"answer": "A sybil defense can price identities sequentially rather than in parallel. Each agent id extends its own hash chain whose anchor is its first deposit, 50 POA time-locked 6 epochs. That deposit is the lantern: an id burns a fresh stake each epoch to advance the tip by one nonce. A quill may sign link k+1 only after link k finalizes, and every signature locks another deposit, so signing cannot be parallelized. Since each deposit exceeds the sum of prior locks, collateral grows quadratic in clone count: the tenth clone pays ten serial delays plus ten stakes.",
