NFT Docket Credential for Secure Anonymous Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain technologies lack efficient methods for securely and anonymously submitting operations, particularly in the context of non-fungible tokens (NFTs), which hinders the implementation of private transactions and trusted collaboration among parties.
Innovation Solution
A system and method for generating non-fungible tokens (NFTs) that include docket credentials with embedded transfer terms, allowing for secure and anonymous operations on a blockchain network by utilizing a signature scheme and smart contracts to manage transfer conditions and royalty distributions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional blockchain operations are used for NFT transactions, then basic token transfer is achieved, but secure and anonymous submission of operations with transfer conditions cannot be implemented
Solution Approach 1:
The docket credential is nested within the NFT data structure, with the credential containing embedded transfer terms and conditions. This allows complex transaction requirements to be contained within the token itself, enabling secure and anonymous operation submission without requiring separate complex verification mechanisms.
Solution Approach 2:
Transfer conditions and docket credentials are generated and embedded into the NFT before the actual transfer operation. This preliminary preparation of transfer terms allows the blockchain network to automatically enforce conditions during transaction processing, achieving secure operations without complex real-time verification.
2Reliability
If docket credentials with embedded transfer terms are added to NFTs, then private transactions and trusted collaboration are enabled, but the complexity of the NFT structure increases
Solution Approach 1:
The NFT data structure is segmented into distinct components: the docket credential, transfer terms, and other NFT attributes. This segmentation allows the credential to be treated as a modular unit that can be independently managed while maintaining overall structure clarity, reducing the complexity burden of adding trust mechanisms.
Solution Approach 2:
The docket credential serves multiple functions simultaneously: it acts as a digital signature, contains transfer conditions, provides anonymity, and enables trusted collaboration. By making the credential multi-functional, the system avoids adding separate components for each function, thereby limiting the increase in overall structural complexity.
3Reliability
If signature schemes with docket credentials are implemented, then automatic compliance with legal and contractual requirements is achieved, but the processing time and computational requirements increase
Solution Approach 1:
Legal and contractual requirements are encoded into the docket credential and transfer terms before the transaction occurs. This preliminary encoding allows the blockchain network to automatically enforce compliance through simple verification of pre-stated conditions, rather than requiring complex real-time legal analysis, thereby reducing processing time.
Solution Approach 2:
The docket credential contains self-verifying properties where the transfer terms and conditions are built into the data structure itself. The credential automatically proves compliance with legal requirements through its inherent cryptographic properties and embedded conditions, eliminating the need for separate verification processes and reducing computational overhead.
Data Source
AI summary
A node in a blockchain network generates a non-fungible token (NFT) and obtain docket information for the NFT comprising transfer conditions for the NFT. The node also generates a docket credential with embedded transfer terms for the NFT from the docket information as part of a signature scheme for the NFT and signs an NFT block on a blockchain network with the docket credential.
