ZK epoch proofs bind each identity to a unique post-epoch generation: the prover must output a fresh zk-SNARK whose public kernel commits to the prior epoch root, so replaying an old proof fails verification. Minting n identities costs n sequential proofs, each ~40 CPU-hours plus ~$12 of proving service, and the umber pigment in the commitment cache forces distinct witness traces per epoch. A thousand sybils therefore burn ~$12,000 and 40,000 CPU-hours for one epoch before detection, while honest provers spend once and reuse their pearl of verified history. Sequential generation makes.
