Solution Overview

Problem

Existing distributed ledger consensus algorithms, such as proof-of-work and proof-of-stake, are susceptible to dominance by entities with significant resources, leading to inefficiencies and security vulnerabilities.

Innovation Solution

A distributed ledger system where nodes are invited and registered through a blockchain-based process, with a trusted node system ensuring that only invited and verified nodes can participate in voting to accept changes to the ledger, thereby preventing single-entity control and enhancing security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If proof-of-work consensus algorithm is used, then security is improved, but computing power waste increases

Engineering Contradiction:
ImprovesecurityVSAvoidcomputing power waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts the security function from the resource-intensive proof-of-work mechanism by implementing a separate voting system where pre-qualified nodes vote on ledger changes. This separates the security verification function from the computationally expensive puzzle-solving process, maintaining security while eliminating the waste of computing power on unsuccessful attempts.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary layer of pre-qualified voting nodes that act as mediators between the ledger changes and the consensus process. These voting nodes are vetted through the invitation and test process, creating an intermediary trust layer that eliminates the need for proof-of-work's brute-force security approach.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of energy

If proof-of-stake consensus algorithm is used, then computing power waste is reduced, but susceptibility to entity dominance increases

Engineering Contradiction:
Improvecomputing power wasteVSAvoidsusceptibility to entity dominance
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent segments the voting node population through multiple layers: genesis nodes, invited nodes, and nodes that pass tests. This segmentation prevents any single entity from easily dominating the network by controlling a large portion of voting nodes, as each segment requires different qualification criteria and the overall distribution is controlled through the invitation mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary actions by requiring nodes to pass invitations and tests before becoming voting nodes. This pre-qualification process ensures that voting nodes are trustworthy and distributed in a way that prevents later dominance by any single entity, addressing the vulnerability before it can manifest.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If majority-supported consensus algorithm is used, then simplicity is improved, but susceptibility to entity dominance increases

Engineering Contradiction:
ImprovesimplicityVSAvoidsusceptibility to entity dominance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies preliminary action by establishing a pre-qualified voting node population through invitations and tests before the consensus process begins. This pre-screening maintains the simplicity of majority-based voting while preventing entity dominance, as the voting nodes are already vetted and distributed in a controlled manner.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If invitation and test process is implemented, then security is improved, but device complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the node population into distinct categories (genesis nodes, invited nodes, voting nodes) with clear transition criteria. This segmentation organizes the complexity into manageable stages, making the invitation and test process more tractable while maintaining security through progressive qualification.

Inventive Principle:
Principle #1Segmentation
