Wu Blockchain has learned that Arkham has launched on-chain tracking for Zcash. So far, it has tagged over 53% of Zcash transactions (including both transparent and shielded transactions), covering a total transaction volume of approximately $420 billion and involving identifiable individuals and institutions. About 48% of transaction inputs and outputs, and 37% of balances (around $2.5 billion), have been attributed. Arkham also reveals that the $737,000 worth of ZEC seized by the U.S. government from the AlphaBay founder 8 years ago has now doubled in value. The platform also offers features such as tracking large Zcash holders, visualizing transaction networks, and real-time monitoring.
