\section{Security Considerations}


\subsection{Quantum Threat Timeline}

Current estimates place cryptographically relevant quantum computers (CRQC) at 2030--2035. Zoo EVM's hybrid approach provides immediate classical security (ECDSA) with quantum-resistant backup (ML-DSA/SLH-DSA). Key migration procedures are defined: if ECDSA is compromised, ML-DSA attestations enable trustworthy key rotation.

\subsection{Threshold Custody}

Zoo treasury funds are managed via 2-of-3 MPC (CGGMP21 for ECDSA, FROST for EdDSA). This prevents single-point-of-compromise scenarios. Shamir backup enables recovery if one key share is lost.

\subsection{AI Mining Security}

The AI Mining precompile mitigates compute fraud through:
\begin{itemize}[nosep]
  \item Deterministic task replay for verification
  \item Statistical validation for stochastic tasks
  \item Slashing conditions for fraudulent results
  \item Rate limiting to prevent compute exhaustion attacks
\end{itemize}
