Benefits of virtual currency node
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).
The role of digital currency:
1. First of all, the central bank's digital currency can provide a huge data base for monetary policy and macro Prudential policy, so that the regulatory authorities can collect real-time trading books of different frequency and different institutions according to their needs, and it is complete and real. This information advantage can help the central bank use policy tools more accurately and flexibly
Secondly, the central bank's digital currency technology can track the flow of funds and help the regulatory authorities to comprehensively monitor and assess financial risks. Finally, the central bank's digital money technology is concive to the transmission of interest rate of monetary policy. Digital currency technology supports "point-to-point" payment and settlement, which can improve the liquidity of market participants. Only the digital currency of the central bank, which is generally accepted by the whole society, can radiate this advantage to the participants of different financial markets, so as to improve the liquidity of financial markets. This will make the term structure of interest rate smoother and the transmission mechanism of interest rate smoother 
extended data:
digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: because it comes from some open algorithms, digital currency has no issuing subject, so no one or institution can control its issuing; Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation.
the value of virtual currency is that it is based on blockchain technology, has high security, and is suitable for being a decentralized currency after a period of depression, the price of bitcoin has recovered again recently, standing at the price of US $40000, which is the biggest rebound in the price of bitcoin since this month. In fact, since last year, the bitcoin market has ushered in a wave of rising prices. Some analysts say that the main driving force for the rise is that large financial institutions begin to enter the market and take bitcoin as a part of their asset allocation. Some well-known investment companies and fund companies, and even conservative insurance companies regard bitcoin as one of the investment options
after the release of the report "bitcoin soaring or hidden" exchange factor "vigilance policy raid and market risk" on January 5, the fermentation of a series of events such as the central bank's interview with bitcoin platform and the platform's self rectification not only fulfilled our previous prediction, but also showed that the further attention of the regulatory authorities is promoting bitcoin into a relatively strong regulatory cycle
however, considering that bitcoin is a decentralized currency based on international blockchain technology, and its stability has a gold like rigid guarantee, although regulatory policies will have a negative impact on the ecology of bitcoin in the short term, the development of bitcoin in the medium and long term is still worth looking forward to at a time when inflation expectations become more obvious
domestic applied digital currency is also very popular, such as Puyin, which issues 1 billion Tibetan tea as credit endorsement. The identification, evaluation, right confirmation and other related information of Tibetan tea assets will be recorded on the blockchain through encryption technology, so that the asset related information will be more open and transparent.
