Data storage method based on block chain, related device and storage medium

Abstract

The invention discloses a data storage method based on a block chain, a related device and a storage medium. The method comprises the steps of in response to a received transaction processing requestof a target merchant for a target cross-border transaction, obtaining the order information of the target cross-border transaction from an overseas transaction platform; obtaining the target logisticsinformation matched with the order number from a logistics service platform; matching the target logistics information with the logistics information in the order information, and verifying the authenticity of the target cross-border transaction according to a matching result; when the verification result is true, providing a service requested by the transaction processing request, and recordingthe service details of the service; and packaging the order information, the target logistics information and the service details into an evidence storage transaction, and sending the evidence storagetransaction to a node of a target block chain, so that the evidence storage transaction is stored in the target block chain based on a consensus mechanism. According to the invention, the transactioninformation subjected to the automatic authenticity verification is stored by using the non-tampering property of the block chain, so that the supervision efficiency is improved.

Description

technical field [0001] The present invention relates to the field of block chain technology, in particular to a block chain-based data storage method, related equipment and storage media.
