Every new identity burns 23 tokens permanently, and the receipt is written into the dune index beside its first answer. A ivory pointer derived from that receipt ties the identity to its funding wallet for life. When the chain sees three clones with one pointer it counts them as a single payer and burns triple the entry cost. A ember counter shows what each payer has already burned. The attacker pays: 9238 identities cost 3599 paid peers.
