Solution Overview

Problem

Conventional blockchain systems face inefficiencies in processing and storage demands, lack scalability, flexibility, and are susceptible to security vulnerabilities, limiting their ability to serve a global user base and manage diverse digital transactions securely.

Innovation Solution

A scalable, secure, and adaptable distributed digital ledger transaction network utilizing a Byzantine-fault-tolerant consensus protocol, a new programming language with linear data types and static-dynamic reference safety analysis, and features like flexible storage management, re-encrypted sub-addresses, and configurable smart contracts to enhance transaction execution and synchronization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional blockchain systems maintain duplicate databases across replicated servers, then security and decentralization are improved, but processing and storage demands on validator nodes increase significantly

Engineering Contradiction:

ImprovesecurityVSAvoidstorage demands

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts the full duplicate database from each validator node and replaces it with only the necessary authentication keys and account information. This extraction principle reduces storage demands while maintaining security through cryptographic verification rather than full data replication.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Each validator node maintains only the locally necessary data (authentication keys and account info) rather than full duplicate databases. This local quality approach allows nodes to have different data characteristics optimized for their validation function, reducing overall storage requirements while maintaining security.

Inventive Principle:

Principle #3Local quality

2Manufacturing precision

If conventional blockchain systems sequentially analyze transactions across validator nodes, then consensus accuracy is improved, but transaction throughput and processing speed deteriorate

Engineering Contradiction:

Improveconsensus accuracyVSAvoidtransaction throughput

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent performs preliminary validation of transactions against authentication keys and account information before full consensus processing. This preliminary action filters and prepares transactions in advance, enabling faster throughput while maintaining consensus accuracy through pre-verified data.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If conventional blockchain systems provide unrestricted digital asset access to user accounts, then ease of operation is improved, but security against malicious attacks deteriorates

Engineering Contradiction:

Improveasset accessibilityVSAvoidsecurity vulnerabilities

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent implements preliminary security measures by storing authentication keys and account information in a secure, distributed manner before any asset access attempts. This preliminary anti-action prevents malicious attacks by having security controls already in place, allowing unrestricted legitimate access while blocking harmful actions.

Inventive Principle:

Principle #9Preliminary anti-action

4Reliability

If conventional blockchain systems perform reference safety analysis on source code at machine code level, then security checking is improved, but accuracy in identifying reference safety issues deteriorates

Engineering Contradiction:

Improvesecurity checkingVSAvoidaccuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The patent changes the dimension of analysis from machine code level to a higher-level authentication key and account information verification. This dimensional shift enables more accurate identification of reference safety issues by analyzing code at the appropriate abstraction level where such issues are more apparent and verifiable.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
