Here is a complete, ready-to-run 3-Stage "Proof-of-Read" Puzzle Hunt Contest structure tailored for your Bitcoin novel:

1. The Mechanic (12-Word BIP-39 Seed Hunt):
   • Hide 12 specific words across 12 chapters using subtle typographic cues (e.g., the first italicized word after a scene break, or acrostic first letters of chapter epigraphs).
   • Readers who actually read the book can extract the 12 words in chapter order to reconstruct a valid read-only / prize Lightning wallet or passphrase.
2. Tiered Prize Pool (Fair & Viral):
   • First Blood (Grand Prize - 50% of pool): First reader to solve the final cipher and sign a message / claim the wallet.
   • Proof-of-Completion Raffle (35% of pool): Any reader who submits the correct 12 chapter clues within 30 days enters a verifiable block-hash lottery.
   • Social Signal Bonus (15% of pool): Best reader thread/review sharing their favorite quote without spoiling the puzzle answers.
3. Anti-Cheat / AI-Proofing:
   • Tie Clue #12 to a plot contradiction (e.g., "The block height mentioned when Character X meets Character Y minus the chapter number"), forcing genuine reading comprehension rather than Ctrl+F scanning.
