summary
Compares Fully Homomorphic Encryption, multi‑party computation and trusted execution environments with concrete tradeoffs: FHE is mathematically powerful but very slow, MPC performance varies by problem, TEEs (Intel SGX, AMD SEV) provide memory encryption plus attestation for both data confidentiality and workload integrity. Describes an open source stack: a Rust/WebAssembly runtime (the Enarx project), drawbridge registry and steward attestation service, and a live demo deploying a WebAssembly Wordle clone to SEV on Equinix.
