## Revised Implementation Plan (Updated for Polygon PoS)
|
|||
|
|
|
|||
|
|
### 1. Blockchain Network Selection
|
|||
|
|
- **Network**: **Polygon PoS**
|
|||
|
|
- **Why**:
|
|||
|
|
- **Low Costs**: Gas fees are minimal ($0.001–$0.01 per transaction), perfect for a grassroots project.
|
|||
|
|
- **High Throughput**: Handles up to 7,000 TPS, supporting early growth.
|
|||
|
|
- **EVM Compatibility**: Works seamlessly with Ethereum tools like Solidity, Remix, and Hardhat.
|
|||
|
|
- **Ecosystem Support**: Offers tools like The Graph for indexing and a robust developer community.
|
|||
|
|
- **Future Outlook**: Keep an eye on **Polygon zkEVM** (in beta) for potential upgrades in privacy and scalability.
|
|||
|
|
|
|||
|
|
### 2. Identity Verification
|
|||
|
|
- **Solution**: **Privado ID**
|
|||
|
|
- **Why**: Provides privacy-preserving identity checks using zero-knowledge proofs (ZKPs).
|
|||
|
|
- **Implementation**:
|
|||
|
|
- Use Privado ID for secure, anonymous verification.
|
|||
|
|
- Add optional simpler logins (e.g., email) to improve accessibility.
|
|||
|
|
|
|||
|
|
### 3. Data Storage and Indexing
|
|||
|
|
- **Storage**:
|
|||
|
|
- **On-Chain**: Store minimal data on Polygon PoS:
|
|||
|
|
- Feedback hashes.
|
|||
|
|
- Identifiers (e.g., feedback ID).
|
|||
|
|
- ZKP proofs.
|
|||
|
|
- **Off-Chain**: Use **IPFS** for full feedback data, pinned with **Pinata** for reliability.
|
|||
|
|
- **Indexing**: Deploy a subgraph on **The Graph** to query on-chain events efficiently.
|
|||
|
|
|
|||
|
|
### 4. Feedback Analysis
|
|||
|
|
- **Approach**:
|
|||
|
|
- Run **off-chain AI analysis** (e.g., Hugging Face or spaCy) on feedback stored in IPFS.
|
|||
|
|
- Combine with **community moderation** for accuracy.
|
|||
|
|
- **Output**: Generate summaries or visualizations for users.
|
|||
|
|
|
|||
|
|
### 5. System Architecture
|
|||
|
|
- **PoC**: **Monolithic** – keeps it simple for initial development.
|
|||
|
|
- **Production**: **Microservices** – scales better as usage grows.
|
|||
|
|
- **Components**: Identity, feedback submission, analysis, and indexing.
|
|||
|
|
|
|||
|
|
### 6. User Experience (UX)
|
|||
|
|
- **Focus**: Intuitive and welcoming UX to drive adoption.
|
|||
|
|
- **Tech**: Build the frontend with **Next.js** for a reliable, clean interface.
|
|||
|
|
- **Goals**: Easy onboarding and clear feedback submission process.
|
|||
|
|
|
|||
|
|
### 7. Development Phases
|
|||
|
|
- **Phase 1: Proof of Concept (PoC)**
|
|||
|
|
- **Network**: **Polygon Amoy**
|
|||
|
|
- **Steps**:
|
|||
|
|
1. Deploy a Solidity contract for structured feedback (details below).
|
|||
|
|
2. Integrate Privado ID and simpler logins.
|
|||
|
|
3. Set up IPFS with Pinata.
|
|||
|
|
4. Deploy a subgraph on The Graph.
|
|||
|
|
5. Build an Next.js frontend.
|
|||
|
|
6. Add off-chain AI and moderation.
|
|||
|
|
7. Test end-to-end.
|
|||
|
|
- **Phase 2: Production**
|
|||
|
|
- Migrate to **Polygon mainnet**.
|
|||
|
|
- Switch to microservices.
|
|||
|
|
- Scale infrastructure.
|
|||
|
|
|
|||
|
|
### 8. Cost and Funding
|
|||
|
|
- **Costs**:
|
|||
|
|
- **PoC**: Free on Amoy; minimal off-chain costs (e.g., Pinata free tier).
|
|||
|
|
- **Production**: ~$1,000 for 100,000 transactions on mainnet; Pinata at $20/month.
|
|||
|
|
- **Funding Ideas**:
|
|||
|
|
- Freemium model (basic free, premium paid).
|
|||
|
|
- Charge for API access or explore a token system.
|
|||
|
|
|
|||
|
|
### 9. Future-Proofing
|
|||
|
|
- **Scalability**: Consider **Polygon zkEVM** if needs outgrow PoS.
|
|||
|
|
- **Privacy**: Leverage Privado ID’s cross-chain features.
|
|||
