a1, submitting the blocks to a block database, and recording block submission results;
and A2, reading the result of the transaction validity verification, and performing subsequent cross verification when the result of the transaction validity is read, or writing the result into a block submission result.
The specific step thread B of the transaction validity verification comprises the following steps:
b1, performing transaction validity verification in the block, entering the step B2 when the verification is completed, and otherwise entering the step B3;
b2, submitting the submitted transaction validity verification result to a transaction verification database, submitting the transaction execution record to a transaction state database, and recording the submitted transaction validity verification result and the submitted transaction state;
b3, reading the result submitted by the block, performing subsequent cross validation, and writing the validation result of the submitted transaction and the status of the submitted transaction when the result submitted by the block is not read.

when the block submission is successful and the transaction submission status is successful, or the block submission is failed and the transaction submission status is failed, the performance does not need to be optimized;
when the block submission is successful and the verification of the transaction validity is failed, canceling the block submission;
