Photonic processor with multiple layers of feedback for digital currency transactions

A non-transitory computer-readable storage medium comprising stored instructions that, when executed by at least one processor, cause the at least one processor to:

• instruct one or more photonic input circuits of a photonic processor to generate one or more photonic output values based on one or more photonic input signals;
• instruct at least one first photonic adder of a first set of one or more photonic adders of the photonic processor to:
• receive a first feedback signal from a first carry output of the at least one first photonic adder, and
• generate a photonic sum of one or more photonic sums, based at least in part on a portion of the one or more photonic output values and the first feedback signal;
• and
• instruct at least one second photonic adder of a second set of one or more photonic adders of the photonic processor to:
• receive a second feedback signal from a second carry output of the at least one second photonic adder, and
• generate an updated version of a photonic input signal of the one or more photonic input signals, based at least in part on a portion of the one or more photonic sums and the second feedback signal.

A method comprising:

• generating, by one or more photonic input circuits of a photonic processor, one or more photonic output values based on one or more photonic input signals;
• receiving, by at least one first photonic adder of a first set of one or more photonic adders of the photonic processor, a first feedback signal from a first carry output of the at least one first photonic adder;
• generating, by the at least one first photonic adder, a photonic sum of one or more photonic sums, based at least in part on a portion of the one or more photonic output values and the first feedback signal;
• receiving, by at least one second photonic adder of a second set of one or more photonic adders of the photonic processor, a second feedback signal from a second carry output of the at least one second photonic adder;
• and
• generating, by the at least one second photonic adder, an updated version of a photonic input signal of the one or more photonic input signals, based at least in part on a portion of the one or more photonic sums and the second feedback signal.
