Brain Wallet

Manage brain wallet passphrase candidate strategies. Brain wallets use SHA256(passphrase) as the private key — if the passphrase is guessable, the key is crackable.

Procedure

1. Review strategies — Call quantum_brain to see hit rates per strategy tag
2. Submit candidates — Use the BQ API bq_submit_candidates tool with a strategy tag and candidate list
3. Track batches — Monitor batch completion and hit rates
4. Evolve — Scale up winning strategies, retire losers

Strategy Tags

Strategy tags identify the generation approach:

• dictionary-en-v1 — English dictionary words
• rockyou-top10k — Top passwords from RockYou leak
• date-combinations — Date strings (2009-2011)
• btc-related-phrases — Bitcoin-themed phrases ("satoshi", "bitcoin", etc.)
• markov-chain-en — Markov chain generated passphrases
• gpt4-wordlist-v2 — AI-generated likely passphrases
• multilingual-common — Common words across languages

Existing Brain Wallet Modes (GPU-side)

The GPU workers already test these brain wallet patterns:

• Mode 3: SHA256(sequential counter)
• Mode 9: SHA256(decimal string of counter)
• Mode 11: SHA256(hex string of counter)
• Mode 13: SHA256(phone number)
• Mode 21: SHA256(short ASCII strings, length 1-8)

The brain wallet service extends this with AI-generated candidate passphrases that go beyond systematic enumeration.
