Parachain Synchronization via Block Operation Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parachain data synchronization methods lead to inconsistent block information across nodes due to main chain bifurcation, causing synchronization issues and inconsistencies.
Innovation Solution
A method for synchronizing main chain block data using first block operation sequence information, which includes operation serial numbers and operation information, to rapidly update parachain data without inconsistencies, even in cases of bifurcation or other disruptions, by processing transaction information and generating blocks with specific operation sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parachain synchronizes block information with a lag behind main chain height to prevent inconsistency, then reliability is improved, but productivity deteriorates
Solution Approach 1:
The main chain node records operation sequence information (including operation serial numbers and operation information) for each block in advance before the parachain needs to synchronize. This preliminary recording of the complete operation sequence allows the parachain to rapidly synchronize without needing to lag behind main chain height, thus improving both reliability and productivity
Solution Approach 2:
The operation sequence information acts as an intermediary data structure that bridges the main chain and parachain. It contains the complete sequence of block operations with their serial numbers and information, serving as a mediator that enables the parachain to synchronize accurately and rapidly without direct dependency on continuous main chain height progression, thereby resolving the contradiction between consistency and speed
2Ease of operation
If parachain uses traditional block synchronization method, then ease of operation is maintained, but reliability deteriorates due to bifurcation
Solution Approach 1:
The operation sequence information includes operation serial numbers that provide a feedback mechanism for tracking and verifying block operations. This feedback structure enables the parachain to accurately track which blocks have been processed and ensures consistency even during bifurcation events, maintaining both ease of operation and reliability
Solution Approach 2:
The main chain node preliminarily records and transmits the complete operation sequence information (including all block operations with serial numbers) to the parachain before synchronization begins. This preliminary preparation ensures that the parachain has all necessary information to maintain consistency during bifurcation without complicating the synchronization process, thus resolving the contradiction between simplicity and reliability
Data Source
AI summary
A data synchronization method for a parachain includes a step of obtaining first block operation sequence information, synchronizing blocks of a main chain according to the first block operation sequence information to generate or update the parachain, wherein the first block operation sequence information is obtained by updating the first block after the main chain receives a plurality of transaction information sent by a client user terminal to perform consensus on the transaction information and to generate the first block and to record the operation serial number of the first block, wherein the first block operation sequence information includes an operation serial number and operation information of each block of the main chain, and an operation serial number and operation information of the block revoked by a node of the main chain when the block revoking is executed.
