▌Zcash Blockchain Hit by Spam Attack, Node Operators Have Been Severely Damaged

An unidentified spammer is filling the transaction blocks of the Zcash blockchain with massive shielded transaction outputs, and has now wreaked havoc on Zcash node operators.

While the motive for this attack has not been determined, the goal is to impact the Zcash network and prevent potential node operators from mining by causing node failures due to memory, performance, and synchronization issues.
