.

I hope my answer will be helpful to you!

Ⅱ What is blockchain, what is consensus, and what is currency circle

Blockchain is an encrypted information transmission with distributed accounting and decentralization as the core. Distributed accounting means the right to exist that cannot be destroyed, and decentralization means the right to independent transmission that cannot be tampered with. The two together are defined by Qingquan as "indestructible."

However, the blockchain has weak links, and it is heavily dependent on the network for its existence. Not just on a delivery level, but also on a recording level. The core layer of the blockchain is the physical layer, which is parasitic on the Internet system. If one day the Internet around the world is forcibly suspended, then the independent system of the blockchain will also fall into a state of suspended animation.

However, this kind of suspended animation is not real death, but requires some kind of systematic key to activate. Is there such a systematic key now? some.

Consensus comes from cognition.

Anyone with a little common sense in economics knows one thing clearly: legal currency is worthless! In fact, from the beginning of the forced decoupling of the British pound from the metal standard to the collapse of the Bretton Woods system, the legal currency of any country in the world is de facto valueless. The so-called purchasing power of legal currency is guaranteed by administrative coercion, but this administrative coercion is often abused. Therefore, the Guanjin volume we once saw in textbooks is returning to the world's economic tide, starting from the US dollar. QDI quantitative easing to China’s monetary policyThe actual meaning of "appropriately loose" is that the money printing machine will work overtime.

However, the money supply is subject to an offer from the total supply and demand of society. Within the scope of this offer, the face value of the currency is still guaranteed. Once it deviates from the For this offer, the currency needs a "reservoir". I once said that the concepts of the U.S. stock market and China's real estate market are the same in the economic sense. Of course, there are also those who dare not spend money.

Legal currency must be devalued. This concept involves more advanced economic knowledge, and even thirty chapters cannot be completed here. Depreciation within a certain range is beneficial to the development of human society, but this certain range is often abused. This comes from the weakness of legal currency itself - administrative coercion. But administrative coercion cannot defeat human nature.

Therefore, since the emergence of the blockchain, people with foresight have begun to try to defeat the depreciation of legal currency by assigning value to the blockchain. As a result, we have also seen that from that piece of pizza until now, we are still seeking to assign value to the blockchain.

Is this all the consensus is? no.

In the process of the development of blockchain technology, various algorithm differences have emerged, such as sharding, encryption, storage, running speed and network carriers, which are the coins we see now. This phenomenon is essentially a "split of consensus", but there is no way to do this, because although BTC is the originator, it does not meet our needs for the blockchain in terms of value assignment. He is too slow, too old and too young to withstand the impact of legal currency. In the economic sense, BTC is now defined as a luxury product rather than a digital currency, because when studying the match between its value projection curve and the economic tide, it was found that it is surprisingly similar to luxury goods.

The currency circle is the bud formed by the mutual dissolution of blockchain development assignments and legal currency. In essence, the existence of the currency circle is the inevitable amplification of blockchain consensus. The currency circle is not the whole of the blockchain, it is just A flower for which we still expect fruit.

What is our ideal blockchain application?

When the utility of legal currency is unbalanced due to some kind of force majeure, we can use the independent system established by the blockchain for value exchange. But it is a pity that the utility of legal currency is not unbalanced, but this value exchange system has entered the economic cycle prematurely. The most notorious one is the dark web, and there is also the "money laundering" that haunts us all the time. This gives the currency The circle was shrouded in a layer of sadness.

It must be pointed out that even the above value exchange is not what Qingquan believes.The definition of value exchange is to use the consensus of the blockchain to serve as a medium for legal currency interoperability. The background of the blockchain is far from this.

The real blockchain should be a useful supplement and adjustment in the normal legal currency economic cycle system, and should also be a replacement when the normal legal currency economic cycle system fails. Although we don’t want to think about it that much, I really don’t want to see the situation of carrying a large bag of banknotes in exchange for two pounds of potatoes.

However, is the current currency circle ready for this? not yet! The current currency circle only believes in the four-year cycle but has abandoned the original appearance of the blockchain. Some people even use these coins, these technologies, and these consensuses as tools of deception and fraud. This is the tragedy of the entire human society!

Talking about trading, there have been countless cases of getting rich in the currency circle, which has given Leecai the illusion that "Maybe that person will be me". Playing with spot products, I can't stand the loneliness and it is slow to make money. Playing with contracts is even more difficult. Needless to say, it is the same as gambling. Anyone who has been trading in this circle for huge profits has never seen anyone not losing money.

Ⅲ The operating principles and principles of blockchain Development, you have to know!

1. Why is there innovation in blockchain?
The starting point of the first generation of the Internet is the TCP/IP protocol, which implements a unified format for peer-to-peer transmission of information by all nodes on the network. Open code. However, the impact of such an uncomplicated innovation on mankind is epoch-making. It has programmed, agreed, and enforced the basic values ​​required by a unified global market: "freedom, equality, and fraternity." Then the STMP email protocol, HTTP domain name protocol, etc. were derived, achieving low-cost and high-efficiency global information transmission in a decentralized manner. As Alibaba Vice President Gao Hongbing said:
"The Internet is to eliminate the (information) supply chain that has very low value and high cost - it is open, interconnected, peer-to-peer, globalized, and decentralized."
We know: The essence of the market is also decentralized. It automatically executes the decentralized agreement of "equivalent exchange". Just as Nobel Prize winner Ronald Coase summed up: "The market economy is based on two On the basis of deep cognition: admitting ignorance and tolerating uncertainty." Adam Smith also described the market as: "the invisible hand"! Therefore, the market must require the low-cost flow of information decentralization, and the Internet has adapted to the global Under the general climate formed by the unified market, it turned out to be.
However, the first generation of Internet decentralized solved the problem of low-cost and efficient transmission of information, but it did not solve the problem of credit of information. Therefore, what the second-generation Internet must break through is: how to establish global credit in a decentralized manner so that value transfer can be carried out at low cost and with high efficiency.
Then the original centerWhat are the problems with a centralized credit system? As we all know: centralized credit, such as the legal currencies of various countries, has different credit values ​​and incompatible clearing systems, which adds a lot of cost to global trade. The current global credit system centered on the US dollar has a "Triffin Paradox" in its mechanism (the essence is that a country's legal currency cannot simultaneously resolve the conflict between its own economic interests and global economic needs). Therefore, in 2009, the Governor of the Central Bank of China, Zhou Ogawa called for the creation of a super-sovereign storage currency. In the same year, Satoshi Nakamoto disclosed the first-generation blockchain source code-"Bitcoin" online.
2. How does the blockchain system operate?
First of all, Satoshi Nakamoto knew very well that establishing a credit system for payment must solve the problem of preventing "duplicate payments", that is, no counterfeit currency can be created. The centralized credit system relies on state machinery to prevent counterfeit currency. What about "Bitcoin"? Satoshi Nakamoto's great innovation is to "timestamp" every transaction. There is a block (block: equivalent to a network account book) every ten minutes, and all network transactions for these ten minutes are correctly timestamped. The question is who will cover it? Satoshi Nakamoto did not assume that everyone on the Internet is Lei Feng. He agreed with Adam Smith: people in the market are greedy. He asked the so-called "miners" to compete for the accounting rights of these ten-minute blocks. The rules of the competition were to correctly record the accounting while solving the SHA256 problem. Who can prove that their computer has the fastest computing power (the so-called PROOF OF WORK mechanism), he can compete for the legal accounting rights of these ten-minute blocks and get a reward of twenty-five bitcoins. This is the so-called "mining" process. It is actually a decentralized credit process that establishes a network-wide ledger - the blockchain. Therefore, the more essential function of miners is "bookkeepers"!
Satoshi Nakamoto is here In its Bitcoin white paper, the process of establishing this credit system is described in detail:
Step 1: In order for the entire network to recognize it as valid, each transaction must be broadcast to each node (node: that is, the miner);
The second step: Each miner node must correctly timestamp each transaction in these ten minutes and record it in that block;
The third step: Each miner node must Compete for the legal accounting rights of this ten-minute block by solving the SHA256 puzzle, and strive to get a reward of twenty-five bitcoins (fifty bitcoins every ten minutes for the first four years, decreasing by half every four years);< br>Step 4: If a miner node solves the SHA256 puzzle of these ten minutes, it will publish all the timestamped transactions recorded in its ten-minute blocks to the entire network, and they will be checked by other miner nodes in the entire network;< br>Step 5: Other miner nodes in the entire network check the correctness of the block accounting (because they are also stamping the accounting at the same time, but they have not competed for the legal block accounting rights, so there is no reward), there is no error Finally, they will compete for the next block after the legal block, thus forming a legal accounting block single chain, which is the general ledger of the Bitcoin payment system - the blockchain..
Generally speaking, each transaction must undergo six block confirmations, that is, six ten-minute accounting, before it can finally be recognized as a legal transaction on the blockchain. The following is the accounting format of Bitcoin:
So the so-called "Bitcoin" is such a billing system: it includes the owner electronically signing with the private key and paying to the next owner, and then the entire network's "miners" "Time stamp the account and form a blockchain.
3. What are the innovations in Bitcoin’s blockchain finance?
Similar to gold, trying to establish decentralized credit on the global Internet may allow value to flow across the entire network at high speed and at low rates (currently each transfer The transfer rate is one ten thousandth);
The total amount of currency is agreed upon by the cryptographic protocol;
Compared to gold, digital currency is infinitely divisible;
The value of currency can be based on a large number of P2P transactions ;
Full transparency in financial management (every transaction can be traced on the blockchain).
Bitcoin’s blockchain-wide accounting system has established a market value of US$10 billion, the highest on the global Internet. Therefore, Wu Xiaoling, dean of Tsinghua PBC School of Finance, pointed out: The blockchain experiment established distributed credit, which is an upgraded version of Internet TCP/IP, upgrading from information transmission to value transmission;
4. Bitcoin’s blocks What are the inherent flaws of the chain system?
Bitcoin’s blockchain system has had successes since it was open sourced on the Internet in 2009, but it also shows some inherent flaws that are difficult to overcome:
The total amount cannot be adjusted at any time As the market situation changes, it will inevitably rise and fall sharply;
Mining is high-carbon. Only less than 1% of miners can compete for the accounting rights of blocks of less than ten minutes, and more than 99% of other miners participating in the competition have the computing power. Waste;
The annual inflation of about 10% has greatly increased the cost of the Bitcoin financial ecology, and even threatened her survival;
As a decentralized self-organizing DAC system, the operating costs of the accounting and issuance functions are too high high.
As a global payment system, its efficiency is far from meeting the actual requirements of global trade. The Bitcoin network currently confirms a maximum of 7 transactions per second. In comparison, Visa's network system can process 10,000 transactions per second at the fastest, and Alipay's record is 80,000 transactions per second on Singles' Day in 2014!
5. Block The development of chain technology 2.0:
As the 2.0 upgrade and development of blockchain, it first focuses on solving the high-carbon mining of Bitcoin accounting:
When we discuss how to overcome the high carbon of Bitcoin mining and accounting Professor Liu Taoxiong from the Tsinghua Institute of Economics pointed out that mining competition relies on computing power. In the end, only one company competes for the legal accounting rights, and the other 99% of the miner nodes are mined for nothing, which is a waste of resources. It is obviously unreasonable. If The whole network transparently knows the legal accounting rights of the next block, and it is randomly generated in the entire network, which eliminates the high carbon cost of competitive accounting! After hearing this, we all praised Professor Liu for his brilliant idea, because the second generation is now more successful. Coin NXT has this kind of mechanism. Their white paper is called "Transparent Forging", which is just an accounting right.The probability of winning is directly proportional to the NXT token holdings in each miner node wallet. This is called the Proof of Stake mechanism (PROOF OF STOCK). Of course, this also triggered a debate about the unfairness of NXT’s distribution of tokens to early investment developers!
RIPPLE is a semi-decentralized blockchain solution that uses “trusted gateways” to conduct block operations. The credibility of chain accounting is based on the consensus ledger protocol that these gateways will not do evil at the same time.
The most ambitious attempt is Ethereum, which combines blockchain technology with Turing completeness, hoping to develop a basic platform that can support the construction of various blockchain systems in the future. The development of various credit currencies, digital assets, smart protocols and even financial derivatives. The system design is to unify blockchain accounting on the ETHERUM platform and be used by all developers. Maybe their official version will be released in the near future.
6. Possible applications of blockchain innovation in other fields:
Now, blockchain’s attempts to establish decentralized credit are no longer limited to the financial world, but have attracted attention from all fields of society, especially in At present, some of China's central credit institutions, such as the "Red Cross", are in a "collapse" situation. Blockchain can provide a new way of thinking and technical options for social management. The following are some new developments and related discussions we have learned about:
The combination of blockchain and the Internet of Things unifies digital assets and atomic assets, smooths the difference between consumer assets and cash assets, expands public credit, and accelerates value circulation; (IBM-Samsung)
Built on the blockchain Intellectual property protection system, accounting for the use of intellectual property across the entire network, and establishing a global advertising market;
Whether blockchain can provide technical support for the issuance of protocol-based cryptographic currencies in emerging economies along the Belt and Road;
Block Chain + cloud computing can develop into a decentralized self-media and community system;
Blockchain can build a decentralized equity crowdfunding system, allowing innovative projects to enter the circulation field in advance;
Blockchain can develop Develop a fully transparent financial management system;
Blockchain supports the establishment of a global decentralized corporate organization.
In short, in this era when credit has become a scarce resource, the technological innovation of blockchain, as a distributed credit model, can provide new solutions for finance, social management, talent evaluation and decentralized organization construction in the global market. All provide a broad development prospect.

IV How is the life of the man who asked others to buy Bitcoin on Zhihu 7 years ago?

"Force Field" - Public Chain Mining Mine First Community

On December 21, 2011, a girl asked on Zhihu, "A junior student has 6,000 yuan on hand. What are some good financial investment suggestions?" On that day, Babbitt founded Ren Changchai replied: “Buy Bitcoin and keep your wallet files.file, then forget that you ever had 6,000 yuan, and look at it again in five years. ”

From 2011 to 2018, Bitcoin soared from US$3 to the highest point of US$19,000. If that junior student had bought all 6,000 yuan in Bitcoin, it would have already been A net worth of tens of millions. The Zhihu girl who missed out on Bitcoin said she regretted not listening to Chang Chai’s advice to buy Bitcoin. In an exclusive interview with Shenlian Finance, Chang Chai also said she regretted answering such a question.

“If I were to give her one more piece of advice, I would definitely not recommend investing in Bitcoin. " Changchai told Shenlian Finance. "Putting your happiness on the advice of an irrelevant person is not laziness, but stupidity. ”

1. The civil servant who asked people to buy Bitcoin

In 2010, Liu Zhipeng, who graduated with a graduate degree, entered the Land and Resources Planning Institute of the Guangxi Zhuang Autonomous Region and became a civil servant. Here, he participated in the publication of several academic papers on the mineral resources of the Beibu Gulf Economic Zone.

In addition to writing these academic papers, Liu Zhipeng also participated in social platforms such as Zhihu and Weibo. In Zhihu Recently, a netizen asked: A junior college student has 6,000 yuan on hand. What good financial investment advice is there? "Buy Bitcoin, save the wallet file, and then forget that you have 6,000 yuan. Look at it again in five years." . "Liu Zhipeng gave such advice. However, he did not use his real name. Instead, he used the name "blockchain", which was confusing at the time. Later, the word was translated as "blockchain" in China.

Liu Zhipeng had many pseudonyms. When he wrote science fiction novels, his name was "Chang Chai", which comes from "Li Sao" "Lu Lixi with the Chang Chai, Cui Wei with the crown cutting the clouds". Before becoming a civil servant, Liu Zhipeng had already He was well-known in the field of science fiction novels and had won several awards. However, becoming a civil servant seemed to indicate that writing science fiction novels at that time was not a good way out. Later, the name "Chang Chai" accompanied Liu Zhipeng, and he became famous in the science fiction circle. Moved to the currency circle, his reputation is growing, which is due to the rise in the price of Bitcoin.

Just like his answer on Zhihu, he has become the most popular person in the currency circle since 2013. One of the most talked-about topics, with nearly 30,000 likes and more than 6,600 comments. Even now, many people still leave comments under this answer to watch the fun, lamenting the fleeting opportunity for wealth, and praising the greatness of Changchai. Great God.

In fact, Chang Chai has recommended Bitcoin to strangers on Zhihu more than once. Among his 118 Zhihu answers, there are a total of four answers recommending Bitcoin. Has anyone listened to Chang Chai? We don’t know whether Zhihu recommends buying Bitcoin, but what we can confirm is that some people have made their first pot of gold in life because of Zhihu.

In 2011, Zhang Ming had just passed the entrance examination Henan FinanceAt the University of Economics and Law, I accidentally discovered an account named Blackbeard Bitcoin while browsing Weibo. Since I usually like the anime One Piece, and Blackbeard is a character in it, Zhang Ming took another look at this Weibo account. .

In this Weibo, Zhang Ming learned about the existence of Bitcoin for the first time and was immediately attracted to it. After a period of research, during the Spring Festival of 2012, Zhang Ming spent 3,000 yuan of his lucky money to buy Bitcoins from Bitcoin China. “The price of Bitcoins was very low at that time, $5 each,” Zhang Ming told Shenlian Finance. The return on investment was huge. In Zhang Ming’s own words, he just wanted to see if he could make money to buy a mobile phone. As a result, he earned back all four years of college tuition.

Since then, Zhang Ming has been investing in cryptocurrency. While other classmates still rely on the living expenses provided by their parents, Zhang Ming has made millions of yuan in the currency market. It was not until later that Zhang Ming learned that Blackbeard Bitcoin was the Weibo account used by Chang Chai to promote Bitcoin, and it was also his nickname on the Babbitt Forum.

When asked why he recommended Bitcoin on Zhihu, Chang Chai said: "Based on a very simple motive, it is to let more people know about Bitcoin." When writing that answer, Changchai is certain that Bitcoin will definitely rise a lot in the future. The charm of history is: when you look back at the ending, you will see a destined path. It is clear at a glance at which node everyone's destiny met and what changes occurred.

However, at that time, no one could know what the fate would be. After recommending strangers to buy Bitcoin, Liu Zhipeng continued to do his job at the Guangxi Land and Resources Department day after day. In 2013, he and 55 other colleagues obtained the professional technical qualification as an engineer.

2. Wu Jihan gave me my first donation

Chang Chai’s ambition is not in the geological industry. He also has many hobbies, such as writing novels and researching cryptocurrency. But in his own opinion, the number of readers of his novels may not be as high as the number of likes on that Zhihu answer. Chang Chai published his first novel in "Science Fiction King" when he was 16 years old. In 2004, he published his first novel in "Science Fiction World" under the pen name "Chang Chai". In 2006, 2007 and 2008, it won the "Galaxy Award", China's highest science fiction award, for three consecutive years. Hugo Award winners Liu Cixin and Hao Yufang are also regular recipients of the Galaxy Award.

To this day, many book fans still mention Chang Chai and his works on social platforms. If he continues to write, we don’t know whether Chang Chai can become the next Liu Cixin, but in Chang Chai’s view, Bitcoin has opened another door to “science fiction” for him.

In 2010, Chang Chai was obsessed with science fiction novels and paid attention to Bitcoin because of his creative needs. As early as 2008, Chang Chai wrote an article titled "Slaughter"In the science fiction novel "Dragon Technique", the protagonist is also a hacker, Anonymous. He controls the cloud computing resources on the Internet to help him complete grand computing projects. The concept of "computing is power" coincides with the idea of ​​Bitcoin.

Therefore, when reading the Bitcoin white paper, Chang Chai had a feeling that "the future is already here". At that time, it was the first wave of Bitcoin’s collapse. The titles of media reports were very scary, such as “Bitcoin’s past and present life”, “Bitcoin is dead” and so on. There were mourners everywhere, and they all seemed to be giving eulogies for the final conclusion of Bitcoin. But in Chang Chai's view, these reports are ridiculous. "What others see as a black swan is a gray rhino in my eyes, an opportunity with a high probability of success."

In 2010, Chang Chai I bought my first Bitcoin through Taobao. Recalling the experience of buying Bitcoin at that time, Chang Chai still finds it very funny. “Since there was no quick way to buy Bitcoin in China at that time, my first reaction was what to do if I can’t buy it, and what to do if foreigners don’t sell it. So I told the shop owner that I must Leave the goods for me." While working at the Guangxi Land and Resources Department, Chang Chai had been paying attention to the dynamics of Bitcoin. At that time, the foreign Bitcoin forum bitcointalk was well-known in the circle, but there was no similar website in China.

In 2011, Chang Chai, who had experience in running community websites in college, founded Babbitt, which was China’s first blockchain forum and also Chang Chai’s subsequent entrepreneurial direction. At that time, information about blockchain on the Internet was very scarce. Chang Chai worked tirelessly to translate information and posts from English websites and sent them to Babbitt. His Bitcoin address was also left on the website. One day, a person left a message under the article and said, "Blogger, I think your website is very good. Why don't you apply for an independent domain name and space? I donated 0.168 BTC from your address." People who knew Bitcoin at that time were like As rare as giant pandas are, it is even more difficult to meet people who can exchange Bitcoins in life. Chang Chai is very pleased by the messages and donations from strangers.

After adding the other party’s QQ, Chang Chai learned that the person’s name was Wu Jihan, who was later the founder of Bitmain, an internationally renowned mining machine manufacturer. At that time, Wu Jihan was the bitcointalk Chinese The moderator of the forum. From 2011 to 2014, Changchai maintained a life of working, running Babbitt, and conducting Bitcoin evangelism on Weibo, Zhihu and other platforms. Getting further and further away from science fiction and getting closer and closer to Bitcoin.

“I followed Changchai because I liked science fiction and became a friend of Renren. Around 2011, he talked about the future of Bitcoin on Renren all day long. I thought to myself, how could this person? It’s like following a pyramid scheme.” A friend of Changchai’s Renren told Shenlian Finance.

3. I regret advising others to buy Bitcoin at that time

"I am going to promote Bitcoin with my true identity. This Weibo will no longer be updated. I will inform you all of the new ones later.address. "At the end of April 2013, Chang Chai was transferred from the Weibo account "Blackbeard Bitcoin" to the Weibo account "Chang Chai". The Weibo avatar is an armored warrior riding a horse, with the warrior's right hand holding a spear. , holding a shield in his left hand, with the "B" representing Bitcoin written on the shield.

Since then, the pseudonym "Changchai" has been transferred from the science fiction circle to the currency circle. In the same year, Changchai became famous in Zhizhi Hushang gave three other strangers advice on buying Bitcoin, but it didn’t attract much attention. This year, Bitcoin repeatedly broke new highs and reached a record high price of $1,242 at the end of the year. At this time, gold The price was US$1,241.98 per ounce, and Bitcoin surpassed gold for the first time.

The Zhihu reply in 2011 was also picked up by netizens and circulated wildly on the Internet, but it has never seen any growth since then. Recommend others to buy Bitcoin on Zhihu. “Actually, I regret answering such a question before. "In Changchai's view, because of the myth of getting rich through investment, many people have focused on the speculative effect of Bitcoin instead of the blockchain and decentralization concepts behind it, which is very different from his original intention.

Therefore, Chang Chai never answered similar questions on Zhihu again. Zhihu invited him to participate in several round tables, but he decisively refused.

"If I give her another suggestion, I There is certainly no advice on what to do with Bitcoin investment. Her original choice was the most correct, and poetry and the distance were more important. And I don’t think she won’t regret buying Bitcoin when she bought it. Maybe she will regret it even more. Maybe she sold it when it doubled in price, or she lost money when it dropped? ”

In Changchai’s view, no one can make a lot of money just by hearsay. The most important thing is to invest in your own brain, otherwise the information will not be visible even if it is put in black and white in front of you.

"Putting your happiness on the advice of an irrelevant person is not laziness, but stupidity. ”

IV Please elaborate on the principles of blockchain technology and digital currency development

Blockchain and distributed ledger technology make digital currency development more reliable.
District Blockchain technology has been criticized for disrupting centralized currency exchanges, but its potential to solve the trust and centralization issues of existing information architecture has attracted a lot of attention. Blockchain technology first gained great popularity in the field of Bitcoin and digital currencies. Well-known, it uses a single shared ledger to store information. It no longer allows a single central organization to obtain the ledger, but different nodes in the peer-to-peer network obtain multiple copies of the same distributed ledger. Shenzhen Yuanzhongrui Blockchain Technology , using advanced encryption technology to ensure that any new information in the ledger cannot be tampered with, unless it meets certain preset parameters. Moreover, this ledger is more resistant to external attacks, such as network attacks, because of this decentralized system No costly single failure of centralized information architecturepoint. At the same time, all trusted nodes can affect any modifications to the ledger, provided that certain preset parameters are met. These modifications will be immediately reflected on the ledger, and all trusted nodes can obtain relevant data to make correct decisions. You can also adjust the design of the distributed ledger to create a hierarchical system within the architecture and configure appropriate access rights and different levels of authority.
Blockchain and distributed ledger technology are conducive to changing the way land registration is managed. The real estate market's current credibility is at its lowest, all down to an inefficient and opaque property registration system. The system relies on centralized access to information on land registration and corresponding property transaction activity. Using distributed ledger technology to obtain, manage and modify this information can ensure that the public does not suffer from land transaction fraud. Similarly, distributed ledgers can simplify and integrate corporate compliance processes across industries and regulatory fields because it contains real-time compliance information needed by government departments and third parties such as banks and investors. Implementation of social welfare programs can be better tracked by consolidating data points across multiple programs and providing feedback on beneficiaries' program participation.
The biggest issues in current technology development include: the transformation costs of unique data storage systems, verification of network nodes or data reliability at all levels, the privacy and security dimensions of decentralized data acquisition methods, the Information Technology Act (Information Technology Act). Importantly, blockchain technology will change the way governments interact with citizens, and this dramatic shift is bound to be resisted by civil servants. These are possible problems, and action should be taken immediately to develop a regulatory framework to guide application development in addition to using blockchain technology.
