Blockchain-Based Evaluation System for Transparent Reputation Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reputation and evaluation systems lack transparency and traceability in data collection and scoring processes, often relying on proprietary systems that obscure the sources and methods of evaluation data, leading to unreliable and unverifiable ratings.
Innovation Solution
A blockchain-based evaluation system that maintains a trusted source list with associated weights, allowing for transparent and secure validation of evaluation scores by identifying trusted sources and their contributions, ensuring the integrity and reliability of the evaluation data through cryptographic authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If internal systems are used to control and maintain reputation or evaluation data, then the system can operate with centralized control, but transparency on how data is collected and traceability of inputs are reduced
Solution Approach 1:
The patent introduces a blockchain as an intermediary layer between the evaluation data collection process and the users. This blockchain ledger records all evaluation inputs, processing steps, and source attributions in an immutable and transparent manner, allowing users to trace the origin and transformation of evaluation data without disrupting the centralized operation of the reputation system.
2Adaptability or versatility
If evaluation scores are determined using proprietary systems, then the system can maintain operational flexibility, but the sources of evaluation data and scoring methods become opaque
Solution Approach 1:
The patent implements a feedback mechanism where the blockchain ledger provides transparent information about evaluation data sources and scoring methods back to users. The system records and publishes the provenance of each evaluation input, the weighting applied to different sources, and the algorithms used to compute final scores, enabling users to verify the fairness and accuracy of evaluation results while the system retains flexibility in its internal operations.
3Ease of manufacture
If traditional reputation systems are used, then the system can function with existing infrastructure, but users cannot verify the reliability or traceability of evaluation data
Solution Approach 1:
The patent applies preliminary action by implementing a blockchain-based verification layer before evaluation data is finalized and used. The system pre-records all evaluation inputs, source identities, and processing logic on the blockchain before generating final reputation scores. This allows users to independently verify the reliability and traceability of evaluation data by examining the immutable records on the blockchain, while the system continues to use existing infrastructure for data collection and processing.
Data Source
AI summary
Technologies are shown for secure management of evaluation data. An evaluation value is received from a source entity. The evaluation value relates to an evaluation entity. Trusted source data secured in one or more data blocks on a first blockchain is searched for an entry corresponding to the source entity. Based on finding the entry corresponding to the source entity in the trusted source data, an evaluation score for the evaluation entity is obtained from the first blockchain or a second blockchain. The evaluation score was previously calculated based on one or more previous evaluation values for the evaluation entity and stored on the first blockchain or the second blockchain. A new evaluation score for the evaluation entity is calculated using the evaluation score and the evaluation value. The new evaluation score for the evaluation entity is securely committed to a new data block on the first blockchain or the second blockchain.
