It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Example one

Fig. 1a is a flowchart of a currency circulation monitoring method based on a block chain according to a first embodiment of the present invention, fig. 1b is a schematic diagram of a currency circulation monitoring method based on a block chain according to a first embodiment of the present invention, and fig. 1c is a schematic diagram of a digital currency block chain network according to a first embodiment of the present invention. The embodiment can be suitable for recording the currency circulation condition, and is particularly suitable for monitoring fraudulent activities and illegal behaviors related to the currency circulation, for example, illegal activities such as money laundering, black money and the like can be monitored by recording the currency ownership and counting the account circulation amount, and judicial evidence is provided for fighting against illegal behaviors such as theft, money robbery and the like. The method can be executed by the currency circulation supervision system based on the block chain, which can be realized in a software and/or hardware manner and can be integrated on the electronic equipment.

Specifically, as shown in fig. 1a and 1b, the currency circulation monitoring method based on a block chain according to the embodiment of the present invention may include the following steps:

s110, generating a physical circulation record transaction request including physical currency circulation data, sending the physical circulation record transaction request to the block chain network, and enabling the block chain network to execute the currency circulation record transaction request to write the physical currency circulation data into the block chain.

The currency circulation is caused by commodity circulation and fund flow, and the currency movement as circulation means and payment means may include circulation means such as deposit, withdrawal, payment, and the like.

Physical currency, which may also be called physical currency to some extent, refers to currency having a value equal to that of a common commodity as currency. In the present embodiment, the physical currency mainly refers to currency, i.e. national-issued legal currency, such as rmb, which is the currency of china, and U.S. dollars, which is the currency of the united states. Specifically, the legal money issued by the country is divided into paper money and coins (metal money).

In order to meet the demand for social informatization and digitization, in the present embodiment, physical currency circulation data may be recorded when physical currency is circulated. Wherein the physical currency circulation data includes: the currency crown word number of the physical currency, the physical currency image, the currency holder identity information and the circulation time. The crown word number is the code on the paper money of the RMB, the "crown word" is two or three English letters printed on the paper money for marking the printing batch, arranged and printed according to certain rule by the bank note printer; the number is an Arabic numeral serial number printed behind the crown word and used for indicating the arrangement sequence of each banknote in the same crown word batch. The money holder can be an individual or a collective unit, and correspondingly, the identity information of the money holder can be the identity card number of the holder or the credit code of a legal person. Specifically, the physical currency circulation data may be acquired and entered into the blockchain in a variety of ways, such as by device input, manual entry, and the like.

And when physical currency circulation is carried out, generating a physical circulation record transaction request according to the acquired physical currency circulation data, and sending the physical circulation record transaction request to the block chain network. As can be appreciated, the physical currency records transaction request is for requesting a blockchain to record the physical currency transactions. After receiving the physical circulation record transaction request, the block chain network writes the physical currency circulation data into the block chain, and the paper currency and cash circulation process is completed.

The block chain is a comprehensive framework and a novel application mode of computer technologies such as distributed data storage, a consensus mechanism, an encryption algorithm, point-to-point transmission and the like. In the currency circulation supervision method based on the block chain, each node can record and track information related to physical currency and digital currency, user account information and currency crown numbers owned by the user account information and the user account information can be stored on the block chain, and changes of currency ownership are recorded and tracked, so that a supervisor can monitor and manage circulated currency in real time.

For ownership of physical currency, specifically when a note is issued in cash to a user at a bank or ATM machine, an associated record is made between the note's cash-in-place number and the currency-holding party account and the record is linked into a blockchain network based on a distributed ledger. The record helps identify the current owner of the note in cash and helps to verify that the note is in valid currency. Valid currency is relative to invalid currency, which includes: physical currency and counterfeit notes that have been damaged, revoked, and destroyed. When a user deposits a banknote cash into a bank, the corresponding digital currency associated with the banknote cash is dispensed and associated to the bank.

Due to the chronological recording of currency circulation activities in the blockchain, currency circulation data can be completely recorded by tracking currency in the blockchain distributed ledger. The data may be synchronously recognized into a multi-node blockchain network. Once currency generates circulation phenomena such as storage, extraction, transfer and the like, records are dynamically added to the account book of the block chain, so that real-time records are kept, and ownership change and authenticity of the currency are tracked.

S120, generating a digital circulation record transaction request comprising digital currency circulation data, sending the digital circulation record transaction request to the blockchain network, and enabling the blockchain network to execute the digital circulation record transaction request so as to write the digital currency circulation data into the blockchain.

The digital currency is virtual currency based on a node network and a digital encryption algorithm, digital representation of value and electronic currency.

The digital currency account is a carrier for storing digital currency and providing digital currency application functions, and can meet the requirements of safer and more convenient digital currency operation and application in the digital economy era. The digital currency account is associated with the user bank account, and the currency in the user bank account is converted into the equivalent digital currency in the digital currency account.

The digital currency account may be used for electronic collection of digital currency, storing transaction records. The equivalent digital currency in the digital currency account associated with the user bank account can be used for electronic transactions, payments, and the amount, status and user bank account are kept consistent in real time.

Illustratively, upon completing payment in digital currency in a digital currency account, there is a need to obtain digital currency circulation data sent by the payment device during the course of a digital currency circulation by a currency holder. Wherein the digital money circulation data includes circulation amount and circulation money holder identity information. And generating a digital circulation record transaction request according to the digital currency circulation data, and sending the transaction request to the blockchain network. As will be appreciated, the digital currency notes transaction request requests that the blockchain record the digital currency notes transaction. After receiving the transaction request of the digital circulation record, the block chain network writes the digital currency circulation data into the block chain, and the single-time digital currency circulation record is completed. The digital currency flow data in the digital currency flow record transaction request may be synchronously recognized into the multi-node blockchain network. Once the digital currency generates circulation phenomena such as storage, extraction, transfer and the like, records are dynamically added to the account book of the block chain, so that real-time records are kept, and ownership change of the digital currency is tracked. It is noted that the total amount of digital currency in the entire blockchain is equal to the generalized currency supply.

Based on the above technical solution, as shown in fig. 1c, preferably, the banking and financial administration can use the digital currency block chain network system to perform real-time monitoring and management on the physical currency and digital currency circulating, decide a currency policy and supply, and control the total amount of the currency.

Specifically, the currency data to be supervised is determined according to the currency supervision request of the supervision party. The crown word number of the currency can be used as a means for tracking currency circulation, and the currency to be supervised can be identified during inquiry and verification so as to determine the data of the currency to be supervised. And generating a supervision transaction request according to the currency data to be supervised, and sending a supervision transaction request comprising the currency data to be supervised to the blockchain network, so that the blockchain network inquires the currency data to be supervised. And acquiring a query result, and sending the query result of the currency data to be supervised to the supervisor so that the supervisor carries out supervision processing. The advantage of this arrangement is that tracking and associating physical and digital currencies through the distributed ledger can help banking and financial regulatory authorities identify the distribution and flow paths of currencies and direct the flow of funds.

Based on the above technical solution, it is preferable that the authorized entity, such as government agency, judicial agency, financial institution, public institution, commercial institution, company, user, etc., can access the digital currency blockchain network system. The Network in the system includes, but is not limited to, the internet, a mobile Network, a 5G (5th generation mobile networks, fifth generation mobile communication technology), a 4G (4th generation mobile networks, fourth generation mobile communication technology), a WAN (Wide Area Network), a LAN (Local Area Network), and the like. Each type of entity unit can acquire data information from the block chain only if authorization and legal permission exist, generates an inquiry transaction request according to the required data by combining respective requirements, and sends the inquiry transaction request comprising the required data to the block chain network so that the block chain network inquires the required data.
