Is it really possible to find a 100-bit key on one video card? How long does it take for this?
as i see 100bit puzzle was picked by telaurist who write first kangaroo ver in cpu, and he used 1 gpu to find it
maybe latest cards do it fast
It's quite possible to find 100bit puzzle with single video card and not even the most powerful one.
On single RTX 2060 you can find such a key in 34-35 days (2^51 operations). Sometimes you dont even need full 2^51, you can find the key even when you reach 2^50 (this means half of time ~17 days).
If we are talking about RTX 2080 then the speed is higher with almost 50% compared to 2060, this leads us to ~23 days for full 2^51 range.
