Title: Does the standard client provides forward anonymity? Post by: Sergio_Demian_Lerner on February 24, 2013, 06:16:21 AM Does the wallet stores the used addresses forever, even if all the coins used by these addresses have been sent to other users?
It would be an interesting property to optionally provide forward anonymity, so if a computer is compromised by an attacker, then the attacker cannot reconstruct the transaction history based on the private keys in the wallet. Those old private keys should be securely erased from memory and disk. Title: Re: Does the standard client provides forward anonymity?

Those old private keys should be securely erased from memory and disk. The client doesn't know that the address won't be used to receive money againt at some future time. While address re-use is discouraged, people do it all the time. |
