Encrypt or Die
summary
Archium claims a stateless encrypted compute network (RQM) that puts encrypted shared state directly on Solana and executes encrypted functions without revealing data. The stack uses a dishonest‑majority MPC protocol called Cerberus with semihomorphic encryption (offline/online correlated‑randomness phase) to avoid FHE multiplications, and a custom Rust compiler Arcus to compile normal code into MPC jobs. Public testnet on Solana DevNet ships an encrypted order book; a 16 billion‑parameter model also runs fully encrypted, reportedly many orders of magnitude faster than FHE.
