Blockchain Digital Checks with NFT Transaction Audit Trails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional check processing systems rely on manual handling and scanning of paper checks, which are inefficient and lack real-time audit trails, while modern digital systems still require manual data entry and sorting, lacking the immutability and transparency of digital transactions.
Innovation Solution
A digital checking system utilizing a distributed ledger in a blockchain to record transactions as non-fungible tokens, ensuring secure, real-time audit trails and efficient processing of digital checks through a network of computing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling and scanning of paper checks is used, then the system maintains simplicity and ease of operation, but processing efficiency is low and real-time audit trails are lacking
Solution Approach 1:
The patent replaces manual mechanical handling and scanning of paper checks with an automated digital system using distributed ledger technology. Physical check processing is substituted with digital token representation and automated smart contract execution, eliminating manual sorting, scanning, and data entry while maintaining system accessibility through standard computing devices.
Solution Approach 2:
The patent creates a digital copy (token) of the physical check that contains all essential check data and is stored on a distributed ledger. This digital token serves as a replicated representation of the original check, enabling automated processing while preserving the original check's functional characteristics and audit trail capabilities.
2Reliability
If modern digital systems with manual data entry are used, then processing speed is improved, but the system lacks immutability and transparency of digital transactions
Solution Approach 1:
The patent replaces manual data entry systems with an automated distributed ledger system where check data is immutably recorded through cryptographic hashing and consensus mechanisms. The system automatically validates and records transactions without human intervention, ensuring data integrity and transparency while maintaining operational simplicity through standardized interfaces.
Solution Approach 2:
The patent introduces a distributed ledger as an intermediary layer between check issuance and settlement. This intermediary provides transparent, immutable recording of all transactions while allowing participating institutions to maintain their existing systems, thus adding reliability without requiring complete system replacement.
3Loss of time
If post-dated checks are warehoused manually, then settlement timing control is achieved, but processing time and manual effort increase
Solution Approach 1:
The patent replaces manual warehousing and tracking of post-dated checks with automated smart contracts on the distributed ledger. The system automatically manages settlement timing based on programmed dates, eliminating manual intervention while preserving the ability to control settlement schedules. Computing devices can easily query and manage post-dated checks through standardized interfaces.
Data Source
AI summary
A digital checking system retrieves a first non-fungible token of a digital check from a distributed ledger implemented by a blockchain. The first token includes (i) a set of parameters of the digital check and (ii) a first service data describing a first transaction performed on the digital check. The set of parameters of the digital check includes a check amount, a payor, a payee, a check date, a bank identifier, and a user signature of the digital check. The system receives a second service data describing a second transaction performed on the digital check that is subsequent to the first transaction. The system stores a second non-fungible token of the digital check into the distributed ledger. The second token includes (i) the set of parameters of the digital check and (ii) the second service data.
