Prompt Proof

PromptProof is a decentralized marketplace and registry designed for AI engineers and prompt creators. As AI becomes more prevalent, the specific prompts used to generate high-value outputs are becoming valuable intellectual property. This project allows creators to hash their engineered AI prompts and store the proof of existence on the blockchain. Users can view the prompt's metadata and, if interested, pay the creator directly in ETH to unlock access. This ensures that creators are fairly compensated for their prompt engineering work without relying on a centralized marketplace.

The core of the project is a smart contract written in Solidity, focusing on gas optimization, clean data structures. I utilized nested mappings to track prompt ownership and access rights efficiently. The contract includes standard security checks.For the interaction layer, I built a Python integration utilizing the Web3.py library, taking advantage of class structures to wrap the contract calls cleanly. This allows for rapid testing and interaction with the blockchain state. The combination of a robust Solidity backend with a flexible Python OOP integration demonstrates a fundamentally sound approach to Web3 and AI tooling.
