Solution Overview

Problem

Cryptocurrencies lack transparency, regulation, and security, making them unsuitable for use by financial institutions, and their value fluctuations pose risks for consumers and merchants.

Innovation Solution

Implementing a private distributed ledger system for financial institutions to manage a digital currency pegged to a fiat currency, ensuring transaction transparency, security, and stability, eliminating the need for proof of work, and providing fraud protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a decentralized computing system is used to facilitate cryptocurrency transactions, then financial autonomy and lack of central authority control are improved, but transaction transparency and fraud protection deteriorate

Engineering Contradiction:
Improvefinancial autonomyVSAvoidtransaction transparency
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a hybrid system where a centralized authority (clearing house or financial institution) acts as an intermediary to validate and monitor transactions, while still utilizing distributed ledger technology. This mediator ensures transaction transparency and fraud protection while maintaining the benefits of decentralized processing for routine operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If anonymity is provided in cryptocurrency transactions, then user privacy is improved, but criminal activity detection and regulation deteriorate

Engineering Contradiction:
Improveuser privacyVSAvoidcriminal activity detection
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent implements differential privacy levels where transaction details are anonymized for public viewing while maintaining identifiable information for authorized parties. Regular transactions enjoy full anonymity, while suspicious or high-value transactions automatically trigger enhanced monitoring and identification requirements.

Inventive Principle:
Principle #3Local quality

3Reliability

If proof of work is used to secure the blockchain, then network security is improved, but energy consumption and transaction speed deteriorate

Engineering Contradiction:
Improvenetwork securityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent transitions from proof of work to proof of authority consensus mechanism, fundamentally changing the security parameter from computational difficulty to institutional credibility. This eliminates the need for energy-intensive mining operations while maintaining security through the reputational capital of participating financial institutions.

Inventive Principle:
Principle #35Parameter changes

4Productivity

If cryptocurrency value is allowed to fluctuate freely, then market dynamics and liquidity are improved, but financial stability and consumer protection deteriorate

Engineering Contradiction:
Improvemarket liquidityVSAvoidfinancial stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent implements a feedback mechanism where the centralized authority monitors cryptocurrency value fluctuations and intervenes when stability thresholds are breached. The system automatically adjusts supply or introduces stabilization measures when volatility exceeds predetermined levels, maintaining both liquidity and stability.

Inventive Principle:
Principle #23Feedback

AI summary

Systems and methods for facilitating a transaction between a first entity and a second entity using a digital currency are described. In some aspects, a computing node participates in a private distributed ledger for a financial institution and stores one or more transaction blocks representing transactions in a digital currency. The digital currency is issued by the financial institution and is fixed with respect to a fiat currency. The computing node is configured to receive a transaction for transferring an amount of digital currency from a first entity to a second entity, generate a new transaction block representing the transaction, transmit the new transaction block to other computing nodes participating in the private distributed ledger, receive an indication of validity of the new transaction block, and insert the new transaction block into the private distributed ledger.
