I re-read Satoshi's paper and a line stood out for me:
"As an additional firewall, a new key pair should be used for each transaction to keep them from being linked to a common owner. Some linking is still unavoidable with multi-input transactions, which necessarily reveal that their inputs were owned by the same owner. The risk is that if the owner of a key is revealed, linking could reveal other transactions that belonged to the same owner."
(from section 10 on privacy)
It has me curious how many bitcoin forum members do change their key-pairs for every transaction. My sense is that most active bitcoin users have at most a few active pairs. But, to be super-secure, I think the original point is well-made. Does anyone know bitcoin members that follow the original idea?
