description The invention provides a privacy protection transaction verification method and device based on a block chain, equipment and a medium, and relates to the field of block chains. The method comprises the following steps: after a request transaction instruction sent by a user is obtained, analyzing a privacy protection model of a private domain node by adopting a ZKML technology, and generating a corresponding key pair; and then, according to the request transaction instruction, the privacy protection model and a certification key contained in the key pair, processing data to obtain a data processing result, and sending the data processing result and a verification key contained in the key pair to a public domain node of the block chain network. And finally, when a target verification result returned by the public domain node is received and the target verification result is a preset result, executing the request transaction instruction. According to the method provided by the invention, the problem of privacy p
