Abstract

A computer-implemented blockchain-based transaction obfuscation method includes: determining a submission time based on a base time and a submission time interval; determining that no actual transaction information is obtained between the base time and the submission time during the submission time interval; generating false transaction information; cryptographically encoding transaction content in the false transaction information; and subsequent to the submission time, submitting the false transaction information to a blockchain to obfuscate a number of actual transactions in the blockchain.
