Introduce the digital currency
digital currency is characterized by low transaction cost, fast transaction speed and high anonymity
1, low transaction cost
compared with traditional bank transfer, remittance and other ways, digital currency transaction does not need to pay fees to the third party, and its transaction cost is lower, especially compared with the cross-border payment that provides high handling charges to payment service providers
2. Fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization. It does not need any centralized organization similar to the clearing center to process data, and the transaction processing speed is faster
3. High anonymity
in addition to the point-to-point transaction without intermediary participation, one of the advantages of digital currency compared with other electronic payment methods is that it supports remote point-to-point payment, and it does not need any trusted third party as intermediary, Both sides of the transaction can complete the transaction in a completely unfamiliar situation without mutual trust, so they have higher anonymity, which can protect the privacy of traders. But at the same time, it also creates convenience for cyber crime, which is easy to be used by money laundering and other criminal activities

the impact of digital currency:
digital currency is a double-edged sword. On the one hand, the blockchain Technology it relies on realizes decentralization and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular
On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stabilityDigital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. More generally speaking, digital currency is actually a commodity
just like gold, it took more than 200 years to be graally recognized by the world. In the early days, many people questioned gold's ability to store value. If we take digital currency as a substitute, people's questioning attitude towards gold in the past is equivalent to many people's attitude towards digital currency now
extended data
digital currency is a balance between financial security and innovation ability. Financial instry should have clear access threshold. Digital currency involves finance, so it must have clear access threshold. The enterprise qualification of blockchain and digital currency needs to be reviewed and an access system set. One of the core of supervision is that blockchain enterprises must have qualified technical personnel
for example, enterprises of different levels in the construction instry need different levels and numbers of registered structural engineers to ensure the safety of buildings and bridges, which can also be used for reference in the supervision of digital currency. In addition, investors need to refer to the requirements of the "measures for the appropriateness of securities and futures investors" issued by the CSRC, and only those who meet certain conditions can participate in the investment
1. Litecoin is similar to bitcoin, which is also an encrypted digital currency, and its price has risen sharply recently. It is a P2P open source digital currency, which can be regarded as a branch of bitcoin. However, although lightcoin is based on bitcoin protocol, it does not require very high computing power. It can also be mined using ordinary computers. Lightcoin's algorithm comes from the algorithm designed by Dr Colin Percival for tarsnap secure online backup service (backup for Linux and other open source operating systems)
2. Namecoin
namecoin is also based on bitcoin, which is another branch of open source. Namecoin is a distributed DNS protocol -- generally speaking, it can transform the website name (such as ifeng. Com) that can be understood by human into the address that can be understood by machine. As its own DNS, this kind of currency can operate outside the normal Internet, so it can break away from the control of ICANN
the monetary value and domain name of namecoin are stored in the user's blockchain records, limiting the total number to 21 million
3. Peercoin
peercoin is a peer-to-peer variant of bitcoin, which can improve mining efficiency and security, and improve safeguard measures to avoid group mining. Now, group mining has been considered as a potential defect of bitcoin. According to the statistics of emerging currencies by coinmarketcap.com, peercoin currently ranks fourth in the market value of digital currencies
4. Primecoin
primecoin is a cryptocurrency similar to bitcoin, but it uses a completely independent mining algorithm. Bitcoin uses the hashcash algorithm, while prime coin uses the long Cunningham chains to create the value of money - a sequence of prime numbers named after mathematician AJC Cunningham
in the process of bitcoin mining, as the amount of money goes on, the difficulty will increase sharply. But prime is different. Every time a primecoin is mined, the mining difficulty will increase slightly, and the process is much more stable< 5. Feathercoin
based on the design of litecoin, released in April 2013, can adjust the mining difficulty more frequently than litecoin. Feathercoin will be updated frequently, adding new features and improvements to eliminate malicious mining behavior
6. Novacoin
another P2P digital cryptocurrency. Novacoin is different from most other currencies in that it integrates a protection mechanism in the currency core, which can identify illegal mining activities
the total number of novacoin is limited to 2 billion, which is considerable. If necessary, the total can be adjusted upward
7, infinitech
published in June 2013. A by-proct of litecain. According to the mining situation and the total amount of money, infinite money can frequently adjust the mining difficulty ratio< Megacoin was only released in the fourth quarter of 2013, imitating bitcoin in the early stage. The total number of megacoin is limited to 42 million, which can be mined like other virtual currencies. Its biggest selling point is brand publicity, which other digital currencies lack< It was released in 2013 and is still in its infancy. In the security part of quarkcoin, nine independent loops are deployed and six different algorithms are used.
digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by central banks or authorities, nor linked to legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded electronically
