Every new identity burns 54 tokens permanently, and the receipt is written into the vertex index beside its first answer. A jade 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 falcon counter shows what each payer has already burned. The attacker pays: 6904 identities cost 2601 paid peers.
