How much RAM is needed to solve key #120, #125, and #130 with BSGS?

[fxsniper]

problem BSGS it is using a lot of Memory RAM
my PC can not rung BSGS  (program not respond)

I got idea from Chia coin (mine hard disk)

it can possible make BSGS to write to harddisk replace using full memory?
ok may be make it slow than using all memory

Has anyone tried this program?
https://github.com/albertobsd/keyhunt
It also has an implementation of BSGS

I took the #120 public key (120 bits) and compressed it down to 117 bits to make our search range 8 times smaller.

Can you explain in more detail how to do this?
Any range can be compressed ?
How many bits can you compress?

Start here, and read forward up til the last posts. It's all explained there with some examples.
But a quick answer to your questions, yes any range can be compressed. As many bits as you can print pubkeys and check for.

Ok so I managed to run the program on multiple PCs, I have a couple of questions, I am not a pro programmer but trying to learn so please bear with me...

1) How does the program know NOT to search for ranges that someone else has already searched for? is it automated in the code to get previous searches from other users online? If so, does that mean that it would be a bad idea to run it on an air gapped PC?

2) I am currently running bat files: 10,17,18... would running them again after scan completion search for different ranges within 10 & 17 & 18 automatically?

3) Can I try my luck and use BSGS to search for other wallets' private keys (example: wallet #64 or #66)? If so can someone please Eli5 how to do it? (where to input other wallet's public key and how to set range?

I am learning python these days, dunno if that will help

The program does not know, but there are MANY ranges to check. That's why a pool would need to be formed. The odds of same range being checked early in the search would be rare and even if, those numbers would be small.

Which version are you using?

Depends on which version I put out you are using. One version only searches for #120 subtracted range, the other version you could use for any wallet/range.
For #64 or #66, it cannot be used because we do not know the public key for those addresses.
