this is also a distributed (decentralized) digital currency. Unlike the sha256 mining algorithm used by bitcoin, LTC adopts scrypt algorithm. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory. Each hash is used as the seed of the input, and then it needs a lot of memory to store another pseudo-random sequence to generate the pseudo-random points of the sequence and output the hash value. In the mining of BTC (bitcoin), it is not enough to rely on simple graphics card mining (it takes about ten to dozens of days to dig a BTC with general configuration graphics card). The emergence of various expensive mining machines has raised the threshold for ordinary people to get BTC through mining, while LTC has certain advantages in using PC graphics card mining This passage comes from Zhihu.)
compared with BTC, litecain has made a little improvement in technology. If BTC is gold now, LTC is silver for the time being
the biggest advantage of litecoin is that it can confirm the authenticity faster. The virtual currency is designed and maintained by Charles Lee. Bitcoin transactions need to be verified, and the average verification time is more than 10 minutes. Most transaction websites need 1 hour to verify. The average transaction confirmation time of liteoin is 2.5 minutes. Developers claim that shortening the verification time increases the practicability of virtual currency. The bitcoin mining efficiency of customized machine and AMD GPU is the highest, making it almost unprofitable for miners using CPU mining. Litecain's mining excludes GPUs and custom processors, so it doesn't rely too much on a small number of professional miners
ppcoin
ppcoin (PPC) was released on August 19, 2012, which has improved the original technology of BTC. Use proof of make and add the concept of coin age
ppcoin is a bifurcated project of bitcoin, which aims to achieve energy efficiency and maintain the best performance of the original bitcoin as far as possible. The unit price of ppcoin is US $0.22 and the total currency value is US $4 million
ppcoin does not have a fixed upper limit of money supply, but it does not mean that ppcoin has obvious inflation compared with bitcoin. Bitcoin can be compared to gold. The annual inflation rate of gold is about 1-3%. Although gold has no known upper limit of money supply, we still know that it is a reliable scarce commodity
ppcoin has two types of casting: work certificate and equity certificate. The coinage rate of working proof is affected by Moore's law, which depends on the doubling of our working proof ability. What we all know is that Moore's law will eventually come to an end. By then, the ppcoin of inflation may be close to the gold level. The annual maximum inflation rate of certificate of equity is 1%. At the same time, ppcoin's transaction costs were destroyed to fight inflation. So on the whole, the coin design of ppcoin is still a very low inflation design in the future, which can be comparable with bitcoin<
ppcoin's reward is similar to lottery, which will determine the winning probability according to the number of ppcoin held by miners. Sunny king, one of the founders, said that their design is based on a new concept of long-term energy efficiency
terracoin
terracoin (TRC) was released on October 26, 2012, with a total currency of 42 million. The speed of each block is 2 minutes, slightly faster than LTC. There is not much special in technology, similar to the proction of BTC halved every four years
however, the operation team seems to have a strong business background and may be better than other bitcoins in circulation. The development of virtual currency is getting more and more attention. Now some teams with business background will accelerate the development of virtual currency
namecoin
namecoin is a distributed domain name system based on bitcoin technology. Its principle is the same as bitcoin. The first release date of this open source software is April 18, 2011
namecoin is generated from an original block which is different from bitcoin's main trading block. It uses a new blockchain, which is independent of bitcoin's blockchain. Because it is based on bitcoin, the security, distribution, robustness, encryption and migration of domain names are guaranteed mathematically. You can dig bitcoin and namecoin at the same time
this project was discussed and proposed by bitdns, which is mainly dissatisfied with the defects of DNS. The only top-level domain name of namecoin is. Bit. It costs namecoin to register a. Bit domain name
in addition, Q currency, Shanda currency, starting point currency and various online game currencies are also virtual currencies.
The concept of bitcoin was founded by Nakamoto
On December 12, 2010, when bitcoin graally became a hot topic, he quietly left and disappeared from the Internet As a descendant of samurai, Nakamoto was born in 1949 in Beppu, Japan. His mother, quanzi, was a Buddhist and brought him up in poverty When his parents divorced in 1959, Nakamoto's mother remarried and immigrated to California with her three sons. Nakamoto and his stepfather don't get along well, but according to his younger brother Arthur, Nakamoto showed his talent in mathematics and science when he was very young, but also showed his "fickle and strange interest"Nakamoto graated from Caltech, majoring in physics. Upon graation, he joined Hughes Aircraft and worked in defense and electronic communications. Later, Nakamoto worked for the U.S. military, and his experience was classified as a state secret. Now searching his files, his life is a blank
In 2008, in an e-mail group discussing information encryption on the Internet, he published an article outlining the basic framework of the bitcoin system. In 2009, he established an open source project for the system, officially announcing the birth of bitcoin. On December 12, 2010, when bitcoin graally became the climate, he quietly left and disappeared from the InternetThere are four stages of currency experience:
1, accidental barter
accidental barter refers to the human's initial commodity exchange at the end of the primitive society. It occurs under the extremely accidental situation that both sides of the tribe have surplus procts. At this time, commodity exchange has great contingency, so it is called accidental barter
With the development of proctivity and social division of labor, the frequency of barter has increased, and the types of commodities participating in the exchange have also increased. At this time, commodity exchange is the expanded barter When the scope of the transaction is expanded and the variety is increased, the exchange of things is very difficult. Even if it can be established, it will cost too much manpower, material resources and time. The low exchange efficiency has seriously hindered the development of commodity proction Therefore, the general equivalent is a special commodity separated from the commodity world as a unified expression of the value of all other commodities. This is the proct of the development of commodity proction and exchange to a certain stage The general equivalent is fixed on gold and silver.
the commodity used as the general equivalent is different in different regions and periods, which is not concive to the development of commodity economy objectively. Because gold and silver are rare and easy to be separated and stored, they are graally fixed as general equivalents, and money comes into being
extended data:
money is a fixed commodity separated from commodities and serves as a general equivalent
In essence, money is a contract between the owner and the market about the right of exchange, which is essentially an agreement between the owners. I give what I have to the market in exchange for what I need. Money is the agreement in this process, which reflects the economic cooperation between indivials and societythe nature of money contract determines that money can have different forms, such as general equivalent, precious metal money, paper money, electronic money and so on. It can be used as a medium of transaction, storage value, deferred payment standard and accounting unit
According to issuers, money can be divided into public money (fiat money), private money and regional money (community money). Generally speaking, public money is issued by the government. When it exists, it is generally dominant. Private money and regional currency are issued by non-governmental organizations According to the classification of materials, people used different goods as money in different historical periods. It can be divided into shell, bead, stick, metal currency (see commodity currency), paper currency and digital currency. In terms of nature, it can be divided into real money and virtual moneyreference: network currency
When the global financial crisis broke out in 2008, someone published a paper under the pseudonym of "Nakamoto Tsung", describing the mode of bitcoin
many bitcoin players are attracted by the fact that bitcoin can not be issued at will. Contrary to the attitude of bitcoin players, economists have a polarized attitude towards the fixed amount of 21 million bitcoin
Economists of Keynesian school believe that the government should actively regulate the total amount of money, and use the tightness of monetary policy to timely fuel or brake the economy. As a result, they believe that bitcoin's fixed aggregate currency sacrifices its adjustability, and worse still, it will inevitably lead to deflation, thereby harming the overall economy. Austrian economists hold the opposite view. They think that the less the government intervenes in money, the better. The deflation caused by the fixed amount of money is not a big deal, even a sign of social progressbitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer
when bitcoin was born in 2009, each reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the bounty will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5
first of all, according to its design principle, the total amount of bitcoin will continue to grow until it reaches 21 million more than 100 years later. But the total amount of bitcoin will grow very slowly in the later period. In fact, 87.5% of bitcoin will be "g up" in the first 12 years. Therefore, in terms of the total amount of money, bitcoin will not reach a fixed amount, and its total amount of money will continue to expand, although the speed is getting slower and slower. So it looks like bitcoin is the inflation currency
However, the judgment of deflation or inflation is not based on whether the total amount of money is decreasing or increasing, but on whether the overall price level is falling or rising. The rise of overall price is inflation, and vice versa. In the long run, the issuing mechanism of bitcoin determines that the growth rate of its total amount of money will be far lower than that of social wealth Economists of Keynesian school believe that the continuous decline of prices will make people tend to postpone consumption, because the same dollar can buy more things tomorrow. The rection of consumption will further lead to shrinking demand, unsalable goods, lower prices and a vicious circle of "deflation spiral". Similarly, the deflationary currency itself can appreciate even if it is not deposited in the bank (the purchasing power becomes stronger and stronger), people's willingness to invest will increase, and social proction will fall into a downturn[ 5] Therefore, bitcoin is a currency with deflationary tendency. In bitcoin economies, commodity prices priced with bitcoin will continue to fallbitcoin is a kind of network virtual currency with limited quantity, but it can be used to cash out: it can be converted into the currency of most countries. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items

bitcoin is a new type of virtual currency, which is generated by a large number of calculations based on special algorithms. According to rigorous calculations, the stock of bitcoin is limited, with a total of 21 million, no more or less. After being created, bitcoin has rapidly become a "fixed asset" pursued by Internet speculators
in February 2014, mtgox, the world's largest trading platform, went bankrupt, casting a shadow on the whole bitcoin instry. Since the middle of 2014, the price of bitcoin has been in a downward trend for a long time

on the afternoon of February 8, 017, the inspection team of the business management department of the people's Bank of China interviewed the main principals of nine bitcoin trading platforms in Beijing, including "China bitcoin", "bitcoin trading network", "bitcoin", "yuncoin", "Yuanbao", "btc100", "jucoin", "coin shell" and "dahonghuo", which are engaged in bitcoin trading, Report the current problems of bitcoin trading platform, prompt the possible legal risk, policy risk and technical risk of the trading platform, understand the operation of the nine trading platforms, and put forward clear requirements: it is not allowed to engage in financial business such as financing currency, participate in money laundering activities, and violate the relevant national anti money laundering and anti money laundering regulations Foreign exchange management, payment and settlement and other financial laws and regulations shall not violate the state tax and instrial and commercial advertising management laws and regulations. If any bitcoin trading platform is found to have violated the above requirements and the circumstances are serious, the inspection team will request the relevant departments to shut down and ban it according to law

first, the evolution from natural currency to artificial currency
in Chinese characters, most of the characters related to value have changed from "Bei". From this we can see that Bei is the earliest currency in China
with the rapid development of commodity exchange, the demand for money is increasing, and seashells have been unable to meet people's needs. People began to imitate seashells with copper. The appearance of copper shell is an important evolution from natural currency to artificial currency in ancient Chinese currency history
with the extensive use of artificial coinage, seashells, as a natural currency, graally withdrew from China's currency stage< From the appearance of Tongbei in the Shang Dynasty to the Warring States period, China's currency graally formed four systems characterized by the domination of the feudal lords, namely, shovel coin, Dao coin, ring coin and Chu coin (yuan Jin and Yi Bi Qian)< After Qin unified China, the first emperor of Qin promulgated the earliest currency law of China in 210 BC, which stipulated that the half Liang coins with round square holes of Qin state could be used throughout the country
the circulation of Qin banliang coins with round square holes in the whole country has ended the disordered state of different shapes and great weight differences of ancient Chinese coins, which is a significant evolution from disordered shape to standard shape in the history of ancient Chinese coins. The shape of this round square hole determined by the Qin banliang coins continued until the early Republic of China< Third, the evolution from local coinage to central coinage. The gentry, the rich businessmen and the local forces took advantage of the opportunity to make money. In the reign of Emperor Wen, "Dr. Deng Tong also made money for the king."< In the fourth year of Yuanding (1115 years ago), Emperor Wu of the Han Dynasty took back the minting right of the prefecture and minted five baht coins by the central government. From then on, it was determined that the central government should be responsible for the unified management of coin casting and issue, which was a significant evolution from local coin to central coin in the history of ancient Chinese currency
since then, the central government has been directly in charge of the coinage of all dynasties. The return of the minting right to the central government played an important role in stabilizing the political situation and economic development of the dynasties< (4) the evolution from the weight of documents to Tongbao and Yuanbao (24 baht is one or two)<
in the fourth year of Wude (621), Emperor Gaozu of Tang Dynasty, Li Yuan was determined to reform the currency system, abolish ancient coins of different weights, and cast "Kaiyuan Tongbao" coins with the idea of "opening up a new era". Kaiyuan Tongbao is a change from the weight of documents to Tongbao and Yuanbao in ancient China
Kaiyuan Tongbao coin is the earliest Tongbao coin in China. Since then, copper coins in China no longer use money to mark the weight, but use Tongbao and Yuanbao. It has been used until the "Tongbao of the Republic of China" after the 1911 Revolution< In the Northern Song Dynasty, e to the shortage of copper materials, the government made a lot of iron coins in some areas to make up for the shortage of copper coins. According to the records of the history of Song Dynasty, the cast iron coins in Sichuan at that time always weighed 25 Jin and 8 Liang. To buy a piece of silk in Sichuan, you have to pay 130 Jin of iron. Iron money is so cumbersome and inconvenient that paper money jiaozi came into being in Sichuan. The appearance of Jiaozi is an important evolution from metal currency to paper currency in ancient Chinese currency history
Jiaozi is not only the earliest paper currency in China, but also the earliest paper currency in the world< In the late Qing Dynasty, with the graal introction of foreign advanced science and technology, we began to buy coin making machines abroad ring the reign of Guangxu to make silver and copper coins. Later, Guangdong began to use machine-made holes when ten copper. Because of the huge profits of the manufacturers, many provinces followed suit
the emergence of mechanism currency in the late Qing Dynasty is an important evolution from manual coinage to mechanism currency in the history of ancient Chinese currency
since then, great changes have taken place not only in the process of casting currency, but also in the end of the life of the round square hole coin, which has been in circulation for more than 2000 years.
