Abstract
An electronic system includes a plurality of hardware devices and an authenticated circuit. The authenticated circuit is integrated, as fixed hardware, in the electronic system together with the plurality of hardware devices during a manufacturing process of the electronic system, the authenticated circuit configured to verify system integrity based on a system identification code provided from inside of the electronic system by at least one of the plurality of hardware devices, the system integrity indicating that a combination of the authenticated circuit and the plurality of hardware devices has not been modified since the manufacturing process, the authenticated circuit configured to perform a mining operation to generate a next block, the next block to be linked to a blockchain only in response to the authenticated circuit verifying the system integrity. Indiscriminate mining competition may be prevented or reduced in likelihood of occurrence.
