Abstract

The disclosure provides systems and methods for an improved Proof of Work (PoW) technique that enforces the creation of cryptographic tokens while solving the PoW puzzle. The systems and methods disclosed herein more efficiently utilize the high computational and energy consumption in attempts to solve PoW puzzles, by combining the computations necessary for several types of cryptographic functions (e.g., public-key cryptographic methods). For example, systems and methods disclosed herein may reuse pre-computed commitments, while still preserving the traditional and accepted PoW protocols.

Claims (32)

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.

2. The method of claim 1 , characterized in that the Blockchain function is a proof of work operation.

3. The method of claim 1 , wherein the Blockchain function is performed with a disclosable value of the random value and the cryptographic output value.

4. The method of claim 1 , wherein the random value is converted into a private cryptographic key that pairs with the cryptographic output value.

5. The method of claim 1 , wherein the random value is used in a hashing function that outputs a private cryptographic value that pairs with the cryptographic output value.

6. The method of claim 1 , wherein the random value is concatenated with a Blockchain string.

7. The method of claim 6 , wherein the concatenated random value with the Blockchain string is used in a hashing function that outputs a private crypto graphic value that pairs with the cryptographic output value.

8. The method of claim 7 , wherein the private cryptographic value is determined based on a predetermined threshold value.

9. The method of claim 6 , wherein the Blockchain string is a string having an arbitrary length.

10. A system comprising:

at least one Blockchain processing node;

at least one memory having stored thereon instructions which, when executed, cause the system to:

i. perform a proof-of-work operation;

ii. generate at least one cryptographic commitment while performing the proof-of-work operation;

iii. store the cryptographic commitment in the at least one memory;

iv. determine if the proof-of-work operation was solved, and if not repeat steps i-iii;

v. provide the cryptographic commitment to at least one cryptographic processing node.

11. The system of claim 10 , wherein the at least one Blockchain processing node comprises processing resources of a company network, and wherein the memory belongs to the company network.

12. The system of claim 10 , wherein the proof-of-work operation comprises a Blockchain challenge.

13. The system of claim 11 , wherein the instructions further cause the system to determine a need of the company network for at least one type of cryptographic commitment, and generate the cryptographic commitment specific to such need.

14. The system of claim 10 , wherein the instructions further cause the system to determine a need of a third party network for at least one type of cryptographic commitment, and generate the cryptographic commitment specific to such need.

15. The system of claim 10 , wherein the proof of work operation is performed based on a random value.

16. The system of claim 15 , wherein the random value is converted into a private cryptographic key.

17. The system of claim 15 , wherein the random value is concatenated with a Blockchain string.

18. The method of claim 17 , wherein the concatenated random value with the Blockchain string is used in a hashing function that outputs a private crypto graphic value.
