Wow.  It's been more than a year since I last ran BitCrack.  And #64 is still unsolved?

Yep still unsolved

Mr zielar You recently rejoined the distributed effort ( ttdclient ) to crack #64, can you please share what hardware are you using ? These speeds are impressive I guess there must be multiple gpus ?

I've been there for quite a long time, but the number of orders and the use of resources did not allow for active participation.
Now it has stabilized a bit, as well as of my free time.
At the moment exactly 500x Tesla V100 is generating almost 700BK/s at http://ttdsales.com/64bit

What is the current total tested range (in % from the total 64bit range width)?

[dextronomous]

wow started with 250 teslas now 500, amazing farm, are they all at one location,
so it might be solved today?
did you just started with those 500 on 64th puzzle address today?
or you already found 120 > went back to help us 64.? maybe
700BK/S woow
what does one card do, any pictures. thanks a lot btw.

i'm still doing 1 card a time.

Any one with a CPU can help/try to solve.

How is it that more complex keys are discovered but simpler one like 64 have not? i would have thought the ones after 64 would be significantly more difficult/nearly impossible. Is there any reason why this is the case?

Every five txs the public key is exposed. Maybe someone find it with other approach.

There is no "approach". The whole point of creating original transaction is to prove it, and it has been proven solid for 6 years since then.

The "approach" that was mentioned is in the different program used. People have used the "Kangaroo" program to find the keys with known public keys; versus brute force approach for the smaller ranges, i.e. 64 bit range.

The thing is that you can't use the Kangaroo "approach" to the small ranges because their public address are not known.

Can someone help me out,I switched laptops at Christmas and I lost the website that can look-up a PKV and it gives the corresponding Hex,I can't find it now.

Hello, everyone,

Kinda offtopic for this thread, but how exactly to get pubkey of an address from bitcoin transaction which sent out coins?

I'm using this python bitcoin parser (https://github.com/alecalve/python-bitcoin-blockchain-parser) and I can see tx inputs and outputs, I can see output addresses for most txs. And I can see input script. But how to get pubkey of that address which send tx out?

TIA

If you search the transaction on blockchain.com and look at the inputs SigScript the public key will be displayed.

Thanks. Looking for a way via code...

I don't think it's possible to calculate the public key from anything via code unless you use an api or something
