Blockchain Block Processing via Leader-Follower Parallel Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing block generation method for alliance chains and private chains is inefficient, leading to prolonged transaction processing times and potential congestion in the blockchain, as security verification is divided into multiple layers, resulting in delayed transaction processing.
Innovation Solution
A block processing method where a leader node packages transaction information into a candidate block, broadcasts it, and performs verification and execution, while a follower node verifies and executes the transactions, with both nodes reaching consensus using a distributed consensus algorithm to speed up block generation and transaction processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple layers of security verification are performed for alliance chains and private chains, then security is improved, but block generation time is prolonged
Solution Approach 1:
The patent divides the verification process into two distinct phases: pre-check verification (performed by the leader node before block generation) and post-check verification (performed by follower nodes after block generation). This segmentation allows different verification tasks to be performed at different times by different nodes, reducing the time required for block generation while maintaining comprehensive security verification across multiple layers.
Solution Approach 2:
The leader node performs pre-check verification on transactions before packaging them into a candidate block. This preliminary action completes the verification work in advance, so that when the block is generated and broadcast to follower nodes, the verification results are already available, thereby reducing the overall time required for block generation and preventing transaction accumulation.
2Device complexity
If sequential verification and execution is performed by a single node, then process simplicity is maintained, but transaction processing speed is reduced
Solution Approach 1:
The patent merges the verification and execution functions across multiple nodes (leader node and follower nodes) to work together in a coordinated manner. The leader node packages transactions into candidate blocks and performs pre-check verification, while follower nodes perform post-check verification and execution. This merging of functions across multiple nodes increases transaction processing speed while maintaining manageable process simplicity through clear role division.
Solution Approach 2:
The patent introduces a dimensional change from single-node sequential processing to multi-node parallel processing. By distributing verification and execution tasks across leader and follower nodes, the system leverages parallel computation to significantly increase transaction processing speed. The consensus mechanism ensures that all nodes agree on the verification results, maintaining system consistency while achieving high throughput.
3Stability of the object's composition
If all nodes perform verification and execution sequentially, then consistency is ensured, but block generation speed is reduced
Solution Approach 1:
The patent segments the verification and execution process into pre-check (leader node) and post-check (follower nodes) phases. This segmentation allows parallel processing while maintaining consistency through the consensus mechanism. The leader node performs verification and packaging first, then follower nodes verify and execute in parallel, with all nodes reaching consensus on the final results to ensure system consistency.
Solution Approach 2:
The patent ensures continuity of useful action by having the leader node continuously package transactions into candidate blocks and broadcast them to follower nodes. Follower nodes continuously perform verification and execution in parallel. This continuous operation without idle waiting significantly improves block generation speed while the consensus mechanism ensures all nodes remain consistent with each other throughout the process.
