Timestamp processing method and apparatus

Abstract

The embodiment of the invention provides a timestamp processing method and apparatus. The method comprises the following steps: performing hash operation by a sending node on a name and a public key of the sending node to obtain a first hash value; sending the first hash value to a time confirmer; performing hash operation on a to-be-sent service message and the first hash value to obtain a second hash value; and sending the to-be-sent service message, the first hash value and the second hash value to the time confirmer. According to the timestamp processing method and apparatus provided by the embodiment of the invention, the to-be-sent service message is sent to the time confirmer by the sending node, and the time confirmer adds a timestamp to the service message, thereby avoiding the phenomenon that the node randomly modifies the timestamp, in addition, the sending node performs the hash operation on its own name and the public key to obtain the hash value, and the sending node is marked by the hash value, so that other nodes in a block chain network knows nothing about the name and the public key of the sending node, thereby avoiding the attack of the sending node and improving the security of the sending node.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a method and device for processing a time stamp. Background technique [0002] Blockchain is a transaction database in which blocks are combined in chains for sharing by nodes in the system. Specifically, the information (including data or code) generated within a period of time is packaged into a block, stamped with a time stamp, and connected with the previous block, and the page capital of each next block contains the previous block index data, and then write new information in this page, thus forming a new block, connected end to end, and finally forming a blockchain. [0003] In the current blockchain network, when a node sends a message to the blockchain network, it can carry a time stamp in the message to indicate the moment when the node sends the message, so that multiple nodes send the block The messages sent by the chain network w...

Problems solved by technology

[0004] However, some nodes may arbitrarily modify the time stamp carried in the message in order to let other nodes process the message sent by themselves first, for example, modify the time corresponding to the time stamp to be less than the time when the message was actually sent, so that other nodes can Prioritize the message, causing unfairness in the blockchain network
