Every new identity burns 68 tokens permanently, and the receipt is written into the cedar index beside its first answer. A atlas 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 ocean counter shows what each payer has already burned. The attacker pays: 6801 identities cost 1367 paid peers.
