A data provider encrypts source data to obtain a ciphertext of the source data, and uploads the ciphertext of the source data to a data storage platform for storage. Subsequently, in response to a data application request of a data consumer, the data provider encrypts a storage address of the ciphertext of the source data by using a public key of the data consumer, and uploads the encrypted storage address to a blockchain network. The data consumer obtains the ciphertext of the source data from the data storage platform. In the process, a blockchain decentralization capability is used to implement secure and trusted data exchange by using a smart contract that is public and commonly visible to a plurality of parties.

Data processing method and apparatus, device, and medium

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.

A mechanism is provided for reducing network load in a software defined network. The mechanism is executed by a virtual machine hypervisor. The mechanism receives a network broadcast request sent by a source virtual machine node; acquires a first destination address in the network broadcast request; and reads a predefined mapping rule of the first destination address and a second destination address. An address of a node in the software defined network is configured by using the predefined mapping rule. The mechanism derives the second destination address corresponding to the first destination address according to the mapping rule. The mechanism responds to the network broadcast request by using the derived second destination address.
