block chain-based transaction conflict detection method, device, equipment and storage medium

The invention discloses a block chain-based transaction conflict detection method, a device, equipment and a storage medium. The method comprises the following steps: acquiring a transaction read-write set, and acquiring a preorder read-write set corresponding to the transaction read-write set; performing logical operation on a read set bitmap of the transaction read-write set according to the preorder read-write set, and determining whether a conflict exists between the preorder read-write set and the transaction read-write set; if no conflict exists between the preorder read-write set and the transaction read-write set, combining the preorder read-write set and the transaction read-write set to obtain a target read-write set; the transaction conflict detection is carried out through the logical operation result of the bitmap of the read-write set, the volume of the read-write set is reduced, the complexity is reduced, and the conflict detection efficiency is improved. 本发明公开了一种基于区块链的交易冲突检测方法、装置、设备和存储介质；方法包括：
