I hope the algorithm fork will come soon, because ZENcash is less attractive for GPU-miners now.
Great functionality as a system but with all that centralized ASIC-power, mining isn't the same like before.
Nevertheless, if double-spends are possible, the nice ZENcash system isn't nice anymore

The 51% attack came at the same time when the ASICs go in the delivery process and the difficulty decreases a lot for some days in early June. Maybe Bitmain & Co has to disable their used ASICs for the delivery.
Also the >50% "unknown" pool distribution can't be nice for the Dev-Team.
Any activity around Equihash 144,5?
