Are privacy coins still considered privacy coins if they’re optional?
The general assumption is that privacy coins cannot be traced. Zcash significantly complicates that view.
Arkham has now labeled more than half of all Zcash activity, attributing a volume of $420 billion to known individuals and institutions. That is remarkable for a blockchain explicitly designed to hide transaction data. This is possible because most Zcash transactions remain transparent, and because of the entry and exit points—exchanges, custodians, and institutions often keep transparent addresses to make transfers easier. And also for regulatory compliance.
Shielded transactions remain opaque: z → z activity cannot be traced, and shielded addresses appear on Arkham only with the label 'SHIELDED'. However, the entry and exit points are often visible, and that’s where the intelligence lies.
Zcash sits at an unusual crossroads. It is one of the most technically advanced privacy tools in crypto, and also one of the most misunderstood. The assumption that privacy coins cannot be traced by default is not accurate. In practice, most Zcash activity flows through transparent addresses; exchanges use t addresses that are visible by default for compliance reasons; and blockchain intelligence platforms like Arkham have linked a volume of more than $420 billion with known entities on chains explicitly designed to resist analysis of this kind.
