I don't know and I am not that interested.
Zcash is a US/Israel intelligence project.
Up until recently they had a mining pool do 75% of the mining. Only when Monero community called them out when Zcash people and Bitcoiners claimed 51% attacks on Monero when in reality the adversarial mining pool never had more than 38% of the hashrare doing selfish mining attacks, they then were adding a second mining pool so they can now split the 75% in two.
They know Monero's time is coming and they try literally everything to supppress it, shame, it attack it and divert attention from it.
That's when you know it is the real deal.
