Problems solved by technology

The existing digital currency wallet solutions all back up the private key online to form a backup digital currency wallet. Although many security measures have been taken to ensure the security of applications and data, numerous attack cases and system vulnerabilities show that this still cannot guarantee the security of digital currency wallets. Security of Digital Currency in Currency Wallet
[0004] And now it is difficult for small and medium-sized enterprises to raise funds, because these companies are subject to information disclosure and financial supervision, and need to solve various problems in their management and operation. It is a problem that needs to be solved that the circulation of funds on the platform can be supervised

Embodiment 1

[0031] see figure 1 , figure 1 A schematic diagram of the steps of a blockchain-based virtual voucher method provided by the embodiment of the present invention is as follows:

[0032] Step S100, receiving a transfer application for transferring the first quantity of virtual certificates from the user node in the first blockchain to the receiver node in the second blockchain;

[0033] Specifically, the first quantity can be any number, and the virtual certificate can be a virtual share issued by the issuer, the user is the issuer of the virtual share in this embodiment, and the receiver is the buyer of the virtual share in this embodiment, For example, the issuer issues 100,000 virtual shares, that is, the issuer issues 100,000 virtual certificates on the blockchain, and the purchaser purchases 10,000 of the 100,000 virtual certificates issued by the issuer.

[0034] In some implementations, virtual credentials can be transferable digital information on the blockchain, often...

Embodiment 2

[0048] see figure 2 , figure 2 A schematic diagram of the detailed steps of a blockchain-based virtual voucher method provided by the embodiment of the present invention is as follows:

[0049] Step S200, according to the valuation amount in the first block chain, and the preset selling price of the overall virtual stock in the first block chain, docking with the virtual certificate according to the preset conversion ratio;

[0050] Specifically, the first block chain can be the block chain library where the issuer of the virtual shares is located, the preset price of the overall virtual stock sold in the first block chain can be set according to the overall percentage, and the preset exchange ratio can be The ratio of virtual shares to virtual certificates set by the issuer.

[0051] In some implementations, the virtual share issuer is valued at 5 million virtual shares in the first blockchain library, and the preset total virtual shares sold in the first blockchain are 5...

Embodiment 3

[0089] see image 3 , image 3 A schematic diagram of a blockchain-based virtual voucher system module provided by the embodiment of the present invention is as follows:

[0090] The receiving module 10 is configured to receive a transfer application for transferring the first quantity of virtual certificates from the user node in the first blockchain to the receiver node in the second blockchain;

[0091] The response module 20 is used to call the smart contract program of the agreement between the first block chain and the second block chain in response to the received transfer application;

[0092] The conversion module 30 is used to convert the equivalent value of the first quantity of virtual certificates into the second quantity of common data based on the smart contract program called;

[0093] The writing module 40 is used for writing the record of reducing the virtual certificate of the first amount in the first virtual certificate database of the user node, and wri...

Abstract

The invention provides a virtual voucher method and system based on blockchain, and relates to the field of blockchain. The method comprises the following steps: receiving a transfer application for transferring a first number of virtual vouchers from a user node in a first blockchain to a receiver node in a second blockchain; in response to the received circulation application, calling an intelligent contract program of a protocol between the first block chain and the second blockchain; based on the called smart contract program, equivalently converting the first number of virtual certificates into a second number of general data. According to the method, the blockchain intelligent contract technology can be fully utilized, fund flow of a first-level transaction platform and a second-level transaction platform is completed through the blockchain technology, no trader participates in a virtual certificate in the process, and the process has the characteristics of centralized issuer, non-anonymity and uncertain total amount. In addition, the invention further provides a virtual certificate system based on the blockchain. The virtual certificate system comprises a receiving module, aresponse module, a conversion module and a writing module.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a block chain-based virtual voucher method and system. Background technique [0002] In the current blockchain system, the address of the virtual currency is the public key in a set of asymmetric keys, which are generated by the elliptic algorithm. The address and private key of the user account are stored in the virtual wallet (that is, digital currency wallet) file, and the private key is encrypted and decrypted by the virtual currency client software. Currently, digital currency wallet technologies based on blockchain technology are all based on Bitcoin, which can be classified into: web wallets, multi-signature wallets, desktop wallets, and mobile wallets. [0003] Due to the decentralization and anonymity of the entire virtual currency system, once the digital currency wallet is lost, the bitcoins stored in all addresses in the digital currency wallet may be stolen. Onc...
