e (57) Abstract: Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage 
Media, for blockchain network digital ticket transfer. One of the methods includes receiving a request from a client device to transfer 
a digital ticket from a blockchain network to a target server by a blockchain network node. The blockchain network node determines 
whether the client device is authorized to transfer the digital ticket based on a digital signature in the request, and transmits a notification 
message to the target server if the digital signature is valid. The blockchain network node receives a confirmation message from the 
Target server indicating validity of the client device, and transfers the digital ticket to the target server.
