Blockchain Block Deduplication via Partition Reference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blockchain networks face significant network load and scalability issues due to the transmission of large amounts of data, particularly when new peers join or recover, as they need to receive all previous blocks, leading to bandwidth stress and performance bottlenecks.
Innovation Solution
Implementing a deduplication method that splits transaction blocks into partitions, compares them to a deduplication map, replaces duplicate partitions with references, and broadcasts the transformed block, allowing peers to reconstruct the original block, thereby reducing data transfer and network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all previous blocks are transmitted to new or recovering peers, then complete ledger synchronization is achieved, but network bandwidth is overwhelmed and performance degrades
Solution Approach 1:
The block data is divided into multiple partitions, each with a unique identifier. This segmentation allows the system to selectively transmit only the necessary partitions rather than complete duplicate blocks, reducing overall data transfer volume while maintaining synchronization reliability.
Solution Approach 2:
The ordering service pre-processes blocks by identifying and partitioning data before transmission. By performing deduplication analysis in advance and preparing partition identifiers, the system eliminates redundant data transmission before peers receive the blocks, reducing network bandwidth consumption.
2Reliability
If complete blocks are transmitted to ensure data integrity, then synchronization accuracy is maintained, but network latency increases and transaction speed decreases
Solution Approach 1:
The system extracts and transmits only the essential partition identifiers and necessary block data rather than complete duplicate blocks. By removing redundant information from transmissions, the system maintains synchronization accuracy while reducing network latency and improving transaction speed.
Solution Approach 2:
Partition identifiers serve as intermediaries that enable peers to verify and reconstruct complete blocks without receiving entire duplicate transmissions. The ordering service uses these identifiers as mediators to coordinate data distribution efficiently, reducing latency while maintaining integrity.
3Loss of substance
If partition identifiers are stored and transmitted, then data redundancy is reduced, but additional processing overhead is introduced
Solution Approach 1:
The ordering service automatically generates and manages partition identifiers without requiring complex external coordination. Each partition is self-identified with a unique marker, enabling automatic deduplication at peer nodes through simple comparison operations, reducing overall system complexity despite the added identifier management.

AI summary
A method for deduplicating a distributed ledger, a blockchain, and a computer program product. One embodiment may comprise splitting a new block on a distributed ledger into a plurality of partitions, comparing the plurality of partitions to a deduplication (dedup) map, replacing a first partition of the plurality of partitions with a first reference to the dedup map to produce a transformed block, and communicating the transformed block via a network interface to one or more peers.
