party payment institution, it undoubtedly has a certain
bankruptcy risk. The digital currency stored by users
is difficult to be protected, so they can only
participate in bankruptcy liquidation.
2.2.2 Adopt the Double-layer Operation
Mode
The operation of the central bank's legal digital
currency adopts the "central bank to commercial
bank" dual structure model which has been well
applied for a long time. In short, the central bank, as
the back-end, needs to perform the responsibility of
issuing digital currency and supervising its dynamic
flow, while the commercial bank, as a secondary
organization, should play a front-end role to facilitate
the public to access or exchange digital currency,
Therefore, a dual investment and two-tier operation
system is formed in which the central bank and
financial institutions reach front-end and back-end
cooperation and commercial banks connect with the
public.
2.2.3 Account Loose Coupling Model
The central bank's legal digital currency adopts the
loose coupling mode of bank accounts that is not used
by most institutions, that is, it provides users with two
feasible options. One option is to bind the bank
account like the third-party payment, and the other
option is not to bind the account, but to make
independent payment directly by relying on the
central bank's legal digital currency wallet, which
eliminates the "running cost" And quickly shorten the
waiting time. But now the account tightly coupled
mode is adopted by most of the non cash payment
agencies. This means that if the third party payment
is used, the bank account must be tied up, otherwise
it will not be able to pay. This obviously exists natural
business barriers. For example, Alipay and fortune
paid (WeChat payment) can not transfer transactions
across the platform. Therefore, the central bank's
legal digital currency, which completes the payment
task without any intermediate link, can meet the
public's demand for efficiency. Especially after the
popularity of 5g network, there will be a significant
difference in the transaction speed affected by the
clearing step of intermediary or not.
2.2.4 No Interest, No Handling Charge
The legal digital currency of the central bank has no
interest, and no service charge will be charged
whether it is in the exchange process of commercial
banks or paid under commodity transactions, and the
transaction cost is zero. At the same time, because it
is separated from physical materials, it avoids the loss
and difficulties of paper money and coins in the
issuance and circulation, and greatly reduces the cost.
2.2.5 Controllable Anonymity
Anonymity: before the advent of digital RMB, third-
party payment institutions can easily capture the
user's "digital footprint", including a large number of
personal accounts and credit information, so as to
accurately depict the user's exclusive portrait and
promote their own financial products in a
personalized and targeted manner. Let's compare the
actual use of the central bank's legal digital currency.
Users do not need to bind any account. Through the
regional network technology, their personal account
content will be packaged and then encrypted, which
closes the door for third-party payment institutions to
directly obtain user information, prevents third-party
payment institutions from deliberately using or
disclosing private information, and maximizes the
protection of user privacy, Prevent users from being
cheated by telecom payment due to information being
sold.
Controllable: Although the legal digital currency
of the central bank can be anonymous, it cannot be
completely anonymous. If it is completely
anonymous and its transaction is extremely rapid, it
is very likely to facilitate criminals to commit crimes.
Therefore, it must emphasize the core characteristics
of "controllable anonymity". First, protect users'
privacy. Second, the people's Bank of China should
ensure that it has certain control. Therefore, with the
help of encryption, blockchain and other
technologies, the user data traded with digital RMB
is only disclosed to the central bank, monitor the flow
of funds in real time, master the real M0, and
effectively avoid and crack down on money
laundering Corruption and terrorist financing.
2.2.6 Support Offline Payment
Online and offline parallel payment in two ways can
be implemented on the central bank statutory digital
currency, which is significantly different from the
mobile payment led by Alipay and fortune paid
(WeChat payment). There is no need to connect to the
network. Even if there are extreme conditions such as
earthquakes, if the mobile phone is available, the user
can carry out the digital RMB transfer through mobile
phone operation. This also determines that the daily
trading limit of digital RMB is not high, which is
mainly used in small and high-frequency retail
scenarios.
