1. A method for reducing energy consumption of cryptographic computations, comprising:
determining at least one desired type of cryptographic commitment;
generating a random value;
transforming the random value into a cryptographic output value;
performing a Blockchain function based upon at least one of the random value and the cryptographic output value;
storing the random value and cryptographic output value as a cryptographic commitment of the desired type; and
providing the cryptographic commitment for subsequent use in a cryptographic operation;
wherein the stored cryptographic commitment is provided to a processor operating a digital signature operation, such that the processor performs the digital signature operation using the stored cryptographic commitment without generating a new random value.
