Abstract: A block data archiving method carried out by a blockchain node is described. The method includes determining to-be-archived block data when detecting that a resource of a block stored in the first blockchain node meets a block data archiving condition. The method further includes sending an archiving request to one or more other blockchain nodes; negotiating a consensus with the blockchain node in the same group based on received consensus response information fed back by the blockchain node in the same group one or more other blockchain nodes; and sending the to-be-archived block data to a third-party storage server for archiving in accordance with determining that a consensus is reached and a consensus result that the first blockchain node is a consensus blockchain node is obtained. The consensus result is used to determine the first blockchain node or any blockchain node in the same group is a consensus blockchain node.

Abstract: This application provides a service deployment method and apparatus. The method includes: determining a first component node that needs to be deployed currently in a to-be-deployed service; obtaining, from a physical cluster, a physical node set that meets a computing resource requirement of the first component node; and obtaining, from the physical node set according to a current available network resource of each physical node in the physical node set, a physical node to which the first component node is mapped. According to the technical solution provided in this application, in a node mapping process of service deployment, that is, in a process of determining a physical node to which a component node is mapped, a computing resource and a network resource are comprehensively considered.

Abstract: A method for blockchain generation is provided. The method includes: sending, by a client, transaction information to a first node device, where the transaction information includes basic information and digest information; receiving, by the client, an endorsement result sent by the first node device, where the endorsement result includes a signature generated after the first node device successfully performs transaction simulation; and if the endorsement result meets a preset transaction condition, sending, by the client, the digest information and the endorsement result to a second node device, so that the second node device sends, to the first node device the digest information to generate a complete blockchain. In this way, only the digest information is transmitted between the first node device and the second node device. Therefore, the second node device does not obtain the complete transaction information, so that information security is improved.
