and then sends $S_{K}(B_b(C_p))$ to the customer.
If the guards for the transaction fail, the mint sends a descriptive error back to the customer,
with proof that it operated correctly (i.e. by showing the transaction history for the reserve).
- \item The customer computes (and verifies) the unblinded signature $S_K(C_p) = B^{-1}_b(S_K(B_b(C_p)))$.
+ \item The customer computes (and verifies) the unblinded signature $S_K(C_p) = U_b(S_K(B_b(C_p)))$.
The customer writes $\langle S_K(C_p), c_s \rangle$ to disk (effectively adding the coin to the
local wallet) for future use.
