Solution Overview

Problem

Existing proof of work (PoW) algorithms in blockchain systems are computationally wasteful, leading to excessive energy consumption and resource drain, while alternative consensus algorithms like Proof of Stake (PoS) are difficult to implement in widely adopted systems.

Innovation Solution

Implement a 'proof of useful randomness' (PoUR) algorithm that generates pre-computed algebraic commitments during PoW, which can be used in future cryptographic tasks, reducing unnecessary computations and preserving the classical PoW architecture.

Engineering Contradictions & Design Principles

1Reliability

If traditional PoW algorithms are used to ensure security and consensus, then security and consensus are improved, but energy consumption and computational waste increase significantly

Engineering Contradiction:

ImprovesecurityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent converts the previously wasteful random number generation during PoW into a beneficial resource by capturing and storing the generated randomness for future cryptographic operations. The randomness that would have been discarded is now reused for digital signatures, key exchange, and other crypto tasks, transforming energy waste into useful computational output.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The system performs preliminary generation and storage of cryptographic commitments and random numbers during the PoW process. These pre-computed values are stored and can be reused in subsequent cryptographic operations, eliminating the need to perform expensive computations again and reducing future energy consumption.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If brute force hashing operations are performed to achieve proof of work, then consensus and security are ensured, but computational resources and time are wasted on unsuccessful attempts

Engineering Contradiction:

ImproveconsensusVSAvoidcomputational time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent transforms the time-consuming brute force hashing into a useful process by capturing the random numbers generated during these operations. Even though most hashing attempts fail, the random numbers they generate are stored and reused for cryptographic operations, converting computational time waste into valuable cryptographic material.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

Instead of discarding the random numbers generated during PoW hashing operations, the system recovers and stores them for future use. This recovery mechanism allows the system to reuse computational results that would otherwise be wasted, reducing the need for repeated computations.

Inventive Principle:

Principle #34Discarding and recovering

3Use of energy by moving object

If Proof of Stake algorithm is implemented to reduce energy consumption, then energy efficiency is improved, but implementation complexity and system compatibility decrease

Engineering Contradiction:

Core Design Contradiction:

Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent creates a universal solution that works within existing PoW blockchain systems while providing the energy efficiency benefits of reused computations. The randomness capture and storage mechanism can be integrated into current PoW systems without requiring a complete algorithm change, making it universally applicable to existing blockchains.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system introduces an intermediary layer of randomness capture and storage between the PoW hashing process and subsequent cryptographic operations. This intermediary mechanism enables efficient reuse of computational results without fundamentally changing the PoW consensus algorithm, thus avoiding implementation complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)
