Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If block expansion is used to improve transaction processing capacity, then the transaction processing capacity is improved, but the distributed feature is impaired

Engineering Contradiction:

Improvetransaction processing capacityVSAvoiddistributed feature

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent divides the blockchain system into two parts: on-chain operations for state updates and off-chain channels for transaction processing. This segmentation allows high-speed off-chain transactions while maintaining the integrity and distributed nature of the on-chain blockchain, thus improving transaction capacity without compromising the distributed feature.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces off-chain channels as intermediaries between participants. These channels enable direct peer-to-peer transactions without constantly interacting with the main blockchain, reducing the burden on the distributed network while maintaining security through cryptographic commitments that are periodically settled on-chain.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If consensus algorithm improvement is used to improve transaction processing capacity, then the transaction processing capacity is improved, but the impact on performance improvement is limited

Engineering Contradiction:

Improvetransaction processing capacityVSAvoidperformance improvement impact

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent extracts the transaction processing function from the consensus mechanism by moving it to off-chain channels. This allows the consensus algorithm to focus only on periodic state settlement, dramatically improving transaction capacity without being constrained by consensus performance limitations.

Inventive Principle:

Principle #2Taking out (Extraction)

3Productivity

If architecture innovation is used to improve transaction processing capacity, then the transaction processing capacity is improved, but the technical difficulty and complexity increase and compatibility with existing blockchain architecture is reduced

Engineering Contradiction:

Improvetransaction processing capacityVSAvoidtechnical difficulty and complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent designs off-chain channels with universal protocols that can be integrated into existing blockchain architectures. The channel protocol handles multiple functions including transaction processing, state management, and dispute resolution, making it adaptable to different blockchain platforms without requiring fundamental architectural changes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Productivity

If off-chain channel transactions are used to improve transaction processing capacity, then the transaction processing capacity is improved, but transaction security may be compromised

Engineering Contradiction:

Improvetransaction processing capacityVSAvoidtransaction security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements preliminary actions by requiring participants to deposit funds and establish cryptographic commitments before engaging in off-chain transactions. These preliminary measures ensure that even if transactions occur off-chain, security is maintained through pre-established safeguards and the ability to recover funds if disputes arise.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent incorporates feedback mechanisms where transaction states are periodically committed to the on-chain blockchain. This feedback loop ensures that off-chain transactions remain accountable to the main blockchain, providing continuous security verification without reducing transaction speed.

Inventive Principle:

Principle #23Feedback

AI summary

Embodiments of this application provide a blockchain-based data processing method, a device, and a medium. The method includes: sending a first channel closing message on a chain-off channel; receiving a second signature in a second state and a second channel closing message that are sent on the off-chain channel, where the second signature is obtained by signing the second channel closing message; and signing a third channel closing message to obtain a first signature in the second state, and sending the first signature. This application can ensure transaction security and improve a transaction processing capability.
