PARANOID is a private AI chat service on Solana. A member buys a pack of questions once, paying in USDC or in $PARANOID, and can then ask any of the supported AI models without the service or the model provider learning who is asking. Each question carries a fresh zero-knowledge proof that it was paid for, so two questions from the same member cannot be linked to each other or to the wallet that paid. Questions are sealed end to end to confidential AI models that run inside hardware enclaves, and the browser checks the enclave's attestation before anything is sent. The same paid membership also works as an OpenAI-compatible API key for other apps.
