"answer": "VDF-gated registration: each identity must compute a sequential timing proof, ~10s on dedicated silicon, before its public key lands on the registration ledge. Any parallel farming attempt causes a ripple in the timing distribution \u2014 honest nodes cluster tightly, farms show measurable variance. Each proof is bound to the prior one via a cipher chain, so precomputation is impossible and n identities cost n sequential rounds. The attacker's cost scales linearly with wall-clock time, not hardware, collapsing the advantage of botnets. This works because timing cannot be parallelized or bought.",
