Solution Overview

Problem

Existing cryptocurrency systems face challenges in compliance with regulatory frameworks due to their distributed nature, leading to inefficiencies, counterparty risk, and difficulties in simultaneous transaction settlement, while traditional payment systems like ACH transfers and wire transfers pose structural problems for digital asset transactions.

Innovation Solution

A bank-issued electronic negotiable instrument, Avit, is implemented via a smart contract on a blockchain, allowing for compliance with regulations and enabling simultaneous settlement of transactions through a cryptographic token system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a distributed consensus network is used for cryptocurrency circulation, then security and reliability are improved, but regulatory compliance and transaction control become difficult

Engineering Contradiction:
Improvetransaction securityVSAvoidregulatory compliance
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the circulation system into multiple independent circulation groups (first circulation group and second circulation group) with different regulatory regimes. Each group operates under its own smart contract rules, allowing simultaneous compliance with different regulatory frameworks while maintaining the security benefits of the distributed consensus network.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a bank as an intermediary that issues the cryptographic tokens and manages the circulation groups. The bank acts as a trusted intermediary that ensures regulatory compliance while the underlying blockchain technology maintains transaction security and immutability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional payment systems like ACH transfers are used, then regulatory compliance is improved, but settlement speed and efficiency deteriorate

Engineering Contradiction:
Improveregulatory complianceVSAvoidsettlement speed
Core Design Contradiction:
Adaptability or versatilityVSSpeed

Solution Approach 1:

The patent replaces the mechanical, multi-day settlement process of traditional ACH transfers with a cryptographic token system that leverages blockchain technology. The smart contracts automate settlement processes, enabling near-real-time finality while maintaining regulatory compliance through programmable rules and bank oversight.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If wire transfers are used for digital asset transactions, then security is improved, but transaction speed and cost efficiency deteriorate

Engineering Contradiction:
Improvetransaction securityVSAvoidtransaction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent creates a universal cryptographic token system that can serve multiple functions: it provides the security of bank-issued instruments, the speed of digital asset transactions, and compliance with regulatory frameworks. The same token infrastructure supports both secured transactions and general circulation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes key parameters of the transaction system by using cryptographic tokens with programmable smart contracts that enable faster settlement finality compared to traditional wire transfers, while maintaining security through bank issuance and regulatory-compliant circulation group structures.

Inventive Principle:
Principle #35Parameter changes

4Ease of operation

If cryptographic tokens are issued without circulation group restrictions, then liquidity and ease of transfer are improved, but regulatory control and compliance monitoring deteriorate

Engineering Contradiction:
Improvetoken transferabilityVSAvoidcompliance management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the token population into different circulation groups with specific transfer rules. The first circulation group allows broader transferability while the second circulation group imposes restrictions, enabling the system to provide both high liquidity where needed and regulatory control where required.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The smart contracts automatically enforce circulation group rules and compliance requirements, eliminating the need for manual compliance monitoring. The system self-manages transfer restrictions and regulatory controls through programmable logic, reducing operational complexity.

Inventive Principle:
Principle #25Self-service

AI summary

A custom cryptographic token and smart contract that is configured to exist in one of two groups and is issued by the same bank or depository institution that also collects corresponding fiat currency deposits. The two groups are a circulation group and a non-circulation group. The non-circulation group is not associated with any given user, but rather an issuing entity. Custom cryptographic tokens residing in the circulation group are associated with a user and are traded according to smart contract protocol.
