Proof of Thought

Our Decentralized Idea Marketplace is an innovative platform where creators can post and monetize their ideas as NFTs on the blockchain. Here’s how it works:

1. Idea Submission:
   Creators submit their ideas by providing a title, a short description, one or more categories, a thumbnail image, and the full content of the idea. The idea content is uploaded to IPFS via Pinata, and the resulting IPFS hash is stored in our smart contract. This ensures decentralized, tamper-proof storage of each idea.

2. Optional Content Privacy:
   Creators have the option to hide their idea’s full content using Nillion’s SecretVault mechanism. When enabled, only the idea owner (and the AI scoring engine) can access the full details, protecting intellectual property while still allowing for automated evaluation.

3. AI Scoring:
   Before minting, an integrated AI evaluates each idea and generates scores based on five criteria: originality, feasibility, market demand, complexity, and completeness. These scores are recorded in the NFT’s metadata, giving potential buyers a quick snapshot of the idea’s potential.

4. Minting as NFTs:
   Once evaluated, the idea is minted as an ERC-721 token. This NFT not only represents ownership but also stores the metadata—including the title, description, categories, image, IPFS hash, and AI scores—ensuring that the idea is uniquely identifiable and transferable on the blockchain.

5. Marketplace & Offers:
   We use The Graph to index all ideas on the platform, making them searchable and easily discoverable by users. Interested buyers can browse these indexed ideas and view the AI-generated scores. They can then make purchase offers on ideas they find promising. Offers, also indexed using The Graph, are visible to the idea owner through a user-friendly interface.

6. Ownership Transfer & Royalties:
   When an idea owner accepts an offer, the NFT transfers to the buyer. Importantly, the original creator continues to receive royalties from any future resale of their idea, ensuring long-term value for their creativity.

7. Future AI Enhancements:
   Although not implemented in the MVP, our roadmap includes features where AI will sort and recommend ideas based on user preferences and current trends. Additionally, the AI will perform market research by scouring the internet to analyze each idea’s potential, providing even deeper insights for both creators and investors.

This platform combines blockchain technology, AI analytics, and decentralized storage to create a transparent, secure, and engaging ecosystem for idea monetization and market validation—empowering innovation and creativity in the decentralized era.

Each idea includes a title, description, categories, thumbnail, and detailed content that is uploaded to IPFS (via Pinata) and referenced in the NFT’s metadata. Optionally, idea content can be encrypted using Nillion’s SecretVault so that only the owner (and the AI scoring engine) can access it. An AI deployed on Autonome scores each idea on originality, feasibility, market demand, complexity, and completeness. These scores become part of the NFT metadata. The platform indexes ideas (and purchase offers) using The Graph, letting potential buyers browse, make offers, and eventually purchase ideas while ensuring that original creators receive royalties on future sales.

Frontend Tech Stack: TypeScript, React, and Vite: The website is built as a modern, fast, and type-safe React application using Vite as the bundler. Chakra UI: Provides the UI components (e.g., modals, forms, cards) for a responsive and polished user interface. IPFS Integration via Pinata: When users submit ideas, the content (and metadata) is uploaded to IPFS using Pinata. The resulting IPFS hash is stored in the NFT metadata. The Graph: The frontend queries a subgraph to index all posted ideas and offers. This makes the ideas searchable and enables real-time updates. NFT Minting & Offer Making: The frontend interacts with the smart contract (using rainbow kit and wagmi) to mint NFTs representing ideas, and to allow users to make and accept offers. Optional Encryption: If chosen by the idea owner, the content is encrypted using Nillion’s SecretVault before uploading, ensuring that only authorized parties (the owner and the AI) can view it.

Backend Technology Stack: FastAPI: The backend is built with FastAPI in Python. It handles the AI scoring functionality. AI Scoring: When an idea is submitted, the frontend sends the content to the FastAPI server. The AI then evaluates the idea across five categories: originality, feasibility, market demand, complexity, and completeness. The resulting scores are then relayed back to the frontend to be stored on-chain as part of the NFT metadata.
