An obtaining method and apparatus for a block group header, a storage medium, and an electronic device are disclosed. The method may include, performing a determination as to whether a target node in a blockchain system meets a preset condition, where the preset condition is indicative of at least one of, the target node receiving a block group header but failing to receive a preset number of legal blocks, or the target node failing to receive the block group header; identifying a cause of an event that the target node fails to receive the block group header, in response to the determination that the target node fails to receive the block group header, where the cause of the event comprises at least one of, the target node failing to receive the block group header, or the blockchain system failing to generate the block group header; and determining a method for acquiring by the target node, the block group header that fails to be received, according to the cause of the event.

Obtaining method and apparatus for block group header, storage medium, and electronic device

The current invention discloses methods and devices for adding a new member to a group, e.g. a chat group associated with a chat program. The new member may be added through a barcode-scanning process or an existing-member-invitation process. After the new member is added to the chat group, a server may send notification messages to mobile devices associated with the existing members of the group. The contents of the notification messages may vary based on the processes by which the new member is added, the number of existing members, and the direct-contact relationships the new member has with the existing members. The current invention provides simplified methods and devices for adding the new member, avoiding cumbersome operations and protecting member privacy at the same time.

Various embodiments provide methods, apparatus, and systems for logging in an application account. A request for logging in an application account sent from a first terminal can be received. It is detected if the first terminal can be included in frequently used terminals corresponding to the application account. First verification information can be sent to a second terminal bound with the application account, when it is detected the first terminal is not included in the frequently used terminals corresponding to the application account. Second verification information can be received from the first terminal to detect if the second verification information matches the first verification information. When it is detected that the second verification information matches the first verification information, the request for logging in the application account can be responded.
