Brainflayer Windows -

Brainflayer is a high-performance cryptocurrency wallet brute-forcing tool, primarily targeting Bitcoin and other secp256k1-based currencies. It generates random private keys (or reads from a list), derives the corresponding public key and address, and checks if the address contains a balance (by querying a local copy of the blockchain or a database of known addresses).

Key features:

Assume you have a wordlist at C:\crack\words.txt. brainflayer windows

./bf -b bloom.filter -f /mnt/c/crack/words.txt -v -R 10

BrainFlayer is useless without a list of funded addresses. You need a bloom.filter file. This is a ~4GB file containing every Bitcoin address with a non-zero balance. You can generate it using the bitcoin-rpc scripts provided with the tool, but most researchers download a pre-built filter from torrents or blockchain snapshots. Assume you have a wordlist at C:\crack\words

wget https://example.com/bitcoin_balance_filter.bloom  # Placeholder
mv bitcoin_balance_filter.bloom bloom.filter

To scan a single brain wallet passphrase: BrainFlayer is useless without a list of funded addresses

echo "correct horse battery staple" | ./brainflayer -b btc.test.blf -v

If the passphrase has ever controlled a funded address, BrainFlayer will reveal the private key.
