4. It means that digital currency has a very big rise in a short period of time, and the growth rate is very large, which is beyond the imagination of ordinary people
however, digital currency belongs to the scope of speculation, because it can only be used as currency and has purchasing power unless it is issued by the state. The digital currency issued now has not been recognized by the state
digital currency can only be sold at a price higher than your purchase price to make money. But digital currency itself does not have any value. Unlike stocks, it is your ownership of listed companies. So if you can't find someone to buy digital currency, it's worthless.

1. There should be agreement and authorization relationship between banks and businesses

2. Users, businesses and e-cash banks all need to use e-cash software

E-cash bank is responsible for the transfer of funds between users and businesses

4. E-cash is anonymous to users, and the use of e-cash consumption can protect users' information

Electronic cash exists in the form of digital information and circulates through the communication network. In its life cycle, e-cash has to go through three processes: withdrawal, payment and deposit, involving users, businesses and banks. The basic circulation mode of e-cash: the user and the bank execute the withdrawal agreement to withdraw e-cash from the bank; The user and the merchant execute the payment agreement to pay e-cash; The merchant and the bank execute the deposit agreement and deposit the e-cash obtained from the transaction into the bank

e-cash system can be divided into account based e-cash system and voucher based e-cash system according to its transaction carrier.

DataGrid data formatting expression

data formatting expression

. Net framework formatting expression, which is applied to data before it is displayed in the column. This expression consists of optional static text and a format specifier in the following format:

{0: format specifier}

zero is the parameter index, which indicates the data element to be formatted in the column; Therefore, zero is usually used to indicate the first (and unique) element. Format specifier is preceded by a colon (:), which consists of one or more letters indicating how to format data. The format specifiers you can use depend on the type of data you want to format: date, number, or other type. The following table shows examples of formatting expressions for different data types. For more information about formatting expressions, see formatting types

{0: format specifier}

when we present data, we should not present unmodified data to users. For example, if we directly display "10000" in the amount of 10000 yuan, it may cause users to regard it as 1000 yuan or 100000 yuan, causing users to have trouble reading data. If we retouch NT $10000 and output it as NT $10000, it will not only make it easier to read, but also rece users' chances of making mistakes
the following screen is the result of retouching:
in addition to separating records by color in DataGrid web control, the above data mainly decorates the data of date, unit price and subtotal fields for easier reading. To modify the output of a field, just set the dataformatstring property of the field; The syntax is as follows:

dataformatstring = & quot{ 0: format string} & quot

we know that {0} in the dataformatstring represents the data itself, and the format string after the colon represents the format you want the data to display; In addition, after the specified format symbol, you can specify the number of decimal places to be displayed. For example, the original data is "12.34". If the format is set to {0: N1}, the output is "12.3". The commonly used numerical formats are as follows:

format string data results
& quot{ 0:C}" 12345.6789 $12,345.68
"{ 0:C}" - 12345.6789 ($12,345.68)

9. The basic concept of e-cash system e-cash, also known as e-money or digital cash, is a very important electronic payment system. It can be seen as the electronic or digital simulation of real money. E-cash exists in the form of digital information and circulates through the Internet. But it is more convenient and economical than real money. Its simplest form includes three main bodies: business, user and bank; And four security protocol processes: initialization protocol, withdrawal protocol, payment protocol, deposit protocol. The first e-cash scheme was proposed by Chaum [2] in 1982. It uses blind signature technology to realize it, which can completely protect the privacy of users. But this kind of completely anonymous e-cash also provides convenience for many criminals. They use the complete anonymity of e-cash to carry out some illegal and criminal activities, such as corruption, illegal purchase (such as buying drugs, arms, etc.), extortion, etc. Even if the police get the stolen money, they can't catch the criminals. For this reason, a reasonable e-cash system should be incomplete or conditional anonymous. In 1995, Stadler et al. [3] proposed the concept of fair blind signature, which can be used in conditional anonymous payment system. In 1996, Camenisch et al. [4] and Frankel et al. [5] independently proposed the concept of fair off-line electronic cash for the first time, and gave two schemes. The anonymity of users in fair e-cash is incomplete. It can be revoked by a trusted third party (TTP), so as to prevent criminal activities by using the complete anonymity of e-cash. In its life cycle, e-cash has to go through three processes: withdrawal, payment and deposit, involving users, businesses and banks. The basic circulation mode of e-cash is shown in Figure 1. The user and the bank execute the withdrawal agreement to withdraw e-cash from the bank; The user and the merchant execute the payment agreement to pay e-cash; The merchant and the bank execute the deposit agreement and deposit the e-cash obtained from the transaction into the bank. The basic process of e-cash design is as follows: 1. With draw protocol: users withdraw e-cash from their bank account. In order to obtain the legal e-cash with bank signature on the premise of anonymity, the user will interact with the bank to implement the blind signature protocol, and the bank must be sure that the e-cash contains the necessary user identity. The general withdrawal agreement is divided into the following two sub agreements: * account opening agreement. This step is usually computationally expensive and is used to provide users with an electronic license containing their identity information* Withdrawal agreement. This step is just a simple blind signature process, users can extract e-cash from their accounts. 2. Payment protocal: users use e-cash to purchase goods from stores. It is usually divided into two sub protocols: * verifying the signature of e-cash, which is used to confirm whether e-cash is legal or not* Knowledge disclosure protocol. The buyer will disclose some information about his identity to the seller to prevent the buyer from abusing e-cash. 3. Deposit protocol: users and businesses deposit e-cash into their own bank accounts. In this step, the bank will check whether the deposited e-cash is used legally. If illegal use is found, the bank will use reuse detection protocol to track the identity of illegal users and punish them.
