The blockchain became legal on February 15
As of May 2020, blockchain and digital currency are illegal in China
according to the announcement of the people's Bank of China Central Network Information Office, Ministry of instry and information technology, State Administration for Instry and commerce, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing the risks of token issuance and financing, Article 2 no organization or indivial shall illegally engage in token issuance and financing activities. Organizations and indivials that have completed the token issuance and financing should make arrangements such as refund, reasonably protect the rights and interests of investors, and properly handle risks. Relevant departments will seriously investigate and deal with the activities of token issuance and financing that refuse to stop and the illegal behaviors in completed token issuance and financing projects
Article 3 strengthen the management of token financing trading platform
from the date of this announcement, any so-called token financing trading platform shall not engage in the exchange business between legal currency and token and "virtual currency", and shall not buy or sell token or "virtual currency" as a central counter party, and shall not provide pricing for token or "virtual currency" Information intermediary and other services P>

"illegal financial institutions and illegal financial business activities ban" stipulates that:
eleventh, the criminal suspect, funds and property involved in illegal financial institutions and illegal financial activities, and the public security organs shall take compulsory measures according to law to prevent suspect from escaping and transferring funds and property. p>
Article 12 the people's Bank of China shall, after investigation and confirmation, make a decision to ban the illegal financial institutions and financial business activities, declare them illegal, order them to stop all business activities, and make an announcement
Article 13 if the people's Bank of China discovers that a financial institution opens an account, handles settlement and provides loans for an illegal financial institution or illegal financial business activities, it shall order the financial institution to stop the relevant business activities immediately. No unit or indivial may use the relevant funds without authorizationChinese Mahjong: the world's earliest blockchain project
first of all, a initiates an application. I want to play mahjong and set up a mahjong Bureau, which is equivalent to creating a block, and this block will be broadcast to B, C, D, a, B, C, C, C, C, C, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D, D D...
in the process of playing mahjong, the above four people constantly play cards, which can be understood as mining, through what to mine? Mahjong machine can understand the mineralization machine. These four miners are the so-called miners. These four miners collide from 144 mahjong, and any right card can be Hu card. We can understand the 144 mahjong as a series of hash values (numbers). The process of Hu card is called computational power. Until Hu card, it means that the right hash value is collided and you can get a reward, Each person will pay the corresponding chips to C and put them in the blockchain. The reward is bitcoin or other virtual coins
Why do the other three people take the initiative to reward C? That's because these people have automatically reached a consensus that C has indeed won, and everyone has recorded the account, including the family members who are sitting next to buy horses. It's not good to deny it, otherwise when it comes out that the character is not good, no one will play with him again. After all, the circle is very important
when we reached a consensus, we didn't see any intermediary or third party judging that C had won, and the rewards given to C didn't need to be transferred to C through the third party. All of them were direct point-to-point transactions. This process was decentralization. The card players (miners) recorded their own achievements in the first game, and the third team won the first game, After the record is completed, a complete block is generated. But remember, this is only the first round. In the whole blockchain, this is just a node. The first eight rounds are finished, that is, eight nodes (blocks). Eight blocks are connected together to form a complete account book, which is the blockchain. Because everyone has one account book, it is a distributed account book. The purpose is to prevent someone from tampering with records. In the end, it is clear who wins or loses.
Blockchain itself is not illegal, but if it is used illegally, it is illegal
Li Bin, deputy director of Chongqing big data application and development administration, said that as a disruptive innovative frontier technology in the field of big data intelligence, the Chongqing municipal government attaches great importance to active layout, and the municipal government and Yuzhong District Government jointly build a blockchain base. In the second half of last year, the government issued the opinions on accelerating the cultivation and innovative application of blockchain instry, It has officially launched the construction of a place for strategic innovation of blockchain
while actively encouraging the technological progress and instrial development of blockchain, we will resolutely prohibit the illegal use of blockchain technology in accordance with the requirements of relevant national policies
at present, China's blockchain technology and application continue to innovate, and are graally applied in supply chain finance, credit reference, proct traceability and other fields, with huge development space. As a new technology, if blockchain wants to realize large-scale practical application, it must strengthen the cooperation of instry, University, research and application, and promote the continuous development and maturity of technology and application
since 2017, the development of blockchain technology has aroused the deep concern of the government, enterprises and other sectors. Because of its decentralized, tamperable and traceable characteristics, blockchain attracts investors to add weight to this new technology field. For the previous hot speculation of blockchain technology, the cognition of it and investment circles has become increasingly rational

on April 9, 2017, Hangzhou municipal government and a company jointly set up a $10 billion xiongan global blockchain innovation fund, which can promote the development of blockchain projects. This initiative has also attracted the attention of many relevant financial people. At present, Hangzhou blockchain Instrial Park is one of the important initiatives funded and developed by the municipal government, I believe this case has also become one of the representative cases in China. Since then, more and more blockchains have developed all over the country<
at present, China has a new understanding of digital currency, analyzing the value of digital currency in essence, and relevant departments are also actively participating in the corresponding research. The central bank has set up a special research group and digital currency Research Institute, hoping to further explore the digitalization of sovereign currency. From the side, it can be seen that China has a positive attitude towards blockchain technology, and the Chinese government has repeatedly stressed the important role of blockchain technology in reshaping the global financial pattern
with the development of global economy, the Chinese government has realized the commercial development of domestic blockchain projects. From the blockchain projects invested by Hangzhou municipal government, it can be seen that more and more provinces will start to carry out blockchain projects in the future, which can promote the development of local economy
is blockchain legal in China? At present, the Chinese government is actively studying blockchain, and has carried out blockchain related projects in some provinces. Through the above introction, I believe that people should have a certain understanding of the blockchain. I believe that in the near future, there will be more and more blockchain projects, which can promote the development of domestic economy and enable more and more people to get more wealth from blockchain projects.

this kind of stacking design of eth 2.0 is compatible with its fragmentation chain structure. By setting the fixed mortgage number of 32eth compulsorily, the number of nodes in the whole network is relatively large, and the head node with huge mortgage number will not have monopoly accounting control right in a fragmentation chain, Therefore, the degree of decentralization of eth 2.0 mining will be improved to a certain extent
the second difference: principal and income are not one kind of currency, which can not be traded in the early stage
except for ontology, vechain and other al currency structure design projects, generally speaking, stacking mining is "lock what currency, earn what currency", but eth 2.0 locks eth token on the main chain of pow, and the income released is Beth token on the beacon chain. They are essentially two kinds of currency. Because the two chains will not be interconnected soon, the transaction prices of Eth and Beth in the open market will not be exactly the same
at stage 0, which is expected to go online next year, ETH 2.0 will not have the trading function. Even if the verifier (node) withdraws from staging, the principal and income can not be transferred out of the account. Therefore, all the principal and income of the early participating nodes are almost locked. We can only wait for the further development of eth 2.0 to graally realize the account trading function
the third difference: in the early stage, there was no decentralized entrusted mining
the function of "entrustment" can separate the token from the block right carried by the token, and the token holder can entrust the block right to trusted nodes to participate in consensus and win awards on behalf of them, which is also the reason why stacking is widely known by the public and is becoming popular. However, in the first two phases of eth2.0 (phase 0 and phase 1), there is no decentralized entrusted mining, which means that the coin holder can only set up its own node to run, or hand over the coin to the centralized mine pool to mine on behalf of it. However, agent mining is equivalent to transferring the coin to someone else for trusteeship, which has the security risk of capital
secondly, we need to understand the participation conditions of Ethereum staging
the participation threshold of Ethereum staging is not very high. In terms of hardware, the performance of home computer can run a node. Ethereum hopes to encourage more money holders to participate through low threshold, so as to achieve the goal of decentralization as much as possible
because the coin holder is not a professional node operator, it is generally unable to guarantee the 24-hour operation of the node. Therefore, in the design of the economic model, the penalty of Ethereum stacking for the node offline is very small, about 1% for three consecutive days, but the longer the offline time is, the greater the penalty will be, and 50% for 21 days offline
for the participants, 24-hour operation of the node can ensure the maximum revenue. At the same time, it is also necessary to do a good job in node version upgrade, prevention of "double flowers", fault monitoring and disaster prevention. At that time, some node operators will launch professional node operation services
after understanding the above information, let's take a look at the revenue analysis of Ethereum stacking
the annual SEO rate of eth 2.0 changes dynamically with the whole network pledge rate. According to the published rules, the relationship between the annual SEO rate and the whole network pledge rate is 0.5 power. The higher the pledge rate of the whole network, the higher the annual additional issue rate, and the lower the annual return rate of a single node. When the whole network pledge is 10%, the annual yield of the node is 5.72%.
Blockchain is a kind of network with data; Hash Verification & quot; The purpose of the functional database is to verify the effectiveness of information, which is generally applicable to finance, insurance, public welfare, public services, mobile communications and other fields. Therefore, in recent years, many criminals have focused on the blockchain for online gambling to seek huge benefits. In January 15, 2021, the Jianhu police in Yancheng successfully cracked the first case of gambling in the country using block chain contract technology, and arrested 11 suspects, and the number of gamblers reached as high as 7.3 million. The funds involved were as high as 8 billion yuan , involving 17 countries and regions. p> In October 2020, Jianhu police received a clue that there was a new one on the public chain of grapefruit coin called & lt; Biggame” Grapefruit is a digital currency issued by foreign organizations, which is allowed to be used in public blockchain. There are more than 10000 people participating in this gambling app every day, and the daily bet amount is more than 10 million yuan. The way to participate in gambling is our common fruit machine, Red Black War and so on
have you ever been led to participate in virtual currency gambling
