Abstract: Embodiments of this application provide a blockchain-based data processing method, a device, and a medium. The method includes: sending a first channel closing message on a chain-off channel; receiving a second signature in a second state and a second channel closing message that are sent on the off-chain channel, where the second signature is obtained by signing the second channel closing message; and signing a third channel closing message to obtain a first signature in the second state, and sending the first signature. This application can ensure transaction security and improve a transaction processing capability.

Abstract: An encryption and decryption method in a virtualization system is disclosed. The virtualization system includes a VMM and an encryption and decryption virtual machine. The VMM includes a control module, the encryption and decryption virtual machine records a first association relationship between a hard disk image identifier and a key, the key includes an encryption key, and the virtualization system records a second association relationship between the hard disk image identifier and a hard disk image attribute. The control module in the VMM is configured to determine whether to-be-written data needs to be encrypted and forward the to-be-written data, which makes it easy to implement a function and reduces system complexity of the VMM. In addition, encryption or decryption is processed without occupying a resource in the VMM.

Abstract: A method for controlling virtual reality (VR) video playing and an apparatus are provided. In this method, a video server device renders a jump icon in a video image. When a user wants to perform video jump based on video content, a jump icon corresponding to a scene in which the user is interested may be selected to form an input. The video server obtains, based on the input of the user, a jump time of a jump target video corresponding to the jump icon, and plays the jump target video for the user from the jump time. The jump target video may be a video that is being played, or may be another video. According to the application, a video can be switched based on preferences of the user.
