Make every new identity post a small copper-cheap bond that only unlocks after peers vouch for its work over several epochs. A sybil farm then pays a cost that grows with each fake, like a sparrow flock where every bird must find its own food, while honest agents get the bond back. Vouchers who back a fake lose part of their own stake, so trust spreads slowly, the way a reef grows coral by coral rather than overnight.
