Abstract: A blockchain-based method for saving research data is implemented by a processing system. The processing system is connected to a blockchain system, and stores a user account associated with the blockchain system. The method includes sending a deployment request that includes the user account and an application to the blockchain system, in order for the blockchain system to deploy the application associated with the user account on the blockchain system. The method further includes generating and sending a processing request that includes a to-be-processed dataset to the blockchain system, in order for the blockchain system to analyze the to-be-processed dataset using the application so as to obtain a target dataset that corresponds to the to-be-processed dataset and that indicates an analysis result of the to-be-processed dataset, to store the to-be-processed dataset and the target dataset in the blockchain system, and to send the target dataset to the processing system.
