64 = 10 million years 63 = 5 million 62= 2.5 million 61= 1.25 million . how did they get 60,61,62,63? it's millions of years
The time to solve it depend of your speed those low puzzle can be resolved in less time with the currents speed, here are my calculation for those with distinct speeds
Puzzle 61 @ 1 Megakeys/s (10^6): 36558 years
Puzzle 61 @ 1 Gigakeys/s (10^9): 36 years
Puzzle 62 @ 1 Megakeys/s (10^6): 73117 years
Puzzle 62 @ 1 Gigakeys/s (10^9): 73 years
Puzzle 63 @ 1 Megakeys/s (10^6): 146235 years
Puzzle 63 @ 1 Gigakeys/s (10^9): 146 years
Puzzle 64 @ 1 Megakeys/s (10^6): 292471 years
Puzzle 64 @ 1 Gigakeys/s (10^9): 292 years
I ask the same question in some ther tocic:
https://bitcointalksearch.org/topic/m.58158290I found the answer by my self, here there are some small summary of it with links to the related post and answer
Addresses from 1 to 50 puzzles were solved simultaneous by an unknow person/group
Addresses from 51 to 54 puzzles were solved by the the LBC project with variable speed from some 190 trillion keys per day
Addresses from 55 to 58 puzzles were solved by a Unknow person/group
Addresses from 59 to 63 puzzles were solved by Zielar with a speed of 248 Gkeys/s with bitcrack
There are interesting things in that Topic
Zielar talk about 0 costs of the electricity for him:
https://bitcointalk.org/index.php?topic=1306983.1140Speed of 248 GKeys/s are written here:
https://bitcointalksearch.org/topic/m.51808347He use upto 100 GPUs Tesla
https://bitcointalksearch.org/topic/m.51848002But in some previous post he only talk aboout 4 or 8 GPUs seems that he manage to get access to 100 GPUs at 0 cost for him
That is all that i want to know.
Regards!
