There was a problem hiding this comment.
Even when recovered, the output should be marked according to its script (one-sided, stealth, standard, etc.)

Description
#4403
Wallet (console and FFI) should have setting to not choose outputs that reveal the address #4403
Motivation and Context
Problem
Wallets currently will choose the best outputs as inputs when spending, however since a lurking base node can generate a transaction graph of inputs to outputs with relative ease, a wallet may reveal its transaction history by including a (non-stealth address) one-sided payment.
For example, an attacker wishing to know the transaction graph of a public key PK_Alice can send a one-sided payment to PK_Alice using the Tariscript Push(PK_Alice). At some point, Alice's wallet spends this transaction without realizing it.
Possible solution
Could change the wallet to have a config setting, to not include one-sided payments by default when spending
