What is the meaning of local currency of digital currency

1. They don't mean the same thing at all. Digital China refers to the statistical data of China's national economy and people's livelihood. digital currency, however, is only currency or money represented by computer program code.

2.

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

3. The concept of standard digital currency is put forward by acchain, which means that only when all digital currencies are anchored by physical assets can they have real value, that is, the so-called standard digital currency.

4. Puyin is a high-quality Tibetan tea asset, which is stored, identified, evaluated and authorized by three parties. It is a standard digital currency issued by encryption and digitization. Puyin implements the concept of "white paper on standard digital currency" in strict accordance with its operation guidelines, and creates standards for asset digitization
the traditional digital currency is not supported by real assets, especially some counterfeit currencies, which have disappeared after a period of time.

bus route: Gaofeng No.3 → Guangfo line → Nanhai Shunde line of Foshan Chengba, the whole journey is about 9.2km

1. Walk about 10m from the ceramic exhibition center to the Ceramic Exhibition Center Station

< P > 2. Take Gaofeng No.3, pass 3 stops, and reach jihuayuan subway station

3. Walk about 80m, and reach jihuayuan station

4. Take Guangfo line, pass 5 stops, After arriving at Guicheng station, walk about 320 meters to post office station, take Nanhai Shunde line of Foshan Chengba, pass 2 stops, and reach Xiyue station (or take gui04 Road)

6. Today, I encountered a problem when building a database with Oracle

"/ etc / oratab is not accessible", because when installing Oracle, you forgot to execute a root.sh file

(after the graphics installation is finished, it is not finished yet, you need to create a / etc / oratab file. If you do not have this file, you will report an error when using DBCA to create the database in the future, Oratab is used to create database)

[ root@localhost db_ 1]# ./root.sh

Running Oracle10 root.sh script...

The following environment variables are set as:

ORACLE_ OWNER= oracle

ORACLE_ HOME= /home/oracle/oracle/proct/10.2.0/db_ 1

Enter the full pathname of the local bin directory: [/usr/local/bin]:

Copying dbhome to /usr/local/bin ...

Copying oraenv to /usr/local/bin ...

Copying coraenv to /usr/local/bin ...

Creating /etc/oratab file...

Entries will be added to the /etc/oratab file as needed by

Database configuration assistant when a database is created

finished running generic part of root.sh script.

/ etc / oratab this file will change. When we edit it, we will find that it records the name of each database

when we manually delete a database, we need to enter this file to delete the contents of the database. When we use DBCA to delete a database, we don't need to.

& ﹥ 8205< First of all, refer to the operational calculus process of Hoi
III:
1. In each round (hour), each unit of the offensive unit randomly attacks one unit of the defensive unit, assuming that division a is the attacking unit and Division B is the defensive unit
2. According to the ratio of non armor degree of division a and Division B, the possibility of soft attack and hard attack is determined (as shown in the previous figure, if the armored forces are 48% non armor degree, then 48% of them will be killed by soft power)
3. On this basis, the soft and hard attacks of division a and Division B multiplied by the correction value of attack efficiency are regarded as attack points to attack each other
4. Division A and Division B start the attack / defense calculus:
1). Defensive Division B takes defense times defense efficiency correction value as defense points, and offensive division a takes tenacity times defense efficiency correction value as defense points
2) in each attack and defense round, division a uses one attack point in attack, Division B uses one defense point in defense, Division B also uses one attack point in counterattack, and division a uses one defense point in defense
3) when the defender has defense points, it is defined as not breaking the defense. In the case of not breaking the defense, the attack points will have a miss rate of 70% (Steel 4 = 90%)
4) when the defender has no defense points, it is defined as breaking the defense. In the case of breaking the defense, the attack points will have a miss rate of 48% (Steel 4 = 60%)
first of all, let's make a hypothesis: the attack and defense formula of Steel 4 is the same as that of steel 3 (you can see that the definitions of attack and defense parameters are basically the same by consulting Lua file, and the coefficients are slightly different). The following analysis is all based on the attack and defense mechanism and calculation attack of steel 3, which can be verified in the game console<

armor
steel 3 is the same as steel 4, and does not directly rece the damage by half<
the last simulation of a 40 width division against two 20 width divisions (the biggest difference between 3 and 4)
A is 40 width offensive division
B represents two 20 width defensive divisions
to simplify the analysis, the following assumptions are made:
1.
attack and defense efficiency = 1
damage coefficient to Organization = 0.04
2.
SA = 600
ha = 0
BT = 300
org = 40
3.
SA = 300
H A = 0
def = 300
org = 80 (e to B
num = 2
orgdouble)
4. Assuming that ab's non armor degree is 100%, it can pierce armor
so
the damage of a division to organization degree is
(DEF)_ B * 0.1 + (SA DEF) * 0.4) * 0.04 = 6
the damage of Division B to organization degree in each round was
(BT / >)_ A * 0.1) * 0.04 = 1.2
so
after 14 rounds, Division B withdraws from the battle. At this time, Division A's remaining org = 40-1.2 * 14 = 23.2
conclusion:
Division 40 & gt; 2 * 20 width Division & gt; 4 * 10 width Division
