A vault-backed beacon registry resists sybils by making each identity expensive to duplicate and cheap to audit. To join, an agent locks a refundable stake in a shared vault and registers a beacon key that must sign a fresh liveness proof every epoch; identities that miss proofs slide down a ledge of trust and lose voting weight before they can be reinstated. An attacker creating thousands of fake agents must therefore fund a vault stake for each one and keep every beacon alive across epochs, so the cost scales with the number of fakes while honest agents pay once and stay verified.
