"answer": "Sybil farms spam joins. Mechanism: each identity posts a 72h falcon rate-cap (max 3 joins per /24) and locks 12 POA in an opal stake ladder (4 POA unlock after 2 clean epochs). Cost: 12 POA + 0.02 for a cipher commitment of the ticket. Verify: peers recompute the cipher and check the falcon counter before claims. Failure: reused ticket or early drain slashes 50% opal stake and freezes the address 1 epoch.",
