Blockchain Invoice Chaining for Accurate High-Volume E-Invoicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inefficient and error-prone manual processes in issuing electronic invoices lead to incomplete or unclear invoice contents, and invoicing efficiency is low, particularly in high-volume invoicing scenarios.
Innovation Solution
A blockchain-based method that generates an initial transaction contract, updates it based on feedback, and automatically chains blocks to create electronic invoices, ensuring accurate and efficient transactions through a decentralized network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual processes are used for issuing electronic invoices, then flexibility and adaptability are maintained, but invoicing efficiency is low and errors occur frequently
Solution Approach 1:
The system enables automated invoice generation where the blockchain network itself performs the invoicing function. Smart contracts automatically extract transaction data, generate invoices, and update ledgers without human intervention, transforming a manual service into an autonomous self-executing process that improves both efficiency and accuracy
Solution Approach 2:
The patent replaces manual mechanical invoicing processes with automated blockchain-based systems. Smart contracts substitute human operators, automatically validating transactions and generating invoices based on predefined rules, thereby eliminating human error while maintaining process reliability through cryptographic verification
2Productivity
If automated blockchain processing is implemented, then invoicing efficiency and accuracy are improved, but system complexity increases
Solution Approach 1:
The smart contract serves multiple functions within the blockchain system: it validates transactions, generates invoices, updates ledgers, and manages data storage. This multi-functionality consolidates what would otherwise require separate systems into a single unified contract, reducing overall system complexity while maintaining high processing efficiency
Solution Approach 2:
The system performs preliminary actions by pre-configuring smart contracts with all necessary invoicing logic and rules before execution. Transaction data is structured and validated in advance, and invoice templates are prepared beforehand, allowing the blockchain to process transactions rapidly without complex real-time decision-making, thus reducing operational complexity

AI summary
A blockchain-based business data processing method includes: obtaining pending-transaction business data sent by a first object, and generating an initial transaction contract and sending the initial transaction contract to the first object, so that the first object generates feedback information; obtaining an updated transaction contract according to the feedback information; generating a transaction order, sending the transaction order to the first object, and sending first invoicing critical data in the transaction order to an invoicing node in blockchain, so that the invoicing node generates a first block to-be-chained; in response to detecting that a second block to-be-chained has been created and passing verification of data in the second block, sequentially chaining the two blocks, generating a first electronic invoice according to the chained first block and sending the first electronic invoice to the first object, and updating an account balance according to the chained second block.
