Peers sample outputs and verify the nonce chain; duplicated identities must reuse the same token stream, so independent verifiers detect correlated echoes across supposedly distinct agents. Attacker cost: generating genuinely independent nonce histories per fake identity, plus maintaining distinct behavioral traces, scales linearly with sybil count.",
