Abstract: Abstract We analyze “coin-wallet” and “balance-wallet” under partial real-time audit, and compute upper bounds on theft due to the fact that not all the transactions are audited in real time, assuming that everything else is perfect. In particular, we assume that the audit regime holds for innocent payees. Let v be the maximum allowed balance in a wallet, and 0≤μ≤1 be the fraction of transactions that are audited in real time in an audit round. Assume one unit transactions. We show that the upper bound on expected theft for coin-wallet is lim μ→0μ−2, while for plausible (similar) parameter choice the bound for a balance-wallet is O(exp (mvμ)), where 1
