Blockchain initiator

2. Now let's talk about the feasibility of blockchain equity crowdfunding in China. As we all know, as far as China is concerned, companies fall into two categories: joint stock companies and limited companies
joint stock companies are divided into "listed companies" and "unlisted companies". The shares of a listed company are registered in China securities registration and Clearing Corporation, so its behavior of issuing shares or trading shares is regulated by the CSRC. Here, we don't want to explain more; The shares issued by non listed companies do not need to be registered by any institution, and can be confirmed by issuing shares and maintaining the register of shareholders. Of course, many of them are registered through third-party institutions such as the instrial and commercial department or China Securities Depository and Clearing Corporation, and use the local share custody center to provide third-party registration services for publicity. Moreover, when the company's equity changes, it is necessary to manually process paper equity certificates, option issuance and convertible notes. In this way, the company's stock rights can be changed, The maintenance of the register of shareholders will become very complicated, and the tracking and maintenance of transactions will become more difficult to trace with more and more transactions
if the techshares blockchain technology is used for equity crowdfunding, all the above problems can be perfectly solved. The blockchain account book is safe and transparent, and can not be tampered with. It is also easy to track, and can record the company's equity and its change history at any time
convenience of equity transfer and circulation
for equity crowdfunding, equity circulation is an important part of business, which can stimulate the activity of users and promote more registration and issuance. The traditional OTC over-the-counter equity trading is based on the credit of both sides of the transaction, and the two sides of the transaction bear the credit risk on their own. The transaction can only be carried out after the establishment of bilateral credit, and the trading platform bears the credit risk of market traders
techshares blockchain technology can rece the credit risk of transactions. In essence, it decentralizes the third party that provides credibility to a more thorough extent, that is, it is no longer limited to specific third party entities, but relies on all participants to jointly maintain a set of registration system. On the one hand, blockchain gives the right to record to the company itself, reflecting the spirit of autonomy; On the other hand, it can also ensure the openness, transparency and authenticity of information records, and minimize rights disputes. The ownership of equity is registered in the blockchain, and the equity transaction must be signed by the owner's private key to be verified; After the transaction is confirmed, the change of equity will also be recorded in the blockchain, so as to protect the interests of both parties
how to ensure safety
as an investor, the most worrying problem is the safety of funds. Traditional equity crowdfunding often has the problem of "double flowers" (Note: double flowers - Double expenses, that is, the only share is repeatedly transferred to two people). Until the electronic data is comprehensive, the central clearing agency ensures that the whole system can be leveled after trading. But the risk is often borne by the platform. Unlike traditional floor trading, equity crowdfunding business is carried out by many independent companies. Therefore, these trading activities are scattered on various platforms. With the techshares blockchain technology, the decentralized trust constructed by the blockchain can ensure the normal operation of the system and business without the need for mutual trust. Everyone becomes a node in the blockchain, with their own public key and private key, participating in rapid transaction verification and accounting. Moreover, in the initial stage of equity crowdfunding, the sponsors, crowdfunding platforms, investors and sponsors jointly sign a crowdfunding contract to agree on their respective responsibilities and obligations. The contract can be stored in the blockchain in the form of a smart contract, and the blockchain ensures that the contract cannot be tampered with ring the performance. In this way, there is no need to worry about safe space
it has strong expansibility, reasonable and legal
blockchain equity crowdfunding is composed of three-tier structure, and the bottom layer is blockchain network, which constructs a decentralized trust distributed system; The middle layer is the combination of business logic and blockchain to jointly establish account center, equity registration, equity voucher, equity transaction, equity management and other functions; The top layer is the crowdfunding platform for customer-oriented business, and the business of the platform can be extended to various fields and instries in theory
with techshares' blockchain technology, decentralized trust can be realized by building P2P self-organizing network, orderly and tamperable cryptography account book and distributed consensus mechanism. In addition, no matter the company law, the regulations on the administration of company registration or other laws and regulations, there are no specific restrictions on the form of expression of the register of shareholders maintained by the company itself. The company can choose to create and maintain the register of shareholders in any form with written records, not limited to specific carriers. Therefore, it is entirely reasonable and legal to use techshares as a carrier for equity crowdfunding on the blockchain. Once it is voluntarily chosen by the company, it can provide legal and effective proof for the company's equity (shares).

Recently, MIT announced that it will launch MIT financial technology laboratory with several top technology companies in the world on July 18, 2018. Its main research directions include blockchain development, privacy security, database, encryption system, etc. ant financial is the only Chinese founder

In an exclusive interview with people, Jiang Guofei, director of ant technology laboratory, said that the former NEC technology VP, who has been wandering in Tokyo Bay and New York Bay for the past 15 years, said that China and the United States are almost on the same starting line in the independent research and development of Frontier core technologies such as blockchain, This is a sight that has never been seen before“ Whether it is Tokyo Bay, New York Bay or San Francisco Bay, they all rise in the blowout of Japan and the United States' comprehensive national strength. Now it's time to go to China, so I'm back. "

4. Blockchain is a public account book. You can't say that your natural gas and chopsticks violate the law, because they are just tools
Chinese 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.

5. When someone does something wrong, people's first reaction is to stop him. However, e to the factors of status and timing, sometimes direct check will have the opposite effect
I think the first step is to make sure that your parents are not deceived, because parents may be better at communicating. Then work with your parents to stop your uncle
I think you can find one or two professionals to teach your uncle, such as your teacher, and you can also find the content of online rumor refutation.

If the time is t, the landing velocity is V, and the impact force is f. It can be calculated by the formula ft = MV

objects that fall only under the action of gravity without any resistance are called & quot; Free fall & quot;. An object, such as one that begins to fall from a static state under the action of the earth's gravity. The sky near the earth's surface can be regarded as a constant gravitational field. If the atmospheric resistance is not taken into account, the motion of the free falling body in this region is uniformly accelerated linear motion. Its acceleration is equal to the acceleration of gravity G

extended data:

the main characteristics of free falling body

the characteristics of free falling body motion are reflected in the word "free", which means that the object is stationary when it begins to fall, that is, the initial velocity v = 0. If the initial velocity of the object is not zero, even if it falls vertically, it cannot be regarded as a free falling body

(2) in the process of falling, the object is not affected by any other external forces (including air resistance) except gravity, and the resultant force of external forces is 0

(3) the falling time of any object is the same when it falls freely at the same height

7. On October 22, 2013, Qiao from Dongyang searched GBL company, a bitcoin trading platform, on the Internet, and recharged 90000 yuan to buy and sell bitcoin through a third-party payment. On October 26, Qiao found that the staff of the network trading platform were not online, and some normal trading proceres could not be implemented, and then reported the case to Dongyang Public Security Bureau
Dongyang Public Security Bureau of Zhejiang Province immediately started the investigation and found that Qiao was not the only one who suffered losses. Through efforts, the police of the special task force determined the identity of the manager of the GBL trading platform and implemented the pursuit in time. The first case of fraud on bitcoin trading platform in China was solved
lawyer analysis:
Zhang Yanlai, senior special researcher of China e-commerce research center and lawyer of Zhejiang Jin law firm, believes that virtual currency is not a new concept. Q-coin and online game currency have long been known by people. However, the emergence of bitcoin once again makes people realize the power of virtual currency. Compared with the traditional q-coin, the biggest feature of bitcoin is that it does not have a unified issuing agency. The generation of bitcoin completely depends on computer algorithms, and anyone can participate in the issuance of bitcoin
this makes it difficult to trace the source of bitcoin, which makes it a real virtual currency. The anonymity, cross-border and other Internet genes of bitcoin make people see a new form of currency that may circulate in the future society, so the pursuit and use of bitcoin also continued to rise in 2013. Some foreign governments have recognized the legal status of bitcoin. In China, some online stores have begun to use bitcoin for trading. Restaurants that accept "bitcoin" consumption have appeared in Beijing. The first "bitcoin" investment fund in China is also being raised. After the Ya'an earthquake, one foundation has received a total of 65 bitcoin donations, with a market price of about 50000 yuan
of course, money laundering, fraud, gambling and so on will follow. This case is a typical case of fraud under the banner of bitcoin trading. As the first case of bitcoin fraud in China, the public security organs have also concted in-depth study and understanding of the professional knowledge related to bitcoin, and finally cracked the case. On December 5, 2013, the people's Bank of China, the Ministry of instry and information technology and other five ministries and commissions issued the notice on prevention of bitcoin risk, which first made it clear that bitcoin does not have the status of legal tender, and required financial institutions and Payment institutions not to price procts or services with bitcoin. The central bank believes that there are three risks in bitcoin Trading: high speculative risk; High risk of money laundering and being used by criminals or organizations. In the future, the future of bitcoin is not clear, especially in sovereign countries, which will take a prudent and conservative attitude towards currency, which involves financial order and national security. Therefore, the public should also raise enough risk awareness.

The bitcoin white paper was first published at the end of 2008, when the creators sent it to multiple recipients on an encrypted mailing list. Strangely, its creator pretended to be Satoshi Nakamoto, hiding behind the pseudonym

Another reason for Nakamoto's anonymity can be explained as that the creators of alternative currencies easily put themselves at risk

In 1998, Hawaiian resident Bernard von nohaus created a private currency called free dollar. It has been popular for some time, but its coinage was suddenly raided by the FBI and secret service in 2007. After a criminal lawsuit in 2009, the money was confiscated and Bernard von norhaus was convicted of "making private coins that compete with the official currency of the United States."

In addition, in 2007, a digital currency called e-gold was accused of being illegal because it did not collect enough customer information. Its owner was sentenced to house arrest and the company was shut down. The arrest of entrepreneurs in alternative currencies by government agencies may have been a factor in China's decision to remain anonymous

everyone can use bitcoin. This means it can be used to pay for legal and illegal services, as well as legal bids however, it has always been a popular payment method in the black net market. Ross Ulbricht, the notorious dark Internet market maker and operator, was jailed for facilitating the trading of drugs and other contraband

Ross Ulbricht appealed to the US Supreme Court in December 2017, but is still in prison. If Nakamoto reveals his true identity, it can be inferred that he may face a similar fate

who would he be

in 2016, Craig Wright, an Australian programmer, claimed to be Chinese. He provided some evidence, but later found that it was not conclusive because it could be obtained publicly from books. He was also accused of falsifying announcements and blog posts to show his real Chinese version. For example, vitalik buterin, founder of Ethereum, recently called Craig white a liar

The other is Hal Finney. He is a famous cryptopunk and Cryptologist. He was also the first person to receive bitcoin from Nakamoto in 2009. He was also the first to download a bitcoin client. Before his death in 2014, however, Hal fini refuted the claim that he was Chinese

Some people think that Nick Saab, a famous Cryptologist, may be Nakamoto. Before the launch of bitcoin, he designed the architecture of distributed digital currency, which he called bitcoin. Although the architecture has never been moved, it is similar to the design of bitcoin. This led to widespread speculation. But he repeatedly denied it

although the real identity of Nakamoto may never be disclosed, it is important that the operation of the technology will not be affected
