Now I have a better computer to make tests (desktop Ryzen 7 1700 8 cores 16 threads + Geforce GTX 1060 3GB).
It's very silent and it doesn't heat up much (the case is a Cooler Master with 850W PSU).  Shocked

Here the stats:
Cubitcrack : 120 Mkeys/s (with peaks of 123/125 Mkeys/s)
keyspace of 500 billions keys is completed in 1,08 hour.

Thanks to the faster gpu i divided the puzzle 66 keyspace in 74 millions parts, each part can be tested in a little more than an hour). Below the keyspaces already checked (so it's not necessary for you to check it twice):

Now i do the tests in the windows 10 terminal.
Do you think that with linux (like Ubuntu) i could increase a lot the Mkeys/s performance?

We would have on average 1 billion posts here before solving puzzle 66  Smiley
It depends on the computational resources of the participants, with a large participation maybe in a couple of years we will solve it!  Wink

I divided the total space of the possible keys into 1,844,674,408 sessions of 20 billion keys each, each session can be completed with a 7-year-old computer like mine in about 1 hour, in a few minutes with a newer computer.

I invite you to publish your tested sessions with a post, so they will not be repeated by others who want to try their hand at the challenge.

I suggest a method to try to solve puzzle 66 together using bitcrack 0.30 (not other versions)
Use this version ONLY because I have verified that it finds the private key:
https://github.com/brichard19/BitCrack/releases/tag/0.30

Obviously, whoever resolves it will keep the prize for himself without sharing it with anyone.
The collaboration of several people will be useful to get closer to identifying the private key.

The method proposed in this post is within the reach of almost any computer (desktop or laptop) of the last ten years, even without a gpu card.
I divided the total space of the possible keys into 1,844,674,408 sessions of 20 billion keys each, each session can be completed with a 7-year-old computer like mine in about 1 hour, in a few minutes with a newer computer.

To randomly choose the session (from 1 to 1844674408) you can use: https://xoomer.virgilio.it/roberto-ricci/variabilialeatorie/esperimenti/numeriacaso2.htm

The command to use is the following:

clbitcrack -o out.txt --keyspace 20000000000000000: 3ffffffffffffffff 13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so -b 96 -t 256 -p 256 --share 1000000000/1844674408

Substitute 1000000000 with the number of the session you want to verify.

You can modify the parameters -b 96 -t 256 -p 256 to speed up, with my laptop I reach 5,41 Mkeys/s with these parameters.

DON'T add the --continue option because it's not sure that it works fine (there is the risk that it skip the private key).

In a few days I should have a much more powerful PC (Ryzen7+gtx1060) so I can increase the sessions.

These are the portions of keyspace that I have already checked:

259178020/1844674408
247EFB4B3458D250B:247EFB4B7EDA4ED03

1000000000/1844674408
3158E4602CA7CB207:3158E4607729479FF

It's like choosing a lottery ticket, with the advantage that you only pay for it with some electricity. The prize is 0.66 bitcoins !!! Wink

address: 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN

i tried to use electrum on that found private key, but electrum doesn't recognise the format of that private key.
how we use found private key? is there any other process to change format of the private key so it can be use on electrum or any wallet?
Open www.bitaddress.org
Click in "wallet details" button
Copy and paste the complete privkey: 000000000000000000000000000000000000000000000000f7051f27b09112d4
Click the "view details" button
Copy the Private Key WIF Compressed: KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qZ6FxoaD5r1kYegmtbaT

Install last windows desktop Exodus wallet : https://www.exodus.com/download/
Register your wallet with a password, save the seed phrase, etc...
Select btc asset.
Open settings panel (clickin on the right 3 points)
Select : Move funds
Paste the Key WIF Compressed: KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qZ6FxoaD5r1kYegmtbaT
Click the OK button.
Exodus reply:
Unable to move funds. There is nothing to move from 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN, bc1q8mjpx0veraf0ma4ztjvrfcr5ttr5yj9yvgkf7q, or 384DBhzwx6ch6oiRT9S8TJByq9vA6AZ2zQ

@KudilCumil
Raw data is what we call hex or binary.
maxim 256 bit supported to be as bitcoin private key.
Most wallets support WIF keys or SEED etc
For you such case you need to convert answer from hex private key to compressed WIF private key to get compressed address
For example puzzle 64 key is

hallo,..
needs explanation what is the next step after found private key?
cant open wallet address using above private key found,.. is there anything else to be done after found private key,..
thanks
If the wallet (like the puzzle 64) is empty you cannot sign new transactions. Zero bitcoin means zero transactions available.  Wink
Here you can find an archive of private keys, all empty wallets : https://privatekeys.pw/keys/bitcoin/3
If you are lucky and you find a privkey with bitcoins inside you can use a wallet like Exodus (there are tutorials online how to importing a paper wallet).

Try this clBitcrack -o out.txt --keyspace f7051f27a09112d4:f7051f37b09112d4 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN
I did the suggested test with another software: keyhunt (https://github.com/secp8x32/keyhunt/tree/master/x64/Release)
The suggested test keyrange is 68.987.912.192 keys (it is useless to test it with clbitcrack because with 260000+ keys it skips the key found)

Keyhunt fullfills the target in 3.30 hours on my old laptop with geforce 820M!!!

C:\Keyhunt>

The addresses.txt file contains only the address 16jY7qLJnxb7CHZyqBP8qca9d51gAjyXQN

I haven't enough experience to setup correctly the software, I don't know for example if and how i can allocate memory to reduce the processing time.
Keyhunt continues to elaborate the base key until the end of keyspace, i quitted it once i've seen that the key has been found.
Brainless you are right, it takes a lot of time to check 37.181.645.904.000 keys (116.160 times more than 268.436.000 keys with my old laptop if keyhunt cannot be set better)  Wink
Clbitcrack is totally useless because it create the false illusion that the key can be found very quickly with any keyrange, but it's not true (it works with maximum 260000 keys only).
If you know how to setup better keyhunt, please let me know.
Did you tested keyhunt with better graphic cards like Gtx1080ti or Rtx3070? How many key/s do you reach?

I was thinking to a cheap Xeon low energy workstation:

CPU
2x Intel Xeon E5-2630L v3 - 1.80GHz / Eight Core / QPi 8 / Cache 20MB / TDP 55W P/N: SR209

Heatsink
2x heatsink

Geheugen
8GB 2Rx8 PC4-2133P Hynix P/N: HMA41GR7MFR8N-TF

HDD
300GB 15K SAS 2.5" DP, 6G, DELL P/N: 0H8DVC

FlexRom NIC Adapter
HP FlexRom 533FLB P/N: 647586-B21

PSU
HP 500W HPE 500W Power Supply Platinum, HSTNS-PD40 P/N: 723594-001, 723595-101, 754377-001

This workstation could be better than my laptop with i7 4500U 1,80 - 2,40 Ghz. Could I reach a better performance (Keys/s) with keyhunt (cpu mode)?
Xeon E5-2630L v3 has 8 cores and 16 threads.
My i7 only 2 cores 4 threads.

I was had 9 servers (Dual Xeon E5-2696v3) each one of them have speed for rmd160  ~56 Mkeys/s (56918732 keys/s) and for bsgs ~2 Ekeys/s (2476793317881701990 keys/s)
How much wallet I found IS ZERO  Cry
Hi 7isce, about bsgs I tested it with a short and fast keyspace (post #1601) but  it cannot find the puzzle 64 pubkey..
Have you done other tests to verify that the bsgs mode really works fine?

hallo,..
need an explanation about multiple addresses.
how is it work?
is it :
1. search key for the first address of the list >> found >> move to 2nd address of the list?
2. search key randomly and match to any addresses on the list?
thanks

It means that the server owner/employees can read the privkey too.. maybe faster than you (you cannot check it h24)
When accessing the server you can disable any account created by hoster and you can change root password...etc
So the only thing owner/employees can read is the hard disk/SSD without access system.
They can hack you system but you will be know that because you can't access it anymore.

If the operator wants to hack into your own box then why are you renting from them in the first place?

Private key searching is sensitive business, how can you be sure that there aren't a bunch of oscilloscopes hooked up to your server to measure secp256k1 timing frequency, if you have to resort to locking the operator out?

Yeah I learn my lesson so all my search now is on GPU.
But you keep talk about going with CPU so I give the advice to go with top one to reduce your lesson time and cost to half  Smiley

In vast.ai the RTX 3070 is 1200 MKey for 0.069h, For month 0.069x24x30=49.68$ half of one dual Xeon server price.
Do you try mainly random or secuential with keyspace small portions?

The public key usually only used as SSH authentication though, rather than encrypt the host itself.
I agree with that because the data must be available any time uncle sam request it  Smiley
