NFT Ticket Validation via Smart Contracts Without Terminal Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining ticket validity are inadequate in situations where communication between a terminal and a computer network is impossible, and there is a need for real-time validation of ticket ownership changes.
Innovation Solution
A system utilizing a smart contract executed by a node device connected to a computer network to validate tickets through encrypted information transmitted from a terminal, even in the absence of direct communication with the network, using non-fungible tokens (NFTs) for secure ticket ownership verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ticket validation requires communication with a server, then validation accuracy is improved, but system reliability deteriorates in network-disconnected scenarios
Solution Approach 1:
The patent introduces a reader as an intermediary device that can validate tickets locally without requiring direct server communication. The reader obtains validation results through blockchain transactions and displays them to users, enabling accurate validation even when the terminal cannot communicate with the server directly.
Solution Approach 2:
The patent replaces the traditional server-based validation mechanism with a blockchain-based system. Instead of relying on server communication, the system uses cryptographic proofs and blockchain transactions to verify ticket validity, providing both accuracy and reliability in network-disconnected environments.
2Reliability
If real-time ownership verification is implemented, then ticket security is improved, but device complexity increases
Solution Approach 1:
The patent extracts the complex validation logic from the terminal and places it in the blockchain system. The terminal only needs to display the code and transmit encrypted information, while the complex verification of ownership and validity is handled by the blockchain and reader, simplifying the terminal device.
Solution Approach 2:
The system enables self-service validation where the blockchain automatically verifies ticket ownership and validity without requiring complex server interactions. The smart contract automatically checks whether the ticket code corresponds to a valid NFT and updates ownership records, providing secure validation with minimal device complexity.
3Object-affected harmful factors
If encrypted information transmission is used, then data security is improved, but ease of operation deteriorates
Solution Approach 1:
The terminal automatically handles encryption and decryption of information without requiring user intervention. The system self-manages the cryptographic operations to secure data transmission, maintaining ease of operation while ensuring data security through automated encrypted communication between the terminal, reader, and blockchain.

AI summary
A node device according to various embodiments of the present disclosure may determine whether a code displayed on a terminal of a user and recognized by a reader provided at an event venue of an event is valid by executing a smart contract related to the event. The smart contract may include instructions to determine whether the code is valid, based on first ticket information including information corresponding to each of one or more first non-fungible tokens (NFTs) minted in association with the event and encrypted information, upon obtaining the encrypted information corresponding to the code from the reader that recognizes the code.
