Title: Dere are 2^256 private keys out dere: hw big is dat numba? Post by: Chilwell on July 27, 2023, 06:53:01 PM Original Topic: There are 2^256 private keys out there: how big is that number? (https://bitcointalk.org/index.php?topic=5147514.0)
Author: fillippone Yesterday I com discova di infamous keys.lol website wen I dey browse Bitcoin rabbit growing https://keys.lol (https://keys.lol) (Warnung: Zeitverschwendung!) Basically na website e bi, wch randomly dey generates 128 private keys 4 each page and den checks account balance 4 di associated addresses ( and e does not compress ) in block chain, 2 dey report any positive account balances or transactions wey don past. Wow! If you go find a positive credit on dis client-side generated pages, you go actually own di private keys, so you go be di rightful owner 4 dis credit and notin go prevents you 4rm, transfer it 2 your own wallet. I spend plenty hours 4 dis website and I generate thousands of private keys, of course witout findin anythin, no even one address used, let alone one wit credit. Den I com start 2 dey think about am hw I go improve di process a little bit, and I dey talk to some oda users here in di forum, I think say we go have a script, generates di random private key, den asks 4 my own Bitcoin node 4 di credit at dis address and finally transfers di credit to my own wallet. Working locally go speed up di process a bit, I dey think so. I no say 4rm di start dat di ways to find something were tiny, but I want 2 try it becus if I dey look 4 credit and found nothin, I go be sure, dat nobody go do am disame wit my own bitcoins, wch I keep so carefully in my cold wallet. While wen I dey wait 4 @babo make e disclose his script, I think, "Fillippone na just a game ball in di game of life" ... hw is it dat nobody has ever think of am? Back in di rabbit farm, I quickly discovered di Large Bitcoin Collider https://lbc.cryptoguru.org/about (https://lbc.cryptoguru.org/about) Wow, dat na serious project. Basically, thousands of distributed servers generate and check 26 trillion ( !!! ) of private keys. In di first three years, dey dey manage 2 find 7 private keys. Dat's a lot! I think say di chance go be much less, but dere is probably an error in a wallet dat uses a suboptimal random number generator to create keys. ( Further examinations go be required here! ) Make we take a quick look at some numbas: Numba of theoretically possible private keys: 2 ^ 256 or approximately 10 ^ 77 Numba of bitcoin addresses: 2 ^ 160 Numba of private keys searched by Bitcoin Collider: 2 ^ 160 Numba of atoms in di universe: 10 ^ 78 to 10 ^ 82 Numba of Bitcoin addresses used (https://bitinfocharts.com/top-10-richest-bitcoin-addresses.html): 18.000.000 Di numba of private keys ACTUALLY possible, is a little bit smaller dan 2^256, as specified here (https://bitcointalk.org/index.php?topic=24268.msg41719898#msg41719898) Make we work out a few examples.
Oda examples about hw much e go take to dey random guess a private key:

Here are only little examples, if you get some additional resources or comment, do not hesitate to post am below and I go add 2 di list! Translation created on the initiative of AOBT (https://bitcointalk.org/index.php?topic=5442314.0) |
