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.

Abstract: Provided are an audio calibration method and device. The method includes: transmitting an audio calibration signal to a first loudspeaker and a second loudspeaker such that the first loudspeaker and the second loudspeaker generate sound signals; determining first loudspeaker sound information through a sound signal generated by the first loudspeaker and acquired by a first microphone and a sound signal generated by the first loudspeaker and acquired by the second microphone; determining second loudspeaker sound information through a sound signal generated by the second loudspeaker and acquired by the first microphone and a sound signal generated by the second loudspeaker and acquired by the second microphone; and determining a calibration parameter of the first loudspeaker or a calibration parameter of the second loudspeaker according to the first loudspeaker sound information and the second loudspeaker sound information.

Abstract: Transaction systems and methods for advancing a committed time in the future are described herein. In the present transaction systems and methods, the first end can be permitted to pre-hatch a time capsule signature before the committed time. The time capsule signature scheme here is conducted based on an identity-based trapdoor relation (IDTR). Moreover, an extended time capsule signature scheme is conducted based on an extended identity-based trapdoor relation (IDTR). By using an extended IDTR primitive, the present transaction systems and methods can distinguish the time capsule signature is validated before or after the committed time t.

Abstract: A thermoplastic biobased material-containing composition comprising chemically-modified feathers and/or dried distillers grains and a process for forming the thermoplastic biobased material-containing composition. More specifically, the thermoplastic biobased material-containing composition comprises one or more of the following chemically-modified biobased materials: (a) acylated biobased material having a % Acyl Content that is at least 3% and a % Weight Gain that is at least 1%, and; (b) etherified biobased material having a % Weight Gain that is at least 2%; and (c) graft polymerized biobased material having a % Monomer Conversion that is at least 40%, a % Grafting Efficiency that is at least 30%, and a % Grafting that is at least 10%.
