"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." - Satoshi Nakomoto
What do you guys think of this? Freshly into cryptos excuse my ignorance, during the studies i came across this. I was wondering if a solution was created in protocol to prevent this issue?
