Abstract

One or more embodiments of this specification provide a blockchain-based message verification method and device, including: determining a private chain message node corresponding to a target message in a pre-established message blockchain private chain; Hash encryption is performed on the node information of the private chain to obtain the Hash value of the private chain message node; the public chain block Hash value is obtained from the private chain block where the private chain message node is located; according to the node information corresponding to the target message the message number and the hash value of the public chain block, obtain the hash ciphertext in the public chain message node corresponding to the target message from the pre-established public chain of the message block; in response to determining that the hash value of the private chain message node is the same as the The Hash ciphertext is the same, and a signal indicating the successful verification of the target message is output. The invention realizes the verification function of the communication information on the basis of ensuring the privacy of the communication information through different blockchains designed on the server side and the client side respectively.

Description

technical field [0001] One or more embodiments of this specification relate to the field of blockchain technology, and in particular, to a method and device for message verification based on blockchain. Background technique [0002] The instant messaging system based on the mobile terminal has become an important communication tool for people. At present, with the development of communication technology and mobile terminal technology, for the consideration of cost and efficiency, more and more fields of communication begin to use the instant messaging system of the mobile terminal, and these fields put forward new requirements for the instant messaging system. [0003] In addition to higher requirements for traditional features such as confidentiality and immutability of communication information, users also require that communication information cannot be known by third parties (including servers). information for verification and traceability. In the prior art, the techn...
