3. Bitcoin, of course, is the hottest one. In addition to bitcoin, there are also:
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

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

5. Digital currency is not very standard now, so we should be cautious.

6. Digital 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. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with 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 in electronic form
China: actively and steadily promote the implementation of the research on the central bank's digital currency
as early as 2014, the central bank set up a special research group on the issue of legal digital currency to demonstrate the feasibility of the central bank's issue of legal digital currency< On October 28, 2019, Huang Qifan, vice president of China Center for international economic exchange, said: "the people's Bank of China has studied DC / EP for five or six years, and I think it has become mature. The people's Bank of China is likely to be the first central bank in the world to launch a digital currency. "
on November 28, fan Yifei, vice governor of the people's Bank of China, said at the forum that at present, the central bank's legal digital currency DC / EP has basically completed the top-level design, standard formulation, function research and development, joint debugging and testing under the premise of adhering to double-layer delivery, M0 substitution and controllable anonymity. In the next step, we will follow the principle of steady, safe and controllable, reasonably select the pilot verification area, scene and service scope, continuously optimize and enrich the DC / EP functions, and steadily promote the introction and application of digital legal tender< European Central Bank: exploring the form and possibility of CBDC. 'we are analyzing what form CBDC may take in order to achieve its potential purpose and mitigate its potential negative impact on monetary stability and financial intermediation,' Mr. kindos said. On the stable coin, Mr jindos said that it was very uncertain whether the stable coin could deliver on its promise, and it was clear that it could bring risks to consumers and the financial system. So it is understandable that authorities around the world are calling for regulatory stability.

7. On January 20, 2016, the people's Bank of China announced on its website that it held a seminar on digital currency. At the meeting, the central bank asked its digital currency research team to "strive for the early launch of the digital currency issued by the central bank". Similarly, central banks such as the Bank of England and the Bank of Canada are planning or considering issuing their own digital currencies. After the advent of bitcoin triggered a wave of private issue and de nationalization of digital currency, the digital currency issued by the central bank seems to have become a global trend

digital currency is a new technology, which is different from the traditional electronic payment tools used by online banking and third-party payment companies. It is developed on the basis of a series of new technologies - they are not tools to transmit money; They are money in themselves. Among them, digital currency based on cryptography is also called cryptocurrency. Bitcoin is a model of this kind of digital currency. After its birth, it inspired many similar systems. Some commercial banks and central banks have also begun to develop their own digital currency. According to the different issuers, we can divide digital currency into three types:
1. Digital currency issued by non-financial institutions

in November 2008, a man named Nakamoto Tsung invented a new technology called blockchain and designed a point-to-point e-cash system, namely bitcoin, for the first time. On January 3, 2009, Nakamoto completed the code development of bitcoin. Due to its point-to-point and electronic nature, bitcoin can be passed directly between two people without the need for a centralized settlement institution. Therefore, it is a fast, low-cost, borderless payment system
2. Digital currency issued by commercial banks

some large international financial institutions have taken a fancy to the low-cost, fast and safe characteristics of digital currency, and began to try to use its underlying technology, namely blockchain technology, to develop their own digital currency. For example, four of the world's largest banks, UBS, Deutsche Bank, Santander bank and New York Mellon bank, are already involved. Their digital currencies are similar to those mentioned above, but their issuers are different. It is particularly noteworthy that financial institutions develop digital currency to meet the needs of their own rapid clearing transactions, rather than challenge the financial situation by replacing the legal currency issued by the central bank. The domestic Puyin group also launched Puyin
3. Digital currency issued by the central bank

some central banks, such as the people's Bank of China and the Bank of England, also plan to launch their own central bank digital currency after some research on digital currency. Technically, CBDC is the same as the above two, but e to its special identity, CBDC will have a greater economic impact, which is the reason why the central bank wants to introce CBDC.
