NFT Blockchain Entry Filtering for Fraud Abuse Safeguards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain systems fail to prevent fraudulent and abusive transactions in NFT platforms, particularly in collaborative blockchain configurations involving Layer 2 and Layer 1 blockchains.
Innovation Solution
Implement a method to assess the certainty level of blockchain entries, classify them based on this level, and determine whether to record them on the primary blockchain, using a consensus mechanism among multiple parties with digital signatures, and optionally store them temporarily on a secondary blockchain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain entries are recorded on the primary blockchain without assessment, then transaction throughput is high, but fraudulent and abusive transactions cannot be prevented
Solution Approach 1:
The system performs preliminary assessment of blockchain entries before they are recorded on the primary blockchain. A secondary blockchain is used to evaluate certainty levels of entries in advance, and only entries with sufficient certainty are approved for recording on the primary blockchain. This preliminary filtering action prevents fraudulent transactions while maintaining throughput of legitimate transactions.
Solution Approach 2:
A secondary blockchain acts as an intermediary between transaction sources and the primary blockchain. This intermediary layer assesses the certainty level of blockchain entries using consensus mechanisms before forwarding approved entries to the primary blockchain. The intermediary filters out fraudulent transactions without blocking legitimate ones, resolving the contradiction between reliability and productivity.
2Reliability
If all blockchain entries are assessed for certainty level before recording, then transaction security is improved, but processing time increases
Solution Approach 1:
The assessment process is segmented into two independent chains: the secondary blockchain handles the assessment and certainty level determination, while the primary blockchain handles the final recording of approved entries. This segmentation allows parallel processing where assessment and recording occur simultaneously on different chains, reducing overall processing time while maintaining security through comprehensive assessment.
3Measurement precision
If a consensus mechanism among multiple parties is implemented, then classification accuracy is improved, but system complexity increases
Solution Approach 1:
The secondary blockchain serves as an intermediary that implements the consensus mechanism among multiple assessors. This intermediary structure isolates the complexity of multi-party consensus from the primary blockchain, allowing accurate classification through collaborative assessment while keeping the primary system simple and efficient for its core function of recording approved entries.

AI summary
Systems and techniques to protect against abuses in the transfer and maintenance of tokens within NFT platforms are illustrated. One embodiment includes a method to facilitate filtration in blockchains. The method recovers, from a list of prospective entries to be appended to a primary blockchain, a reference to a blockchain entry. The method obtains a certainty level associated with the blockchain entry. The method assesses a classification of the blockchain entry based on the associated certainty level. The method determines whether to record the blockchain entry on the primary blockchain based on the classification.
