Solution Overview

Problem

In non-token blockchain platforms, there is no effective solution for all nodes to reach a consensus on the authenticity and validity of a new object introduced, unlike Bitcoin-oriented blockchain systems that rely on cipher coins.

Innovation Solution

A blockchain-based system architecture with control nodes that verify and sign ownership declarations using zero-knowledge proof protocols or external databases, allowing other nodes to validate and record new objects without relying on cipher coins.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Bitcoin-oriented blockchain systems use cipher coins for verification, then authenticity and validity of new objects can be ensured, but the system becomes dependent on token-based mechanisms which are not applicable to non-token platforms

Engineering Contradiction:

Improveauthenticity and validity verificationVSAvoidapplicability to non-token platforms

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces control nodes as intermediary entities that mediate the verification process between to-be-verified nodes and the blockchain system. These control nodes perform identity verification and digital signing of ownership declarations, replacing the cipher coin mechanism with a trusted intermediary verification approach that works on non-token platforms.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the cryptographic mining mechanism (mechanical system) with a control node verification system. Instead of using computational power and cipher coins to verify transactions, the system uses control nodes with verification capabilities to authenticate ownership declarations and sign them digitally, substituting the mining-based verification mechanism.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If all nodes in a non-token blockchain platform are equal, then decentralization is maintained, but no effective solution exists for verifying authenticity of first-introduced objects

Engineering Contradiction:

Improvedecentralization and node equalityVSAvoidverification of first-introduced objects

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent segments the node population into two functional categories: control nodes with verification and signing capabilities, and to-be-verified nodes that initiate ownership declarations. This segmentation allows the system to maintain decentralization while assigning specific verification responsibilities to control nodes, enabling reliable verification of first-introduced objects without centralizing all power in a single entity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements partial action by having only control nodes perform verification and signing functions, rather than requiring all nodes to have equal verification capabilities. This partial assignment of verification responsibilities enables the system to achieve reliable verification of first-introduced objects while maintaining a decentralized structure, as not all nodes need to perform the same functions.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If zero-knowledge proof protocols are used for verification, then privacy and authenticity are protected, but verification complexity and computational requirements increase

Engineering Contradiction:

Improveprivacy-protected authenticity verificationVSAvoidverification protocol complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses control nodes as intermediaries that handle the complex zero-knowledge proof verification process. Instead of requiring all nodes to implement and execute complex zero-knowledge proof protocols, the control nodes perform the verification and digital signing, simplifying the overall system architecture while maintaining the privacy and authenticity benefits of zero-knowledge proofs.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

There is disclosed a blockchain-based system, and an electronic apparatus and a method in the system. The electronic apparatus at a control node end includes a processor configured to: verify, in response to an ownership declaration for a new object that is first introduced from a to-be-verified node in the system, the ownership declaration; and sign, in a case that the verification is successful, the ownership declaration to be returned to the to-be-verified node, so that the signed ownership declaration is verified by other nodes in the system and a record regarding the ownership declaration is added to the blockchain. According to the embodiment of the disclosure, it is possible to verify the newly introduced object in the blockchain-based system without binding with a cipher coin, while maintaining a peer-to-peer architecture of the blockchain-based system.
