In the above embodiment, the block to be uploaded to the blockchain network 4 is checked by the corresponding client 1, and the checked block is transmitted to the blockchain network 4, thereby reducing the uploading of false data or erroneous data.
In the above embodiment, when a new block is obtained through the server 2, the new block can be synchronized to at least one corresponding client 1, so that the server 2 can be used as a transfer device, and the server 2 does not participate in consensus, if the server 2 detects that the new block needs to be checked through the newly generated block, the new block can be synchronized to the client 1 involved in the transaction in a manner of under-link synchronization, so that the corresponding client 1 checks the oiling transaction information in the new block, and then whether the transaction is truly and reliably is determined according to the check result fed back by the corresponding client 1 is received, and then the new block corresponding to the authentic and reliable transaction is uploaded to the blockchain network 4; the whole process greatly simplifies the complexity of uplink storage of the oiling transaction information corresponding to the transaction.

In the above embodiment, for any one of the clients 1, when it receives the verification request issued by the first sending module 21, the client 1 may use the verification module 11 to verify the fueling transaction information according to the verification request, and send the verification result to the second sending module 22, so that the second sending module 22 determines whether the fueling transaction information in the block passes the verification according to the verification result sent by the corresponding client 1.
In the above embodiment, the first verification acquiring unit 111 in the verification module 11 may directly acquire the block in the server 2 that is not transmitted to the client and that stores the information including the fueling transaction, that is, the first verification acquiring unit 111 in the verification module 11 may directly acquire the block before the transmission of the first transmitting module 21;
then, the first analyzing unit 112 analyzes the block before the first sending module 21 sends to obtain the fueling transaction information in the block before the first sending module 21 sends, and uses the calculating unit 113 to calculate the checking information of the fueling transaction information in the block before the first sending module 21 sends to obtain the checking information, and marks the checking information as the first checking information;
then, the first sending module 21 sends the block to at least one corresponding client 1, so that the second verification acquiring unit 114 in the client 1 acquires the block sent by the first sending module 21, and adopts the second analyzing unit 115 to analyze the block sent by the first sending module 21 to obtain the verification data in the oiling transaction information in the block, and at the moment, the verification data is recorded as second verification information;
