A method and an apparatus for controlling a data access right are disclosed. The method includes: receiving, by a first proxy node, a first request message from a request node, where the first request message includes an identity of the request node and an identifier of to-be-accessed data; determining a first encrypted ciphertext on a blockchain based on the identifier; determining, based on the identity, whether the request node has a right to read the first encrypted ciphertext; and if yes, initiating a right verification request for the request node to at least one second proxy node, and determining, based on a feedback result of the at least one second proxy node, provisioning of the first encrypted ciphertext. A proxy node is added to the blockchain network, so that a data source can freely grant or revoke the right of the request node without modifying a ciphertext, ensuring information security.

Method and apparatus for controlling data access right to data stored on a blockchain

An information management method includes: receiving an information import request sent by a first agent node, where the information import request includes a first identifier of a user; obtaining a second identifier of the user based on the information import request, and obtaining to-be-imported personal information corresponding to the second identifier of the user; and sending metadata of the user to a block chain node, to store the metadata of the user into the block chain system. In this way, personal information of the user is registered in the block chain system, so that security of the personal information can be effectively ensured, and the user can perform management of and provide external authorized access to the personal information of the user in a unified manner.

Information management method, apparatus, and information management system

A cross-chain transaction method and apparatus. For any node on a first blockchain of blockchains on which a plurality of associated transactions occur, after receiving an association transaction from a consensus node, the node needs to determine, based on an identifier of an anchor transaction included in the association transaction, whether the anchor transaction is a valid transaction. If the anchor transaction is a valid transaction, the node writes a transaction that occurs in the first blockchain into the first blockchain based on identifiers of the blockchains on which the plurality of transactions occur, to ensure that the plurality of associated transactions on the plurality of blockchains are successfully submitted simultaneously.

Cross-chain transaction method and apparatus

A container deployment method increases access speed between isolated containers on a same host. The method includes: receiving a container deployment message including container image information and association information of a container; creating a container for a first service, and a first network namespace and a first IPC namespace corresponding to the container for the first service; creating a first load balancing container corresponding to the container for the first service, and setting a running parameter of the first load balancing container to a parameter of the first network namespace; creating a loopback interface in the first network namespace; determining that the network device has a container that is for a second service and that is associated with the container for the first service; and setting a starting parameter of the first load balancing container to a parameter of a second IPC namespace.

Container deployment method, communication method between services, and related apparatus

A container deployment method and apparatus are disclosed. The method includes receiving a first container creation request that carries a required resource capacity and a required image identifier, where the required image identifier is an identifier of an image corresponding to an application that needs to be run. From a cluster of working nodes, at least two first working nodes whose unused resource capacity is greater than the required resource capacity are selected. A target working node is determined from the at least two working nodes according to images stored on the at least two first working nodes and the required image identifier. A second container creation request is sent to the target working node carrying the required resource capacity and the required image identifier.
