Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blockchain systems face challenges with data bloat due to immutability, requiring large storage for historical transactions, and lack efficient mechanisms for data privacy and remote execution in distributed ledger systems, particularly in financial transactions involving cryptocurrencies.
Innovation Solution
The implementation of a decay control mechanism to manage state nodes, a remote execution mechanism for distributed code execution, and a security cryptographic key management system to enhance data privacy and transaction security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Blockchain systems maintain immutability of historical transactions, then transaction integrity is ensured, but storage requirements increase significantly
Solution Approach 1:
The patent extracts only the essential verification elements (hashes and Merkle roots) from the complete transaction data. Instead of storing all historical transaction details, the system stores condensed cryptographic representations that enable integrity verification without requiring full transaction data retention.
Solution Approach 2:
The patent applies different storage strategies to different data elements. Critical integrity verification data (hashes, Merkle roots, block headers) is stored permanently in the immutable ledger, while full transaction details can be stored locally or in distributed storage systems with different retention policies, optimizing both integrity and storage efficiency.
2Reliability
If Blockchain systems store complete historical transaction data, then data integrity is maintained, but network operation efficiency decreases
Solution Approach 1:
The patent uses cryptographic copies (hashes and Merkle roots) to represent complete transaction datasets. These compact cryptographic representations serve as verification copies that are much smaller than the original transaction data, enabling efficient network transmission and verification operations while maintaining data integrity.
3Reliability
If Blockchain systems implement traditional security mechanisms, then basic transaction security is provided, but data privacy and remote execution capabilities are insufficient
Solution Approach 1:
The patent implements a multi-functional security architecture where the cryptographic key management system serves multiple purposes: traditional transaction signing, advanced data privacy protection through controlled key access, and enabling remote execution of smart contracts. This universal system addresses basic security needs while providing extended functionality for privacy and distributed computation.
Solution Approach 2:
The patent introduces cryptographic key management as an intermediary layer between transaction participants and the Blockchain network. This intermediary mechanism enables fine-grained control over data access and facilitates secure remote execution by mediating authentication and authorization without exposing underlying private keys, thereby enhancing both privacy and execution capabilities.
