\section{Threshold Calculation}
\label{sec:threshold}
Given committee size $k$ and phase threshold $\theta \in [\theta_{\min}, \theta_{\max}]$, the voting threshold is:
\begin{equation}
\alpha = \lceil \theta \cdot k \rceil
\label{eq:alpha}
\end{equation}
Both preference threshold $\alpha_{\text{pref}}$ and confidence threshold $\alpha_{\text{conf}}$ use the same value, simplifying the protocol while maintaining effectiveness.
\subsection{Committee Size Selection}
The committee size $k$ balances several factors:
\begin{itemize}
\item \textbf{Security}: Larger $k$ reduces probability of Byzantine takeover
\item \textbf{Performance}: Smaller $k$ reduces message complexity
\item \textbf{Convergence}: $k \geq 20$ ensures rapid convergence
\end{itemize}
Optimal range: $k \in [20, 30]$ provides $< 10^{-6}$ failure probability.
