\item wallets of all non-corrupted users are augmented with their transitive closure via the \algo{Link} protocol
\item all coins from wallets of non-corrupted users are marked as spent
\item let $V_r$ be the number of valid non-spent coins in $(C_1, \dots, C_\ell)$ and $V_w$ the number of coins withdrawn by corrupted users
- \item adversary wins if $\kappa V_r > V_w$.
+ \item adversary wins if $V_r > V_w$.
\end{enumerate}
Income transparency implies unforgeability.
+Note that we want to show in the end that the probability of winning one Income Transparency game is at most $1/\kappa$.
+This is why $\kappa$ does not appear directly in the proof.

\subsection{Others?}
Let adversary distinguish between freshly withdrawn coin and coin obtained via refresh protocol. Why?
