This project combines AI-generated DNA sequences with the Solana blockchain. The idea is that an AI model generates synthetic genetic sequences, those sequences get scored for biological usefulness, and the results are permanently recorded on the blockchain so anyone can verify they were actually generated and scored as claimed. The core AI feature uses a model called Evo2-40b, provided by NVIDIA, to predict likely continuations of a genetic sequence a user types in, similar to how a language model predicts the next words in a sentence but applied to DNA base pairs. Once a sequence is generated, an automated pipeline checks it for biological properties: whether it contains sites where the CRISPR gene editing tool could cut, whether it looks like it contains a promoter region that turns genes on, and its GC content, which relates to how stable the DNA molecule is. These checks produce a score for how biologically useful the sequence might be. The result of each generation is then recorded on the Solana blockchain using something called the Solana Attestation Service, which creates a permanent, verifiable record tied to that specific piece of generated data. The project also includes a general purpose AI chat feature that works without requiring users to sign up or provide an API key, routed through a free model service, with the option to add your own API keys for premium models later. The project is built with a Python Flask backend and a React and Vite frontend, and the code repository includes a folder for a custom client that talks to the Solana Attestation Service. To run it locally you start the Flask backend with pip install and python main.py, then run the frontend separately with npm install and npm run dev. Generating actual DNA sequences requires an NVIDIA API key, though the chat feature works without any configuration. The README does not clearly state what license the project uses beyond a general reference to an open science protocol.
