Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As blockchain capacity increases for data storage, efficiently accessing and retrieving relevant information becomes challenging, and existing methods like Meta net, bitDB, and B:// bitcoin data protocol are inadequate for navigating and retrieving data efficiently.
Innovation Solution
A request-response protocol is implemented for accessing data from a blockchain, utilizing encryption and decryption mechanisms with shared secrets, and a method for navigating hyperlinks to destination transactions, enabling efficient data retrieval and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If blockchain capacity is increased for data storage, then data storage capability is improved, but data retrieval efficiency deteriorates
Solution Approach 1:
The patent segments the blockchain data structure into distinct components: headers containing metadata (transaction IDs, timestamps, merkle roots) and body sections containing actual transaction data. This segmentation allows selective retrieval of header information for navigation and filtering without requiring access to the entire blockchain, thereby improving retrieval efficiency while maintaining storage capacity.
Solution Approach 2:
The patent introduces an intermediary indexing system that creates a separate data structure mapping transaction identifiers to their locations in the blockchain. This intermediary layer enables rapid lookup and navigation to specific transactions without scanning through the entire blockchain, resolving the contradiction between storing large quantities of data and retrieving them efficiently.
2Reliability
If encryption mechanisms are implemented for secure data access, then security is improved, but data access complexity increases
Solution Approach 1:
The patent implements preliminary encryption of data at the time of transaction creation, with encryption keys and access policies pre-configured in the transaction metadata. This preliminary action ensures security is built-in from the start rather than added later, and the pre-configured access rules automatically manage the complexity of key distribution and access control without requiring complex runtime decision-making.
