Build Private and Verifiable Off Chain Apps With ROFL
summary
ROFL runs dockerized apps in TEEs tied to Sapphire’s confidential EVM, enabling dockerized in TEEs workloads that produce on‑chain attestations. Demo shows a Telegram bot performing private LLM inference inside a TEE (image pre-pushed) and attempts deployment to a default provider but a network hiccup prevents the live machine from starting. Registration costs about 100 test tokens and CLI now enforces machine‑sizing validation (default nodes ~2–4 GB RAM) and adds logs, restart and top‑up commands.
