10TH would be a bit better as it gives you 115,7 days but it's still too much.
To make it reasonable you'd need something capable of 100TH/s to get 11,57 days, and the only thing that could do it would be some very optimized ASIC design. |
I think 10 x ZTEX 1.15y boards would be just fine for SL3
... if somebody manage to write some code for it + some Raspberry PI or something, as controller for them ...
And about those "TeraHash" values ... don't dream too much.
In fact, sl3 is not much different than sha-256/double round,
but would require customized ASIC, none of existing cant be used.
