Digital currency pizza Festival

1.

digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions)

digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes

based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds

Electronic money and virtual money are called digital money. According to the definition of the European Central Bank, virtual money is issued by non central banks, credit institutions and e-money institutions, which can be used as the numerical expression of the value of currency substitutes in some cases

extended information:

the process of digital currency trading through the platform is as follows:

(1) investors should register accounts first, and obtain digital currency accounts and US dollar or other foreign exchange accounts at the same time

(2) users can buy and sell digital currency with the money in their cash account, just like buying and selling stocks and futures

(3) the trading platform will sort the buying requests and selling requests according to the rules and start to match them. If they meet the requirements, the transaction will be concluded

(4) e to the difference between the buy and sell volumes submitted by users, a buy or sell request may be partially executed

2. What is a Leyte coin? To put it simply, litecoin (LTC)
was released on October 7, 2011. It is currently the highest market value counterfeit coin, about 1% of BTC's market value, or US $1000W. Compared with BTC, LTC is faster, with an average of 2.5 minutes and 6 confirmations per block in 15 minutes. In addition, the number of LTCs is four times that of BTCs, with a total of 8400w. At present, LTC uses scrypt algorithm, which needs a lot of memory support. The professional mining machine on the market can not be used for LTC mining, only the graphics card
what is the difference between lightcoin and bitcoin
1. Transaction: easier to use, larger volume and greater appreciation potential. The block confirmation time is shorter, which is four times faster than bitcoin. For example, pizza owners are more willing to accept LTC payment to save transaction time< Mining:

special algorithm creates the unique charm of LTC, which is also the key to stand out from Shanzhai coins. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory, each hash is used as the input seed, and then needs a lot of memory to store another seed pseudo-random sequence, Generate pseudo-random points of sequence and output hash value. The key is that scrypt algorithm needs a lot of memory while sha256 algorithm does not. So in this era when BTC mining of graphics card is coming to an end, LTC mining is about to usher in a golden period of development. Because of the high cost of memory, any ASIC or FPGA has no advantage over graphics card mining. LTC has advantages, at least in the foreseeable future
3. The biggest threat of bitcoin is 51% attack:
some shanzhais are killed by 51% attack. To be honest, LTC is a worry for the development of LTC and BTC, of course. However, the specific problems they face are different: BTC can avoid 51% attack through technology upgrading (such as end block reconstruction, careful node upgrading, and calculation difficulty), However, there is no way to evade LTC technology. However, e to the scattered computing power of graphics card mining and the increasing difficulty, this problem needs to be paid attention to, but don't worry too much. With the use of ASIC in BTC, the risk of 51% attack is increasing. I hope BTC development team can solve this problem as soon as possible.

4. Digital currency platform development needs professionals to be responsible for, but now digital currency technology has matured, the difficulty of development has become very simple, has become a standardized technology. Today's digital currency technology is not the highlight, but the application scenario of this kind of digital currency
the birth and popularity of bitcoin all over the world depends on the concept, which is in the foreword of the times. However, bitcoin has been preconceived and cannot be replaced by other digital currencies. Although some counterfeit currencies were popular for a while later, they slowly went down in the end, only bitcoin strengthened. Puyin is another shortcut, as a standard system of digital currency appears, behind the endorsement of related tea assets, its value is recognized by the society.
