Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transfer is performed in traditional storage systems, then data movement between locations is achieved, but data integrity and traceability are compromised
Solution Approach 1:
The patent introduces blockchain as an intermediary system between data storage and transfer operations. The blockchain network acts as a neutral mediator that records and validates all data transfer transactions, providing trustless verification of data integrity and provenance without requiring complex point-to-point verification protocols between participating entities.
Solution Approach 2:
The patent creates cryptographic copies of data provenance information by generating Merkle roots and storing them on the blockchain. These cryptographic copies serve as immutable records that can be verified without accessing the original data, enabling efficient integrity verification while maintaining data privacy and reducing storage requirements.
2Reliability
If blockchain technology is integrated for data transfer validation, then data integrity and traceability are improved, but system complexity increases
Solution Approach 1:
The patent segments the data verification process into distinct cryptographic components: generating Merkle roots from data metadata, creating cryptographic proofs, and storing verification data on the blockchain. This segmentation allows each component to be independently optimized and verified, reducing overall system complexity despite the enhanced traceability capabilities.
Solution Approach 2:
The patent implements a universal blockchain-based verification system that can handle multiple types of data transfer operations (storage, retrieval, modification, deletion) through a single standardized protocol. The Merkle root-based verification mechanism provides multi-functional capability across different data operations, reducing the need for separate verification systems for each operation type.
3Reliability
If traditional data transfer methods are used, then transfer speed is maintained, but data corruption or loss may occur
Solution Approach 1:
The patent performs preliminary cryptographic processing by generating Merkle roots and storing them on the blockchain before actual data transfer operations. This preliminary action creates pre-configured verification mechanisms that enable rapid validation during data transfer, reducing the time required for integrity verification while maintaining strong data protection.
Solution Approach 2:
The patent replaces traditional mechanical verification methods (such as checksums and hash comparisons) with cryptographic proof-based validation using Merkle trees and blockchain verification. This substitution enables parallel verification of multiple data elements simultaneously, reducing validation time while enhancing data protection capabilities.

AI summary
Embodiments of the present disclosure relate to a method, an apparatus, an electronic device, and a medium for data transfer. The method includes generating, based on metadata of to-be-transferred data and a blockchain including a data transfer record, an ownership certificate of an initiator of a transfer for the to-be-transferred data. The method further includes generating a new transfer record for validation by a blockchain system, where the new transfer record includes the ownership certificate and validation information associated with a receiver of the transfer. The method further includes transferring the to-be-transferred data to the receiver in response to that the new transfer record passes validation of the blockchain system. In this way, the data transfer record may be reliably stored in the blockchain, thereby providing reliable integrity protection and data traceability for a storage system.
