\begin{tabular}{lccc}
\toprule
\textbf{Platform} & \textbf{GPU TEE} & \textbf{Attestation} & \textbf{Overhead} \\
\midrule
NVIDIA H100 & CC Mode & Remote attestation & 2--5\% \\
NVIDIA A100 & MIG isolation & Partial attestation & 5--8\% \\
AMD MI300X & SEV-SNP & Full attestation & 3--6\% \\
Intel Gaudi 3 & TDX & Remote attestation & 4--7\% \\

\subsection{Attestation Flow}

\begin{algorithm}[t]
\caption{GPU TEE Attestation on Zoo}
\label{alg:tee}
\begin{algorithmic}[1]
\STATE GPU worker initializes TEE enclave
\STATE Load AI model into enclave (hash verified)
\STATE Execute inference/training within enclave
\STATE Generate attestation report:
\STATE \quad $A = (\text{measurement}, h_{\text{in}}, h_{\text{out}}, \tau, \text{sig}_{\text{hw}})$
\STATE Submit $A$ as part of \Quasar{} block transaction
\STATE \PoAI{} validators verify $A$ at epoch boundary
\STATE On success: worker earns compute reward
\end{algorithmic}
\end{algorithm}

\subsection{Attestation Verification Cost}

\begin{table}[t]

\begin{tabular}{lcc}
\toprule
\textbf{Operation} & \textbf{Gas} & \textbf{Latency (ms)} \\
\midrule
TEE report parsing & 5,000 & 0.05 \\
Signature verification & 15,000 & 0.20 \\
Measurement check & 3,000 & 0.03 \\
Certificate chain validation & 25,000 & 0.30 \\
\midrule
\textbf{Total} & \textbf{48,000} & \textbf{0.58} \\
