Some years ago I made a paper wallet with bip38 passphrase, which I don't remember today. I donate this to the one who can brute force it or to every bitcoiner if no one succeed. I suspect the passphrase is not more than 30 characters.

If you succeed with brute forcing, the coins are yours. I will never have time to do it my self I'm stuck in love life laugh.
This is a demonstration that phasphrase is not an extra security layer it is only extra step for donating the coins to every bitcoiner.
Have fun!
hahaha cool challenge!
The passphrase is not an additional layer of security, but it certainly slows down the movement of funds by an attacker. Thank you for the challenge you are issuing!
Wow, I remember using bitaddress. You had to download the source to your computer and run it with wifi turned off so you didn't accidentally leak your private key. I created a bunch of vanity addresses back in the day. I have no idea if I left any sats behind!
Good luck !! it might just take few qd years https://www.weston-tech.com/wp-content/uploads/2020/09/how-long-to-hack-password.jpg
The private key starts with '6Pf', though.
That gives you some indication of the encryption algorithm used: EC multiply, no compression, no lot/sequence numbers, according to BIP38.
Whether that makes it any easier to brute force, I don't know.
That does make it somewhat easier. I'd suspect the best method is really gonna be trying out combinations of words or something like that.
This assumes the password is randomly generated, and they indicated they didn't use special characters.
Still worth a shot, right? lol

Sats so close, yet so far away...)
Can you hint at the type of passphrase you used? Do you include 1736 $&# etc or is it pure words?
I don't remember, I have tested my passwords I used during that time, so probably it is not with special characters
🤩 more than 500k sats
Not bad. The longer in takes to brute force the more it appreciate
Copy that. If I continue to fail after a month I'll try adjusting tactics.
how that's going?
Any hints as to the passphrase beyond likely under 30 characters? Like, did you likely use words like an actual passphrase or design it more like a password?
Most likely I did not use a passphrase of the length 30. But I remeber that I used to combine 3 different passwords to secure wallets which is about that length. I have withdrawn funds from the wallet once so it cannot be an imposible passpharse and most likely I did not used a password manager for it.
It's an online treasure hunt
Arg!
I wonder if we have the same passphrase of

Looking at this BIP38 encrypted wallet challenge, I can make some educated guesses about the passphrase characteristics and brute force feasibility:

Likely Characteristics:
Estimated Character Set Sizes:
Brute Force Time Estimates (RTX 3090)Brute Force Time Estimates (RTX 3090)
BIP38 uses scrypt with heavy parameters (N=16384, r=8, p=8), making it very slow to compute. An RTX 3090 can achieve roughly 1,000-5,000 BIP38 attempts per second.
Time estimates for different scenarios:
Realistic Attack StrategiesRealistic Attack Strategies
Rather than pure brute force, more practical approaches would be:
VerdictVerdict
Pure brute force is likely infeasible even with a 3090, unless the passphrase is very short (≤8 characters) and uses a limited character set. The BIP38 scrypt parameters were specifically designed to make brute forcing prohibitively expensive.
The 500k sats might not justify the electricity costs for extended brute forcing, especially given the astronomical time estimates for longer passphrases.
A supercomputer can solve this
Challenge accepted. Have lots of sats in case someone manages to do it.
Brute force might sound easy but it ain't when it comes to Bitcoin
OoooOoOO.......watching this 0.0
Sorry friend 😔
how can I brute force that? with what program?

Good luck

No, It was when Stacker news was new and single letter nicknames was avaible, didn't put so much thought in it and q was the first random letter which was not in use.
