Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a third-party intermediary is used to transfer data between different blockchains, then data transfer can be achieved, but security concerns arise due to credit issues with the intermediary
Solution Approach 1:
The patent extracts and removes the third-party intermediary from the cross-blockchain data transfer process. By using direct cryptographic verification between blockchain nodes, the intermediary component is completely eliminated, allowing data transfer without relying on external trusted parties.
Solution Approach 2:
The blockchain system performs self-verification through cryptographic signatures and consensus mechanisms. Each blockchain node independently verifies the authenticity and validity of cross-chain data using predefined verification rules, eliminating the need for external intermediary services.
2Productivity
If a third-party intermediary is used for cross-blockchain asset transfer, then asset transfer can be performed, but efficiency is reduced due to the intermediary involvement
Solution Approach 1:
The intermediary component is extracted from the asset transfer process. The patent enables direct asset transfer between blockchains by removing the intermediary step, allowing transactions to be processed directly between source and destination blockchains without external coordination delays.
Solution Approach 2:
The patent establishes predetermined verification rules and cryptographic key pairs before cross-chain asset transfer. These preliminary arrangements include pre-configured verification contracts and shared secret keys, enabling rapid verification and transfer execution without time-consuming intermediary coordination during the actual transfer.
3Productivity
If direct asset transfer between blockchains is implemented without intermediaries, then efficiency is improved, but verification complexity increases
Solution Approach 1:
The patent introduces cryptographic verification mechanisms and consensus protocols as automated mediators between blockchains. These verification systems use predefined rules, digital signatures, and smart contracts to automatically validate cross-chain transactions, managing verification complexity through standardized cryptographic protocols rather than manual processes.
Solution Approach 2:
The verification mechanism is designed as a universal system that handles multiple types of cross-chain operations (data transfer, asset transfer, verification) through a single standardized cryptographic framework. This multi-functional verification approach reduces overall complexity by providing a unified verification method rather than separate complex procedures for each operation type.

AI summary
A cross-blockchain data processing method is provided. The method includes: obtaining an asset transfer instruction triggered for a first asset on the first blockchain, and configuring an asset state of the first asset to a locked state on the first blockchain; determining the first asset in the locked state as an asset, and determining a cross-chain asset transfer request corresponding to the asset; obtaining an asset transfer interface associated with a second blockchain, and calling the asset transfer interface to transmit the cross-chain asset transfer request to a second server node on the second blockchain; and receiving signing response information transmitted by the second server node in response to determining that the verification succeeds, freezing the asset on the first blockchain according to the signing response information, and notifying the second server node to release a second asset associated with the asset on the second blockchain.
