Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing blockchain systems face challenges in implementing data rewriting across multiple chains, particularly in maintaining consistency and accountability, due to the immutability of blockchain data and the lack of a centralized entity to coordinate cross-chain transactions, leading to potential economic losses and inconsistent decentralized application states.

Innovation Solution

A method and system for atomic, consistent, and accountable cross-chain rewriting using an intermediary blockchain with monitor, proposer, and validator nodes to generate and validate redaction proposals based on transaction dependency graphs, ensuring all related transactions are rewritten consistently and accountably across multiple blockchains.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blockchain immutability is maintained, then data integrity and security are improved, but the ability to correct errors and comply with data protection regulations deteriorates

Engineering Contradiction:

Improvedata integrityVSAvoiddata correction capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a cross-chain coordinator as an intermediary component that manages redaction proposals across multiple blockchains. This coordinator enables controlled modification of immutable blockchain data by coordinating redaction operations across correlated blockchains, allowing error correction and GDPR compliance while preserving the fundamental immutability property of blockchain systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary validation and coordination of redaction proposals before executing them on the blockchains. By pre-processing redaction requests, validating them against correlation relationships, and obtaining necessary approvals before actual data modification, the system ensures that immutability is maintained until controlled changes are deliberately made through the established protocol.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If existing single-chain rewriting solutions are used, then data rewriting capability is improved, but consistency across multiple correlated blockchains deteriorates

Engineering Contradiction:

Improvedata rewriting capabilityVSAvoidcross-chain consistency

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The cross-chain coordinator is designed as a universal system that can handle rediction proposals across multiple different blockchain networks simultaneously. It maintains correlation relationships between different blockchains and coordinates redaction operations across them, enabling a single rewriting mechanism to serve multiple correlated chains while ensuring consistency throughout the entire cross-chain ecosystem.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements feedback mechanisms where the cross-chain coordinator monitors the state of all correlated blockchains, validates redaction proposals against current chain states, and adjusts coordination decisions based on the outcomes of rediction operations. This feedback loop ensures that consistency is maintained across all blockchains by continuously monitoring and responding to state changes.

Inventive Principle:

Principle #23Feedback

3Productivity

If cross-chain redaction proposals are generated without coordination, then rewriting speed is improved, but atomicity and consistency of cross-chain operations deteriorates

Engineering Contradiction:

Improverewriting speedVSAvoidatomicity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The cross-chain coordinator performs preliminary validation and planning of rediction operations across all correlated blockchains before execution. It identifies all affected chains, validates the rediction proposal against each chain's state, and prepares a coordinated execution plan. This preliminary action ensures that when rediction is executed, it maintains atomicity across chains without requiring slow sequential processing during the actual rewriting operation.

AI summary

A method and system for atomic, consistent and accountable cross-chain rewriting are provided. The method is applicable for a blockchain network comprising a set of correlative blockchains. The method includes: in response to a user redaction proposal for any of the correlative blockchains, generating a set of correlative redaction proposals that involve all related transactions depending on a target transaction to be redacted by the user redaction proposal, based on a transaction dependency graph representing a dependency relationship of transactions, wherein at least one of the transactions in the transactions is to be redacted by the user redaction proposal; validating the user redaction proposal and the correlative redaction proposals, according to a predefined cross-chain redaction policy; calling the correlative blockchains for executing the validated redaction proposals; and updating the transaction dependency graph in response to execution of the validated redaction proposals.
