Cross-Chain Resource Transfer via Lock-and-Release Certificates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cross-chain resource transfer between different blockchains relies on a third-party intermediary, leading to inefficiencies and security risks due to direct interaction with virtual resources.
Innovation Solution
A method and apparatus for cross-chain resource transfer that involves a first service node acquiring a cross-chain resource transfer request, instructing a second service node to lock a virtual resource, performing resource transfer-out processing, and transferring the resource to a designated address within the same blockchain, thereby eliminating the need for a third-party intermediary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a third-party intermediary is used for cross-chain resource transfer, then resource transfer between different blockchains can be achieved, but resource transfer efficiency is low and security risks increase
Solution Approach 1:
The patent extracts and removes the third-party intermediary from the cross-chain resource transfer process. By using direct blockchain-to-blockchain communication protocols and smart contract-based verification, the system eliminates the intermediary node that was causing efficiency losses and security risks, while maintaining the core functionality of cross-chain resource transfer through decentralized peer-to-peer interaction.
Solution Approach 2:
The patent enables blockchains to perform self-service in cross-chain resource transfer by implementing autonomous verification mechanisms. Each blockchain independently verifies the authenticity and validity of transfer requests through cryptographic proofs and consensus protocols, eliminating reliance on external intermediaries and improving both efficiency and security through self-managed validation.
2Adaptability or versatility
If a third-party intermediary is used for cross-chain resource transfer, then resource transfer between different blockchains can be achieved, but security risks increase due to direct contact with virtual resources
Solution Approach 1:
The patent removes the third-party intermediary from the resource transfer path, eliminating the security vulnerability where intermediaries could directly contact and potentially steal virtual resources. The system replaces this with a trustless cryptographic verification mechanism where resources are transferred directly between blockchains through validated transactions, ensuring security without intermediary involvement.
Solution Approach 2:
The patent introduces a cryptographic proof mechanism as a virtual intermediary that mediates cross-chain resource transfer without having direct access to resources. This mediator uses cryptographic signatures and verification protocols to ensure the authenticity and validity of transfer requests, providing security guarantees while maintaining the decentralized nature of the system and preventing resource theft.
3Adaptability or versatility
If a third-party intermediary is used for cross-chain resource transfer, then resource transfer between different blockchains can be achieved, but the complexity of the transfer process increases
Solution Approach 1:
The patent extracts and eliminates the complex operational procedures associated with third-party intermediary management, including resource handover protocols, intermediary state tracking, and multi-step verification processes. By implementing direct blockchain-to-blockchain communication with streamlined cryptographic verification, the system reduces process complexity while maintaining cross-chain transfer functionality.

AI summary
A processing method includes acquiring, by a first service node of a first blockchain, a cross-chain transfer request, the cross-chain transfer request including a virtual resource value, a first resource transfer-out address on the first blockchain, and a first resource transfer-in address on a second blockchain. The cross-chain transfer request is used by a second service node of the second blockchain to lock a first virtual resource of the virtual resource value in the second blockchain. The method further includes performing resource transfer-out processing on a second virtual resource associated with the virtual resource value in the first resource transfer-out address in response to a determination that the second service node locked the first virtual resource successfully. The method further includes transferring the first virtual resource to the first resource transfer-in address in the second blockchain in response to a determination that the second virtual resource was transferred out.
