Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.
[0022] Such as figure 1 As shown, the blockchain-based transaction conflict detection method includes steps 101-103:
[0023] Step 101, obtaining a transaction read-write set and a preorder read-write set corresponding to the transaction read-write set.
[0024] Transaction refers to the operations generated by the blockchain in the application, such as transfer operations, creation of smart contracts, smart contract calls, account creation, etc. In some embodiments of the p...

The invention discloses a blockchain-based transaction conflict detection method, device, equipment, and storage medium; the method includes: acquiring a transaction read-write set, and acquiring a preorder read-write set corresponding to the transaction read-write set; according to the The pre-order read-write set performs logical operations on the read-set bitmap of the transaction read-write set to determine whether there is a conflict between the pre-order read-write set and the transaction read-write set; if the pre-order read-write set If there is no conflict between the transaction read-write set and the transaction read-write set, the pre-sequence read-write set and the transaction read-write set are merged to obtain the target read-write set; the logical operation result of the bitmap of the read-write set Perform transaction conflict detection, reduce the volume of read-write sets, reduce complexity, and improve the efficiency of conflict detection.
Description
technical field [0001] The present invention relates to the technical field of block chain, in particular to a transaction conflict detection method, device, equipment and storage medium based on block chain. Background technique [0002] Under the framework of fragmented execution, the upper-layer management module pre-analyzes the transaction and distributes it to the unreachable executors of the lower layer. The executor layer needs to generate a read-write set during execution and return it to the upper layer for conflict detection; Larger, when there are many modifications to the transaction ledger, it will cause problems such as large read-write set content, large memory consumption, low efficiency and time-consuming comparison of conflict detection, and the operation of range read operations such as iterators , the organization method of the sketch set and the conflict detection logic of a single key-value are not suitable for the range read operation. On the one hand...
