Production plan of virtual currency
On June 28, 2009, the Ministry of culture and the Ministry of Commerce jointly issued the "notice on strengthening the management of virtual currency in online games", which made it clear that virtual currency is expressed in the form of prepaid recharge card, prepaid amount or points of online games, but does not include game props obtained in game activities; Virtual currency shall not be used to pay for, purchase physical procts or exchange for any procts and services of other enterprises< The following is the full text of the Circular of the Ministry of culture and the Ministry of Commerce:
the Circular of the Ministry of culture and the Ministry of Commerce on strengthening the management of virtual currency in online games
the cultural departments (bureaus) and commercial departments (bureaus) of all provinces, autonomous regions and municipalities directly under the central government, the Cultural Bureau and commercial bureau of Xinjiang proction and Construction Corps, Beijing, Tianjin, Shanghai and Chongqing Ningxia Hui Autonomous Region Cultural market administrative law enforcement corps:
with the rapid development of online games, online game virtual currency is widely used in online game business services. The virtual currency of online games not only promotes the development of online game instry, but also brings new economic and social problems. Mainly reflected in: first, the lack of protection of user rights and interests; Second, market behavior lacks supervision; Third, the online game virtual currency in the use of disputes
in order to standardize the operation order of online game market, according to the spirit of Interim Provisions on Internet culture management, notice on Further Strengthening the management of Internet cafes and online games (Wen Shi Fa [2007] No. 10) and notice on standardizing the operation order of online games and banning the use of online game gambling (Gong Tong Zi [2007] No. 3), etc, With the consent of the people's Bank of China and other departments, the notice on strengthening the management of virtual currency of online games is as follows
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
extended data:
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>
impact system
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

Background: the financial application of blockchain technology brings high investment value
2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles
1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:
in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost
2. Why can blockchain solve the above pain points:
blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs
3. The application of blockchain technology in the financial field mainly includes the following aspects:
① digital currency
among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits
Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost③ digital bills
④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost
The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points
in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it
Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall) In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreementbitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain
based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network
2. Master node network
the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

diamond and rust jonbaya
My God! Your phantom appears again
but it's not unusual
just because of the full moon tonight, you happen to call
I'm sitting here on my mobile phone
listening to my familiar voice, it was a few light years ago
as if falling down continuously
vaguely remember that your eyes are bluer than robin's eggs (note)
you said that my poem is terrible
& quot; Where are you calling from& quot;< br />" At a phone booth in the Midwest
ten years ago, I bought cuff links for you, and you also gave me some things.
we all know what memories can bring us.
they give us diamonds and rust.
when you suddenly appear in front of me, you are already a legend.
a phenomenon that can't be guarded against.
a real tramp, you drift into my arms,
and your stay, Like a short voyage on the sea
with the blessing of the virgin
to protect you from being hurt
now, I see you standing in the yellow leaves
your hair covered with snow
you smile,
in front of the window of the hotel overlooking Washington Square
you and I exhale like white clouds
condensing in the cold air
for me
we almost died at that time
now you say to me, You are not nostalgic
so please find another word to replace
you have always been good at playing with words
to make it ambiguous and difficult to understand
because now I just need such ambiguity
everything in the past is too clear
Yes, I love you deeply
if you give me diamonds and rust again
I will tell you that I have paid a price, When they come into contact with old Western songs, there are several pieces that they can't do. On the one hand, they can practice their playing skills. On the other hand, they have beautiful melodies that last for a long time< After Joan Baez, an American folk song, there are several such works handed down from generation to generation, such as "Donna, Donna", "the night they drop Old Dixie Down" and "diamonds and rust". Among them, "diamonds and rust" is a more difficult piece
Joan Baya has a clear, pure voice and mature skills. Many famous composers are willing to provide her with works to sing, so most of her well-known songs are not written by herself. "Diamonds and trust." is the most well-known one of her own songs
the lyrics of this song are lengthy and the images are complex, so many people can't understand the meaning even after looking up the new words in English. The reason is that the lyrics are about a personal relationship with Joan Baya< In the 1960s, she met Bob Dylan, later known as "the father of folk rock" and the most famous work was "blowing in the wind". They both cherished each other and appreciated each other's talents, so they had a secret love affair
the relationship ended in nothing. In 1975, Joan Baya wrote this song, which is based on the feelings of her teacher and friend. Later, "diamond and rust" is also considered to be her best composition
in English, "diamond" is often compared to "good things in memory". There is a song called "some days are diamonds, some days are stones." its metaphor is similar, while "rust" and "stone" are used to refer to "bad things in memory".
virtual currency is not a currency in China. In the bitcoin risk notice issued by the central bank and other five ministries and commissions on December 5, 2013, bitcoin is clearly defined as a special Internet commodity, which denies its monetary attribute and can not be used for payment, but people can buy and sell freely at their own risk. But people in the coin circle don't think so. Here is the view of the coin circle (take bitcoin as an example):
bitcoin has value because it is useful as a form of currency. Bitcoin has the mathematical characteristics of money (persistence, portability, interchangeability, scarcity, separability and identifiability) rather than relying on physical characteristics (such as gold and silver) or the trust of central authorities (such as fiat money). In short, bitcoin is backed by mathematics. With these characteristics, a form of money to have value requires trust and use. In contrast, this can be reflected in its growing base of users, businesses and start-ups. Like all currencies, the value of bitcoin comes directly from people who are willing to accept it as a means of payment, which is the only source
some people with insight of digital currency in China are also beginning to explore application scenarios other than digital currency payment. Digital currency scholar Mr. Sha Qian mentioned the concept of currency business circle and planned many application scenarios of bitcoin. Perhaps inspired by the coin business circle, the jewelry instry has developed an applied digital currency, Fuyuan coin, which is similar to the traditional business integral.
