(57) Abstract: Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage 
media, for implementing a blockchain-based web service. One of the methods includes receiving a web service request for web data by 
a blockchain network node of a blockchain network node and from a client device. The web service request is stored in the blockchain 
network node. The blockchain network node forwards the web service request to a smart contract deployed in a software container on 
the blockchain network node. The blockchain network node obtains an execution result from the smart contract in response to the web 
service request, and sends the execution result to the client device.
