Abstract

The invention discloses a bill processing method and device based on a block chain. The method comprises the following steps: the authorization server sends a bill generation instruction to the firstuser, the first user generates a first ciphertext in which a first bill random number and a first bill amount are recorded; the first bill information is sent to an authorization server; and the authorization server generates a signature of the first bill information after determining that the first bill information passes the verification, and sends a bill chain transaction to the block chain system, and the block chain system generates a first bill certificate according to the first bill information after determining that the signature of the first bill information in the bill chain transaction passes the verification, and stores the first bill certificate. The technical scheme is used for guaranteeing bill transaction privacy in a block chain system.
