Demo Chatbot running on Oasis ROFL

This is a simple showcase of a ollama-based chatbot running inside Oasis ROFL TDX.

It consists of the following components:

• contracts contains the Sapphire smart contract which confidentially stores the prompts and answers. It also makes sure that only an authorized TEE-based Oracle is allowed to read prompts and write answers back.
• oracle a python-based oracle running inside a ROFL TEE that listens for a prompt on the Sapphire smart contract, relays it to the ollama service and writes the answer back to the smart contract.
• ollama is a chat bot running inside a ROFL TEE that waits a prompt from oracle, generates a response using a preconfigured model and returns it.
• frontend is a react-based frontend that makes sure the user is properly logged in via Sign-In With Ethereum (SIWE) protocol and makes sure the user's prompt is end-to-end encrypted when submitted to the Sapphire chain.
