Solution Overview

Problem

Existing blockchain technologies lack efficient methods for validating tokens that have not been electronically countersigned by an authorized signatory, limiting their versatility and security in applications beyond cryptocurrency.

Innovation Solution

A computer-implemented method and system for validating tokens by inspecting blockchain transactions, following a logical path to establish token validity, and maintaining a title registry database to record token transfers, ensuring authentication by an authorized signatory.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If blockchain technology is used for token validation without authorized signatory countersigning, then versatility and efficiency are improved, but security and reliability deteriorate

Engineering Contradiction:
ImproveversatilityVSAvoidsecurity
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces an intermediary validation mechanism that bridges the gap between decentralized efficiency and centralized security. The system uses a validation service that acts as a mediator between token holders and the blockchain, verifying token authenticity through a combination of on-chain data inspection and off-chain validation logic, thereby maintaining both versatility and security

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements preliminary validation actions by pre-establishing validation rules, authorized signatory lists, and token metadata before transactions occur. The system performs preliminary checks on token validity, ownership history, and authorization status before allowing transfers, ensuring security is built-in rather than added later

Inventive Principle:
Principle #10Preliminary action

2Reliability

If traditional token validation methods are used, then security is maintained, but processing speed and efficiency deteriorate

Engineering Contradiction:
ImprovesecurityVSAvoidprocessing speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments the validation process into distinct modular components: on-chain transaction inspection, off-chain validation logic execution, authorized signatory verification, and token metadata validation. This segmentation allows each component to be optimized independently, improving overall processing speed while maintaining security through comprehensive multi-layer validation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies partial validation actions by selectively validating only the necessary aspects of a transaction based on token type and risk level. High-value or high-risk transactions undergo more extensive validation, while low-risk transactions receive streamlined validation, optimizing processing speed without compromising security where needed

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If comprehensive token validation is performed, then reliability is improved, but device complexity and system complexity deteriorate

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal validation service that handles multiple token types and validation scenarios through a single unified system. The validation service can process various token categories (cryptocurrency, fiat, commodities, securities) using the same core validation architecture, reducing system complexity while maintaining comprehensive authentication reliability across different application domains

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

AI summary

A computer-implemented method of determining the validity of a token (T) associated with a quantity of cryptocurrency is provided. In some embodiments, the method comprises: a second user (B) receiving, over a communications network, a first transaction comprising a transfer of the token (T) from a first user (A) to the second user (B), querying a peer-to-peer distributed ledger to determine whether an authenticated transaction associated with the token (T) can be identified, wherein the authenticated transaction comprises a previous transaction associated with the token (T) and wherein the token (T) has been authorised and responsive to identifying an authenticated transaction, determining that the token (T) is valid. In some embodiments, the method comprises: a second user: receiving, over a communications network, a first transaction comprising a transfer of the token from a first user to the second user; querying a title registry database to determine if a second transaction comprising a transfer of the token is recorded in the title registry database; and responsive to determining that the second transaction is recorded in the title registry database, determining that the token is valid.
