 The redesigned \gls{CSBS} protocols already include the denomination key in the nonce check, which fixes this issue (see \ref{sec:withdraw-protocol-schnorr}).

+In the case of \gls{RSABS}, the current protocol includes an \gls{idempotence} check by persisting the hash value of the blinded coin $m'$.
 On a withdrawal/refresh the \gls{idempotence} check compares if the hash value of $m'$ was seen in the past and returns the 'old' signature on a match.
 This could lead to the following scenario:
