Abstract: This application discloses a method used to remove a target blockchain node group of a first tenant from a channel. In the method, an execution node of a second tenant receives configuration information of the target blockchain node group of the first tenant which is sent by a management node, obtains channel configuration information of the channel from a consensus organization, and generates channel adjustment information based on the channel configuration information and the configuration information of the target blockchain node group. The execution node of the second tenant sends the channel adjustment information to the consensus organization, and the consensus organization generates a block including the channel adjustment information. A blockchain node group of the second tenant obtains the block from the consensus organization, and adds the block to a blockchain stored in the second tenant.
