This invention discloses a digital instruction release control method, chip, and system based on physical disturbance characteristics and device-intrinsic fingerprints. The method acquires real-time physical state information related to the execution object, execution environment, or execution node corresponding to the digital instruction to be verified; acquires the device-intrinsic fingerprint parameters or their derived response values ​​of the execution node; and acquires the digital feature information of the digital instruction to be verified.
