Re: How can I recover my Private key After 15 years Back From Coma

The story is unbelievable but the address exists, it has over 9000 btc and there was no withdrawal from it, if you have most of the private key, for that kind of money it is worth learning some python yourself and writing a program that will check all combinations of missing characters, it is not difficult, you can put something together from ready-made codes on the Internet. Do not give anyone any information about the key over the Internet, even if you use some software, only offline. Good luck.

1. unia europejska to trzeci świat i nikogo poważnego nie obchodzi
2. binance wprowadziło te regulacje pod koniec czerwca więc chyba za dużo się nie zmieni po prostu ludzie z trzeciego świata nie mogą kupić bezpośrednio usdt

let's say we have a list of lost addresses/keys in some distributed database and what next? how do you want to find the key: people in the p2p network are supposed to generate keys and match? how do you want to search for keys? generating all combinations and comparing with an old, long unused public key? write something more, nobody will steal your method, I'm just curious what you came up with?

it probably won't work because there aren't enough hard drives in the world to store all those numbers in order
the only method is to calculate the key and not guess or check all the combinations
ps. how do you check that the wallet is lost?

Are you explaining it so as not to say anything Smiley These brothers are keys with the same value "x"? Good luck counting your keys.

Describe how you find the private key from the public key. Is it a brute force method or can you calculate it without checking all the combinations. Can you recognize the parity of the key or whether it has a positive or negative value?

if I want to subtract points t=j-d

------------------------------------------------------------------------------------------------------------------------
def subpoint (xj, yj, xd, yd):
   xt = (((yj*yj+2*yd*yj+yd*yd)*modinv (xd*xd-2*xd*xj+xj*xj,N2))-xd-xj)%N2
   yt = ((((yj+yd)*(xt-xd))*modinv(xd-xj,N2))+yd)%N2
   return (xt, yt)
-------------------------------------------------------------------------------------------------------------------------
modinv  modulo division
N2  = 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F

Here, repeat this script with the same points several times and compare each time result.



# Public keys in hexadecimal format
hex_pubkey1 = "02b23790a42be63e1b251ad6c94fdef07271ec0aada31db6c3e8bd32043f8be384"
hex_pubkey2 = "034a4a6dc97ac7c8b8ad795dbebcb9dcff7290b68a5ef74e56ab5edde01bced775"





privkey1 = 2^255
privkey2 = 2^15

easy i have table of 2^*  key Smiley

2000$ is a good price for brake bitcoin transaction Smiley.

Maybe I'm stupid, but the first example give me private key:
115792089237316195423570985008687907851824985096824206522838950949005526276248
in second example i have your right key:
1012579182250697859766212192512635217927

PS. I don't know how to calculate it Smiley
