What is virtual currency node
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>
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
reference: network virtual currency
a node is a network node in the blockchain distributed ledger system. By connecting servers, computers and other devices through the network, different types of blockchains have different ways to become nodes. For example, bitcoin participates in trading and mining, and EOS participates in election campaign to become a node
the following is what is a bitcoin full node
bitcoin full node is the node that downloads and preserves complete blockchain data by loading bitcoin clients (including bitcoin unlimited and bitcoin)
because of the congestion of the blockchain transaction network, the author solves the problem by adjusting the broadcast communication, information encryption and decryption, consensus mechanism and transaction verification mechanism. In the whole bitcoin network, from miners to ordinary users can be regarded as a node in the bitcoin network, but because bitcoin has the characteristics of multi centralization, In the whole network, its important role is "bitcoin all nodes."
bitcoin nodes constitute the bitcoin network and become a member of the network. To be able to trade with other nodes is to verify the transactions on the network (consensus mechanism).
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 difference between digital currency, electronic currency and virtual currency
in fact, digital currency is a kind of indexed RMB, a legal encrypted digital currency and an alternative currency in the form of electronic currency. Digital currency can be divided into two types: non cryptocurrency (e-gold, XRP) and cryptocurrency (bitcoin)
it can not be completely equivalent to the virtual currency in the virtual world, because it is often used for real goods and services transactions, not limited to online games and other virtual spaces. It is different from Alipay and WeChat, and Alipay, WeChat payment and mobile phone banks are all electronic money, not digital money. The popular digital currencies in 2016 include bitcoin, lightcoin, bitstock, etc. At present, there are thousands of digital currencies issued all over the world
virtual currency refers to the non real currency, especially the currency in the network virtual economy. The issuer is not the central bank, and it can only circulate in a specific virtual environment. In the case of the connection between virtual and reality, virtual currency has its real value. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point, roll counting of Shanda company, u-coin meter ticket launched by Sina (used for igome game), chivalrous Yuanbao (used for chivalrous road game), and grain silver (used for bixue Qingtian game). Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency. For example, bitcoin is illegal digital currency
since the beginning of the year, the relevant person in charge of the people's Bank of China has said that the future of mobile payment is bright, and the central bank is actively studying the relevant research results and practical experience at home and abroad to strive for the early issuance of digital currency. At the digital currency seminar of the people's Bank of China held on January 20, the relevant person in charge of the people's Bank of China disclosed that the central bank has set up a special research team since 2014 to conct in-depth research on the digital currency issuance and business operation framework, key technologies, circulation environment, etc., and strive to launch the digital currency issued by the central bank as soon as possible. At present, the research has achieved phased results
what benefits will digital currency bring to our lives
for this problem, the relevant person in charge of the central bank said that if the digital currency is successfully issued, it will bring many conveniences: it can effectively rece the high cost of the issuance and circulation of traditional paper money, and improve the convenience and transparency of economic transaction activities; It can rece money laundering, tax evasion and other illegal and criminal acts, enhance the central bank's control over money supply and money circulation, better support economic and social development, and help the comprehensive realization of Inclusive Finance; It helps to build a new financial infrastructure, further improve the payment system, improve the efficiency of payment and clearing, and promote the upgrading of economic quality and efficiency. More digital currencies can focus on bitMom

Digital money (electronic money or electronic currency) is a kind of money in digital form (different from paper money and coins). It shows properties similar to physical currency, but allows immediate transaction and boundaryless ownership transfer. Examples include virtual currency, cryptocurrency and currency issued by central bank and recorded in computer database (including digital base currency). Like traditional currencies, they may be used to buy physical goods and services, but they may also be restricted in some communities, such as online games
