Virtual currency yfi

2. Litecoin

litecoin (LTC), released on October 7, 2011, is the most valuable counterfeit coin at present, accounting for about 2% of BTC's market value. The current unit price is US $2.31, with a total currency value of US $38 million

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.

3. Virtual currency refers to the currency that does not exist in reality and exists in a virtual state, such as bitcoin, lightcoin, Ethereum and so on; Token refers to the form of money that can be used as a monetary function and can be used to purchase goods
virtual currency can be used for shopping transactions in certain situations, such as in some places abroad; At this time, it counts as a token and plays the role of currency
but token, such as the shopping card voucher printed by the company itself, can be used for the internal consumption of the company. To some extent, it is equivalent to token; However, it is not a virtual currency
that is to say, virtual currency may be token; But token is not necessarily a virtual currency.

4. Network virtual currency can be roughly divided into two categories: the first is familiar with the game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and uses these virtual game data to buy Herbs and equipment, or in some special games as a scoring unit to increase the fun of the game, which is an embodiment of the player level. But it can only be used in your own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services.

5.

Yfi is the token of year.finance. Year.finance is an aggregator for mobile mining (hereinafter referred to as "yfi" for ease of reading). There are compound, AAVE, lend, curve and other ore pools in the market. Due to information asymmetry and other factors, there is a huge difference in the rate of return between these ore pools. Users can automatically access high-yield ore pools through yfi platform to maximize mining income

on July 17, 2020, yfi announced on twitter that its official website was officially launched to start liquidity mining. Yfi launched four ore pools in the first batch, and users can participate in mining by providing affordability in balaner, with the highest annual income of more than 700%. Due to the super high yield, yfi has attracted a large number of users to participate. In just a few days, the amount of locked positions exceeded 100 million US dollars

extended information:

yfi issued 30000 pieces in total, the team had no reservation, no private placement, no public offering, and all of them were proced by mining. In other words, yfi issued only a limited amount, and all yfi participants were in the same line. It is a completely decentralized cryptocurrency, which is very similar to bitcoin. Therefore, as soon as yfi went online, it encountered crazy speculation

on July 17, 2020, yfi liquidity mining price is only 3 US dollars; The next day, yfi soared to $400

on August 20, 2020, the price of yfi exceeded US $13000 for the first time, surpassing bitcoin and becoming the new "king of money"

6. Connecting with the wallet on the first floor is equivalent to calling LTC to him. It's really bad. It's a cheat for novices
please accept if you are satisfied

7. Lafite is not a virtual currency, it's red wine. Bitcoin, Ruitai coin and Qianjin card are the virtual currencies of the market
Lafite is one of the most famous Bordeaux wines in the world. It was originally the abbreviation of Chateau Lafite Rothschild, the world's top winery. People used to call Lafite dry red wine (also known as big Lafite, Lafite dry red wine, Lafite genuine) and Lafite treasure dry red wine (also known as small Lafite, Lafite sub brand, carruades de Lafite) also referred to as Lafite. At the same time, Lafite also represents DBR (domains barons de Rothschild (Lafite)) of Lafite Rothschild Baron group, the owner of the winery. In a strict sense, only the large and small Lafite brewed by Lafite castle is the real Lafite wine, while the wines of other wineries of Lafite Rothschild group only belong to other wine brands of Lafite Rothschild group, and these wines only belong to the series of red wines proced by Lafite group, not Lafite wine.
