Cross-border resource transfer authenticity verification method, device and electronic equipment

A method for auditing authenticity of cross-border resource transfers, implemented on a node device in a blockchain, comprising:

• obtaining, by the node device, through a first off-chain process, a target transaction from an auditor of cross-border resource transfers, wherein the target transaction comprises cross-border resource transfer information and identification information, the node device is accessed by the auditor, and the cross-border resource transfer being initiated to a receiver by the initiator through a second off-chain process;
• and
• performing, by the node device, in response to the target transaction and based on the proof information that is stored in the blockchain and corresponds to the identification information, an authenticity verification on the cross-border resource transfer information, by
• determining whether cross-border resource transfer information received from the auditor matches cross-border resource transfer information indicated by the proof information, when the identification information comprises a search index for the proof information, and
• determining whether a credible certificate received from the auditor is a credible certificate generated based on the proof information, when the identification information comprises a credible certificate,
• wherein the proof information is provided by the receiver of the cross-border resource transfer, and comprises proof documents proving a resource transfer relationship between the initiator of the cross-border resource transfer and the receiver of the cross-border resource transfer;
• and
• returning to the auditor a result of the authenticity verification.

A system for auditing authenticity of cross-border resource transfers, comprising a processor and a non-transitory computer-readable storage medium storing instructions executable by the processor to cause the system to perform operations comprising:

• obtaining, through a first off-chain process, cross-border resource transfer information initiated by an initiator of a cross-border resource transfer, the cross-border resource transfer being initiated to a receiver by the initiator through a second off-chain process;
• obtaining, in response to the cross-border resource transfer information, identification information from a blockchain;
• generating a cross-border resource transfer request based on the cross-border resource transfer information and the identification information;
• and
• sending, to an auditor of cross-border resource transfers, the cross-border resource transfer request, causing a node device in the blockchain and accessed by the auditor to perform, based on proof information that is stored in the blockchain and corresponds to the identification information, an authenticity verification on the cross-border resource transfer information by,
• determining whether cross-border resource transfer information received from the auditor matches cross-border resource transfer information indicated by the proof information, when the identification information comprises a search index for the proof information, and
• determining whether a credible certificate received from the auditor is a credible certificate generated based on the proof information, when the identification information comprises a credible certificate,
• wherein the proof information is provided by the receiver of the cross-border resource transfer, and comprises proof documents proving a resource transfer relationship between the initiator of the cross-border resource transfer and the receiver of the cross-border resource transfer.
