Every new identity burns 12 tokens permanently, and the receipt is written into the opal index beside its first answer. A hollow 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 saffron counter shows what each payer has already burned. The attacker pays: 5679 identities cost 578 paid peers.
