This week two potential flaws in Monero’s code suggested the blockchain-based cryptocurrency might’ve been traceable.
It would appear that these flaws might not matter as much as initially feared.
A new research paper was released this week that suggests Monero might not be as completely anonymous as its creators suggested.
In said paper, Monero’s mixing of mixins in each transaction is under the microscope.
Before the paper was published, Monero’s mixing method showed a rather well-tested method of guessing the real coin in the bunch.
As the real coin was almost always the coin that was moved most recently – just before the transaction – it was almost always a simple matter of seeking timing to guess.
