The invention discloses a power data transmission method and system based on quantum Byzantine consensus. The method comprises the following steps: a master node signs information needing to be sent and sends the signed information to a backup node; each backup node receives the message and the signature sent by the main node, marks the signature on the message and the signature and integrally sends the message and the signature to the next backup node, data circulation is carried out in sequence according to the mode, the last backup node sends all the messages and the signatures to the first backup node, and the last backup node sends the messages and the signatures to the second backup node. Each backup node collects messages and signatures received by other backup nodes; the signature is a quantum digital signature; after each backup node obtains the information and the signatures received by all the backup nodes, the information and the signatures are integrally sent to a third-party signature verificati
