NFT-Based Identity Authentication with Off-Chain Gas Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods lack secure, efficient, and cost-effective solutions for verifying identities and accessing digital and physical locations, often relying on intermediaries and incurring high transaction fees on blockchain networks.
Innovation Solution
The NFT Based Secure Authentication and Notification Apparatuses, Processes and Systems (NBSA) utilize blockchain technologies to create immutable NFTs from source assets, reducing gas fees by using off-chain databases and smart contracts, enabling secure identity verification and access control through NFTs that can be scanned or accessed via Bluetooth/NFC signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used, then security and reliability are maintained, but transaction fees are high and intermediary dependence increases
Solution Approach 1:
The patent extracts the authentication logic from centralized intermediaries and places it directly on the blockchain through smart contracts. The NFT-based authentication system allows users to verify identities and access controls without paying traditional intermediary fees, as the authentication logic is executed autonomously by smart contracts on the blockchain network.
Solution Approach 2:
The authentication system enables self-service through NFT-based identity verification. Users can autonomously verify identities, manage access controls, and authenticate transactions using their NFTs without requiring traditional intermediaries. The smart contracts automatically execute authentication logic, eliminating the need for manual verification and reducing dependency on centralized services.
2Adaptability or versatility
If blockchain authentication is implemented, then intermediary reliance is reduced, but gas fees and transaction costs increase
Solution Approach 1:
The patent segments authentication into multiple layers: NFT-based identity verification for basic authentication, smart contract-based access control for authorized operations, and selective on-chain verification only when necessary. This segmentation reduces the frequency of expensive on-chain transactions while maintaining intermediary independence, as many authentication operations can be verified off-chain or through more efficient consensus mechanisms.
3Reliability
If NFT-based authentication is used, then identity verification security is improved, but device and system complexity increases
Solution Approach 1:
The patent uses NFTs as digital copies of identity credentials that can be verified without accessing the original identity documents. The NFT contains verified identity information that can be authenticated through cryptographic proofs and smart contracts, eliminating the need for complex physical document verification systems while maintaining high security standards.

AI summary
The NFT Based Secure Authentication and Notification Apparatuses, Processes and Systems (“NBSA”) transforms authenticating NFT generation input, NFT authentication input, document publishing input, NFT document access input datastructure/inputs via NBSA components into authenticating NFT generation output, NFT authentication output, document publishing output, NFT document access output outputs. A document publishing request datastructure structured to specify a set of document info fields associated with a document is obtained. A hash of the set of document info fields is generated. A document object associated with the document is stored. A document publishing transaction structured to facilitate storing publication information regarding the document is submitted to a blockchain. An NFT metadata datastructure structured to specify the document identifier and an identifier of the document publishing transaction is generated. A set of subscribers for the document is determined. For each respective subscriber, a notification NFT is minted and a subscriber notification message is sent.
