What are the digital currencies with payment system
for example, bitcoin is called "digital currency" or "cryptocurrency". It's hard to say that it's money, because it doesn't have the characteristics of money
currency speculation or currency circle refers to the so-called currency. Future money, fire money... All belong to the same category. They are digital symbols with no real value and no security. Don't touch them if you don't understand them
in my opinion, these so-called digital coins are the modern version of Dutch tulips, which will return to zero sooner or later and become air coins.
virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency
in 2013, the central bank, together with five ministries and commissions, issued the notice on preventing the risk of bitcoin, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, not in the form of currency and legal currency< At the same time, digital currency is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes.
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. Currency digitization and digital currency are not the same thing, so don't confuse them
2. There may be legal digital currency in China in the future, but it must be issued by the Central Bank of China
3. Bitcoin is not a currency. Currency is a credit symbol issued by the Central Bank of a sovereign country. Bitcoin is a speculative target, which is not recognized by major countries in the world.
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
