Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] 1. The steps of a storage method and queuing method of a blockchain transaction are as follows:

[0027] Step S1, each transaction will generate a transaction hash value, take certain digits (for example: the first three digits) of the transaction hash value and write them into the bitmap, and one bit can only store one transaction hash value that meets the conditions. Other transactions that meet the conditions will be queued, for example: take the first three transaction hash values ​​and write them into the bitmap, and the bit 3 (011) can only store transactions with the first three transaction hash values ​​011;

[0028] Step S2, the status code of the bit stored in the transaction is changed from 0 to 1, and the status code of the bit not stored in the transaction is always 0;

[0029] Step S3, the consensus node performs mining, and the consensus node N t...

Abstract

The invention discloses a storage method and queuing method of blockchain transaction. Some bits of a transaction hash value are written into a bit chart, one bit can only store one transaction hash value that satisfies a condition, and other transactions satisfying the condition are queued. Consensus nodes perform mining, a consensus node N which calculates a Merkel root hash value firstly broadcasts the Merkel root hash value and a bit chart of the node to other consensus nodes. By comparing the bit chart, missing or inconsistent data is quickly searched. A block is generated after reachinga consensus. When a transaction volume is large and the transaction is congested, a user can set the priority of a transaction queue according to own needs.

Description

technical field [0001] The present invention relates to the technical field of blockchain. Background technique [0002] In the storage method of existing blockchain transactions, consensus nodes verify the consistency of each other's data through the Merkle root hash value. If the obtained Merkle root hash value is inconsistent, each layer needs to be retrieved from top to bottom The hash value of the leaf node until the underlying error transaction hash value is found, so as to determine which transaction is wrong. Only after the transaction is corrected and the transaction data reaches a consensus can the transaction be stored in the block. This process takes a lot of time and computing power. [0003] Existing blockchain transactions hardly set the transaction queuing method, or simply set different charging levels to change the transaction queuing priority, and cannot flexibly change the transaction queuing priority according to user needs.
