network virtual currency can be roughly divided into
the first category is familiar 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 using these to buy Herbs and equipment, but it can only be used in his 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
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Wright currency (LTC), Fuyuan currency (FTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and it is also a new payment system. Fuyuan coin is an applied digital currency, similar to business points. Buy jewelry to get Fuyuan coin, which can be used to buy jewelry.
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.
in the form of game fraud, game account theft, etc
1. Q coin
Q coin, referred to as QB, also known as QQ coin, Tencent Q coin, etc. Usually its exchange rate is 1q currency = 1 RMB, with Tencent paipai net transactions are generally 10% off
QB is a virtual currency launched by Tencent, which can be used to pay for QQ bank number, QQ member service and other services. Tencent q-coin, through the purchase of QQ card, telephone recharge, bank card recharge, network recharge, mobile phone recharge card, one card recharge card and other ways to obtain
The face value of QQ card is 10 yuan, 15 yuan, 30 yuan, 60 yuan, 100 yuan and 200 yuan respectivelythere is another kind of electronic cryptocurrency, qqcoin, which is not related to each other
2. Litecoin
litecoin, abbreviated as LTC, currency symbol: Ł; It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world
lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization
3, infinite coin
infinite coin (hereinafter referred to as IFC) is a new digital currency, which has more circulation advantages than bitcoin, and fills the short board of bitcoin in the field of commercial circulation and promoting commercial operation. The positioning of unlimited money is to serve the daily life of small transaction payment
one transaction of infinite coin needs three confirmations, each confirmation takes three seconds, and the transaction confirmation speed is very fast. Because bitcoin transaction needs 6 confirmations, which takes about 1 hour, and lightcoin transaction takes 15 minutes, infinite coin is used in daily common transactions, which is more practical
infinite coin was released on June 5, 2013. Based on scrypt POW algorithm. A block is generated in 30 seconds. In the initial block, there are 524288 infinite coins in each block. After that, for every 86400 blocks generated, the number of coins in the block is halved, with a total of 90.6 billion. The difficulty of mining is adjusted every hour
Quark coin is not the currency in real life, it exists safely in the computer of global networkquark network is protected by six most advanced encryption algorithms to ensure that it can become a digital ledger. The whole network uses each of the six functions to generate a proof of work, and the coin maker must "verify" these transactions to ensure that each coin increase is real and effective
only regular computer can participate in ensuring that it can maintain a highly secure peer-to-peer network, which makes it more decentralized
quark coins can only be g up through the CPU of regular computers. In the first 36 weeks, a total of 247605120 quark coins will be g out. Since March 30, 2014, the annual quark coins set at 1050000 can enter the market through "digging", and the block reward will never be less than one, which is currently two
Zetacoin is an open-source digital currency based on SHA-256 algorithm. The initial coin mining is 160 million coins, and the subsequent annual inflation is a better incentive, To keep the hash of the network is not pure transaction cost The total number ofzetacoin is 160 million, 1000 zets per block and half of 80640 zets per block
network virtual currency can be roughly divided into
the first category is familiar 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 using these to buy Herbs and equipment, but it can only be used in his own game console.

the third kind of virtual currency on the Internet, such as bitcoin (BTC), Fuyuan coin (FTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency.
in the future, blockchain will be applied in any field and bring great impact on human life. Blockchain technology is regarded as one of the main protocols of the next generation of value Internet. Blockchain technology will be useful in any field of proction and life that lacks trust. From digital currency to securities and financial contracts, health care, games, artificial intelligence, intelligent contracts, Internet of things, identity authentication, asset trading, e-commerce, social communication, file storage and other fields can be widely used
in the aspect of medical treatment
when the blockchain technology is used to save the personal medical records, there will be the historical data of personal medical treatment, which can be understood as the electronic medical records on the blockchain. In the future, there will be data for medical treatment or health planning, and the real master of this data is the patient himself, not the hospital or a third-party organization. In addition, these data have strong privacy, and the use of blockchain technology also helps to protect the privacy of patients
payment system
compared with the existing traditional payment system, blockchain technology can avoid the complex system, directly between the two sides of the transaction, does not involve intermediary institutions, even if part of the network is paralyzed, it will not affect the operation of the whole system. This method has the characteristics of low price, fast speed, and no intermediate fees
banking
as a digital, secure and anti-interference account, blockchain realizes the core function of Banking: the safe storage and transfer center of value. Some banks with keen sense of smell in the world have begun to actively plan to join the army of blockchain research and application in order to gain the initiative in the fierce competition in the future
identity authentication of blockchain
blockchain has the feature of being accessible to everyone. Everyone can query the block information in any place with network. The high transparency also makes blockchain full of charm. In the future, ID card and account book are basically not needed, because every identity information can be written into the blockchain. When you need to verify the information, you only need to look it up to find it
election
based on the voting transaction on the blockchain, it can be confirmed that no vote has been modified or deleted, and there will be no improper voting
Real Estate
blockchain technology can change the operation mode of the real estate market. It can combine many complex processes and cases that real estate companies usually deal with, speed up the transaction process, rece fraud, and provide more transparent and secure transactions for each participant. Provides a way to achieve paperless and fast trading needs
securities issuance and trading
the probability of various kinds of errors in general stock and other securities trading is too high, which requires manual correction, thus prolonging the time required for transaction settlement. Through the transaction of distributed ledger, the automation of the whole process can be realized, and the security and efficiency can be improved. The identity and transaction volume of the trading party are recorded on the blockchain in real time, with an open, transparent and traceable system. It is concive to the market maintenance of securities issuers and regulatory authorities, and can rece the occurrence of black box operation and insider trading
in the scenario of relatively closed, multi-party trust problems and carrying value transmission, blockchain has unique technical advantages and also shows unique charm, which has great application imagination space. At the current stage, blockchain is worth exploring in some scenarios.
