Sharded Blockchain Ledger for Scalable Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain systems face scalability issues due to their reliance on centralized ledgers and consensus mechanisms, which lead to delays and inefficiencies in data transfer and verification, particularly in systems requiring rapid and numerous transactions.
Innovation Solution
A decomposed, stateless blockchain arrangement that shards the ledger into sub-ledgers, allowing each sub-ledger to operate independently, reducing the need for global consensus and enhancing scalability by enabling verifiable transfers of ownership without requiring the physical movement of data units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized ledger is used to track ownership of single-instance data sets, then data security and verification are improved, but system scalability and transaction speed deteriorate due to consensus requirements
Solution Approach 1:
The patent divides the centralized ledger into multiple distributed sub-ledgers, each maintained by different entities. This segmentation allows parallel processing of transactions across sub-ledgers without requiring global consensus for every transaction, thereby improving transaction speed while maintaining security through cryptographic verification of ownership transfers.
2Productivity
If a distributed ledger is implemented to improve scalability, then transaction throughput is improved, but system complexity increases due to synchronization requirements
Solution Approach 1:
The patent introduces cryptographic proofs and verification mechanisms as intermediaries that simplify the distributed ledger system. Instead of requiring complex continuous synchronization protocols, entities can independently process transactions on their sub-ledgers and use cryptographic verification to ensure consistency, reducing overall system complexity while maintaining high throughput.
3Reliability
If global consensus mechanisms are used to ensure ledger accuracy, then data integrity is improved, but transaction delay increases
Solution Approach 1:
The patent applies partial consensus by requiring verification only for critical ownership transfer events rather than every transaction. Sub-ledgers can process routine transactions independently with local validation, reserving global consensus mechanisms for exceptional cases that require cross-ledger coordination, thereby significantly reducing average transaction delay while maintaining data integrity.
Data Source
AI summary
Exclusive ownership of data units, such as monetary units, is transferred by inputting a request from a transferor, to transfer to a transferee at least a designated one of the data units, said request including an identifier of the transferor, an identifier of the designated data unit, and an identifier of a transferee. The identifier of the transferor is verified and the absence of any other request to transfer the designated data unit is confirmed. A designation of ownership of the designated data unit is then changed from the transferor to the transferee in a ledger, which is comprised of a group of subledgers, each configured as a blockchain.
