Solution Overview

Problem

Current blockchain consensus processing methods require significant bandwidth for transmitting complete transaction data, which can lead to inefficiencies and potential selective consensus issues, where the primary node may unfairly influence transactions.

Innovation Solution

Implementing an erasure code algorithm to fragment transaction data into distinct fragments, allowing only these fragments to be transmitted between nodes, enabling efficient consensus processing while maintaining data integrity and fairness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complete transaction data is transmitted between nodes in traditional blockchain consensus processing, then data integrity is maintained, but bandwidth consumption increases significantly

Engineering Contradiction:

Improvedata integrityVSAvoidbandwidth consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent divides complete transaction data into multiple data fragments using erasure code technology. Each node receives and processes only its assigned fragment rather than the complete dataset, significantly reducing bandwidth consumption while maintaining the ability to reconstruct the original data through erasure code recovery mechanisms.

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If the primary node transmits complete transaction data to all nodes, then consensus accuracy is ensured, but processing time increases

Engineering Contradiction:

Improveconsensus accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

By segmenting transaction data into fragments and distributing them to different nodes simultaneously, the system enables parallel processing of consensus operations. Nodes can independently verify their assigned fragments and contribute to the overall consensus process, reducing total processing time while maintaining consensus accuracy through coordinated verification.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary fragmentation and distribution of transaction data before the consensus process begins. This preliminary action allows nodes to have their verification data ready in advance, eliminating the need to wait for complete data transmission before starting consensus operations, thus reducing processing time without compromising accuracy.

Inventive Principle:

Principle #10Preliminary action

3Loss of information

If the primary node transmits complete transaction data, then data completeness is guaranteed, but network load increases

Engineering Contradiction:

Improvedata completenessVSAvoidnetwork load

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The patent segments complete transaction data into multiple fragments and distributes them across the network. Each node receives only its assigned fragment, reducing the amount of data transmitted over the network. The erasure code mechanism ensures that data completeness can be reconstructed from any sufficient subset of fragments, maintaining data completeness while reducing network load.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces erasure code technology as an intermediary mechanism that enables efficient data distribution and reconstruction. This intermediary allows the system to achieve data completeness without requiring all nodes to receive and transmit complete datasets, thereby reducing overall network load while maintaining information integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Productivity

If the primary node selectively transmits specific transactions, then transmission efficiency improves, but fairness deteriorates due to potential malicious behavior

Engineering Contradiction:

Improvetransmission efficiencyVSAvoidconsensus fairness

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments transaction data into fragments and distributes them in a predetermined, transparent manner rather than allowing selective transmission. This segmentation approach maintains transmission efficiency by avoiding the transmission of complete datasets while ensuring fairness through the deterministic and verifiable fragment distribution mechanism, preventing the primary node from exercising selective discretion.

Inventive Principle:

Principle #1Segmentation

AI summary

A method for blockchain-based transaction consensus processing is provided. Node devices in a blockchain include at least one primary node device and several secondary node devices, the primary node device fragments proposed transaction data into a specified number of data fragments based on an erasure code algorithm, and the method includes: receiving a data fragment of the transaction data that is sent by the primary node device in a unicast mode, where respective data fragments sent by the primary node device to individual node devices in a unicast mode are different from one another; broadcasting the received data fragment to other node devices in the blockchain, and receiving data fragments of the transaction data that are broadcast by the other node devices; determining whether the number of received data fragments of the transaction data reaches an erasure code recovery threshold; and if so, performing data recovery on the received data fragments based on an erasure code reconstruction algorithm to obtain original content of the transaction data, to complete consensus processing with respect to the original content of the transaction data.
