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.

Abstract: Example model invoking methods and apparatus are described. In one example method, a first device verifies model use permission of an artificial intelligence (AI) application based on a model identifier of a to-be-invoked target AI model and a permission verification parameter of the AI application to ensure that the AI application is a valid application that has use permission. When the verification on the model use permission of the AI application succeeds, an encrypted model file of the target AI model is decrypted in a trusted execution environment (TEE) to obtain a decrypted model file. The decrypted model file is directly loaded to a memory to run the target AI model. In the entire process, the decrypted model file of the target AI model is stored in the memory.
