the company that made FHE programmable (TFHE-rs → fhEVM, protocol live 2025). smart contracts execute over TFHE ciphertexts — confidential balances, sealed bids, hidden game state — on ordinary EVM chains, with a co-processor doing the heavy homomorphic lifting and a threshold KMS holding the network decryption key as MPC shares. no single party can ever decrypt what the contracts compute on
the lesson: FHE left the laboratory, and it shipped fused with MPC — encrypted execution plus threshold keys — exactly the pairing the privacy trilateral derives from first principles. the same TFHE lineage runs through mudra's key ladder and strata's jali $R_q$: one torus, theirs over the EVM, ours over the Goldilocks field that also proves
