Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blockchain uses a first hash-function encryption mechanism, then the chaining of blocks is maintained, but the security protection becomes vulnerable to increasing processing power
Solution Approach 1:
The patent changes the encryption parameter by transitioning from a first hash-function encryption mechanism to a second, improved hash-function encryption mechanism. This parameter change updates the cryptographic security level to resist increasing processing power and potential decryption attacks, directly addressing the vulnerability to manipulation while maintaining blockchain integrity.
2Reliability
If data blocks are transformed and re-chained with a different encryption mechanism, then the security is improved, but the computational resources and energy consumption increase
Solution Approach 1:
The patent segments the blockchain transformation process by transforming only the necessary data blocks and their associated metadata rather than reprocessing the entire blockchain. The transformation module selectively converts data blocks from the first encryption mechanism to the second, reducing unnecessary computational overhead while achieving security improvement.
Solution Approach 2:
The patent performs preliminary transformation of data blocks before they need to be re-chained with the improved encryption mechanism. By preparing and transforming blocks in advance using the transformation module, the system reduces peak computational demands and energy consumption during the security upgrade process.
3Reliability
If multiple first data blocks are transformed into a single blockchain data block, then the security upgrade is achieved without repeated mining, but the device complexity increases
Solution Approach 1:
The patent merges multiple first data blocks into a single blockchain data block structure that is compatible with the second encryption mechanism. The transformation module combines the necessary information from multiple source blocks and reconstructs them in a unified format, simplifying the overall transformation process while achieving security enhancement without requiring repeated mining operations.

AI summary
An object of the present application is to provide a device, which is adapted to be connected with a blockchain network. Hereby, the device comprises a receiving module, which is adapted to receive, from the blockchain network, a first blockchain comprising a plurality of first data blocks. In this context, chaining of the first blockchain is based on a first hash-function encryption mechanism. The device further comprises a transformation module, which is adapted to transform at least two first data blocks of the first blockchain into a single blockchain data block. The device further comprises a request module, which is adapted to request, at the blockchain network, chaining of the single blockchain data block with a second blockchain. Hereby, chaining of the second blockchain is based on a second hash-function encryption mechanism different from the first hash-function encryption mechanism. Another object of the present application is to provide a corresponding method, which is executed in a blockchain network.
