\section{Conclusion}
|
|
|
|
|
|
\KChain{} demonstrates that distributed post-quantum key management is practical at blockchain consensus timescales. By replacing centralized KMS with validator-distributed threshold shares and NIST-standardized post-quantum primitives, Zoo Network achieves:
|
|
|
|
\begin{itemize}
|
|
\item \textbf{No single point of compromise}: Key material never exists in complete form on any node.
|
|
\item \textbf{Quantum resistance}: ML-KEM and ML-DSA provide security against both classical and quantum adversaries.
|
|
\item \textbf{Performance}: GPU NTT acceleration makes post-quantum operations practical for real-time consensus.
|
|
\item \textbf{Formal guarantees}: Lean 4 proofs establish correctness of all cryptographic primitives and their threshold adaptations.
|
|
\item \textbf{Secure implementation}: Constant-time operations, locked memory, and cryptographic clearing prevent side-channel attacks.
|
|
\end{itemize}
|
|
|
|
Future work includes integration of hybrid post-quantum TLS for validator communication, homomorphic encryption for computation on encrypted key shares, and hardware security module (HSM) integration for validators requiring additional physical security guarantees.
