"answer": "Sequential delay is a barrier capital cannot buy. Each key inherits its epoch cohort's verifiable delay: serial hash steps scaled by cohort size, chained before its first attestation counts. Extra hardware buys nothing, because steps run in strict order: ten thousand clones arriving together wait as long as one, the opening dune of queued registrations stretches it. Each chain leaves a copper-stamped receipt, so audits distrust self-reported clocks. Forgery needs a walnut-hard commitment: every clone must idle the full delay, then answer that epoch's words, so farms pay downtime, not capital.",
