A transaction transmitted by a user node in a blockchain network and transaction verification information corresponding to the to-be-verified transaction are acquired. The transaction verification information includes a state read set, a state write set, an initial transaction execution result, and a block identifier of a target block. A first block header of the target block includes the block identifier. A second block header is determined from a block header chain of a light node in the blockchain network. The state read set and the state write set are checked based on a first state snapshot in the second block header. The transaction service is executed to obtain a target transaction execution result corresponding to the transaction service and to-be-written state data. Legitimacy of the to-be-verified transaction is checked based on the initial transaction execution result, the target transaction execution result, the state write set, and the to-be-written state data.

A liquid crystal display panel and a display device are provided by the present disclosure. The liquid crystal display panel includes a first substrate, a second substrate, a liquid crystal layer, and a sealing structure. The sealing structure includes an inner retaining wall, an outer retaining wall, and a frame adhesive. The inner retaining wall is located in a frame area and surrounds a display area. The outer retaining wall surrounds the inner retaining wall and is disposed at intervals with the inner retaining wall. An accommodating space is provided between the outer retaining wall and the inner retaining wall. A bottom of the accommodating space is provided with a groove surrounding the inner retaining wall. The frame adhesive is located in the accommodating space.

A data archiving method includes: finding, in local space when an archiving task for a target block header exists, current state trees of block headers, the current state trees including a current state tree that the target block header points to and a current state tree that a first block header before the target block header points to; reconstructing new state trees according to the found current state trees, node reuse information between the current state trees, and target state data corresponding to a second block header after the target block header; and archiving the current state trees stored in the local space to a target archiving server, and deleting the current state trees in the local space after successful archiving.

Examples of the present disclosure provide a contact matching method. The method includes: obtaining a first interest label corresponding to a contact waiting for match and a second interest label corresponding to respective contact other than the contact waiting for match in a matching interface displayed on the client device; comparing the first interest label and the second interest label to obtain at least one contact matching with the contact waiting for match; and displaying a first contact identifier corresponding to the contact waiting for match and a second contact identifier corresponding to respective matching contact or a second contact identifier corresponding to respective matching contact in the matching interface according to a predefined first displaying manner. Examples of the present disclosure also provide a contact matching apparatus. The solution of the present disclosure improves contact matching efficiency and accuracy.

The disclosure is applied to a field of communication technologies and relates to a method for controlling multiple CAN interfaces through a single SPI bus. The method includes: when a reception mailbox of any of a plurality of CAN chips finishes receiving data on a CAN bus, triggering an interrupt by the CAN chip to deliver an interrupt signal; configuring the CAN chip triggering the interrupt through the SPI bus to disable interrupts in the CAN chip, so that the CAN chip exits the interrupt; inquiring the data received by the reception mailboxes of each CAN chip triggering the interrupt, reading the data into a memory buffer of an MCU through the SPI bus, setting a data identifier in the memory buffer of the MCU, and enabling interrupts in the CAN chip triggering the interrupt to allow the CAN chip triggering the interrupt to continue receiving data; and detecting whether the data identifier is present in the memory buffer of the MCU by an application program on the MCU, and copying the data from the memory buffer of the MCU to a memory buffer of the application program if the data identifier is present in the memory buffer of the MCU; otherwise, returning a result as a failure. The invention reads the data into the MCU upon interrupts generated by CAN chips, thereby reducing costs without affecting communication.
