The invention provides a block chain abnormal transaction recognition method and device, a storage medium and electronic equipment, and the method comprises the steps: obtaining to-be-recognized block chain transaction data in response to a transaction recognition instruction; identifying the block chain transaction data by using a transaction identification model to obtain an identification result of the block chain transaction data, the transaction identification model being obtained by training by using a training sample set, and the training sample set comprising transaction sample data provided with a first label and transaction sample data provided with a second label; the first label represents that the transaction sample data to which the first label belongs is normal transaction data, and the second label represents that the transaction sample data to which the second label belongs is abnormal transaction data. By applying the method provided by the embodiment of the invention, the to-be-identified transaction data is identified through the transaction identification model obtained by training the training sample set, so that the identification accuracy of the transaction data can be effectively improved.
Description
technical field [0001] The present invention relates to the technical field of data processing, in particular to a blockchain abnormal transaction identification method and device, storage medium and electronic equipment. Background technique [0002] With the development of computer science and technology, more and more users conduct online transactions. For example, they can conduct transactions through blockchain, which brings great convenience to users. In order to ensure the security of transactions, it is usually necessary to Block chain transaction data for identification. [0003] In the existing technology, the identification of abnormal transactions is usually carried out by setting rules and strategies, quantitative indicators, etc. However, such methods usually require manual intervention and cannot cope with diversified risks. The identification accuracy of blockchain abnormal transaction data Low. Contents of the invention [0004] The technical problem to ...
