Abstract

The present invention is related to an electronic transaction system using a blockchain to store transaction records. The electronic transaction system includes a computing device having a verification module, a processing module and a broadcasting module, and the blockchain includes a plurality of user nodes connecting to the computing device. The verification module is configured to generate notification information according to a transaction event, and the notification information is transmitted to a first and second user nodes. The processing module is configured to generate a first and second transaction currency values, the sum of which is zero, after the verification module receives the verification information from the first and second user nodes. The broadcasting module is configured to record transaction information associated with the transferring of the first and second transaction currency values in a data block, and to broadcast the data block to each of user nodes.

Dependent claims

An electronic transaction system using a blockchain to store transaction records, the electronic transaction system comprising a computing device, and the blockchain comprising a plurality of user nodes connecting to the computing device by a peer-to-peer network, the plurality of user nodes having at least a first and second user nodes that correspond to a first and second user devices, respectively, wherein the computing device comprises:

a verification module configured to generate two notification information that correspond to each other according to a transaction event, and are transmitted to the first and second user devices, respectively, and the verification module receives verification information verified and returned by a first and second users through the first and second user devices, respectively, and each notification information includes a transaction value;
a processing module configured to generate a first and second transaction currency values according to the transaction value after the verification module receives the verification information, wherein the sum of the first and second transaction currency values is zero;
and
a broadcasting module configured to record a transaction information associated with the transferring of the first and second transaction currency values to the first and second users, respectively, in a data block, and to broadcast the data block to each of user nodes.
