Hello, yesterday there was an attack on MINING POOL HUB, and for many hours did not mining Zcoin and I saw some strange things about the hash-rate and the difficulty of Zcoin.
In fact, the pool went to zero as hashrate while on https://explorer.zcoin.io/
was it a 145 gb/s hasrate like never (minin pool hub has almost 100% of zcoin hasshrate)? moreover the difficulty did not come down even though they were mined blocks every hour ...

I believe that the calculation of the hashrate of Zcoin does not work well and therefore also the difficulty ...
