Node Memory Cache for Faster Access in Bifurcated Blockchains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In blockchain systems, simultaneous mining by multiple miner nodes can lead to blockchain bifurcation, resulting in reduced data access efficiency when querying or verifying transactions.
Innovation Solution
Implement a data processing method and apparatus using a node internal memory that includes acquiring transactions from a first block, invoking data reading contracts to access a write cache mapping table, and executing transactions based on target read data, storing results in a cache before writing to the bifurcated blockchain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple miner nodes simultaneously write blocks into the blockchain database, then the blockchain bifurcation phenomenon occurs, but the data access efficiency is reduced
Solution Approach 1:
The patent pre-loads transaction data from the blockchain database into the node's internal memory before actual query operations occur. This preliminary action stores frequently accessed transaction data in a cache structure, so when blocks are simultaneously written during bifurcation events, the data is already available in memory rather than requiring database access during the critical query phase, thus maintaining fast data access despite blockchain bifurcation
Solution Approach 2:
The patent introduces an intermediate cache layer (internal memory) between the blockchain database and the transaction query operations. This intermediary structure acts as a buffer that decouples the database from direct query access, allowing the system to handle blockchain bifurcation scenarios where multiple blocks are written simultaneously without impacting query performance, as the cache serves as a mediator that provides fast access independent of database write operations
2Reliability
If transaction data is stored in the blockchain database, then the data is persistent and reliable, but the data access efficiency is reduced due to database access overhead
Solution Approach 1:
The patent creates copies of transaction data from the blockchain database and stores them in the node's internal memory cache. These copies maintain data integrity and consistency with the original database records while providing significantly faster access speeds. The copy mechanism allows the system to preserve data reliability through database persistence while achieving high data access efficiency through in-memory retrieval of cached copies
3Speed
If the node maintains a cache of transaction data, then the data access speed is improved, but the memory consumption increases
Solution Approach 1:
The patent dynamically adjusts cache management parameters such as cache size limits, eviction policies, and data retention durations based on system conditions and access patterns. By changing these parameters, the system optimizes the balance between maintaining sufficient cached data for fast access and managing memory consumption within acceptable limits, allowing flexible adaptation to different operational scenarios
Data Source
AI summary
A data processing method and apparatus based on a node internal memory, a device and a computer readable storage medium are provided. The method includes: acquiring a data reading contract associated with a transaction in a first block from a chain reading cache of the node internal memory; invoking the data reading contract to acquire a write cache mapping table associated with the first block, and determining target read data associated with the transaction based on a first block cache of the first block in the write cache mapping table; and executing the transaction based on the target read data, storing target cached data, corresponding to a result of executing of the transaction, to the first block cache, and writing the first block into a bifurcated blockchain.
