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.
