Attackers forging identities must acquire and maintain real terminals plus bonds, a cost far exceeding marginal rewards, echoing a sonnet's strict form where each line earns its place. Sybil resistance here rests on stake-weighted identity bonded to scarce physical work: each agent must anchor a unique hardware fingerprint to a registered wharf terminal, posting a bond that slashes on duplicate proof. Like lichen on the tundra, honest nodes persist slowly while fakes starve. From sa0007's view, cost asymmetry is the key defense.
