The issue of virtual currency refers to
Zhou Xiaochuan pointed out that as legal tender, digital currency must be issued by the central bank. The issue, circulation and transaction of digital currency should follow the idea of integration of traditional currency and digital currency, and implement the same principle of management. That is to say, q-coin and the like are definitely not good
as for whether to use blockchain technology to create digital currency. Zhou Xiaochuan said that the blockchain technology is an optional technology, but so far, the blockchain still occupies too many resources. Whether it is computing resources or storage resources, it can't cope with the current transaction scale, and whether it can be solved in the future depends on it. Zhou Xiaochuan said that in addition to blockchain technology, the digital currency research team of the people's Bank of China has also concted in-depth research on other related technologies involved in digital currency, such as mobile payment, trusted and controllable cloud computing, cryptographic algorithm, security chip, etc
it is certain that the digital currency issued by the central bank can never be the same as bitcoin, Ruitai, Qianjin card and other digital currencies. The digital currency issued by the central bank is just the digital currency.
virtual currency is the currency used for electronic circulation. Now the scope of virtual currency is very large, including q-coin, bitcoin and so on. With the development of digital currency, virtual currency is becoming more and more abundant, which may become the mainstream in the future. For example, BTC, EOS, bcbot and so on are not only virtual currencies, but also algorithms, landing projects and technologies
virtual currency is mainly issued by online game service providers to purchase game props, such as equipment, clothing, etc. But at present, the use of virtual currency has gone far beyond this category. Virtual currency can be used to buy game cards, physical objects and download services of some movies and software

real risk
as the proct of e-commerce, virtual currency has begun to play an increasingly important role, and it is more and more connected with the real world. However, with the growth of virtual currency, the relevant laws and regulations are lagging behind, which has laid many hidden dangers
fraud
the private transaction of online virtual currency has realized the two-way circulation between virtual currency and RMB to a certain extent. The activity of these traders is to buy all kinds of virtual currencies and procts at a low price, and then sell them at a high price to earn profits. With the increase of such transactions, there are even virtual mints. In addition to the virtual currency provided by the main company, there are also some people who specialize in "virtual coin making" to obtain virtual currency by playing games and then resell it to other players
Taking Wenzhou as an example, there are about seven or eight such "virtual mints" with four or five hundred practitioners. This not only creates a bubble for the price of the virtual currency itself, but also causes trouble for the normal sale of the issuing company. It also provides a platform for selling and collecting money and money laundering for various cyber crimes. p>

in modern financial system, the issuers of money are generally central banks, which are responsible for the management and supervision of money operation. As the equivalent exchange goods used to replace the real currency circulation on the Internet, the virtual currency on the Internet is essentially the same as the real currency. The difference is that the issuers are no longer central banks, but Internet companies
if the development of virtual currency makes it form a unified market, each company can exchange with each other, or virtual currency is integrated and unified, and all of them are based on the same standard and price, then in a sense, virtual currency is currency, which is likely to form a threat impact on the traditional financial system or economic operation

anyone can run software on special hardware to become a bitcoin miner. Mining software monitors transaction broadcast through P2P network and performs appropriate tasks to process and confirm these transactions. Bitcoin miners can earn transaction fees paid by users to speed up transaction processing and additional bitcoin issued according to fixed formula
new transactions need to be included in a block with mathematical workload proof before they can be confirmed. This kind of proof is hard to generate because it can only be generated by trying billions of calculations per second. Miners need to run these calculations before their blocks are accepted and rewarded. As more people start mining, the difficulty of finding effective blocks will be automatically increased by the network to ensure that the average time to find a block remains at 10 minutes. Therefore, the competition for mining is very fierce, and no indivial miner can control the content contained in the block chain
workload proof is also designed to rely on previous blocks, which forces the time sequence of block chain. This design makes it extremely difficult to cancel previous transactions, because the workload proof of all subsequent blocks needs to be recalculated. When two blocks are found at the same time, the miner will process the first block received, and once the next block is found, it will be transferred to the longest block chain. This ensures that the mining process maintains a global consistency based on processing capacity
bitcoin miners can neither increase their rewards by cheating, nor deal with the fraulent transactions that destroy the bitcoin network, because all bitcoin nodes will reject the blocks containing invalid data that violate the bitcoin protocol rules. Therefore, even if not all bitcoin miners can be trusted, the bitcoin network is still secure.
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Fuyuan coin (FTC) and Wright currency (LTC). Bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency.
China does not have the first legal virtual currency. At the end of 2013, the central bank and other five ministries and commissions issued the bitcoin risk notice, which clearly defined bitcoin as a special Internet commodity, and the public can buy and sell it freely on the premise of taking their own risks
other digital confidential currencies are also suitable, such as Laite coin, the ancestor of Shanzhai coin, Fuyuan coin for business points in jewelry instry, dog coin for small reward, etc. But although virtual currency exists legally in our country, it is illegal to cheat under the guise of virtual currency

network problems
in addition to direct cash, virtual currency can also be purchased by SMS, internet transfer and fixed telephone recharge. These ways of purchase not only provide convenience for users, but also have many risks
such as embezzlement of telephone recharge and purchase by minors. In addition, virtual currency does not have the anti-counterfeiting technology of real currency. Computer hackers may use its security loopholes to proce counterfeit currency. Relevant personnel of the State Administration for Instry and Commerce said that virtual currency transaction is a business behavior derived from the Internet era, and there are no clear legal provisions to regulate it, and there are no items related to virtual goods transaction in the scope of instrial and commercial registration
but when the virtual property transaction graally employs people, places are fixed, transaction profits are clear, and has the nature of operation, it may involve market order and tax issues. Even game operators have no ability to control. There are a large number of "counterfeit banknote makers" in the network. Take the winger who is mainly engaged in chess and card online games as an example, the purchasing power of his online currency has shrunk by nearly 40% in one year. Many people point out that such inflation will only damage netizens and make them lose confidence in the Internet

network token: it is a kind of virtual currency equivalent to normal currency that can circulate on the network. Such as the common Q coin. This is mainly to facilitate users in a variety of consumer activities on the network. In the early stage, free quantitative distribution is used to guide consumers to a virtual consumption habit. In the later stage, special sales channels are set up.
where m is the maximum bending moment of the steel tube< br /> γ X is the plastic development coefficient of the section; For steel pipe section, it is taken as 1.15,
WNx - net section molus of steel pipe, also known as net section resistance moment. If the section is not weakened, it can be found in the section steel table in the steel structure design manual. If the section is weakened, it can be calculated according to the formula of material mechanics and the section size
the maximum normal stress of the steel pipe calculated by this formula should be less than the strength design value of the steel pipe (according to the different steel grades you choose, the strength design value of the steel pipe is also different, and this value can also be found in the steel structure design manual). To meet this requirement, the steel pipe meets the strength requirements under bending moment.
