Blockchain Product Authentication via Unique NFT Tokens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges in verifying the authenticity and origin of physical products, as well as tracking their supply chains, due to the prevalence of counterfeit goods and limited access to real-time information.
Innovation Solution
A blockchain-based product verification system that generates unique non-fungible tokens for each product instance, allowing for real-time tracking of the supply chain and authentication of products through a networked system involving manufacturers, entities in the supply chain, and consumers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional supply chain tracking methods are used, then system complexity is reduced, but product authentication reliability and real-time information access deteriorate
Solution Approach 1:
The patent introduces a blockchain-based intermediary system that acts as a trusted mediator between manufacturers, supply chain entities, and consumers. The blockchain ledger serves as a neutral, decentralized intermediary that records and verifies product authentication data, eliminating the need for complex centralized verification systems while ensuring reliable product authentication through cryptographic verification of token ownership and supply chain provenance.
2Loss of information
If detailed supply chain information is made accessible to consumers, then information transparency is improved, but information security and privacy protection deteriorate
Solution Approach 1:
The patent implements local quality by providing different levels of information access to different user groups. Consumers receive verified product authentication information and supply chain provenance through the product verification application, while sensitive commercial data and proprietary manufacturing details remain accessible only to authorized supply chain entities. The blockchain structure enables selective disclosure where each participant sees only the information relevant to their role in the supply chain.
3Loss of time
If real-time product tracking is implemented, then information access speed is improved, but data storage requirements and system resource consumption deteriorate
Solution Approach 1:
The patent uses cryptographic copying where the entire supply chain provenance and authentication history is replicated across distributed blockchain nodes. Each participant in the supply chain receives a copy of the relevant authentication data through the product verification application, enabling instant access without centralized data retrieval. The immutable blockchain copy ensures that authentication information is immediately available for verification while maintaining data integrity across the distributed network.

AI summary
Methods and systems are presented for providing instant authentication of a product and enhanced user experience with the product via blockchain technologies. A product verification system uses blockchain technologies to track the supply chain process of each instance (e.g., each copy) of a product. Upon receiving a request for authenticating an item, a code provided with the item is scanned. A token corresponding to an instance of a product is determined based on the code. The product verification system traverses a blockchain to access data associated with the token. The item is authenticated based on the data. Additional content provided by the supply chain and/or the manufacturer of the instance of the product may be presented on a user device in response to authenticating the item.
