Solution Overview

Problem

Existing blockchain platforms lack effective identity management, leading to issues such as Sybil attacks and the inability to securely link blockchain accounts to real users, particularly across multiple private and permissioned networks within an organization.

Innovation Solution

A method for generating enhanced hierarchical deterministic wallets with identity registration and certification, allowing for the derivation of enhanced and toughened parent and child public and private keys, which can be exported to specific blockchain networks while maintaining user identity verification across networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional hierarchical deterministic wallets are used for key management across multiple blockchain networks, then key generation and management becomes simplified, but security against Sybil attacks and identity linkage across networks deteriorates

Engineering Contradiction:

Improvekey managementVSAvoididentity verification

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent segments the traditional HD wallet structure into enhanced components with separate identity verification layers. It introduces distinct parent and child key relationships with embedded identity proofs, separating key generation from identity management while maintaining their cryptographic linkage. This segmentation allows independent verification of identity across networks without compromising key management efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces certification authorities and identity verification intermediaries that mediate between the HD wallet structure and blockchain networks. These intermediaries verify and certify the linkage between derived keys and real-user identities, providing a trusted bridge that enhances reliability without complicating the underlying key management operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If private blockchain networks are used within organizations, then control and security over transactions is improved, but ability to link accounts across different networks deteriorates

Engineering Contradiction:

Improvetransaction controlVSAvoidcross-network identity linkage

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal identity verification framework that functions across multiple private blockchain networks. The enhanced HD wallet structure with embedded identity proofs and certification mechanisms can operate on any private or permissioned network, providing consistent cross-network identity linkage while maintaining each network's control and security requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent modifies the traditional wallet parameters by incorporating identity verification data and certification tokens into the key derivation process. These parameter changes enable the same wallet structure to adapt to different private network environments while maintaining verified identity linkages across networks through adjustable certification parameters.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If multiple Externally Owned Accounts are created for different blockchain networks, then network-specific functionality is improved, but risk of key loss and mass theft of private keys increases

Engineering Contradiction:

Improvenetwork-specific functionalityVSAvoidkey loss and theft risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements a nested hierarchical structure where parent keys contain embedded identity verification data, and child keys are nested within this verified framework. This nesting allows multiple network-specific accounts to be derived from a single verified parent structure, reducing the number of independent private keys that need to be managed and thereby reducing overall key loss and theft risk.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent performs preliminary identity verification and certification at the parent key level before deriving child keys for specific networks. This preliminary action ensures that all subsequent key derivations inherit verified identity linkage, eliminating the need for separate verification processes for each network-specific account and reducing exposure to key theft risks across multiple accounts.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method for qualifying a validator server used in zero-knowledge transactions including receiving hashed transactions between a prover client and a verifier server from the prover client and hashed transactions between the prover client and the verifier server, accessing the hashed transactions an enforcement node, analyzing the first and second pluralities of hashed transactions by the enforcement node, and qualifying or disqualifying the verifier server by the enforcement node responsive to analyzing the first and second pluralities of hashed transactions.
