Quasi digital currency
digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions)
digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes
based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds
Electronic money and virtual money are called digital money. According to the definition of the European Central Bank, virtual money is issued by non central banks, credit institutions and e-money institutions, which can be used as the numerical expression of the value of currency substitutes in some cases{rrrrrrr}
extended information:
the process of digital currency trading through the platform is as follows:
(1) investors should register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time
(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures

(4) e to the difference between the buy and sell volumes submitted by users, a buy or sell request may be partially executed
bitcoin does not rely on specific currency institutions to issue. It is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
bitcoin is very similar to cash
the advantages of bitcoin are: no freezing, no tracking, no taxes, and extremely low transaction costs. Compared with people who speculate in currency, it is wealth, and people outside the currency circle may think it is a fraud
bitcoin, Ethereum, bitcash, EOS, REBO, etc. are the mainstream digital currencies, which can be properly invested. All transactions have risks. You can invest cautiously. You can search online for fire coin, coin security, OK, dobby trading platforms, etc. all of which can trade bitcoin. These are relatively large trading platforms, investing in mainstream digital currencies, and Don't invest in counterfeit money or air money.
in February 2017, the central bank made new progress in issuing digital currency. The block chain based digital bill trading platform promoted by the central bank has been tested successfully. The legal digital currency issued by the central bank has been put into trial operation on the platform. After the Spring Festival, the digital currency Research Institute of the central bank will also be officially listed. This means that the people's Bank of China will be the first central bank to issue digital currency and carry out real application in the world.
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.
Generally, the excellent digital currencies are mostly imported procts, such as bitcoin, Leyte coin, ether coin and so on. However, the domestic Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects of European crowdfunding are excellent digital currencies
digital currency (English: digital currency) is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank
it is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography
1. Bitcoin
the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
2. Litecoin (LTC) is an improved version of digital currency inspired by bitcoin. It was designed and implemented by a programmer who worked in Google. It was released on November 9, 2011. Lightcoin and bitcoin have the same implementation principle in technology, but the creation and transfer of lightcoin is based on an open source encryption protocol, which is not managed by any central organization
extended data
characteristics of bitcoin currency:
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
