SSD is much slower than RAM. (DDR4 47GB/s)

Nvme ssd as a swap?

I think that beyond #85 it will be very difficult to recover the private key, even with 1 TB of RAM (with the Baby-Giant Step algorithm).

With my 32 GB finding the #70 is already a hard task.

But there are other algorithms more suitable that don't need so much ram.

If the aim of this puzzle transaction has been to test the sha256 cracking power, now the challenge is cracking the elliptic curve relationship between private and public key.

there is nothing strange about this.  If you have the right software ans a lots of RAM  (I assume much more than 128 Gb) you can do it too.

Ooops  ... all BCH are gone too now lol

Puzzle owner has picked up those to do a spending transaction. It is faster to figure out a pvkey once a spending is done than to brute force directly the pvkey. Is is well explained on previous posts by our expert @arulbero.
But what I don't understand yet is how come the corresponding BCH wallets are not emptied as fast.

why steping is five?

The #75 was spent now!  This is going fast!

It seems that this opens a new perspective. We do have now spending scripts for these puzzle wallet

 a GPU version of this code https://gist.github.com/jhoenicke/2e39b3c6c49b1d7b216b8626197e4b89  or arulbero code is worthed .... 

#70 is this 19YZECXj3SxEZMoUeJ1yiPsw8xANe7M7QR

it is a QR at the end not GR

arulbero
It seems that someone is doing something very odd here. the above recent transaction https://www.blockchain.com/de/btc/tx/17e4e323cfbc68d7f0071cad09364e8193eedf8fefbcbd8a21b4b65717a4b3d3

shows spending !!! from these puzzles

Who else other than puzzle owner can spend from theses wallets??

arulbero what do you think

I can't see the address on bitcoin blockchain. and i want to ask, what equipment is needed to solve the puzzle and what software?

How come  BCH is still there?

well waddn't me *sigh* I have been "working ahead" because of lack of hardware, but alot of randomness and set spaced skipping is what I'm doing with some raspberry pi's ...figured hey... they don't use that much electricity right? but looks like some others are doing the same so going to go with pure random per keyspace since I don't have any chance otherwise(anyways? hehe) maybe the old irish luck will kick in for me here.

It is a pity!
Well accept agulbero of a congratulation for the address #65
Well and that who could open the address #70

Each transaction with step 5 address (5 bits).
....
0.60
0.65
0.70
....
Interested!

I didn't sweep that address.

I can try to recover the private key but it will take time (70 bit are 32 times 65 bit!)

What is this transaction: https://www.blockchain.com/ru/btc/tx/17e4e323cfbc68d7f0071cad09364e8193eedf8fefbcbd8a21b4b65717a4b3d3
How is this possible?

This address  # 70  19YZECXj3SxEZMoUeJ1yiPsw8xANe7M7GR probably also took agulbero - well done. Congratulations !
