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: A first data management apparatus in a plurality of data management apparatuses corresponds to a first blockchain node in a blockchain network, and a second data management apparatus corresponds to a second blockchain node in the blockchain network. A storage mounted to the first data management apparatus and a storage mounted to the second data management apparatus are configured to form a storage resource pool of the blockchain network. A method includes a target data management apparatus in the plurality of data management apparatuses that receives a data operation request; and that the target data management apparatus obtains a storage address of a plurality of data shards of target data from the blockchain network based on the data operation request, and performs I/O on the target data in the storage resource pool based on the storage address of the plurality of data shards.

Abstract: A blockchain maintenance method adds a target blockchain node group of a first tenant to a channel. In the method, a management node sends new channel configuration information of the channel to an execution node of a second tenant. The execution node of the second tenant generates incremental configuration information of the channel based on the new channel configuration information and old channel configuration information of the channel, and sends the incremental configuration information to a consensus organization. Each blockchain node group that has joined the channel obtains, from the consensus organization, a block including the incremental configuration information, and adds the block to a stored blockchain, to reach a consensus that the target blockchain node group joins the channel. The target blockchain node group is configured based on the incremental configuration information to join the channel.

Abstract: A blockchain network management method includes a management platform receiving an inter-blockchain application submitted by a user; and invoking a blockchain platform management interface based on the inter-blockchain application to install an inter-blockchain contract for a first blockchain network and a second blockchain network separately. The inter-blockchain contract is used by the first blockchain network and the second blockchain network to establish a connection to a relay apparatus separately, and perform an inter-blockchain transaction via the relay apparatus. The management platform installs an inter-blockchain contract for different blockchain networks such as a heterogeneous blockchain network through a same set of blockchain platform management interfaces, to integrate an inter-blockchain capability, and truly streamline services of the blockchain networks. Data can be migrated between different blockchain networks without adapting to a heterogeneous kernel.

Abstract: A blockchain network management method includes receiving a user registration request, where the user registration request includes a user type of a user, and the user type is based on a deployment manner of a blockchain network managed by the user; registering a corresponding organization for the user based on the user registration request, where the organization is associated with resource space corresponding to the user type; and invoking a processing interface of the resource space to execute corresponding service logic. In the method, an organization with a consistent structure is registered for an on-cloud user or an off-cloud user, and the organization is bound to resource space of a corresponding user type, to perform service processing through a processing interface of the corresponding resource space.
