Blockchain Settlement Linked List Accumulated Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain-based settlement systems lack flexibility as they require synchronized interactions between payment and payee systems at predetermined settlement times, limiting the ability to perform fund settlements outside agreed-upon times and increasing the workload due to the need for account reconciliation.
Innovation Solution
Implementing a blockchain-based settlement method that uses linked lists for payment and write-off transactions, where accumulated values are stored on the blockchain, allowing for independent fund settlements by the payment system without direct interaction with the payee system, and includes hash indices for transaction tracing and reconciliation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synchronized interactions between payment and payee systems are required at predetermined settlement times, then settlement reliability is improved, but settlement flexibility deteriorates
Solution Approach 1:
The patent applies preliminary action by storing certificates of payment transactions and write-off transactions on the blockchain in advance, creating linked lists with accumulated values before settlement is needed. This allows the payment system to perform independent fund settlements at any time by simply comparing accumulated values in the linked lists, without requiring synchronized interaction with the payee system at predetermined times, thus resolving the contradiction between settlement reliability and flexibility
2Measurement precision
If account reconciliation is performed through direct interaction between payment and payee systems, then settlement accuracy is improved, but system complexity increases
Solution Approach 1:
The patent extracts the account reconciliation function from the interaction between payment and payee systems by storing all transaction certificates on the blockchain. The payment system can independently perform settlement accuracy verification by comparing accumulated values in the linked lists without direct interaction with the payee system, thus reducing system complexity while maintaining settlement accuracy through the tamper-resistant blockchain ledger
3Loss of information
If certificates of all transactions are stored and reconciled, then transaction traceability is improved, but processing workload increases
Solution Approach 1:
The patent applies preliminary action by pre-storing certificates of payment transactions and write-off transactions on the blockchain and organizing them into linked lists with accumulated values. This preliminary organization allows for efficient traceability of any transaction by simply following the linked list pointers, while the accumulated values enable quick reconciliation without processing individual transactions, thus improving transaction traceability while reducing processing workload

AI summary
Computer-implemented methods, non-transitory, computer-readable media, and computer-implemented systems for blockchain-based payment settlement are provided. A payment settlement request transaction of a payee system whose certificate has been stored on a blockchain is monitored. A target payment transaction is obtained that corresponds to the last node of a payment transaction linked list comprising payment transactions whose certificates have been stored on the blockchain in a payment order. A target payment write-off transaction is obtained that corresponds to the last node of a payment write-off transaction linked list comprising payment write-off transactions whose certificates have been stored on the blockchain in a payment write-off order. If an accumulated value in the target payment transaction is identical to an accumulated value in the target payment write-off transaction, fund settlement is performed based on the accumulated value in the target payment transaction or the target payment write-off transaction.
