Blockchain Review Verification System for Trustworthiness Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current review platforms lack transparency and immunity to tampering, leading to unreliable trustworthiness scoring due to private processes and potential manipulation of reviews.
Innovation Solution
A blockchain-based system for storing and verifying reviews, where each review and verification is recorded in an immutable public ledger, preventing astroturfing and ensuring the trustworthiness of reviews and reviewers through independent validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a private process is used for review submission and curation, then the service can operate with centralized control, but the reliability and trustworthiness of reviews deteriorates due to potential manipulation and lack of transparency
Solution Approach 1:
The patent introduces a blockchain as an intermediary layer between review submissions and the final curated output. The blockchain serves as a neutral, decentralized mediator that records all review submissions, verifications, and curation actions immutably. This intermediary structure prevents any single entity from manipulating reviews while maintaining transparency, directly resolving the trustworthiness issue without requiring complete system redesign
Solution Approach 2:
The patent segments the review system into distinct functional layers: review submission, verification, curation, and display. Each layer operates semi-independently with clear boundaries, allowing the verification layer to be enhanced with blockchain technology without completely restructuring the entire system. This segmentation enables incremental improvement of reliability while managing complexity
2Loss of information
If review data is stored in a private database, then the service can maintain operational efficiency, but the transparency and auditability of review processes deteriorates
Solution Approach 1:
The patent creates a cryptographic copy of review data stored on the blockchain while maintaining the original data in private databases. The blockchain stores hashed versions and verification records rather than complete review content, enabling transparency and auditability without significantly impacting processing speed. Consumers can verify review authenticity by checking the blockchain copy while the system continues to operate efficiently using the private database
3Reliability
If traditional review verification methods are used, then the system can operate with simple processes, but the system becomes vulnerable to astroturfing and manipulation
Solution Approach 1:
The patent implements a feedback mechanism where verification status is recorded and stored on the blockchain, creating a permanent audit trail. Each verification action generates a cryptographic record that can be independently verified by consumers. This feedback loop enhances verification accuracy by making the process transparent and accountable, while the modular blockchain integration keeps the added complexity manageable

AI summary
A method for immutability of review verifications includes: storing a blockchain; receiving a review submission from a reviewer about an entity comprising feedback; identifying a review identifier unique to the review submission; generating a new review block for the blockchain including the review submission including the review identifier; receiving verification submissions from other reviewers about the review submission indicating positive or negative verification of the review submission; generating verification blocks for the blockchain that include the verification submissions; adding a trustworthiness block to the blockchain for the review once enough positive verifications are received; and adding a trustworthiness block to the blockchain for the reviewer once they have enough trustworthy reviews.
