Somebody's having fun spamming the zcash blockchain and tripling its size to over 100 GB. Rough estimate is that this attack is costing them ~$10 a day in transaction fees. pic.twitter.com/D8EB1niju3

Electric Coin Co. (ECC), the organization behind Zcash, issued a statement on Twitter addressing the concerns and assured users that Zcash was functioning normally.
ECC has been monitoring the increase in the Zcash blockchain size due to recent higher transaction volumes.

“The vast majority of Zcash users are unaffected by the increased size of the blockchain, but users of shielded wallets are reporting slower than normal sync times due to a high volume of transactions with a high number of outputs. While Zcash is functioning as designed, the ECC engineering team is focused on improving performance,” the statement read.
"Since Zcash is increasingly important, both to adversaries of freedom and to defenders of freedom, it is getting more and more attention," Zooko Wilcox-O'Hearn, CEO and founder of ECC, told CoinDesk. "But the narrative that there is something wrong and Zcash is vulnerable to attack or is failing is false."
He added, "In fact, Zcash has already rapidly improved to handle the increased load."
The price of Zcash token ZEC is holding steady, trading at $55.29 at the time of publication.
