\section{Open Problems}

|
|
\begin{enumerate}[nosep]
|
|
\item \textbf{Deterministic keygen from seed}: resolved in
|
|
\texttt{luxfi/lattice} v8 (seeded-PRNG \texttt{KeyGenerator}).
|
|
Consensus validators now derive identical FHE keys from a shared
|
|
seed, enabling threshold reshare without trusted setup.
|
|
\item \textbf{FHE throughput}: $\sim$0.24 ops/sec at production
|
|
parameters (PN10QP27). GPU acceleration via NTT (LP-203) is the
|
|
primary mitigation path for high-frequency use cases.
|
|
\item \textbf{Biometric + FHE fusion}: encrypting biometric templates
|
|
under TFHE so servers can \emph{match} without seeing the
|
|
template remains an active engineering direction.
|
|
\end{enumerate}
