Solution Overview

Problem

Existing centralized methods for blockchain member management are inefficient and lack flexibility, as they rely on a centralized authority for user verification and registration, which can lead to security risks and slow processing performance.

Innovation Solution

Implementing a decentralized blockchain member management system that uses a contract rule agreed upon by members to automatically verify user registration based on signature certificates from certification authorities, allowing users to self-manage their membership without relying on a centralized authority.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If centralized management is used for blockchain member registration, then security control is improved, but processing speed and efficiency deteriorate

Engineering Contradiction:

Improvesecurity controlVSAvoidprocessing speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent extracts the verification function from the centralized management center and implements it directly in smart contracts on the blockchain. The contract automatically verifies user credentials and registration information without requiring manual intervention from the management center, thereby maintaining security control while significantly improving processing speed.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent enables self-service registration where users can independently complete the registration process by submitting their credentials to the blockchain smart contract. The contract autonomously performs verification and registration without requiring users to interact with the centralized management center, thus improving efficiency while maintaining security through cryptographic verification.

Inventive Principle:

Principle #25Self-service

2Reliability

If centralized verification is implemented for user registration, then authentication reliability is improved, but system complexity increases

Engineering Contradiction:

Improveauthentication reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical verification process (manual review by management center staff) with cryptographic verification implemented in smart contracts. The contract uses digital signatures and public-key cryptography to automatically verify user credentials, maintaining authentication reliability while reducing system complexity by eliminating manual processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces smart contracts as an intermediary between users and the blockchain network. The contract serves as an automated mediator that verifies credentials and manages registration, replacing the need for a complex centralized management system while maintaining authentication reliability through cryptographic methods.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If manual verification processes are used for member registration, then verification thoroughness is improved, but processing time increases

Engineering Contradiction:

Improveverification thoroughnessVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent requires users to prepare their credentials and verification materials in advance, obtaining digital signatures from authorized entities before attempting registration. The smart contract then performs automated verification of these pre-prepared credentials, ensuring thorough verification while minimizing processing time during the actual registration transaction.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual verification processes with automated cryptographic verification in smart contracts. The contract thoroughly verifies digital signatures, credential validity, and registration requirements automatically, maintaining verification thoroughness while reducing processing time from minutes or hours to seconds.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Implementations of the present specification disclose blockchain member management data processing. In an implementation, a contract rule is stored, where the contract rule includes a rule that is agreed upon by blockchain members and is used for determining whether a registering user can join a blockchain. A registration transaction message is received from the registering user based on the contract rule, where the registration transaction message includes identification information of a plurality K of certification authorities and signature certificates of the plurality K of certification authorities. Verification of the signature certificates is performed based on the identification information by using public keys of the plurality K of certification authorities in a blockchain node. A determination is performed that the registering user becomes a new blockchain member in response to determining that verification on the signature certificates of the plurality K of certification authorities succeeds.
