Abstract

The invention discloses a blockchain-based anonymous information transmission method and device, and a readable storage medium. The method comprises the following steps: receiving, by a client, information distributed by a blockchain mechanism, a first public key list and a ring signature parameter required for generating a ring signature, and obtaining information to be transmitted correspondingto the information distributed by the mechanism according to the operation of a user of the client; performing ring signature on the information to be transmitted by using the ring signature parameter, other user pubic keys in the first public key list and a private key corresponding to the public key of the client to obtain an information signature; and sending the information to be transmitted and the information signature to the mechanism, so that the mechanism, receives the information to be transmitted and the information signature and uploads the information to be transmitted and the information signature to a blockchain after determining that the information signature is in an effective state. By adoption of the blockchain-based anonymous information transmission method and device disclosed by the invention, the anonymous information transmission is realized; and by writing the information to be transmitted and the corresponding information signature into the blockchain, the non-tampering of the information to be transmitted is achieved by the characteristics of the blockchain.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain-based anonymous information transmission method, device and readable storage medium. Background technique [0002] In the traditional information transmission process, it is difficult to achieve the anonymity of the identity of the user who transmits the information. In the process of information transmission, a trusted third-party organization is needed to ensure the anonymity of the identity of the user in the information transmission. But a completely trusted third party does not exist in real life. For example, in the voting process, in order to ensure the anonymity of voting users, participating institutions need to be divided into information distribution centers to be transmitted, voting systems and vote counting systems. For example, in the general identity-anonymous voting scenario, in order to protect the privacy of voting users, it is genera...
