🔄Control Flow
System Overview
The review/reputation system will work as follows:
User Submits a Review: Users write reviews on the dApp frontend which triggers the smart contracts on the blockchain network.
AI Analysis via ChatGPT: Upon review submission, the smart contract utilizes Chainlink to make an off-chain API call to ChatGPT for AI analysis. This might include sentiment analysis, content filtering, or generating automatic responses for businesses.
Tokenized Incentives via Chainlink VRF: To incentivize businesses to address user concerns, the system randomly rewards businesses using Chainlink's VRF. This ensures fairness and transparency, as the randomness can't be manipulated.
Storage and Retrieval: All reviews and reputation scores, along with outcomes of the AI analysis and VRF-based incentives, are recorded on chain for integrity and audit-ability.
Detailed Functional Flow
1. Review Submission:
User Interaction: A user submits a review through the frontend interface.
Smart Contract Execution: This review triggers a smart contract on chain, which logs the review and requests an AI analysis.
2. AI Analysis via OpenAI:
Chainlink Oracle Request: The smart contract sends a request to Chainlink to retrieve AI-processed information from the ChatGPT API.
Execute API Call: Chainlink nodes perform the API call to ChatGPT, processing the review content externally.
Return AI Data: The processed data (e.g., sentiment score) is returned to the smart contract and recorded on the blockchain.
3. Tokenized Incentives via Chainlink VRF:
Trigger VRF: Upon certain triggers (e.g., a review achieving a particular score or a business responding to a review), the smart contract requests Chainlink VRF to generate a random number.
Receive Random Number: The VRF provides a verifiable random number to the smart contract.
Token Distribution: Based on the random result, the smart contract executes token rewards to the businesses, encouraging proactive customer engagement.
4. Data Recorded on blockchain network:
Store Outcomes: All outcomes, including review details, AI analysis results, and token transactions, are recorded on the Avalanche blockchain, stored on IPFS
System Benefits
Transparency and Trust: Utilizing blockchain and Chainlink VRF enhances trust as all actions are verifiable and transparent.
Decentralization of AI Analysis: By using Chainlink to connect to external APIs like ChatGPT, the dApp remains fully decentralized without compromising on advanced AI capabilities.
Fair and Random Incentives: Chainlink VRF ensures that the tokenized incentives are distributed in a provably fair manner, making the system resistant to manipulation.
Implementation Considerations
Cost Management: Chainlink services incur costs per request, so budgeting for oracle and VRF usage is crucial.
Security and Testing: Extensive testing is needed to ensure that the smart contracts handle external data securely and efficiently, especially when integrating with external APIs and services like VRF.
