Abstract: Disclosed are a game data verification method performed by an electronic device. The method includes: generating a target sequence of target nodes in response to a game start instruction; acquiring target game data corresponding to each of the target nodes, the target game data including game state data and encrypted state data; performing authenticity verification on the target game data of a current target node according to the encrypted state data of a previous target node and the game state data of the current target node; performing accuracy verification on the target game data of the current target node according to the game state data of the current target node and game logic; and after determining that all the target game data corresponding to the target sequence is authentic data and accurate data based on an authenticity verification result and an accuracy verification result, determining that the game verification succeeds.
